Question 1
Regular
The nursing student is preparing to care for an ICU client with shock. The instructor asks the student to name the different categories of shock. Which of the following is a category of shock?
Correct!
Incorrect
The correct answer is: B
Rationale
Distributive shock is a category of shock characterized by abnormal distribution of blood flow, often seen in conditions like septic shock, leading to inadequate tissue perfusion despite normal blood volume.
A: Hypervolemic This term typically refers to an excess of blood volume, which does not classify as a category of shock, as shock involves inadequate perfusion rather than volume surplus.
C: Restrictive This term generally pertains to limitations in heart function or expansion, rather than a recognized category of shock, failing to encompass the mechanisms that lead to shock states.
D: Cardiotonic This term describes medications that enhance cardiac output, not a category of shock itself, as it does not refer to the physiological states classified within shock.

Question 2
Regular
The nurse is caring for a client in shock who is deteriorating. The nurse is infusing IV fluids and giving medications as ordered. What type of medications is the nurse most likely giving to this client?
Correct!
Incorrect
The correct answer is: C
Rationale
Adrenergic drugs. These medications are crucial in managing shock, as they enhance cardiovascular function by increasing heart rate and blood pressure, thereby improving perfusion to vital organs during critical situations.
A: Hormone antagonist drugs. These agents primarily block hormonal actions and are not typically utilized in acute shock management, where immediate cardiovascular support is essential.
B: Antimetabolite drugs. Primarily used in cancer treatment, these medications inhibit cell division and are not applicable in the acute setting of shock, where rapid hemodynamic stabilization is required.
D: Anticholinergic drugs. These medications reduce secretions and increase heart rate but do not directly address the underlying causes of shock or provide the necessary cardiovascular support.

Question 3
Regular
The nurse is caring for a client in septic shock. The nurse knows to closely monitor the client. What finding would the nurse observe when the client's condition is in its initial stages?
Correct!
Incorrect
The correct answer is: A
Rationale
A rapid, bounding pulse. In the initial stages of septic shock, the body compensates for decreased perfusion and blood volume by increasing heart rate, resulting in a rapid and bounding pulse.
B: A slow but steady pulse. This finding typically indicates stable hemodynamics, contrasting with the elevated heart rate associated with the compensatory mechanisms in early septic shock.
C: A weak and thready pulse. This suggests a more advanced stage of shock where circulation is severely compromised, unlike the initial stage characterized by a stronger, more forceful pulse.
D: A slow and imperceptible pulse. Such a pulse indicates critical compromise and is inconsistent with the initial compensatory response seen during the early phase of septic shock.

Question 4
Regular
The nurse is caring for a client with shock. The nurse is concerned about hypoxemia and metabolic acidosis with the client. What finding should the nurse analyze for evidence of hypoxemia and metabolic acidosis in a client with shock?
Correct!
Incorrect
The correct answer is: B
Rationale
Arterial blood gas (ABG) findings should be analyzed for evidence of hypoxemia and metabolic acidosis in a client with shock. ABGs provide crucial information regarding oxygen levels and acid-base status, which are vital indicators of the client’s respiratory and metabolic function during shock. The results help guide appropriate therapeutic interventions.
A: Serum thyroid level findings do not directly indicate hypoxemia or metabolic acidosis, as thyroid hormone levels primarily assess metabolic rate and endocrine function rather than respiratory or acid-base balance.
C: Red blood cells (RBCs) and hemoglobin count findings focus on oxygen-carrying capacity, but they do not give specific insights into the acid-base status or immediate oxygenation levels critical in shock assessment.
D: White blood cell count findings primarily indicate infection or inflammation, which does not directly relate to evaluating hypoxemia or metabolic acidosis, thus lacking relevance in the context of shock evaluation.

Question 5
Regular
The nurse is caring for a client with shock accompanied by lung congestion. How would the nurse position this client?
Correct!
Incorrect
The correct answer is: D
Rationale
Semi-Fowler's with lower extremities raised to approximately $15^{\circ}$ promotes optimal lung expansion and reduces pressure on the diaphragm, aiding in respiratory function while maintaining blood flow stability for the client in shock.
A: Completely supine This position may exacerbate lung congestion by restricting diaphragm movement and compromising respiratory function, which is critical for a client experiencing shock.
B: Low Fowler's with legs flat This position does not provide adequate elevation for the lower extremities, potentially hindering venous return and failing to optimize respiratory mechanics during shock.
C: Supine with lower extremities raised to approximately $45^{\circ}$ While elevating the legs may aid circulation, this angle could overly restrict lung capacity, worsening respiratory issues related to lung congestion.
Correct Answer: D

Question 6
Regular
The nurse is caring for a client who is in neurogenic shock. The nurse knows that this is a subcategory of what kind of shock?
Correct!
Incorrect
The correct answer is: D
Rationale
Neurogenic shock is a subcategory of distributive shock.
Neurogenic shock results from a loss of sympathetic tone, leading to vasodilation and decreased peripheral resistance, characteristic of distributive shock, which encompasses various causes that disrupt blood vessel tone and distribution.
A: Obstructive Neurogenic shock does not stem from physical obstructions in the circulatory system, making this option irrelevant to its underlying mechanisms or classification.
B: Hypovolemic Neurogenic shock does not involve significant fluid loss or decrease in blood volume, which are defining features of hypovolemic shock, thereby disqualifying this option.
C: Carcinogenic The term carcinogenic relates to cancer and its effects, which do not pertain to the physiological processes involved in neurogenic shock, making this choice unsuitable.

Question 7
Regular
The student nurse is being precepted in the ICU. The student is caring for a client in the compensatory stage of shock who is hypovolemic. Which compensatory mechanism is most important in the re absorption and retention of fluid in the body?
Correct!
Incorrect
The correct answer is: C
Rationale
The production of antidiuretic hormone and corticosteroid hormones is the most important compensatory mechanism for fluid reabsorption and retention in the body during hypovolemic shock.
This mechanism promotes water retention in the kidneys and increases blood volume, counteracting the effects of hypovolemia. Antidiuretic hormone encourages water reabsorption, while corticosteroids help maintain vascular integrity and support fluid balance during shock.
A: Activation of renin-angiotensin-aldosterone system This mechanism indeed plays a role in fluid retention but is secondary to the immediate effects of antidiuretic hormone.
B: Secretion of epinephrine and norepinephrine These hormones primarily increase heart rate and vascular resistance, which do not directly promote fluid retention essential during hypovolemic states.
D: Release of catecholamines While catecholamines can enhance cardiac output and peripheral resistance, they do not specifically facilitate fluid retention as effectively as antidiuretic hormone does.

Question 8
Regular
The nurse is assessing a 6-year-old child in the emergency department (ED) who was brought in by the parent. The child was stung by a bee and is allergic to bee venom. The child is now having trouble breathing, and is vasodilated, hypotensive, and has broken out in hives. What does the nurse suspect is wrong with this child?
Correct!
Incorrect
The correct answer is: B
Rationale
The child is having an allergic reaction and going into anaphylactic shock.
Anaphylactic shock is characterized by severe allergic reactions leading to airway constriction, hypotension, and vasodilation, which aligns with the child's symptoms of breathing difficulties, low blood pressure, and hives following a bee sting.
A: The child is having an allergic reaction and going into cardiogenic shock. Cardiogenic shock involves heart failure and poor cardiac output, which does not match the symptoms presented in this case.
C: The child is having an allergic reaction and going into neurogenic shock. Neurogenic shock results from spinal cord injury or disruption, not from allergic reactions, making it an unsuitable diagnosis here.
D: The child is having an allergic reaction and going into obstructive shock. Obstructive shock arises from physical obstruction of blood flow, which is irrelevant to the allergic reaction occurring in this situation.

Question 9
Regular
The nurse is caring for a client in the compensation stage of shock. The nurse knows that one of the body's mechanisms of compensation in this stage of shock is the renin- angiotensin-aldosterone system. What does this system do?
Correct!
Incorrect
The correct answer is: D
Rationale
Restores blood pressure.
The renin-angiotensin-aldosterone system plays a crucial role in maintaining blood pressure during the compensation stage of shock by promoting vasoconstriction and increasing fluid retention, which ultimately enhances blood volume and pressure.
A: Decreases peripheral blood flow. This option misinterprets the system's function; instead of decreasing flow, it aims to enhance blood pressure through vasoconstriction.
B: Increases catecholamine secretion. While catecholamines are involved in the shock response, they are not directly related to the renin-angiotensin-aldosterone system's primary purpose of regulating blood pressure.
C: Increases the production of antidiuretic hormone. Although ADH plays a role in fluid balance, it is not a direct product of the renin-angiotensin-aldosterone system, thus making this option inaccurate.

Question 10
Regular
A client presents to the ED in shock. At what point in shock does the nurse know that metabolic acidosis is going to occur?
Correct!
Incorrect
The correct answer is: D
Rationale
Metabolic acidosis will occur during the decompensation stage of shock.
During decompensation, the body's compensatory mechanisms fail, leading to inadequate tissue perfusion and oxygenation. This results in the accumulation of lactic acid and other metabolic byproducts, causing metabolic acidosis as the body can no longer maintain homeostasis.
A: Compensation This stage involves initial responses to shock, where the body attempts to maintain normal function, thus preventing the onset of metabolic acidosis.
B: Irreversible At this stage, significant organ damage has occurred, and while acidosis may be present, it signifies a terminal phase rather than the onset of acidosis itself.
C: Early Early shock allows for compensatory mechanisms to function effectively, thus preventing the rapid development of metabolic acidosis as the body is still able to maintain some homeostasis.
Correct Answer: D

Question 11
Regular
The nurse is caring for a motor vehicle accident client who is unresponsive on arrival to the emergency department. The client has numerous fractures, internal abdominal injuries, and large lacerations on the head and torso. The family arrives and seeks update on the client's condition. A family member asks, 'What causes the body to go into shock?' Given the client's condition, which statement is most correct?
Correct!
Incorrect
The correct answer is: A
Rationale
The client is in shock because the blood volume has decreased in the system. This condition results from significant blood loss due to the numerous fractures and internal injuries sustained in the motor vehicle accident, leading to inadequate circulation and oxygen delivery to vital organs.
B: The client is in shock because the heart is unable to circulate the body fluids. Although cardiac function can contribute to shock, the primary issue here involves blood volume loss from trauma.
C: The client is in shock because your loved one is not responding and brain dead. Unresponsiveness does not directly explain shock; it is rather a consequence of the underlying physiological trauma and blood loss.
D: The client is in shock because all peripheral blood vessels have massively dilated. While vasodilation can occur in shock, the immediate cause in this situation is the significant reduction in blood volume from injuries.

Question 12
Regular
A nurse is evaluating a mechanically ventilated client in the intensive care unit to identify improvement in the client's condition. Which outcome does the nurse note as the result of inadequate compensatory mechanisms?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Organ damage. Inadequate compensatory mechanisms lead to insufficient oxygen delivery and metabolic disturbances, resulting in cellular injury and dysfunction in vital organs, which is a critical concern for mechanically ventilated patients.
A: Liver dysfunction. While liver function can be affected by insufficient oxygenation, it does not directly indicate inadequate compensatory mechanisms, as liver issues may arise from various other factors unrelated to compensatory failure.
C: Weight loss. Weight loss is not a direct consequence of inadequate compensatory mechanisms; it often results from prolonged illness, poor nutrition, or increased metabolic demands, rather than immediate physiological responses.
D: Unsteady gait. An unsteady gait typically relates to neurological or muscular issues rather than inadequate compensatory mechanisms. It does not directly link to the physiological state of a mechanically ventilated patient.

Question 13
Regular
A client is in a driving accident creating a spinal cord injury. The nurse caring for a client realizes that the client is at risk for which type of shock?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Neurogenic shock occurs when spinal cord injuries disrupt autonomic nervous system function, leading to vasodilation and reduced blood pressure. This condition often results in bradycardia and inadequate perfusion, making it a critical concern for patients with such injuries.
A: Anaphylactic shock arises from severe allergic reactions, characterized by rapid onset and systemic symptoms. It does not correlate with spinal cord injuries, which primarily impact neural function rather than immune responses.
C: Septic shock is a result of systemic infection leading to severe hypotension and organ failure. While serious, it is unrelated to the immediate effects of spinal cord injuries on blood circulation.
D: Obstructive shock occurs due to physical blockage in circulation, such as from pulmonary embolism or cardiac tamponade. This type of shock does not directly stem from spinal cord injury mechanisms.

Question 14
Regular
The nurse is reviewing diagnostic lab work of a client developing shock. Which laboratory result does the nurse note as a key in determining the type of shock?
Correct!
Incorrect
The correct answer is: C
Rationale
Elevated WBC counts, such as 42,000/mm³, indicate an immune response that can suggest the presence of infection or sepsis, key factors in identifying septic shock. Monitoring these levels is crucial for determining shock type and guiding treatment.
A: Hemoglobin: $14.2 \mathrm{~g} / \mathrm{dL}$ Normal hemoglobin levels do not provide insight into the underlying causes of shock, lacking specificity for diagnosis or differentiation between shock types.
B: Potassium: $4.8 \mathrm{mEq} / \mathrm{L}$ Standard potassium levels do not correlate with shock classification, offering minimal information regarding the etiology of shock or the patient's hemodynamic status.
D: ESR: $19 \mathrm{~mm} /$ hour ESR measures inflammation but does not indicate specific shock types, failing to provide immediate, actionable insights into the patient's critical condition.

Question 15
Regular
The nurse is caring for a critically ill client. Which of the following is the nurse correct to identify as a positive effect of catecholamine release during the compensation stage of shock?
Correct!
Incorrect
The correct answer is: B
Rationale
Increased arterial oxygenation. Catecholamines enhance heart rate and contractility, which improves cardiac output and subsequently elevates oxygen delivery to tissues, a crucial factor during the compensation stage of shock.
A: Decreased white blood cell count. Catecholamines do not directly influence white blood cell levels; instead, they primarily focus on cardiovascular responses and tissue perfusion during critical situations.
C: Decreased depressive symptoms. While catecholamines can affect mood, their primary function in shock management relates to physiological responses rather than addressing psychological conditions like depression.
D: Regulation of sodium and potassium. Catecholamines primarily function to manage cardiovascular dynamics rather than directly regulating electrolyte levels, which are influenced by different hormonal systems.
Correct Answer: B

Question 16
Regular
Which compensatory mechanism, during the first stage of shock, does the nurse identify as responsible for stabilization of fluid balance?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Corticosteroid hormones play a crucial role in stabilizing fluid balance during the first stage of shock by modulating the body's response to stress, thereby influencing fluid retention and distribution. Their function is vital for maintaining hemodynamic stability in critical situations.
A: Catecholamines primarily focus on increasing heart rate and vascular resistance, lacking direct involvement in fluid balance stabilization during shock, thus not addressing the fluid homeostasis directly.
C: Renin-angiotensin is mainly involved in blood pressure regulation and does not directly stabilize fluid balance; its primary role is in the body's long-term response to low blood flow.
D: Aldosterone primarily regulates sodium retention and potassium excretion but does not play a significant role in the immediate stabilization of fluid balance during the first stage of shock.

The nurse is caring for a client with highly pigmented skin. Which assessment technique is used to evaluate cyanosis?
Correct!
Incorrect
The correct answer is: B
Rationale
Inspecting the conjunctiva is the best technique to evaluate cyanosis in clients with highly pigmented skin. This area is less pigmented and provides a clearer assessment of oxygenation levels in the blood.
A: Blanch the nailbeds. This technique may not provide accurate results in those with darker skin tones, as pigmentation can obscure changes in color associated with cyanosis.
C: Note dullness in skin color. Dullness in skin color can indicate various conditions, but it does not specifically reflect cyanosis and can be misinterpreted in pigmented skin.
D: Assess the earlobe. While earlobe assessment can indicate hypoxia, its reliability is limited in individuals with darker pigmentation, making it less effective for diagnosing cyanosis.

A ratio of 3:01 is anticipated for fluid replacement in a client experiencing shock. This approach ensures adequate restoration of circulating blood volume, addressing hypovolemia effectively and promoting hemodynamic stability.
A: 1:01 This ratio suggests minimal fluid replacement, which is insufficient for a client in shock, where substantial fluid loss has occurred and requires more aggressive management.
B: 2:01 While this ratio implies an increased fluid replacement, it still falls short of adequately compensating for the significant fluid deficits seen in shock conditions.
D: 4:01 This option indicates excessive fluid replacement, potentially leading to fluid overload, which can complicate the condition and is not typically recommended for shock management.

Question 22
Regular
The nurse is caring for an older adult client receiving dopamine therapy for the treatment of shock. For which complication should the nurse monitor?
Correct!
Incorrect
The correct answer is: D
Rationale
Rapid increase in blood pressure. Dopamine therapy can stimulate adrenergic receptors, leading to vasoconstriction and an increase in heart rate, which may cause dangerously high blood pressure levels in older adults.
A: Hypoglycemia. Dopamine primarily influences cardiovascular function and does not directly affect glucose metabolism, making hypoglycemia an unlikely complication during dopamine therapy in this context.
B: Water intoxication. Dopamine does not cause fluid retention or electrolyte imbalances that lead to water intoxication, so this is not a relevant complication for clients receiving this treatment.
C: Photophobia. Photophobia is not associated with dopamine therapy; it generally relates to ocular or neurological conditions, making it irrelevant in the context of managing shock with dopamine.

Question 23
Regular
The nurse is administering a medication to the client with a positive inotropic effect. Which action of the medication does the nurse anticipate?
Correct!
Incorrect
The correct answer is: B
Rationale
Increase the force of myocardial contraction. This action enhances the heart's ability to pump blood more effectively, crucial for patients needing improved cardiac output due to conditions like heart failure.
A: Slow the heart rate. A positive inotropic effect typically does not result in decreased heart rate; instead, it focuses on strengthening the heart's contractions.
C: Depress the central nervous system. Medications with positive inotropic effects primarily target cardiac function, not the central nervous system, thus having no sedative implications.
D: Dilate the bronchial tree. Bronchodilation pertains to respiratory medications, not inotropic agents, which specifically influence myocardial contractility rather than airway resistance or diameter.

Question 24
Regular
The nurse is caring for a client diagnosed with hypovolemic shock. Which outcome would be the best evidence of an improvement in client condition?
Correct!
Incorrect
The correct answer is: B
Rationale
Alertness in level of consciousness indicates improved cerebral perfusion and oxygenation, which are critical in addressing hypovolemic shock. This outcome reflects better overall hemodynamic stability and recovery in the client’s condition.
A: A rise in blood count does not directly indicate improvement in hypovolemic shock, as blood count changes may lag behind actual clinical recovery and are not immediate indicators of hemodynamic status.
C: Increased heart rate often signifies compensatory mechanisms in response to low blood volume, but it does not necessarily reflect an improvement in overall condition or adequate perfusion.
D: Pulse oxygenation level of 92% suggests some degree of hypoxia, indicating that oxygen delivery may still be inadequate, which is concerning rather than a sign of improvement in the client's status.

Question 25
Regular
The nurse is caring for the client with massive blood loss from a gunshot wound, and type-specific blood is currently not available for transfusion. With little time to spare, which blood type does the nurse infuse?
Correct!
Incorrect
The correct answer is: D
Rationale
Type O- is the universal donor blood type, making it the safest option for transfusion in emergencies when type-specific blood is unavailable. This compatibility minimizes the risk of adverse reactions during critical situations.
A: Type A+ contains A antigens, which could provoke an immune response in a patient with a different blood type, posing serious risks during urgent transfusion scenarios.
B: Type B+ also has B antigens, potentially leading to immunological complications if transfused into a patient lacking these antigens, making it unsuitable in emergencies without type matching.
C: Type A/B- is not universally compatible. Transfusion could cause severe reactions, as neither A nor B antigens should be introduced to a patient not already possessing them.

Question 26
Regular
The nurse is performing hourly assessments on a client in the compensation stage of shock. In documenting the hourly urine output of $40 \mathrm{~mL}$ from the Foley catheter, which nursing action is most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Record $40 \mathrm{~mL}$ as the hourly output. Accurately documenting the urine output is essential for monitoring renal function and assessing the client's response to treatment during the compensation stage of shock.
A: Reposition the client and make sure there are no kinks in the catheter tubing. While this action may help improve output, it does not address the need for immediate documentation.
B: Notify the physician of the hourly output and encourage physician assessment. This option delays necessary action since immediate documentation is critical before further medical intervention can be considered.
D: Notify the family of the urine output. Informing the family does not contribute to the clinical management of the patient and overlooks the priority of documenting vital output data.

Question 27
Regular
The nurse is planning care for a client diagnosed with cardiogenic shock. Which nursing intervention is most helpful to decrease myocardial oxygen consumption?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Maintain activity restriction to bedrest. This intervention is essential in cardiogenic shock as it minimizes physical exertion, thereby reducing the heart's oxygen demand and allowing it to recover more effectively.
A: Limit interaction with visitors. While reducing stress is beneficial, it does not directly impact myocardial oxygen consumption as significantly as restricting physical activity does.
B: Avoid heavy meals. Although this can help prevent gastrointestinal strain, it does not primarily address the crucial need to reduce overall oxygen consumption by the heart.
D: Arrange personal care supplies nearby. This assists in convenience but does not influence myocardial oxygen consumption, which is primarily affected by the level of physical activity.

Question 28
Regular
The community health nurse finds the client collapsed outdoors. The nurse assesses that the client is shallow breathing and has a weak pulse. Emergency medical services (EMS) is notified by the neighbor. Which nursing action is helpful while waiting for the ambulance?
Correct!
Incorrect
The correct answer is: B
Rationale
Elevating the legs higher than the heart helps improve circulation to vital organs, especially when the client exhibits signs of shock such as shallow breathing and a weak pulse. This action can aid in stabilizing the client's condition until EMS arrives.
A: Place a cool compress on head. This action may not address the underlying issue of inadequate blood flow and could exacerbate the client's condition by causing further hypothermia.
C: Shake the client to arouse. Shaking could lead to injury or worsen the client's condition, as it does not provide any supportive care and may increase distress.
D: Cover the client with a blanket. While this may help with warmth, it does not address the critical issue of circulation, which is essential for the client’s recovery.

Question 29
Regular
The nurse is caring for a client in the irreversible stage of shock. The nurse is explaining to the client's family the poor prognosis. Which would the nurse be most accurate to explain as the rationale for imminent death?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Multiple organ failure signifies a critical breakdown of essential bodily functions, leading to an inability to sustain life. In irreversible shock, this failure progresses rapidly, indicating a terminal prognosis for the client.
A: Endotoxins in the system may contribute to shock but do not singularly account for the comprehensive decline in multiple organ function that characterizes imminent death.
B: Limited gas exchange affects oxygen delivery but does not encompass the broader, systemic failures seen in multiple organ failure, which is more indicative of imminent death.
C: Brain death refers specifically to neurological cessation and does not directly illustrate the multi-systemic collapse that occurs in the irreversible shock stage, thus not accurately explaining imminent death.

Question 30
Multiple Choice
A nurse educator is teaching students the types of shock and associated causes. Which combination(s) of shock type and causative factors is correct? Select all that apply.
Correct!
Incorrect
The correct answer is: A,C,D,E
Rationale
A: Hypovolemic shock; blood loss
Hypovolemic shock results from significant fluid loss, with blood loss being a primary cause. Understanding this connection is crucial for recognizing and managing this type of shock effectively in clinical situations.
B: Obstructive shock; kidney stone
Obstructive shock is typically caused by physical obstruction of blood flow, such as pulmonary embolism, rather than a kidney stone, which does not obstruct blood circulation directly.
F: Neurogenic shock; diabetes
Neurogenic shock arises from spinal cord injury or certain forms of trauma, not diabetes. Diabetes primarily affects metabolic processes rather than causing vascular paralysis leading to neurogenic shock.

Question 32
Multiple Choice
The nurse is caring for a client who does not accept blood or blood products. Which nursing action(s) conserves blood? Select all that apply.
Correct!
Incorrect
The correct answer is: A,B,D,E
Rationale
Administer medication to stimulate bone marrow, draw minimum volume of blood for diagnostic tests, and reinfuse the client's own blood via closed circuit container are actions that conserve blood.
Administering medication to stimulate bone marrow enhances the body's natural production of red blood cells, minimizing the need for transfusions. Drawing minimum blood volume reduces the overall amount taken for testing, preserving the client's blood supply. Reinfusing the client’s own blood ensures that no foreign products are introduced while optimizing blood conservation.
C: Administer plasma to expand intravascular volume. This action introduces an external substance rather than conserving the client’s own blood, contradicting the goal of minimizing blood loss.
F: Administer blood product only in an emergency. This option does not involve conserving blood as it suggests using blood products in critical situations, which does not align with the client's wishes against blood transfusion.
