Question 1
Regular
When reviewing the health history of a patient, the nurse will note that a potential contraindication to potassium supplements exists if the patient has which problem?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Renal disease. The kidneys regulate potassium levels in the body; impaired renal function can lead to hyperkalemia, making potassium supplementation hazardous and potentially life-threatening for the patient.
A: Burns. While burns can increase potassium levels due to cellular breakdown, they do not inherently contraindicate potassium supplementation as the body may still manage electrolyte levels effectively.
B: Diarrhea. Diarrhea can lead to potassium loss, often necessitating supplementation rather than contraindicating it. This condition typically requires monitoring and potential replenishment rather than avoidance of potassium.
D: Cardiac tachydysrhythmias. Although tachydysrhythmias can be influenced by potassium levels, they do not directly contraindicate potassium supplements, as certain dysrhythmias can actually improve with appropriate potassium management.

Question 2
Regular
During a blood transfusion, the patient begins to have chills and back pain. What is the nurse's priority action?
Correct!
Incorrect
The correct answer is: C
Rationale
Discontinue the infusion immediately, and notify the prescriber.
This action is vital as chills and back pain may indicate a serious transfusion reaction, necessitating an immediate halt to prevent further complications and ensure patient safety by facilitating appropriate medical intervention.
A: Observe for other symptoms. Monitoring symptoms without immediate action could lead to worsening of the reaction, compromising patient safety and delaying necessary treatment for a potential transfusion reaction.
B: Slow the infusion rate of the blood. Merely slowing the infusion does not address the potential severity of the symptoms, risking further complications and not providing the urgent response needed for the patient's safety.
D: Tell the patient that these symptoms are a normal reaction to the blood product. Minimizing the patient's symptoms can lead to a dangerous underestimation of a serious reaction, preventing timely intervention and appropriate care.

Question 3
Regular
The nurse is working with a graduate nurse to prepare an intravenous dose of potassium for a patient on a regular medical surgical unit. Which statement by the graduate nurse reflects a need for further teaching?
Correct!
Incorrect
The correct answer is: D
Rationale
D: The intravenous potassium dose will be given undiluted. Administering potassium intravenously undiluted poses significant risks, including severe phlebitis and cardiac complications, making it essential to dilute the solution for safety.
A: We will need to monitor this infusion closely. Continuous monitoring is crucial to prevent potential complications, ensuring patient safety during potassium infusion, and addressing any adverse reactions promptly.
B: The infusion rate needs to infuse at 10 mEq/hr. While a safe rate is essential, the specific infusion rate may vary based on institutional protocols and patient factors, requiring assessment.
C: The intravenous potassium will be diluted before we give it. Dilution is standard practice to minimize irritation and ensure safe administration, making this statement reflective of proper nursing protocol and knowledge.

Question 4
Regular
A patient is in an urgent care center and is receiving treatment for mild hyponatremia after spending several hours doing gardening work in the heat of the day. The nurse expects that which drug therapy will be used to treat this condition?
Correct!
Incorrect
The correct answer is: D
Rationale
Oral administration of sodium chloride tablets will be used to treat the patient's mild hyponatremia. This method effectively increases sodium levels safely and conveniently, addressing the imbalances caused by prolonged heat exposure and dehydration from gardening.
A: Oral supplementation of fluids does not directly address sodium levels and primarily focuses on hydration rather than correcting hyponatremia specifically.
B: Intravenous bolus of lactated Ringer's solution is more suited for severe cases of dehydration and electrolyte imbalances, not for mild hyponatremia treatment.
C: Normal saline infusion, administered slowly, is typically reserved for more significant sodium deficits, rather than mild cases where oral sodium chloride is sufficient and safer for the patient.

Question 5
Regular
When monitoring a patient for signs of hypokalemia, the nurse looks for what early sign?
Correct!
Incorrect
The correct answer is: D
Rationale
Muscle weakness. This symptom is a hallmark early sign of hypokalemia, reflecting the impact of low potassium levels on muscle function, particularly in skeletal muscles, which can lead to decreased strength and endurance.
A: Seizures. Though seizures can occur with severe electrolyte imbalances, they are not a typical early sign of hypokalemia and are more commonly associated with other conditions.
B: Cardiac dysrhythmias. While cardiac dysrhythmias may develop with significant potassium deficiency, they are generally later manifestations rather than initial indicators of hypokalemia and may not present early on.
C: Diarrhea. Diarrhea can contribute to potassium loss but is not a direct early sign of hypokalemia; it is more of a potential cause rather than a symptom of the condition itself.

Question 6
Regular
During an infusion of albumin, the nurse monitors the patient closely for the development of which adverse effect?
Correct!
Incorrect
The correct answer is: C
Rationale
Fluid volume overload. This condition can arise from the administration of albumin, as it increases intravascular volume. Nurses must vigilantly observe patients for signs such as increased blood pressure, edema, and respiratory distress during infusion.
A: Hypernatremia Increased sodium levels are not a primary concern with albumin infusions; hypervolemia is more pertinent. Monitoring focuses on fluid balance rather than solely on sodium concentration.
B: Dehydration Administering albumin typically aims to expand volume, not deplete it. Dehydration occurs from fluid loss, contrasting with the intended effects of volume expansion during infusion.
D: Transfusion reaction This adverse effect relates specifically to blood products, not albumin. The potential reactions associated with transfusions differ significantly from those concerning albumin administration, making this option irrelevant.

Question 7
Regular
A patient is receiving an infusion of fresh frozen plasma. Based on this order, the nurse interprets that this patient has which condition?
Correct!
Incorrect
The correct answer is: C
Rationale
Coagulation disorder. Fresh frozen plasma is administered primarily to address deficiencies in clotting factors, indicating that the patient likely has a coagulation disorder requiring this specific treatment to restore hemostatic function.
A: Hypovolemic shock This condition typically necessitates volume resuscitation with crystalloids or blood products, but fresh frozen plasma specifically targets clotting factors rather than volume replacement alone.
B: Anemia Anemia usually requires red blood cell transfusions rather than fresh frozen plasma, as the plasma does not directly address the deficiency in hemoglobin levels associated with anemia.
D: Previous transfusion reaction A prior transfusion reaction would prompt careful monitoring and possibly avoidance of transfusions, rather than indicating a need for fresh frozen plasma as a treatment choice.

Question 8
Regular
The nurse is preparing to transfuse a patient with a unit of packed red blood cells. Which intravenous solution is correct for use with the PRBC transfusion?
Correct!
Incorrect
The correct answer is: B
Rationale
0.9% sodium chloride (NS) is the correct intravenous solution for use with the PRBC transfusion.
NS is isotonic and compatible with packed red blood cells, ensuring proper hydration and electrolyte balance during the transfusion. It maintains osmotic stability, preventing hemolysis and supporting optimal circulation, which is essential for effective transfusion therapy.
A: 5% dextrose in water (D5W) introduces hypotonicity, which can lead to cell lysis and is unsuitable for blood component transfusions, as it potentially disrupts red blood cell integrity.
C: 5% dextrose in 0.45% sodium chloride (D5NS) also possesses hypotonic characteristics, risking hemolysis and adversely affecting the transfusion process, making it inappropriate for packed red blood cells.
D: 5% dextrose in lactated Ringer's solution (D5LR) contains additives that could interfere with red blood cell functionality during transfusion, compromising the intended therapeutic effect and stability of the blood product.

Question 9
Regular
The nurse is preparing to transfuse a patient with a unit of packed red blood cells. Which patient would be best treated with this transfusion?
Correct!
Incorrect
The correct answer is: B
Rationale
A: A patient with a coagulation disorder Transfusing packed red blood cells does not address the underlying issue of coagulation disorders, which require specific factor replacement rather than red blood cell support.
C: A patient who has lost a massive amount of blood after an accident While this patient may benefit from a transfusion, packed red blood cells alone may not sufficiently restore blood volume or address shock.
D: A patient who has a clotting-factor deficiency Packed red blood cells do not provide the necessary clotting factors, which are essential for managing deficiencies and ensuring proper hemostasis in affected patients.
Correct Answer: B

Question 10
Regular
After a severe auto accident, a patient has been taken to the trauma unit and has an estimated blood loss of more than 30% of his blood volume. The nurse prepares to administer which product?
Correct!
Incorrect
The correct answer is: B
Rationale
Whole blood is the appropriate product to administer after a severe auto accident with significant blood loss. It contains red blood cells, plasma, and platelets, providing comprehensive support for restoring blood volume and clotting factors.
A: Albumin lacks sufficient red blood cells and platelets, making it unsuitable for significant blood loss where immediate restoration of these components is crucial for patient survival.
C: Packed red blood cells primarily supply oxygen-carrying capacity but do not restore plasma volume or clotting factors adequately, which is essential in cases of extensive blood loss.
D: Fresh frozen plasma contains clotting factors but does not address the need for red blood cells, which are critical for oxygen transport in a trauma situation with severe blood loss.
Correct Answer: B

Question 11
Regular
A patient who is severely anemic also has acute heart failure with severe edema due to fluid overload. The prescriber wants to raise the patient's hemoglobin and hematocrit levels. The nurse anticipates that the patient will receive which blood product?
Correct!
Incorrect
The correct answer is: C
Rationale
Packed red blood cells are the appropriate blood product to raise the patient's hemoglobin and hematocrit levels.
This choice directly addresses the patient's severe anemia by providing a concentrated source of red blood cells, which enhances oxygen transport in the blood, thereby improving the patient's overall condition while being mindful of fluid overload due to heart failure.
A: Fresh frozen plasma does not significantly increase hemoglobin or hematocrit levels; it is primarily used to restore clotting factors and manage coagulopathy rather than treat anemia directly.
B: Albumin serves to expand plasma volume and manage edema but does not contribute to increasing red blood cell count or improving oxygen delivery in an anemic patient.
D: Whole blood contains red blood cells along with plasma and other components, but it is not the preferred method in modern practice for addressing anemia when packed red blood cells are available.

Question 12
Regular
The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Serum potassium level. Evaluating the serum potassium level is essential before administering a potassium supplement to avoid hyperkalemia, which can lead to serious cardiac complications and other health issues if potassium levels are already elevated.
A: Complete blood count. This test primarily assesses overall health and detects various disorders but does not provide necessary information regarding potassium levels specifically.
C: Serum sodium level. While important for assessing electrolyte balance, serum sodium levels do not directly reflect potassium status and do not indicate the need for potassium supplementation.
D: Liver function studies. These tests evaluate liver health and function but are unrelated to potassium levels, thus providing no relevant information for potassium supplementation.

Question 14
Calculation(ans only)
The order reads, 'Give 1500 mL of normal saline over 12 hours. The tubing drop factor is 15 gtt/mL.' The nurse will set the gravity drip infusion at how many drops per minute (gtt/min)?
Correct!
Incorrect
The correct answer is: 31 GTT/MIN
Rationale
31 gtt/min
To calculate the drops per minute, first determine the total volume in mL (1500 mL) divided by the total time in minutes (720 minutes). Then, multiply this rate by the drop factor (15 gtt/mL), resulting in 31 gtt/min, which accurately reflects the required infusion rate for the given parameters.
A: 12 gtt/min This option significantly underestimates the required infusion rate, failing to account for the total volume and the necessary drop factor over the specified duration.
B: 45 gtt/min This choice overestimates the drops per minute, neglecting the correct calculation of total volume divided by time and the drop factor, leading to an inflated rate.
C: 60 gtt/min This figure greatly exceeds the appropriate calculation, disregarding the total infusion duration and volume, resulting in an unnecessarily high and inaccurate drip rate.
