Question 3
Regular
The nurse is caring for a patient in the emergency department (ED) with massive trauma and possible spinal cord injury. Which of the following findings by the nurse will help confirm a diagnosis of neurogenic shock?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Apical heart rate 48 beats/minute. This finding suggests bradycardia, a hallmark of neurogenic shock due to disruption of autonomic regulation following spinal cord injury, indicating decreased sympathetic tone and altered heart rate control.
A: Cool, clammy skin. This symptom typically aligns with hypovolemic or cardiogenic shock, where peripheral vasoconstriction occurs, contrasting with neurogenic shock, where skin may remain warm and dry.
B: Inspiratory crackles. Presence of crackles indicates potential pulmonary complications or fluid overload, unrelated to the neurogenic shock diagnosis, which primarily affects cardiovascular responses rather than respiratory functions.
D: Temperature 38.4┬░C (101.1┬░F). Elevated temperature suggests infection or inflammatory response rather than neurogenic shock, where body temperature regulation is impaired, often leading to hypothermia instead of fever.

Question 9
Regular
Which of the following findings is the best indicator that the fluid resuscitation for a patient with hypovolemic shock has been successful?
Correct!
Incorrect
The correct answer is: B
Rationale
Urine output is 60 mL over the last hour. This finding indicates adequate renal perfusion and effective fluid resuscitation, demonstrating that the circulatory system has improved enough to maintain kidney function.
A: Hemoglobin is within normal limits. Normal hemoglobin levels do not provide direct evidence of effective fluid resuscitation, as they may not reflect recent changes in blood volume or fluid status.
C: Pulmonary artery occlusive pressure (PAOP) is normal. A normal PAOP does not necessarily correlate with successful fluid resuscitation, as it measures left atrial pressure, which may not reflect systemic perfusion accurately.
D: Mean arterial pressure (MAP) is 65 mm Hg. While MAP is a key indicator of perfusion, a reading of 65 mm Hg may still signify inadequate perfusion, especially in severely ill patients.

The nurse is caring for a patient with neurogenic shock who is receiving a phenylephrine infusion through a left forearm IV. Which of the following assessment information obtained by the nurse indicates a need for immediate action?
Correct!
Incorrect
The correct answer is: A
Rationale
The patient's IV infusion site is cool and pale. This indicates potential infiltration or compromised circulation, which is critical in a patient receiving phenylephrine, as it can lead to ineffective medication delivery and further complications.
B: The patient has warm, dry skin on the extremities. This finding suggests adequate perfusion and is consistent with neurogenic shock, indicating the body’s response rather than an immediate concern.
C: The patient has an apical pulse rate of 58 beats/minute. Although bradycardia may require monitoring, it does not signify an immediate threat to the patient's safety in this context.
D: The patient's urine output has been 20 mL over the last hour. While this output is low, it does not necessitate immediate action compared to the pressing issue of the IV site.

Question 22
Regular
Which of the following interventions should the nurse implement first when a patient in the emergency department develops anaphylactic shock?
Correct!
Incorrect
The correct answer is: C
Rationale
Administer epinephrine 0.3 mg intramuscularly. This intervention is critical as epinephrine counteracts the severe vasodilation and bronchoconstriction associated with anaphylactic shock, effectively restoring hemodynamic stability and improving respiratory function.
A: Administer normal saline 500 mL IV. While fluid resuscitation is important, it does not address the immediate life-threatening respiratory and cardiovascular effects of anaphylaxis.
B: Insert a second IV catheter. Establishing an additional IV line can be beneficial but does not prioritize the urgent need for epinephrine to treat anaphylaxis.
D: Start a dopamine infusion at 5 mcg/kg/minute. Dopamine is not the first-line treatment for anaphylaxis; it may not effectively reverse the symptoms of this severe allergic reaction.

Question 23
Regular
The nurse is caring for a patient who is receiving vasopressin to treat septic shock. Which of the following assessments is most important for the nurse to communicate to the health care provider?
Correct!
Incorrect
The correct answer is: B
Rationale
The patient is complaining of chest pain.
Chest pain can indicate serious complications such as myocardial ischemia or other cardiovascular issues, particularly in patients with septic shock receiving vasopressin. This symptom requires immediate communication to ensure timely intervention and prevent further deterioration of the patient's condition.
A: The patient's heart rate is 108 beats/minute. While tachycardia is notable, it is a common response in septic shock and may not indicate an immediate life-threatening issue.
C: The patient's peripheral pulses are weak. Weak pulses can signify reduced perfusion, but they are not as urgent as chest pain, which may indicate critical cardiac distress requiring swift action.
D: The patient's urine output is 15 ml/hour. Low urine output suggests potential renal impairment but is typically monitored over time and is less acute than the immediate risk of chest pain.

Question 24
Multiple Choice
The nurse is caring for a patient with neurogenic shock that has just arrived in the emergency department after a diving accident. He has a cervical collar in place. Which of the following actions should the nurse take? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,B,C,E
Rationale
Prepare to administer atropine IV, obtain baseline body temperature, prepare for intubation and mechanical ventilation, and administer high-flow oxygen (100%) by non-rebreather mask.
Atropine helps manage bradycardia caused by neurogenic shock. Assessing baseline body temperature is crucial due to potential hypothermia. Intubation and mechanical ventilation are necessary for respiratory support. High-flow oxygen addresses hypoxia, improving oxygenation in critical situations.
D: Administer large volumes of lactated Ringer's solution. Excessive fluid resuscitation can exacerbate complications in neurogenic shock, where vasodilation leads to hypotension, requiring careful volume management.

Question 25
Drag and Drop
The health care provider prescribes the following actions for a patient who has possible septic shock with a BP of 70/42 mm Hg and oxygen saturation of 90%. In which order will the nurse implement the actions?
Drag and drop to arrange in correct order:
A.
Obtain blood and urine cultures
B.
Give vancomycin 1 g IV
C.
Infuse vasopressin 0.01 units/minute
D.
Administer normal saline 1000 mL over 30 minutes
E.
Titrate oxygen administration to keep O2 saturation >95%
Correct!
Incorrect
The correct answer is: E,D,C,A,B
Rationale
E: Titrate oxygen administration to keep O2 saturation >95%. Initiating oxygen therapy is crucial to improve tissue oxygenation in septic shock, where the patient's saturation is already low at 90%.
D: Administer normal saline 1000 mL over 30 minutes. Fluid resuscitation is essential, but it follows ensuring adequate oxygenation first to stabilize the patient’s condition effectively.
C: Infuse vasopressin 0.01 units/minute. While vasopressin is vital for managing blood pressure, fluid resuscitation should precede its administration for optimal hemodynamic response.
A: Obtain blood and urine cultures. Cultures are important for diagnosis; however, they should occur after initial stabilization measures are taken to avoid delay in treatment.
B: Give vancomycin 1 g IV. Antibiotic therapy is critical but should follow initial interventions that prioritize oxygenation and fluid status to address the immediate life-threatening conditions.
