Critical Care Nursing Questions and Answers PDF Questions

Question 1 of 5

The patient has been admitted to the hospital with nausea and vomiting that started 5 days earlier. Blood pressure is 80/44 mm Hg and heart rate is 122 beats/min; the patient has not voided in 8 hours, and the bladder is not distended. The nurse anticipates a prescription for �stat� administration of

Correct Answer: B

Rationale: The correct answer is B: fluid replacement with 0.45% saline. The patient's low blood pressure, tachycardia, and lack of urine output indicate hypovolemia. Fluid replacement with saline will help restore circulating volume, improve blood pressure, and support renal perfusion. A: Blood transfusion is not indicated as the primary issue is hypovolemia, not anemia. C: Inotropic agents are used to increase cardiac contractility but are not the initial treatment for hypovolemia. D: Antiemetics may help with symptoms but do not address the underlying issue of fluid loss and hypovolemia.

Question 2 of 5

After the return of spontaneous circulation following the resuscitation of a patient who had a cardiac arrest, therapeutic hypothermia is ordered. Which action will the nurse include in the plan of care?

Correct Answer: A

Rationale: The correct answer is A: Apply external cooling device. Therapeutic hypothermia is a treatment used to protect the brain after cardiac arrest by lowering the body temperature. The nurse should use external cooling devices, such as cooling blankets or ice packs, to achieve and maintain the desired temperature. This method allows for precise temperature control and monitoring. Checking mental status every 15 minutes (choice B) is not the priority as maintaining the temperature is crucial. Avoiding sedative medications (choice C) may be necessary to accurately assess the patient's neurological status. Rewarming if the temperature is <91�F (32.8�C) (choice D) is incorrect as the goal is to maintain hypothermia for a specific duration before gradual rewarming.

Question 3 of 5

After a change-of-shift report on a ventilator weaning unit, which patient should the nurse assess first?

Correct Answer: D

Rationale: The correct answer is D - Patient who was successfully weaned and extubated 4 hours ago and now has no urine output for the last 6 hours. This patient should be assessed first because the absence of urine output for 6 hours after being extubated could indicate acute kidney injury or other serious complications that need immediate attention. Urine output is a crucial indicator of renal function and can reflect the patient's overall hemodynamic status. In contrast, the other choices do not present immediate life-threatening conditions. Choice A involves a patient in rest mode post-failed breathing trial, which does not require immediate assessment. Choice B mentions continuous PETCO2 monitoring, which is important but not as urgent as assessing a patient with no urine output. Choice C describes a patient with a ScvO2 of 69%, which may need monitoring but does not indicate an urgent priority compared to assessing a patient with no urine output after recent extubation.

Question 4 of 5

When planning the response to the potential use of smallpox as an agent of terrorism, the emergency department (ED) nurse manager will plan to obtain adequate quantities of:

Correct Answer: A

Rationale: The correct answer is A: Vaccine. Smallpox is a contagious and potentially deadly disease caused by the variola virus. The smallpox vaccine is the most effective way to prevent and control the spread of smallpox. By obtaining adequate quantities of the smallpox vaccine, the ED nurse manager can protect healthcare workers and the public from contracting the virus in case of a smallpox bioterrorism event. Atropine (B) is used to treat certain types of nerve agent poisoning, not smallpox. Antibiotics (C) are ineffective against viruses like smallpox. Whole blood (D) is not specifically needed for smallpox treatment.

Question 5 of 5

Which statement about family assessment is false?

Correct Answer: A

Rationale: The correct answer is A because assessing the structure of the family (who comprises the family) is not the last step in family assessment. The rationale is that understanding the family structure is essential at the beginning of the assessment process to identify key relationships and support systems. Assessing interaction among family members helps to understand dynamics and relationships within the family. Assessing communication is crucial to identify roles and patterns of interaction. Ongoing assessment is necessary as family dynamics can evolve throughout the illness. Therefore, A is false as family structure assessment is an important initial step, not the last step.
