Critical Care Nursing Exam Questions Questions

Question 1 of 5

The nurse is caring for a patient who is mechanically ventilated. The nurse understands that what statement should be considered when determining apapbrirob.pcormia/ttees tn ursing interventions?

Correct Answer: A

Rationale: The correct answer is A because communication with intubated patients is often challenging due to the presence of an artificial airway, which hinders speech. This understanding is crucial when determining appropriate nursing interventions to ensure effective patient care. Choice B is incorrect because different patients may require different modes of ventilation based on their specific condition, and controlled ventilation may not always be the preferred mode for all patients. Choice C is incorrect as patients with chronic obstructive pulmonary disease often have difficulty weaning from mechanical ventilation due to their underlying respiratory condition. Choice D is incorrect as wrist restraints are not applied to all patients on mechanical ventilation unless absolutely necessary for safety concerns, such as preventing self-extubation.

Question 2 of 5

A family member tells the nurse, 'I don�t know how I�m going to manage without my mother. She took care of everything for us.' Which response by the nurse is most appropriate?

Correct Answer: A

Rationale: The correct answer is A because it acknowledges the family member's feelings while offering support and resources for managing the situation gradually. By providing resources, the nurse empowers the family member to learn how to handle things independently over time. This approach promotes self-reliance and resilience. Choice B focuses on time rather than active coping strategies, which may not address the family member's immediate needs. Choice C suggests shifting responsibilities to another family member without considering the emotional impact. Choice D jumps to the conclusion of needing professional counseling without exploring other potential solutions or support systems.

Question 3 of 5

The central venous oxygen saturation (ScvO2) is decreasing in a patient who has severe pancreatitis. To determine the possible cause of the decreased ScvO2, the nurse assesses the patient�s:

Correct Answer: B

Rationale: The correct answer is B: Temperature. Decreased ScvO2 in severe pancreatitis can be due to systemic inflammatory response leading to increased metabolic demand and decreased tissue oxygen delivery. Monitoring temperature helps assess for presence of infection or sepsis, which can further decrease tissue oxygenation. Lipase (A) is specific for pancreatitis diagnosis, not directly related to ScvO2. Urinary output (C) is important for assessing renal function, not directly related to ScvO2. Body mass index (D) does not provide information on tissue oxygenation status in this context.

Question 4 of 5

A critically ill patient who is intubated and agitated is restrained with soft wrist restraints. Based on research findings, what is the best nursing action?

Correct Answer: D

Rationale: The correct answer is D: Assess and intervene for causes of agitation. In a critically ill patient, agitation while intubated could indicate underlying issues like pain, delirium, or inadequate sedation. By assessing and addressing the root cause of agitation, the nurse can improve patient comfort and prevent potential harm from restraints. Removing restraints periodically for skin integrity (B) and range of motion (C) is important but should not be the primary focus when agitation is present. Maintaining restraints (A) without addressing the agitation could lead to increased distress and potential complications.

Question 5 of 5

The constant noise of a ventilator, monitor alarms, and inf usion pumps predisposes the patient to what form of stress?

Correct Answer: D

Rationale: The correct answer is D: Sensory overload. Constant noise from medical equipment can overwhelm the patient's senses, leading to sensory overload. This can result in increased stress levels, difficulty concentrating, and overall discomfort. Anxiety (A) is related to worry and fear, but in this context, the primary stressor is sensory overload, not anxiety. Pain (B) is a physical sensation, not directly related to the sensory overload caused by noise. Powerlessness (C) refers to a lack of control or influence, which is not the primary form of stress induced by constant noise. Therefore, the correct choice is D as it directly correlates with the impact of the noise on the patient's sensory perception.
