Critical Care Nursing Questions

Correct Answer: C

Rationale: The correct answer is C: multiplied by 0.85. This is because women typically have lower muscle mass compared to men, resulting in lower creatinine production. Therefore, to adjust for this difference, the creatinine clearance for women is multiplied by 0.85. This correction factor helps to more accurately estimate the GFR in women. Choices A and B are incorrect because the creatinine clearance for women is not the same as or greater than that for men due to the physiological differences in muscle mass. Choice D is also incorrect as multiplying by 1.15 would overestimate the GFR in women.

Correct Answer: A

Rationale: The correct answer is A because a cooler right hand may indicate compromised circulation, potentially due to arterial occlusion or clot formation. This could lead to inadequate perfusion and tissue damage. Immediate action is needed to assess and address the cause. Choice B is incorrect because a MAP of 77 mm Hg is within the normal range for most patients and does not require immediate action. Choice C is incorrect as delivering 3 mL of flush solution per hour is an appropriate rate and does not indicate a need for immediate action. Choice D is incorrect as the flush bag and tubing being changed 3 days ago does not necessarily indicate an immediate issue with the arterial line function.

Correct Answer: B

Rationale: The correct answer is B: Acknowledge family emotions. This is a key component of the VALUE strategy as it emphasizes empathy and understanding towards the emotions that family members may be experiencing during a difficult time. By acknowledging their emotions, healthcare providers can build trust and establish a supportive relationship with the family. Choice A is incorrect because the VALUE strategy focuses on treating family members as integral members of the care team, not just as guests. Choice C is incorrect as learning about family structure and function is important but not specifically part of the VALUE strategy. Choice D is incorrect as using a trained interpreter is important for effective communication but is not specific to the VALUE mnemonic.

Correct Answer: C

Rationale: Rationale: C: Providing the patient with 5 minutes of effleurage (gentle massage) and minimizing disruptions is the most helpful intervention. Effleurage can help reduce anxiety and promote relaxation, improving sleep quality. Minimizing disruptions creates a conducive environment for sleep. A: Providing a bath after REM sleep may disrupt the patient's sleep cycle, worsening anxiety. B: Increasing pain medication may not address the root cause of anxiety and could lead to dependency or side effects. D: Monitoring brain waves with polysomnography is an invasive procedure not typically indicated for managing anxiety-related sleep issues.

Correct Answer: A

Rationale: The correct answer is A: Burn units. Burn units were identified as the first critical care units due to the complex and intensive care required by burn patients. These units were established to provide specialized care for burn victims, including wound management, infection control, and fluid resuscitation. Summary: - Burn units were the first critical care units due to the specialized care needed for burn patients. - Coronary care units focus on cardiac conditions, not the first identified critical care units. - Recovery rooms are for post-operative care, not specifically for critical care. - Neonatal intensive care units are specialized for newborns, not the first critical care units.
