Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B because asking the patient to share his or her internal dialogue can provide direct insight into the patient's thoughts and feelings, allowing the nurse to address specific anxieties. This approach promotes open communication and understanding. Choice A focuses on providing information but may not directly address the patient's feelings. Choice C is unrelated to addressing the patient's anxiety. Choice D addresses pain control, which is important but not directly related to exploring the patient's emotions. Therefore, option B is the most effective strategy for gaining insight into the patient's feelings in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Thirty-degree elevation of the head of the bed. This is the priority nursing intervention for a mechanically ventilated patient following bilateral lung transplantation because it helps optimize ventilation-perfusion matching, reduces the risk of aspiration, and improves oxygenation. Elevating the head of the bed also decreases the risk of ventilator-associated pneumonia. B: Endotracheal suctioning as needed is important but not the priority intervention in this case. C: Frequent side to side repositioning is important for preventing pressure ulcers but is not the priority for a ventilated patient post-lung transplant. D: Sequential compression stockings are used for preventing deep vein thrombosis, which is important but not the priority in this scenario.

Correct Answer: B

Rationale: Step 1: Start with Background - statement B provides relevant background information about the patient's current condition and why there is a need for communication. Step 2: Move on to Situation - statement D sets the current situation where the nurse expresses concern about the patient's symptom. Step 3: Next is Assessment - statement C details the nurse's assessment findings, highlighting the critical aspects of the patient's condition. Step 4: End with Recommendation - statement A suggests the necessary action to be taken based on the assessment findings. This order ensures a clear and structured communication process. Summary: - Choice A is incorrect as the recommendation should come after providing background, situation, and assessment. - Choice C is incorrect as assessment details should precede the patient's critical condition. - Choice D is incorrect as the situation should be explained before expressing concern.

Correct Answer: B

Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.

Correct Answer: B

Rationale: The correct answer is B: She is in the exhaustion stage of the general adaptation syndrome to stress. Rationale: 1. In the exhaustion stage, the body's resources are depleted due to prolonged stress, leading to fatigue and reduced ability to cope. 2. The elderly woman is likely experiencing high levels of stress due to her granddaughter's critical condition. 3. Managing toddlers while dealing with the emotional distress of a loved one in the ICU can be overwhelming, causing exhaustion. 4. This explanation aligns with the symptoms of fatigue and difficulty managing the children observed by the nurse. Summary: A: Incorrect. Senility is a cognitive condition unrelated to the stress of the situation. C: Incorrect. Assuming a caregiver role can be stressful, but it does not explain the observed exhaustion. D: Incorrect. Macular degeneration affects vision, not the ability to manage stress and children.
