Critical Care Nursing Questions

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: D

Rationale: Step 1: Abdominal pain, chills, and elevated temperature suggest a serious complication like visceral perforation. Step 2: Peritoneal dialysate return assessment won't address the potential life-threatening issue. Step 3: Checking blood sugar or evaluating neurological status is not relevant to the presenting symptoms. Step 4: Informing the provider of probable visceral perforation is crucial for prompt intervention and further evaluation.

Correct Answer: A

Rationale: The correct answer is A: Medical futility. In this scenario, the patient's condition is terminal with no treatment options left. Continuing chemotherapy offers no benefit and may even harm the patient. Medical futility refers to interventions that are unlikely to achieve the desired outcome. B: Palliative care focuses on improving quality of life for patients with serious illnesses, which is not being addressed in this case. C: Terminal weaning involves gradually removing life-support measures, which is not happening here. D: Withdrawal of treatment would be appropriate if the treatments were no longer beneficial, but the issue here is the continued provision of futile treatment.

Correct Answer: C

Rationale: The correct answer is C: Paralysis. Neuromuscular blocking agents work by blocking the transmission of nerve impulses at the neuromuscular junction, leading to muscle paralysis. This is essential in ventilated patients to facilitate mechanical ventilation and prevent patient-ventilator dyssynchrony. Rationale: A: Analgesia - Neuromuscular blocking agents do not provide pain relief. They do not have any direct analgesic properties. B: Anticonvulsant - Neuromuscular blocking agents do not prevent or treat seizures. They do not have anticonvulsant effects. D: Sedation - While sedatives may be used in conjunction with neuromuscular blocking agents, the primary mode of action of these agents is muscle paralysis, not sedation.

Correct Answer: A

Rationale: The correct answer is A: Diminished breath sounds over the left lung field. This finding could indicate a pneumothorax, a serious complication of subclavian CVC insertion. Immediate action is required to prevent respiratory distress. Incorrect answers: B: Localized pain at insertion site is common post-procedure and may not indicate a serious issue. C: A central venous pressure of 5 mm Hg is within the normal range and does not require immediate action. D: Slight bloody drainage is expected initially and can be managed with routine care.
