Critical Care Nursing Questions

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, the 21-year-old with a C4 fracture and quadriplegia. This patient is likely to benefit most from patient-controlled analgesia (PCA) due to the inability to self-administer traditional pain medications. With quadriplegia, the patient may have limited mobility and sensation, making it challenging to communicate pain levels effectively. PCA allows the patient to control their pain relief within preset limits, enhancing autonomy and optimizing pain management. Summary: - Choice B: The 45-year-old with femur fracture and closed head injury may benefit from PCA, but the severity of the head injury could affect their ability to use the device effectively. - Choice C: The 59-year-old postoperative elective bariatric surgery patient can typically manage pain with traditional methods postoperatively. - Choice D: The 70-year-old postoperative cardiac surgery patient with mild dementia may have the cognitive ability to use PCA but could potentially benefit more from other pain management strategies due

Correct Answer: A

Rationale: The correct answer is A because the patient is a 36-year-old with a Glasgow Coma Scale score of 3 and no activity on electroencephalogram, indicating severe brain injury and likely irreversible neurological damage. This patient meets the criteria for potential organ donation as they are neurologically devastated. Choice B is incorrect because the patient's condition is related to stroke and atrial fibrillation, not severe brain injury that would make them a candidate for organ donation. Choice C is incorrect because although the patient has a brain injury and a lower Glasgow Coma Scale score, the history of a reversible cause (ovarian cancer metastasis) and a higher GCS score compared to choice A make this patient less suitable for organ donation evaluation. Choice D is incorrect as the patient's diabetic and cardiovascular history does not suggest severe brain injury that would qualify for organ donation.

Correct Answer: A

Rationale: The correct answer is A: a diet of 2500 to 3500 kcal per day. During hemodialysis, the patient loses nutrients and energy, so a high-calorie diet is necessary to maintain proper nutrition and energy levels. 2500-3500 kcal/day is a suitable range for a 100-kg patient. Choice B is incorrect because protein intake should be adequate to prevent malnutrition in hemodialysis patients, typically 1.2g/kg body weight/day. Choice C is incorrect as potassium intake should be restricted in hemodialysis patients due to impaired kidney function. Choice D is incorrect because fluid intake should be individualized based on the patient's fluid status and should not be limited to less than 500 mL per day.

Correct Answer: B

Rationale: The correct answer is B because it acknowledges and validates the patient's belief, showing empathy and support. By stating that the belief gives strength, the nurse facilitates a therapeutic relationship and promotes the patient's emotional well-being. Choice A is incorrect as it challenges the patient's belief system, potentially creating conflict. Choice C is inappropriate as it dismisses the patient's belief and could damage the nurse-patient relationship. Choice D is also incorrect as it invalidates the patient's belief and could harm trust and rapport.
