Critical Care Nursing Questions and Answers PDF

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 paralysis helps facilitate intubation, surgical procedures, and mechanical ventilation. A: Analgesia - Neuromuscular blocking agents do not provide pain relief; they primarily induce muscle paralysis without affecting pain sensation. B: Anticonvulsant - Neuromuscular blocking agents do not prevent or treat seizures; their mechanism of action is not related to controlling convulsions. D: Sedation - Neuromuscular blocking agents do not induce sedation; they specifically target the neuromuscular junction to cause muscle paralysis.

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.

Correct Answer: A

Rationale: The correct answer is A: Assessing the patient's level of pain. In this situation, the patient's tachycardia, hypertension, and increased respiratory rate could be indicative of pain. By assessing the patient's pain level, the nurse can address any discomfort the patient may be experiencing, which could be contributing to these physiological responses. Summary of other choices: B: Decreasing the SIMV rate on the ventilator - This is not the priority intervention as the patient's symptoms are more likely related to pain rather than the ventilator settings. C: Providing sedation as ordered - Sedation is not the priority in this case as the patient has been tolerating the ventilator well without requiring sedation. D: Suctioning the patient again - Since the airway has been recently cleared, suctioning again is not necessary at this point and would not address the underlying cause of the patient's symptoms.

Correct Answer: B

Rationale: Rationale for Correct Answer (B - Brain death determination is required before organs can be retrieved for transplant): 1. Brain death determination is a medical necessity to ensure the organs are viable for transplant. 2. Organs must be retrieved promptly after brain death to maintain their functionality. 3. Brain death criteria ensure that the donor is truly deceased before organ retrieval. Summary of Why Other Choices are Incorrect: A: While discussing organ donation is important, comfort level is not the main factor in organ shortage awareness. C: Donation after cardiac death is ethically acceptable, but it is not directly related to the need for brain death determination. D: Withdrawing life support solely to become an organ donor is ethically questionable and not a necessary step in organ donation.

Correct Answer: A

Rationale: The presence of an endotracheal tube can predispose the client to increased pain and anxiety due to discomfort, difficulty breathing, and potential for aspiration. The tube insertion process itself can be painful and traumatic. Frequent vital sign assessment, monitor alarms, and room temperature are not directly associated with increased pain and anxiety from the endotracheal tube.
