Correct Answer: D

Rationale: When caring for an unconscious patient, it is crucial to prevent choking and aspiration. Suctioning the oral cavity helps in removing secretions and preventing potential harm. Moisten the mouth using lemon-glycerin sponges may not effectively clear secretions. Holding the patient's mouth open with gloved fingers can cause discomfort and potential harm. Using foam swabs to remove plaque may not address the immediate risk of aspiration.

Correct Answer: A

Rationale: Erythema on pressure points indicates potential skin breakdown due to prolonged immobility. It requires immediate intervention to prevent pressure ulcers. Lower-extremity pulse strength of 2+ is a normal finding, indicating adequate peripheral perfusion. Fluid intake of 3,000 mL per day is within the normal range and promotes hydration. A bowel movement every other day is a reasonable frequency for some individuals and does not necessarily indicate a need for immediate intervention in this scenario.

Correct Answer: B

Rationale: When a nurse asks a client to identify a number traced on the palm of the hand with their eyes closed, it assesses the client's ability to perceive touch sensations. This test specifically evaluates the tactile discrimination of the client. The other options do not test the client's ability to identify sensations accurately with eyes closed. Option A tests auditory perception, option C tests vibratory sense, and option D tests object recognition but not tactile discrimination, making them incorrect choices.

Correct Answer: C

Rationale: At 0100 on the client's second postoperative night, the nurse should address the client's inability to sleep. Providing a prescribed PRN sedative-hypnotic is appropriate in this situation to help the client rest. Choice A is incorrect because leaving the room and closing the door does not directly address the client's sleep concern. Choice B is not the priority at this moment since the client's main issue is insomnia, not pain. Choice D, while encouraging a non-stimulating activity, does not provide immediate relief for the client's sleeplessness as a sedative-hypnotic would.
