Correct Answer: D

Rationale: The priority action for the nurse is to gently lower the client to the floor (Option D). This action is crucial to prevent injury to both the client and the nurse. Lowering the client to the floor should be done when the client is unable to support his own weight, ensuring a safe position to prevent falls. Checking the client's carotid pulse (Option A) is important, but it should be performed after ensuring the client's safety. Encouraging the client to get to the toilet (Option B) is impractical as the client is already falling. Calling for help in a loud voice (Option C) may cause chaos and alarm other clients, making it a less suitable immediate action in this scenario.

Correct Answer: A

Rationale: Obtaining a subjective estimate of the pain experience by asking the client to rate his pain helps the nurse determine which pain medication should be administered and also provides a baseline for evaluating the effectiveness of the medication. Medicating for pain should not be delayed to use it as a sleep medication, so encouraging him to wait until bedtime is incorrect. Option C is judgmental and inappropriate as all clients deserve prompt attention. Option D should be used as an adjunct to pain medication, not instead of medication, so instructing him in deep breathing exercises alone is not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is 'Daily black, sticky stool.' Black sticky stool (melena) is indicative of gastrointestinal bleeding, a serious condition that requires immediate attention from the healthcare provider. Options B and D, 'Daily dark brown stool' and 'Soft light brown stool twice a day,' respectively, represent variations of normal stool characteristics and do not raise immediate concerns about the client's health. Option C, 'Firm brown stool every other day,' suggests constipation, which is of lesser concern and can be managed with interventions.

Correct Answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse should be auscultated when the blood pressure cuff is applied around the thigh. The nurse should intervene when the UAP is auscultating the popliteal pulse with the cuff on the lower leg because this is incorrect placement. Option A, wrapping the cuff around the girth of the leg, ensures an accurate assessment. Option C, placing the client in a prone position, provides the best access to the artery. The systolic pressure in the popliteal artery is typically 10 to 40 mm Hg higher than in the brachial artery, so a systolic reading 20 mm Hg higher than the blood pressure in the client's arm is within the expected range and does not require intervention.

Correct Answer: D

Rationale: When administering medications through a nasogastric tube connected to low intermittent suction, the nurse should first turn off the intermittent suction device. This step is crucial to prevent the medications from being immediately suctioned out before they can be absorbed. Clamping the nasogastric tube is not the initial action because it may cause pressure buildup and lead to complications. Confirming the placement of the tube is important but should not be the first step in this scenario. Using a syringe to instill the medications comes after ensuring the suction is turned off to enable proper administration and absorption of the medications.
