Correct Answer: C

Rationale: Elevating the affected leg promotes venous return and reduces swelling, which is a priority intervention for a client with suspected DVT. This action helps prevent the thrombus from dislodging and causing further complications. Encouraging ambulation may dislodge the clot, leading to a pulmonary embolism. Applying a warm compress can increase blood flow to the area, potentially dislodging the clot. Administering anticoagulants is essential but should not be the first action as elevation helps to reduce the risk of complications associated with DVT.

Correct Answer: D

Rationale: Flushing the PEG tube with water before and after feedings helps prevent clogging and maintains tube patency. Proper flushing is essential for avoiding complications related to tube blockages. Elevating the head of the bed is important for preventing aspiration during and after feedings, not specifically related to PEG tube complications. Aspirating gastric contents before administering medications is not routinely recommended for PEG tube care. Clamping the tube between feedings can lead to tube occlusion and is not a standard practice in PEG tube care.

Correct Answer: B

Rationale: In hyperthyroidism, there is an increase in metabolism, leading to symptoms such as increased appetite, weight loss, and heat intolerance. Therefore, the nurse should expect an increased appetite in a client with hyperthyroidism. Choices A, C, and D are incorrect because decreased heart rate and cold intolerance are more commonly associated with hypothyroidism, while weight gain is not typically seen in hyperthyroidism.

Correct Answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.

Correct Answer: A

Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.
