Correct Answer: B

Rationale: The correct action for the nurse to take when assisting with the insertion of a nontunneled percutaneous central venous catheter into the subclavian vein is to place the client in Trendelenburg position. This position helps distend the veins and reduces the risk of air embolism during the insertion procedure. Option A, positioning the client in a high-Fowler's position, would not be appropriate as it does not facilitate venous distention. Option C, placing a rolled towel under the client's neck, is not directly related to the procedure and does not serve a specific purpose in this context. Option D, assisting the client into a side-lying position, is also not the correct choice as Trendelenburg position is preferred for this procedure to aid in vein distention.

Correct Answer: B

Rationale: The correct action the nurse should include in the plan of care for a client with Parkinson's disease at risk for aspiration is to instruct the client to tilt their head forward when swallowing. This action helps protect the airway and reduces the risk of aspiration in clients with impaired swallowing, which is common in Parkinson's disease. Encouraging the client to eat thin liquids (Choice A) can increase the risk of aspiration as they are harder to control during swallowing. Giving the client large pieces of food (Choice C) can also increase the risk of choking and aspiration. Having the client lie down after meals (Choice D) can further increase the risk of aspiration due to the potential for reflux. Therefore, the best action to prevent aspiration in this situation is to instruct the client to tilt their head forward when swallowing.

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with multiple sclerosis reporting diplopia is to recommend alternating eye patches during the day. This strategy can help relieve diplopia (double vision) by allowing each eye to rest alternately, reducing eye strain. Encouraging the client to focus on a distant object (Choice A) is not an appropriate intervention for diplopia in this case. Applying a warm compress to the client's eyes (Choice B) and administering artificial tears (Choice D) are not effective interventions for diplopia associated with multiple sclerosis.

Correct Answer: B

Rationale: The correct answer is B. A urine specific gravity of 1.001 is low and indicates dilute urine, which is a sign of fluid overload (hypervolemia). Choice A, serum sodium 138 mEq/L, is within the normal range and does not indicate hypervolemia. Choice C, serum calcium 10 mg/dL, is not typically used to diagnose hypervolemia. Choice D, urine pH 6, is also not a specific indicator of hypervolemia.

Correct Answer: D

Rationale: The correct answer is D: Red, open sores in the mouth. Stomatitis, a common side effect of chemotherapy, presents with red, open sores in the mouth, which can be painful and increase the risk of infection. Choices A, B, and C are incorrect because stomatitis typically does not manifest as dry, cracked lips, bleeding gums, or foul-smelling breath.
