Correct Answer: B

Rationale: The correct answer is B. The client reporting feeling less anxious is a positive indication of effective treatment for a pulmonary embolism. This suggests that the client's condition is improving psychologically. Option A is incorrect because increased density in all lung fields on a chest x-ray may indicate unresolved issues related to the embolism. Option C is incorrect as diminished breath sounds bilaterally suggest a complication or worsening of the condition. Option D is incorrect as ABG results within normal range do not necessarily indicate effective treatment for a pulmonary embolism, as other complications may still be present.

Correct Answer: B

Rationale: Administering morphine for pain relief is crucial for postoperative clients following a cholecystectomy to manage pain effectively. Placing the client in a supine position may not be ideal as it can cause discomfort and hinder breathing. Applying a warm compress to the incision site can increase the risk of infection. Placing a pillow under the client's knees is not a priority intervention compared to pain management.

Correct Answer: B

Rationale: Tingling in the lips and fingers is a classic sign of hypocalcemia, which can occur as a complication following a thyroidectomy due to inadvertent damage to the parathyroid glands that regulate calcium levels. Hypokalemia (Choice A) presents with muscle weakness and cardiac issues, not tingling. Hyponatremia (Choice C) typically manifests with confusion, seizures, and muscle cramps. Hyperglycemia (Choice D) is associated with increased thirst, frequent urination, and fatigue.

Correct Answer: C

Rationale: The correct action for the nurse to take when preparing to administer IV medication to a client with a latex allergy is to administer the medication through a latex-free IV port. This is crucial as it prevents direct contact of the medication with latex, reducing the risk of an allergic reaction. Choice A is incorrect as using latex gloves can still expose the client to latex. Choice B is not the best option since the administration route is not specified, and using a latex-free syringe alone may not be sufficient to prevent exposure. Choice D is not the most appropriate because the IV tubing and ports should also be latex-free to ensure complete avoidance of latex contact.

Correct Answer: C

Rationale: The correct instruction is to take ferrous sulfate with orange juice to increase absorption because the vitamin C content in orange juice enhances iron absorption. Choice A is incorrect because ferrous sulfate should be taken with food to reduce gastrointestinal side effects. Choice B is incorrect because milk can decrease iron absorption. Choice D is incorrect because antacids can reduce the absorption of ferrous sulfate.
