Correct Answer: D

Rationale: The correct action for the nurse to implement is to consult with the pharmacist regarding the change in prescription. With the high first-pass effect of the medication when given orally, it reduces its bioavailability, meaning a dosage adjustment may be necessary to achieve the desired therapeutic effect. Continuing to administer the medication via the IV route (choice A) is not appropriate as the prescription has been changed to oral administration. Giving half the prescribed oral dose until consulting the provider (choice B) is not recommended without proper guidance, which should come from consulting with the pharmacist. Simply administering the medication orally as prescribed (choice C) without addressing the potential issue of reduced bioavailability may lead to suboptimal treatment outcomes.

Correct Answer: D

Rationale: The correct intervention for the nurse to implement in this scenario is to apply emollient to the affected area at least twice daily. This is because applying emollients helps address dry skin, which is a common cause of itching in older adults. Explaining the importance of bathing or showering daily (Choice A) may be helpful for general hygiene but may not specifically address the itching. Encouraging fluid intake (Choice B) and keeping the legs covered (Choice C) are not directly related to addressing the itching caused by dry skin.

Correct Answer: A

Rationale: In this scenario, the most appropriate interdisciplinary team member for the nurse to consult is a hospice nurse. Hospice nurses specialize in managing pain and symptom control, which aligns with the client's needs for managing severe chronic pain. While pain specialists (choice B) focus on pain management, in this case, the client specifically requested hospice care for pain management. Consulting a psychologist (choice C) may be beneficial for addressing psychological aspects, but the client's immediate need is pain management. Forming an interdisciplinary team (choice D) is not as specific as consulting a hospice nurse, who has the specialized skills required to address the client's pain effectively.

Correct Answer: C

Rationale: Auscultation of a thrill on the left forearm is the correct observation indicating that the AV fistula is patent. A thrill is a palpable vibration or buzzing sensation felt over the fistula, indicating the presence of blood flow. Choices A, B, and D do not directly assess the patency of the fistula. Distended, tortuous veins in the left hand may indicate venous hypertension; a bounding radial pulse could suggest increased blood flow through an artery, but it does not confirm fistula patency; assessment of a bruit indicates turbulent blood flow, but it does not confirm patency.

Correct Answer: B

Rationale: The correct answer is B: Vastus lateralis muscle. The vastus lateralis muscle is a recommended site for IM injections in adults due to its size and accessibility. The dorsal gluteal muscle is not recommended for IM injections in adults due to the proximity to major nerves and blood vessels, increasing the risk of injury. The rectus femoris muscle is not a common site for IM injections in adults. The deltoid muscle is typically used for IM injections in small-volume medications or vaccines, especially in adults.
