Correct Answer: C

Rationale: Patients with chronic kidney disease are prone to orthostatic hypotension, which can cause dizziness. To prevent this, the nurse should instruct the patient to stand up slowly. Options A, B, and D do not directly address the issue of orthostatic hypotension and dizziness in this scenario.

Correct Answer: C

Rationale: Elevating the affected leg is a crucial intervention in the care of a client with deep vein thrombosis (DVT). This position helps reduce swelling and promotes venous return, which can alleviate symptoms associated with DVT. Applying ice packs (Choice A) may worsen the condition by causing vasoconstriction. Encouraging ambulation (Choice B) can dislodge the clot and lead to fatal complications. Massaging the affected area (Choice D) can also dislodge the clot and is contraindicated in DVT.

Correct Answer: C

Rationale: During triage after a mass casualty event, the client showing signs of hypovolemic shock should be prioritized. Hypovolemic shock is a life-threatening condition that requires immediate attention to restore circulation and prevent death. While clients with head trauma, burns, and fractures also need urgent care, hypovolemic shock poses an immediate threat to life and must be addressed first to stabilize the client's condition.

Correct Answer: B

Rationale: The correct answer is B, Hydromorphone. Hydromorphone is an opioid analgesic commonly used to manage severe pain effectively. In this case, the client's stable respiratory rate of 14/min indicates that it is safe to administer an opioid for pain relief. Promethazine (choice A) is an antiemetic and antihistamine, not the first choice for severe pain management. Ketorolac (choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that may not be potent enough for severe pain relief associated with osteoporosis. Amitriptyline (choice D) is a tricyclic antidepressant, not typically used as a first-line medication for severe pain.

Correct Answer: B

Rationale: The correct answer is B: Cut toenails straight across. This instruction is vital for clients with diabetes as it helps prevent ingrown toenails and infections, reducing the risk of foot ulcers. Applying lotion between the toes (choice A) should be avoided as it can create a moist environment prone to fungal infections. Using a heating pad (choice C) can lead to burns or injuries due to reduced sensation common in diabetes. Soaking feet in warm water daily (choice D) can also increase the risk of skin breakdown and should be avoided.
