Correct Answer: D

Rationale: The correct answer is D: Eight Cranial Nerve (Vestibulocochlear). This nerve is responsible for hearing and balance. Ringing noises indicate a disturbance in hearing function. The other choices are incorrect because: A: Frontal lobe is associated with executive functions, not hearing. B: Six cranial nerve (abducent) controls eye movement. C: Occipital lobe is related to vision, not hearing. Therefore, the correct choice is D as it directly relates to the symptom described.

Correct Answer: B

Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.

Correct Answer: A

Rationale: The correct answer is A because ranking all the patient's nursing diagnoses in order of priority allows the nurse to address the most critical needs first. By prioritizing based on the urgency and potential impact on the patient's health, the nurse can ensure that interventions are carried out effectively. B is incorrect because priorities may need to be adjusted based on the patient's changing condition. C is incorrect as priorities should consider not only physiological but also psychological and sociological factors. D is incorrect because time is an influencing factor, but it should not be the sole consideration when prioritizing interventions.

Correct Answer: B

Rationale: The correct answer is B: Probenecid (Benemid). Probenecid can increase methotrexate levels, leading to potential toxicity. Methotrexate is primarily eliminated by the kidneys, and Probenecid inhibits renal tubular secretion, causing methotrexate levels to rise. Digoxin (A), theophylline (C), and famotidine (D) do not have significant interactions with methotrexate. In summary, Probenecid is the correct answer as it can increase methotrexate levels through renal tubular secretion inhibition, while the other choices do not have a significant interaction with methotrexate.

Correct Answer: A

Rationale: Correct Answer: A - Apply immobilization device after examination by physician Rationale: 1. Immobilization helps reduce pain and prevent further injury. 2. Physician examination ensures proper diagnosis and treatment plan. 3. Immobilization device may include chest binders or splints for support. 4. It is crucial to follow medical advice to prevent complications. Summary: B: Discouraging deep breaths can lead to respiratory complications. C: Advising against analgesics can increase pain and hinder recovery. D: Increased fluid intake is important but not directly related to rib fracture care.
