Correct Answer: B

Rationale: The correct answer is B: Ambulate with assistance. Ambulating helps prevent further bone loss and strengthens muscles, important for osteoporosis patients. Bedrest can worsen bone density loss. Encouraging fluids and providing a high-protein diet are important for overall health but do not directly address the weakness associated with osteoporosis.

Correct Answer: C

Rationale: The correct answer is C: Health promotion. The nurse wrote a diagnosis of Readiness for enhanced urinary elimination, which indicates the patient's willingness to improve their urinary elimination abilities. Health promotion diagnoses focus on improving the client's well-being and enhancing their health potential. In this scenario, the patient's desire to learn self-catheterization aligns with health promotion as it involves empowering the patient to take an active role in their care. Choice A (Risk) is incorrect because the patient is not currently at risk for urinary elimination issues, but rather seeking to enhance their abilities. Choice B (Problem focused) is incorrect as the diagnosis is not about addressing a current problem but rather focusing on potential improvement. Choice D (Collaborative problem) is incorrect as it does not involve collaboration between healthcare providers but rather focuses on the patient's readiness and willingness to enhance their own health outcomes.

Correct Answer: D

Rationale: The correct answer is D: Subclavian veins. Lymph returns to the blood through the subclavian veins because they receive lymphatic drainage from the thoracic duct and right lymphatic duct. Lymphatic vessels merge into lymphatic ducts, which empty into the subclavian veins, allowing lymph to re-enter the bloodstream. The carotid arteries (A) carry oxygen-rich blood to the brain, the aorta (C) is the main artery of the body carrying oxygenated blood from the heart, and the inferior vena cava (B) returns deoxygenated blood from the lower body to the heart. Therefore, choices A, B, and C are incorrect as they are not involved in the return of lymph to the blood.

Correct Answer: C

Rationale: The correct answer is C: Take piroxicam with food or oral antacid. This instruction helps to reduce GI irritation by providing a protective barrier for the stomach lining. Piroxicam is known to cause GI upset due to its effect on prostaglandin synthesis. Taking it with food or an antacid can help minimize this side effect. Choice A (Space the administration every 4 hours) does not address the issue of GI irritation and is not a recommended strategy for preventing this side effect. Choice B (Use the drug for a short time only) is not a direct intervention to prevent GI upset and does not provide guidance on how to manage the side effect when taking the medication. Choice D (Decrease the piroxicam dosage) may not be necessary if the client can manage the side effects with the simple intervention of taking it with food or an antacid.

Correct Answer: C

Rationale: The hallmark of nephritic syndrome is edema due to proteinuria leading to hypoalbuminemia. Protein loss in urine causes decreased colloid osmotic pressure, leading to fluid leaking into tissues, causing edema. Osmotic diuresis (A) is unrelated to nephritic syndrome. Hypolipidemia (B) and hyperproteinemia (D) are not characteristic of nephritic syndrome.
