Correct Answer: B

Rationale: Thrombophlebitis is a contraindication for the use of combination oral contraceptives due to the increased risk of thromboembolic events such as deep vein thrombosis and pulmonary embolism. Hyperthyroidism, diverticulosis, and hypocalcemia are not typically contraindications for using combination oral contraceptives, making choices A, C, and D incorrect.

Correct Answer: C

Rationale: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

Correct Answer: C

Rationale: The correct answer is C. Pain in the right shoulder after a cholecystectomy is common due to residual gas from the procedure. Choices A, B, and D are incorrect. It is important to avoid heavy lifting for a longer period than just 1 week to prevent complications. Resuming usual activities after 2 weeks may not be appropriate depending on the individual's recovery. Following a low-protein diet is not a standard recommendation post-cholecystectomy.

Correct Answer: C

Rationale: The correct answer is C. Spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium and excrete sodium and water. Therefore, clients on spironolactone should reduce their intake of foods high in potassium to prevent hyperkalemia. Choices A, B, and D are incorrect because limiting spinach intake due to warfarin, eating anchovies with gout, and taking calcium carbonate with water for osteoporosis do not directly relate to the medication's side effects or dietary restrictions associated with spironolactone.

Correct Answer: A

Rationale: The correct answer is to develop a safety plan with the client. In cases of intimate partner violence, the priority is to ensure the client's immediate safety. While referring the client to a community support group (choice B) and determining if the client has any injuries (choice C) are important interventions, ensuring the client's safety through a safety plan takes precedence. Contacting the client's family about the incident (choice D) may not be appropriate as it can further endanger the client.
