Rationale: Prinzmetal angina, also known as variant angina or vasospastic angina, is characterized by chest pain that occurs at rest, often during the night or early morning, and is unrelated to activity or emotional stress. This type of angina is caused by transient coronary artery vasospasm, which leads to a temporary reduction in blood flow to the heart. Patients with Prinzmetal angina may have normal coronary arteries or minimal atherosclerosis. It differs from stable and unstable angina, which are typically triggered by physical or emotional stress. Nonanginal pain refers to chest discomfort that is not related to cardiac causes.

Correct Answer: C

Rationale: When preparing a discharge diet teaching for a patient with diverticulosis, the nurse should advise the patient to refrain from eating foods with small seeds, such as raspberries. These small seeds can potentially get stuck in the diverticula (small pouches formed in the colon) and lead to inflammation or infection, causing further complications for the patient with diverticulosis. It is important for patients with diverticulosis to consume a low-fiber diet to prevent aggravating the condition. Therefore, avoiding foods like raspberries with tiny seeds is advisable to help manage diverticulosis effectively.

Correct Answer: D

Rationale: An Unna boot is a type of compression bandage that is impregnated with zinc oxide paste. This paste helps to provide a moist environment for the wound, which can promote healing and also has antimicrobial properties. The compression from the Unna boot helps to reduce swelling and improve circulation in the affected area, which is beneficial for treating stasis ulcers. By understanding that an Unna boot contains zinc oxide paste, the home care nurse can ensure proper application and effectiveness in promoting wound healing.

Correct Answer: B

Rationale: Ineffective Protection is a nursing diagnosis that involves a compromised ability to guard against health threats. Patients with systemic lupus erythematosus are prone to skin rashes, lesions, and photosensitivity due to the autoimmune nature of the disease. Providing appropriate skincare is essential in managing the skin manifestations of lupus, such as using gentle cleansers, moisturizers, and sunscreen to protect the skin from further damage. Proper skincare can help maintain skin integrity and prevent infections, which are crucial aspects of protecting patients with systemic lupus erythematosus. While monitoring laboratory findings, practicing careful hand hygiene, and administering prescribed medications are all important aspects of care for lupus patients, providing appropriate skincare directly addresses the Ineffective Protection diagnosis by focusing on protecting the patient's skin health.

Correct Answer: B

Rationale: Clopidogrel (Plavix) is an antiplatelet medication commonly prescribed during the acute care phase immediately after a stroke. This medication helps prevent blood clots from forming by inhibiting platelets in the blood. It is essential during the acute phase to prevent further blockages in the blood vessels that could lead to more strokes or complications. Once the acute phase is managed, other medications may be incorporated during the recovery, stroke prevention, and rehabilitation stages depending on the individual's condition and risk factors.
