Mrs. Tan is scheduled to undergo percutaneous transluminal coronary angioplasty (PTCA). Which of the following is the priority goal for her immediately after the procedure?

Correct Answer: B

Rationale: Maintaining blood pressure control is the priority goal for Mrs. Tan immediately after percutaneous transluminal coronary angioplasty (PTCA). PTCA is a procedure used to open narrowed or blocked arteries in the heart. After the procedure, there is a risk of abrupt changes in blood pressure due to various factors, such as contrast dye used during the procedure, stress on the heart, and potential complications. Maintaining stable blood pressure is crucial to ensure adequate perfusion to the heart and other organs. Monitoring and controlling blood pressure help prevent further complications and promote a smooth recovery process for the patient. It is important to address this priority goal to optimize Mrs. Tan's post-procedure outcomes.

Correct Answer: D

Rationale: The most common cause of hyperaldosteronism is an adrenal adenoma, which is a benign tumor of the adrenal gland. Adrenal adenomas produce excessive amounts of aldosterone, a hormone that regulates sodium and potassium balance in the body. This overproduction of aldosterone can lead to increased sodium retention and potassium excretion, resulting in hypertension and low potassium levels in the blood. Excessive sodium intake and deficient potassium intake are not common causes of hyperaldosteronism. Pituitary adenomas are associated with conditions such as Cushing's syndrome or acromegaly, but not hyperaldosteronism.

Correct Answer: A

Rationale: The adrenal cortex is the outer portion of the adrenal glands and is responsible for producing hormones known as corticosteroids. Within the corticosteroids, the adrenal cortex produces glucocorticoids (such as cortisol) which are involved in regulating metabolism and the immune response. Additionally, the adrenal cortex produces androgens which are male sex hormones, although they are present in both males and females. Therefore, the correct substances produced by the adrenal cortex are glucocorticoids and androgens (Choice A).

Correct Answer: D

Rationale: Crying whenever diabetes is mentioned indicates a maladaptive coping mechanism, which can be a sign of ineffective individual coping related to diabetes mellitus. Coping with a chronic condition like diabetes can be overwhelming, and excessive emotional distress may hinder the client's ability to effectively manage their disease. It is important for the nurse to identify maladaptive coping strategies in order to provide appropriate interventions and support for the client.

Correct Answer: C

Rationale: Multiple sclerosis (MS) is a disease that primarily affects the central nervous system (CNS) by causing inflammation, damage, and scarring in the myelin sheath that covers nerve fibers. The optic nerve and chiasm are common areas affected by MS, leading to symptoms such as blurred or double vision, loss of color vision, and pain with eye movement. This involvement is known as optic neuritis, a common early symptom of MS. While MS can affect various parts of the CNS, the optic nerve and chiasm are among the most frequently involved areas, making choice C the correct answer in this case.
