20-year old Mr. Ang fell off from his horse, and sustained a lft hip fracture. Buck's extension traction is applied. The following statements are true about Buck's extension traction except:

Correct Answer: D

Rationale: Buck's extension traction is typically used as a temporary measure in adults to control muscle spasm and pain while awaiting definitive treatment, such as surgery. It is applied by an orthopedic surgeon under aseptic conditions using wires and pins, through which the pulling force is transmitted to the musculoskeletal structures of the patient. However, Buck's extension traction is not used definitively to treat fractures in children; other treatment modalities are often preferred for pediatric fractures.

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: C

Rationale: Performing chest physiotherapy (CPT) at least two hours after meals is important to prevent potential risks such as vomiting and aspiration. This timing allows for better tolerance of the procedure and decreases the likelihood of complications. By waiting at least two hours after meals, the nurse ensures that the patient's stomach is not full, reducing the risk of regurgitation during the chest physiotherapy session. This practice promotes the safety and well-being of the patient while undergoing this treatment.

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).
