Correct Answer: D

Rationale: Addison's disease is a rare endocrine disorder characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production. The symptoms of Addison's disease include fatigue, weakness, hyperpigmentation of the skin (due to elevated levels of ACTH stimulating melanocytes), and salt craving (due to aldosterone deficiency). Low serum sodium levels and elevated serum potassium levels are also common laboratory findings in Addison's disease, as aldosterone plays a key role in maintaining electrolyte balance. Patients with Addison's disease are at risk of developing an adrenal crisis, which can be life-threatening if not promptly recognized and treated with glucocorticoid and mineralocorticoid replacement therapy.

Correct Answer: C

Rationale: Fowler's position is the correct position to help a patient experiencing breathing difficulty. In Fowler's position, the patient is sitting up at a 45- to 60-degree angle with the legs either straight or bent. This position allows for maximum chest expansion, helping to improve ventilation and oxygenation. It is commonly used to assist patients with respiratory distress, including difficulties with breathing. Placing the patient in Fowler's position can alleviate the feeling of breathlessness and facilitate easier breathing by promoting better lung expansion.

Correct Answer: D

Rationale: Nursing mothers should not wash their nipples with soap and water prior to feeding. Using soap can dry out the skin and potentially lead to irritation or cracking of the nipple, which can increase the risk of mastitis. It is recommended to simply clean the nipples with water, if necessary.

Correct Answer: A

Rationale: In a patient with suspected pulmonary TB, the most appropriate diagnostic test for confirming the diagnosis is the sputum acid-fast bacilli (AFB) smear and culture. This test involves examining sputum samples under the microscope for the presence of acid-fast bacilli, which are characteristic of Mycobacterium tuberculosis, the bacteria that causes TB. Additionally, culturing the sputum allows for the bacteria to grow in a controlled environment, further confirming the diagnosis. In the given scenario, the patient's symptoms (cough, weight loss, night sweats, hemoptysis), along with chest X-ray findings of upper lobe infiltrates and cavitation, are highly suggestive of pulmonary TB. Therefore, performing a sputum AFB smear and culture is crucial for definitive diagnosis and initiation of appropriate treatment. The other options (Tuberculin skin test, Interferon

Correct Answer: A

Rationale: Clients who are taught skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants are learning skills that involve physical movement and coordination. These activities require the integration of mental and physical skills, and they fall under the psychomotor domain of learning. In this domain, individuals develop physical skills and coordination through practice and repetition. The psychomotor domain is one of the three domains of learning, along with the cognitive domain (which involves knowledge and intellectual skills) and the affective domain (which involves emotions, values, and attitudes).
