Correct Answer: C

Rationale: The correct answer is C because avoiding alcohol before bedtime can help promote better sleep. Choice A is incorrect as vigorous exercise close to bedtime can actually hinder sleep. Choice B is also incorrect as consuming beverages with caffeine or sugar close to bedtime can disrupt sleep. Choice D, while a good practice, does not directly address the issue of avoiding alcohol before bedtime to improve sleep quality.

Correct Answer: B

Rationale: The correct answer is B because chest physiotherapy (CPT) helps reduce respiratory infections by loosening mucus in the lungs. Choice A is incorrect because coughing may temporarily increase during CPT treatments as mucus is being cleared. Choice C is incorrect because postural drainage is typically performed before meals. Choice D is incorrect because while CPT can help manage symptoms and improve lung function in COPD, it does not cure the disease.

Correct Answer: C

Rationale: The correct answer is C. Somatic symptom disorder is characterized by individuals having excessive preoccupation with physical symptoms that may or may not have an identifiable medical cause. Choice A is incorrect because the sudden onset of symptoms due to stress is more indicative of acute stress reaction. Choice B is incorrect as it describes physical manifestations related to known medical conditions, not somatic symptom disorder. Choice D is incorrect as it relates to health anxiety or illness anxiety disorder, where individuals avoid seeking medical care due to fear of receiving a diagnosis.

Correct Answer: C

Rationale: The correct answer is monitoring intake and output and checking for edema. Monitoring intake and output provides information about fluid balance in the body, while checking for edema helps assess for fluid overload. Lung sounds and signs of orthopnea are more indicative of respiratory issues rather than fluid balance. Daily weight measurement is useful to assess fluid status, but it alone may not provide a comprehensive evaluation of fluid balance.

Correct Answer: B

Rationale: The correct answer is B because a decrease in blood pressure is an expected outcome when propranolol, a beta-blocker, is effectively managing hyperthyroidism. Propranolol helps control symptoms such as tachycardia and hypertension associated with hyperthyroidism. Choices A, C, and D are incorrect because weight gain, increased energy, and an increased respiratory rate are not direct indicators of propranolol's effectiveness in treating hyperthyroidism.
