Correct Answer: B

Rationale: The correct answer is B. Stress, like having three final examinations on the same day, can lead to increased peristalsis due to the activation of the sympathetic nervous system. This can result in faster movement of food through the digestive system. The other choices are incorrect because: A - Ignoring the urge to defecate does not directly relate to increased peristalsis. C - Major depressive disorder is more likely to be associated with decreased peristalsis due to the effects of stress on the body. D - Elderly individuals tend to have reduced peristalsis due to age-related changes in the digestive system.

Correct Answer: A

Rationale: The correct answer is A: Blowing up balloons. Blowing up balloons involves the activation of the facial muscles, which helps prevent muscle atrophy in patients with Bell's palsy. This exercise promotes muscle strength and prevents weakness. Deliberately frowning (B), smiling repeatedly (C), and whistling (D) do not specifically target the facial muscles involved in Bell's palsy and may not be as effective in preventing muscle atrophy.

Correct Answer: A

Rationale: The correct answer is A: Test the patient's hearing promptly. This is because before dispensing hearing aids, it is crucial to accurately assess the patient's hearing ability. Testing the patient's hearing promptly allows the healthcare professional to determine the type and degree of hearing loss, which is essential for selecting the appropriate hearing aids. Performing an otoscopy (choice B) may be part of the assessment but does not provide information on hearing ability. Measuring the width of the patient's ear canal (choice C) is not necessary for dispensing hearing aids. Referring the patient to his primary care physician (choice D) may delay the process of obtaining hearing aids and is not directly related to the responsibility of the health professional dispensing hearing aids.

Correct Answer: D

Rationale: The correct answer is D: Assess the integrity of the patients oral mucosa regularly. Myelosuppression leads to decreased white blood cells, increasing infection risk. The oral mucosa can be a common site for infections. Regular assessment helps in early detection and intervention. A: Encouraging small meals does not directly address infection risk in myelosuppressed patients. B: Providing skin care is important for overall patient care but does not directly address the leading cause of infection-related death. C: Assisting with hygiene is important but does not specifically target the leading cause of infection-related death in oncology patients.
