A rectal suppository is a medication given to a resident by a nurse for which of the following reasons?

Correct Answer: D

Rationale: The correct answer is D: To treat constipation. A rectal suppository contains medication that helps soften stool and stimulate bowel movements, making it an effective treatment for constipation. It is directly inserted into the rectum to deliver the medication. Choices A, B, and C are incorrect because rectal suppositories are not typically used for reducing fecal incontinence, eliminating bouts of diarrhea, or inducing bowel movements.

Correct Answer: D

Rationale: The correct answer is D: Systole. During systole, the ventricles contract to pump blood out of the heart. This phase is crucial for maintaining blood circulation and providing oxygen to the body. Flatlining (A) refers to a state of no cardiac activity, which is not related to ventricular contraction. Diastole (B) is the phase when the heart relaxes and fills with blood, opposite to ventricular contraction. Homeostasis (C) is the body's ability to maintain internal stability and is not specific to heart function. In summary, systole is the correct choice as it specifically describes the phase of heart function where the ventricles contract to pump blood, while the other options do not accurately describe this process.

Correct Answer: C

Rationale: The correct answer is C because as individuals age, there is a natural decrease in the ability of the lungs to efficiently exchange oxygen and carbon dioxide, leading to a decrease in oxygen levels in the blood. This is due to factors such as decreased lung elasticity, reduced respiratory muscle strength, and changes in lung structure. Explanation for other choices: A: Air sacs do not increase in the lungs with age, rather they may lose elasticity. B: Chest muscles tend to weaken with age, not strengthen. D: Lung capacity typically decreases with age due to changes in lung function and structure, not increases.

Correct Answer: D

Rationale: The correct answer is D: Burnout. Burnout is the result of prolonged stress and frustration, leading to mental and physical exhaustion. It specifically occurs in response to chronic work-related stress. Agitation (A) refers to a state of anxiety or nervousness. Social anxiety disorder (B) is a mental health condition characterized by intense fear of social situations. Sundowning (C) is a phenomenon associated with confusion and agitation in the late afternoon or evening, commonly seen in individuals with dementia. Therefore, only burnout accurately describes the condition of mental or physical exhaustion due to prolonged stress and frustration.

Correct Answer: A

Rationale: The correct answer is A: Biopsy. A biopsy involves the removal of a sample of tissue for diagnostic purposes. It is commonly used to detect cancer or other diseases. Arthroscopy (B) is a minimally invasive surgical procedure to visualize, diagnose, and treat problems inside a joint. Telemetry (C) is the automatic measurement and transmission of data from remote sources. Bronchoscopy (D) is a procedure to examine the airways in the lungs. Only biopsy directly involves the removal of tissue for diagnosis.
