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. Rectal suppositories are commonly used to provide direct medication to the rectum to stimulate a bowel movement in cases of constipation. The suppository dissolves and lubricates the rectum, softening the stool and making it easier to pass. It is not used to reduce fecal incontinence (A), eliminate bouts of diarrhea (B), or induce a bowel movement in general (C). These options do not align with the specific purpose of rectal suppositories in treating constipation.

Correct Answer: D

Rationale: The correct answer is D: Systole. During systole, the ventricles of the heart contract to pump blood out into the circulation. This phase is essential for maintaining blood flow and delivering oxygen and nutrients to the body. A: Flatlining is incorrect as it refers to a complete absence of heart activity, which is a medical emergency. B: Diastole is incorrect as it is the phase when the heart muscle relaxes and fills with blood. C: Homeostasis is incorrect as it refers to the body's ability to maintain internal balance, not a specific phase of heart function.

Correct Answer: C

Rationale: The correct answer is C: Oxygen in the blood decreases. As people age, lung function declines, leading to reduced oxygen intake and exchange in the bloodstream. This is a normal age-related change due to decreased lung elasticity and efficiency. Choice A is incorrect as air sacs typically decrease in number and size with age. Choice B is incorrect because chest muscles tend to weaken, not strengthen, as individuals age. Choice D is also incorrect since lung capacity tends to decrease with age due to changes in lung tissue and decreased respiratory muscle strength.

Correct Answer: D

Rationale: The correct answer is D: Burnout. Burnout is a state of mental and physical exhaustion caused by prolonged stress and frustration. It is typically related to work or caregiving responsibilities. Agitation (A) refers to a state of anxiety or nervousness. Social anxiety disorder (B) is characterized by excessive fear of social situations. Sundowning (C) is a term used to describe the increase in confusion and agitation that occurs in the late afternoon or evening for individuals with dementia. Burnout specifically addresses the concept of exhaustion due to prolonged stress and frustration, making it the most appropriate choice in this context.

Correct Answer: A

Rationale: The correct answer is A: Biopsy. A biopsy involves removing a sample of tissue for analysis and diagnosis. This procedure helps in identifying diseases or conditions. Arthroscopy (B) is a minimally invasive surgical procedure to visualize and treat joint problems. Telemetry (C) is a method of monitoring and transmitting data wirelessly. Bronchoscopy (D) is a procedure to visualize the airways in the lungs, not specifically for tissue sampling. In conclusion, only a biopsy involves tissue removal for diagnostic purposes.
