Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct Answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

For an incontinent elderly client who frequently wets his bed and develops redness and skin excoriation at the perianal area, what is the best nursing goal?
- A. Ensure that the bed linen is always dry
- B. Frequently check the bed for wetness and keep it dry
- C. Place a rubber sheet under the client's buttocks
- D. Keep the patient clean and dry
Correct Answer: A
Rationale: The best nursing goal for an incontinent elderly client with skin excoriation is to ensure that the bed linen is always dry. This helps in preventing further skin breakdown and promoting skin integrity. Choice B, to frequently check the bed for wetness and keep it dry, may not address the issue of prevention if the linen is not consistently dry. Choice C, placing a rubber sheet under the client's buttocks, focuses more on protecting the mattress rather than addressing the client's skin condition directly. Choice D, keeping the patient clean and dry, is important but does not specifically address the preventive aspect of maintaining dry bed linen.
