Correct Answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

Correct Answer: D

Rationale: The correct answer is D because starch, fiber, and sugar are all sources of carbohydrates. Starchy foods like bread, rice, and potatoes contain starch; fruits, vegetables, and whole grains provide fiber; and sugars are found in sweet foods like fruits, honey, and desserts. Fatty acids and amino acids are not sources of carbohydrates, so choices A, B, and C are correct while choices A and B are incorrect.

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.

Correct Answer: C

Rationale: The priority nursing goal for an adolescent with anorexia nervosa is to stop weight loss or restore weight. This is crucial in addressing the immediate health risks associated with anorexia nervosa, such as malnutrition, organ damage, and potential life-threatening complications. While encouraging effective coping skills, restoring normal eating habits, and promoting a realistic self-image are important aspects of treatment, stopping weight loss or restoring weight takes precedence due to the severe physical consequences of anorexia nervosa.

Correct Answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
