Nursing Elites

1. 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.

2. Knowing that for a comatose patient hearing is the last sense to be lost, as Judy’s nurse, what should you do?

• A. Tell her family that probably she can’t hear them
• B. Talk loudly so that Wendy can hear you
• C. Tell her family who are in the room not to talk
• D. Speak softly then hold her hands gently

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.

4. A client with anorexia undergoing radiation therapy is being taught by a nurse. Which instruction should the nurse include in the teaching?

• A. Limit high-calorie supplements to between meals
• B. Avoid overeating during your 'good' days
• C. Eat hot foods instead of cold foods
• D. Consume nutrient-dense foods first

Correct answer: D

Rationale: The correct instruction for a client with anorexia undergoing radiation therapy is to consume nutrient-dense foods first. This ensures that the client receives the necessary calories and nutrients. Option A is incorrect because high-calorie supplements should not be limited but rather incorporated wisely into the diet. Option B is incorrect as overeating is not recommended regardless of the type of day. Option C is incorrect as there is no specific preference for hot foods over cold foods in managing anorexia during radiation therapy.

5. A client with gastroesophageal reflux disease is being taught by a nurse about managing the illness. Which of the following recommendations should the nurse include in the teaching?

• A. Limit fluid intake not related to meals.
• B. Chew on mint leaves to relieve indigestion.
• C. Avoid eating within 3 hours of bedtime.
• D. Season foods with black pepper.

Correct answer: C

Rationale: The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.
