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. When assessing older adult clients for malnutrition at an adult day care center, which risk factors should the nurse consider?

• A. Dental problems
• B. Depression
• C. Both A and B
• D. Ability to prepare meals

Correct answer: C

Rationale: The correct answer is C: Both A and B. Dental problems and depression are both significant risk factors for malnutrition in older adults. Dental problems can lead to difficulty in chewing and swallowing, resulting in reduced food intake. On the other hand, depression can cause changes in appetite and decreased interest in eating, which can also contribute to malnutrition. Although the ability to prepare meals is important, it is not specifically identified as a risk factor for malnutrition within the context of this question. Therefore, choices A and B are the most appropriate answers.

3. A nurse is assessing the nutritional status of an infant who is 6 months old. The infant weighed 2.7 kg at birth. Which of the following indicates to the nurse that the infant is within the expected range?

• A. 5.5 kg
• B. 6.4 kg
• C. 4.5 kg
• D. 3.6 kg

Correct answer: B

Rationale: The correct answer is B, 6.4 kg. An infant's weight should approximately double by 6 months. In this case, starting from a birth weight of 2.7 kg, a weight of 6.4 kg at 6 months indicates normal growth. Choice A (5.5 kg) is below the expected range for a 6-month-old infant. Choices C (4.5 kg) and D (3.6 kg) are also below the expected weight gain, indicating inadequate growth.

4. What symptom would most likely be associated with late dumping syndrome?

• A. abdominal cramps
• B. nausea
• C. diarrhea
• D. confusion

Correct answer: D

Rationale: Confusion is the most likely symptom associated with late dumping syndrome. Late dumping syndrome occurs when blood sugar levels drop rapidly after eating due to rapid gastric emptying. While abdominal cramps, nausea, and diarrhea can occur with dumping syndrome, confusion is specifically linked to late dumping syndrome due to hypoglycemia.

5. The PACU nurse will maintain postoperative T and A client in what position?

• A. Supine with neck hyperextended and supported with pillow
• B. Prone with the head on pillow and turned to the side
• C. Semi-fowler’s with neck flexed
• D. Reverse trendelenburg with extended neck

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.
