HESI Nutrition Practice Exam

Correct Answer: B

Rationale: The correct answer is to obtain a health and dietary history when assessing constipation in elders. This action is crucial as it helps the nurse identify potential causes and contributing factors to constipation in elderly clients. Obtaining a complete blood count (choice A) may be necessary at some point, but it is not the priority in this situation. Referring to a provider for a physical examination (choice C) and measuring height and weight (choice D) are important but are not the priority actions when assessing constipation.

Correct Answer: A

Rationale: The correct answer is to wash hands thoroughly before and after client contact when caring for a client with a salmonella infection. This approach is crucial in preventing the transmission of the infection. While wearing gloves when in contact with body secretions (Choice B), double gloving when in contact with feces or vomitus (Choice C), and wearing gloves when disposing of contaminated linens (Choice D) are important infection control measures, the primary intervention to limit the spread of salmonella is proper hand hygiene.

Correct Answer: D

Rationale: The correct answer is D. A baked potato is high in potassium and helps prevent digitalis toxicity by maintaining adequate potassium levels. While choices A, B, and C all contain some potassium, a baked potato is a more concentrated source of potassium compared to three apricots, a medium banana, or a naval orange. Therefore, the client should choose a baked potato to better meet the dietary needs for preventing digitalis toxicity.

Correct Answer: B

Rationale: When the high-pressure alarm on a ventilator goes off, the nurse's initial action should be to perform a quick assessment of the client's condition. This assessment helps in promptly identifying the cause of the alarm, such as mucus plugging, kinking of the tubing, or other issues. By assessing the client first, the nurse can determine the appropriate intervention needed to address the alarm. Choices A and D are incorrect because disconnecting the client from the ventilator or pressing the alarm reset button should not be the initial actions without assessing the client's condition. While calling the respiratory therapist for help could be beneficial, assessing the client's condition should be the nurse's priority to address the immediate concern.

Correct Answer: B

Rationale: Postoperative arrhythmias are a common and potentially serious complication after cardiac surgery, making them a priority to monitor. Assessing for postoperative arrhythmias takes precedence over other assessments like checking nail beds for color and refill, auscultating for pulmonary congestion, or monitoring peripheral pulses as arrhythmias can have immediate and severe implications for the child's health.
