HESI Nutrition Exam

Correct Answer: B

Rationale: In this scenario, the nurse should administer acetaminophen as ordered because a slight fever is normal after an MI. This intervention can help manage the fever unless other complications are present. Calling the health care provider immediately is not necessary for a slight fever post-MI. Sending blood, urine, and sputum for culture is not indicated solely based on a slight fever without other symptoms or signs of infection. Increasing fluid intake may be beneficial for various reasons but is not the priority in this situation where managing the fever with acetaminophen is appropriate.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.

Correct Answer: B

Rationale: Dry mucous membranes are a classic sign of dehydration, especially in elderly individuals. Dehydration can lead to decreased moisture in the mucous membranes, making them dry. Skin turgor, although commonly assessed for dehydration in younger individuals, may be less reliable in the elderly due to changes in skin elasticity. Elevated temperature is more indicative of an infection or other conditions. Increased pulse pressure is not typically associated with dehydration in the elderly.

Correct Answer: D

Rationale: The correct sequence for initiating enteral feeding includes verifying tube placement to ensure safety, checking the residual feeding contents to prevent complications, and then administering the feeding. Limiting protein intake is not a step in the sequence for initiating enteral feeding. Protein intake may be adjusted based on the patient's specific nutritional needs, but it is not a part of the immediate sequence for initiating the feeding. Therefore, option D is the correct answer. Options A, B, and C are essential steps to ensure the safe and effective administration of enteral feeding.

Correct Answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.
