HESI Nutrition Practice Exam

Correct Answer: B

Rationale: The correct answer is B: 'The tube will remove excess air from your chest.' In a spontaneous pneumothorax, air accumulates in the pleural space, causing lung collapse. The chest tube is inserted to remove this excess air, allowing the lung to re-expand. Choices A, C, and D are incorrect because the primary purpose of a chest tube in pneumothorax is to evacuate air, not fluid, control air entry, or seal a lung hole.

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: C

Rationale: The correct answer is C: 'You will need to drink a bowel preparation solution the day before the test.' Before a colonoscopy, it is essential to cleanse the colon thoroughly by drinking a bowel preparation solution. This helps to ensure that the colon is clear for the procedure, allowing for better visualization and examination of the colon. Choices A, B, and D are incorrect because avoiding eating or drinking after midnight, having a light breakfast, and avoiding medications are not specific instructions related to the colonoscopy preparation process.

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: D

Rationale: The correct answer is D, a preschooler with intermittent alertness. This client may not have the cognitive ability to effectively use a PCA pump due to their age and alertness level. They may not understand how to self-administer the analgesia. Choices A, B, and C are more appropriate candidates for PCA as they are likely to have better comprehension and ability to operate the PCA pump compared to a preschooler with intermittent alertness.
