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: 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: A

Rationale: The correct answer is to change the TPN tubing and solution every 24 hours to reduce the risk of infection. This practice helps prevent microbial growth and contamination in the TPN solution. Monitoring the infusion rate closely (choice B) is important for preventing metabolic complications but does not directly reduce the risk of infection. Keeping the head of the bed elevated (choice C) is beneficial for preventing aspiration in feeding tube placement but is unrelated to reducing infection risk in TPN. Ensuring the solution is at room temperature before infusing (choice D) is essential for patient comfort and preventing metabolic complications but does not specifically address infection risk reduction.

Correct Answer: B

Rationale: Corrected Hemoglobin and hematocrit levels should be monitored closely after blood transfusions to assess the effectiveness and identify any complications. Monitoring hemoglobin and hematocrit levels helps evaluate the patient's oxygen-carrying capacity and blood volume. While platelets are crucial for clotting, they are not typically affected immediately after a blood transfusion. White blood cell count monitoring is more relevant in assessing infection or immune response, not directly related to a blood transfusion. Bleeding time measures platelet function, which is not the primary concern immediately after a blood transfusion.

Correct Answer: C

Rationale: The correct answer is C. Discarding leftovers after 48 hours is not an effective recommendation to prevent foodborne illnesses. Leftovers should actually be discarded within 2 hours if they have been at room temperature. Choices A, B, and D are all effective strategies to prevent foodborne illnesses: avoiding unpasteurized dairy products reduces the risk of harmful bacteria, keeping cold food temperatures below 4.4�C (40�F) inhibits bacterial growth, and washing raw vegetables thoroughly removes contaminants.
