HESI Nutrition Practice Exam

Correct Answer: C

Rationale: The correct answer is C: 'Visitors should wash their hands before and after touching the client.' When a client is on contact precautions, it is essential for visitors to practice good hand hygiene to prevent the spread of infection. While wearing a mask and a gown might be necessary for healthcare providers, it is not typically required for visitors. Option B is incorrect because there are indeed special requirements for visitors on contact precautions, including practicing good hand hygiene. Option D is incomplete and does not provide any guidance on infection prevention measures.

Correct Answer: C

Rationale: Inspecting the incision site is a priority in this situation because the redness and swelling indicate a potential infection. This assessment helps the nurse determine the extent of infection and the appropriate intervention, such as administering antibiotics or notifying the healthcare provider. Checking the client's blood pressure (Choice A) may be important but is not the priority in this scenario where signs of infection are present. Assessing the client's pain level (Choice B) is also important but addressing the infection takes precedence. Monitoring the client's respiratory status (Choice D) is essential but not the priority when dealing with a localized infection at the incision site.

Correct Answer: A

Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). When a client is on Coumadin therapy, NSAIDs should be avoided because they can increase the risk of bleeding due to their antiplatelet effects. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not have a significant interaction with Coumadin therapy that would necessitate avoidance.

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.

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.
