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: 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.

Correct Answer: B

Rationale: Leukopenia should take priority in planning care for a client receiving external beam radiation to the mediastinum for bronchial cancer because it is a serious side effect that increases the risk of infection. Monitoring leukopenia is crucial to prevent complications. Esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, but leukopenia poses a higher risk of life-threatening infections, requiring immediate attention.

Correct Answer: A

Rationale: The most crucial point to reinforce to the patient after a vasectomy is the need for continued contraception until it is confirmed that the ejaculate is sperm-free. Choice A emphasizes this by highlighting the importance of using another form of contraception until the healthcare provider confirms the absence of sperm. This is essential to prevent unintended pregnancies. Choices B, C, and D do not address the key point of ensuring contraception until sperm absence is confirmed and are therefore not as important to reinforce in this scenario.

Correct Answer: C

Rationale: The correct statement for a client who is lactose intolerant is to decrease dairy products since lactose intolerant individuals should avoid dairy to prevent symptoms like bloating, diarrhea, and gas. Increasing fiber (Choice A) or calories (Choice B) is not directly related to lactose intolerance. Decreasing vitamin D (Choice D) is not necessary as lactose intolerance is about the sugar in dairy, not vitamin D.
