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: 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: D

Rationale: The most appropriate meal plan for a client following a myocardial infarction and placed on a sodium-restricted diet should include fresh ingredients with low sodium content to promote heart health. Option D, which consists of 3 oz. turkey, 1 fresh sweet potato, 1/2 cup fresh green beans, milk, and 1 orange, aligns best with these requirements. Option A contains canned beets, which are typically high in sodium. Option B includes canned salmon, which may have added sodium. Option C has a bologna sandwich, which is processed and high in sodium. Therefore, Option D is the most suitable choice for a client needing a low-sodium diet after a heart attack.

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: B

Rationale: The correct answer is B: Sliced turkey sandwich and canned pineapple. This lunch choice is suitable for a client with congestive heart failure as it is low in sodium. Sliced turkey is a lean protein choice, and canned pineapple is a low-sodium fruit option. Choice A contains high-sodium items like cheese and 2% milk. Choice C includes a cheeseburger, which is typically high in sodium, and a baked potato could also be high in sodium depending on preparation. Choice D consists of mushroom pizza and ice cream, both of which can be high in sodium, especially in processed or restaurant-prepared forms.
