Correct Answer: C

Rationale: The correct answer is C: Taking a walk outside. Patients with lymphoma have weakened immune systems, making them more susceptible to infections. Walking outside exposes them to various environmental pathogens, increasing the risk of infection. Going to church (A) and cleaning the house (B) can be done in controlled environments, while watching television (D) does not involve exposure to external pathogens like going for a walk outside does. Therefore, taking a walk outside poses the highest risk for infection among the given activities.

Correct Answer: B

Rationale: The correct answer is B: Hives or rashes. In autoimmune disorders, the immune system mistakenly attacks the body's own tissues, leading to various symptoms. Hives or rashes are common manifestations of autoimmune disorders due to the immune response affecting the skin. Other choices are incorrect because hypotension is not typically associated with autoimmune disorders, localized inflammation may be present but is not specific to autoimmune disorders, and cramping and vomiting are not primary signs of autoimmune disorders.

Correct Answer: A

Rationale: The correct answer is A: Preventing infection. With a low WBC count of 3,000/ul, the client is at high risk for infection due to compromised immune function. Priority is to prevent infection by implementing strict infection control measures, such as hand hygiene, sterile techniques, and isolation precautions. Alleviating pain (B) would be important but not the priority in this case. Controlling infection (C) is similar to preventing infection and would be a secondary intervention. Monitoring blood transfusion reactions (D) is not relevant to the client's current lab values.

Correct Answer: D

Rationale: The correct answer is D: Dependent. In this scenario, the nurse is administering pain medication based on a healthcare provider's prescription, which demonstrates a dependent nursing intervention. The nurse is reliant on the provider's order to carry out this action. Collaborative interventions involve working with other healthcare professionals, independent interventions are actions that nurses can initiate without supervision, and interdependent interventions involve mutual goal-setting and decision-making among healthcare team members.

Correct Answer: C

Rationale: The correct answer is C: High fluid intake. Adequate hydration helps prevent calcium from becoming concentrated in the urine, reducing the risk of calcium stone formation. Increased fiber intake (choice A) may help prevent other types of stones but not specifically calcium stones. Increased protein intake (choice B) can actually increase calcium excretion, potentially increasing the risk of calcium stone formation. Zinc intake (choice D) does not directly impact calcium stone formation. In summary, high fluid intake is crucial for preventing the precipitation of calcium renal stones due to its role in diluting urine and preventing calcium concentration.
