A client with chronic renal failure is scheduled for hemodialysis in the morning. Which pre-dialysis medication should the nurse withhold until after the dialysis treatment is completed?

Correct Answer: B

Rationale: The correct answer is B: Furosemide (Lasix). Furosemide is a diuretic that promotes fluid loss, and giving it before hemodialysis can lead to excessive fluid loss during the treatment, potentially causing hypovolemia. Withholding furosemide until after the dialysis session helps in preventing this complication. Choices A, C, and D are incorrect because calcium carbonate, spironolactone, and multivitamins are not typically contraindicated before hemodialysis in clients with chronic renal failure.

Correct Answer: D

Rationale: In diabetes insipidus, the body loses excessive amounts of water, leading to diluted urine with low specific gravity. Therefore, when the urine specific gravity is within the normal range, it indicates that the kidneys are properly concentrating urine, which is a sign of effective treatment for diabetes insipidus. Choices A, B, and C are incorrect because in diabetes insipidus, there is polyuria (excessive urination), persistent thirst due to fluid loss, and potential weight loss due to fluid imbalance, so these findings would not indicate effective treatment.

Correct Answer: A

Rationale: The most effective strategy to reduce the incidence of type 2 diabetes in the community is hosting cooking classes on preparing healthy meals. This intervention provides practical skills and education that can directly impact dietary habits, leading to a decreased risk of developing type 2 diabetes. Offering free blood glucose screenings (Choice B) may help in early detection but does not address prevention. Distributing pamphlets on diabetes prevention (Choice C) provides information but lacks the interactive and hands-on approach of cooking classes. Organizing a community walking program (Choice D) promotes physical activity, which is beneficial, but dietary changes have a more significant impact on preventing type 2 diabetes.

Correct Answer: B

Rationale: Recognizing signs of caregiver burnout is the most critical topic to prioritize in the first session. Caregiver burnout can have detrimental effects on both the caregiver and the elderly patient's well-being. By addressing this issue early on, caregivers can learn to identify the signs of burnout, take necessary steps to prevent it, and ensure they can continue providing effective care for their loved ones. Managing medication schedules, effective communication with healthcare providers, and navigating insurance and financial issues are also important aspects to cover in the program. However, recognizing signs of caregiver burnout is essential for the overall health and quality of care provided by the caregivers.

Correct Answer: B

Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.
