A client with chronic kidney disease is receiving hemodialysis. Which assessment finding should the nurse report to the healthcare provider immediately?

Correct Answer: C

Rationale: The correct answer is C. An elevated blood pressure in clients with chronic kidney disease undergoing hemodialysis can indicate fluid overload or poor dialysis efficacy and should be reported immediately. This finding could lead to complications such as heart failure or pulmonary edema. Choices A, B, and D are not as critical in this situation. Decreased urine output may be expected due to the kidney disease, a weight loss of 1 kg is within an acceptable range, and the presence of a bruit over the fistula is a common finding in clients undergoing hemodialysis and does not require immediate reporting.

Correct Answer: B

Rationale: The most important instruction the nurse should provide to a client with COPD receiving home oxygen therapy is not to smoke while using oxygen. Smoking near oxygen can cause a fire or explosion due to the flammable nature of oxygen. Choice A is incorrect because using oxygen at the highest flow rate tolerated without medical supervision can be harmful. Choice C is the correct answer as wearing oxygen during physical activity can increase the risk of oxygen combustion. Choice D is not the most important instruction; while storing oxygen tanks properly is essential, the immediate safety concern is the risk of fire due to smoking near oxygen.

Correct Answer: B

Rationale: When a client presents with a severe headache, the initial action should be to check their blood pressure. This step is crucial as it can help determine if the headache is related to hypertension or other cardiovascular issues. Administering pain relief medication should only be done after assessing the client's vital signs and confirming the cause of the headache. While assessing for associated symptoms like nausea or photophobia is important for a comprehensive evaluation, it should follow checking the blood pressure to address immediate concerns. Offering a quiet environment is indeed beneficial for the client's comfort, but it is not the priority when dealing with a severe headache.

Correct Answer: C

Rationale: The correct answer is to only use insulin pens. This is because insulin pens provide a convenient and accurate way to administer insulin. Rotating injection sites is important to prevent tissue damage and promote consistent insulin absorption, making choice A incorrect. Injecting insulin into the same site can lead to lipodystrophy and is not recommended, making choice B incorrect. Mixing different types of insulin in the same syringe can alter their action profiles and is generally not recommended, making choice D incorrect.
