A client reports feeling dizzy and light-headed when standing up. What is the nurse's best initial action?

Correct Answer: B

Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.

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: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.

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.
