A client is newly diagnosed with type 2 diabetes mellitus. The nurse is educating the client about self-monitoring blood glucose (SMBG) and haemoglobin A1C. Which statement by the client indicates teaching has been effective?

Choice A reason: Placing the client in a darkened room may help alleviate symptoms if the headache is related to migraine or sensitivity to light, but it does not address the potential underlying cause of the severe headache and blurred vision in a client with a history of diabetes and hypertension.

Choice B reason: Obtaining a blood pressure reading is the most critical first step. Severe headache and blurred vision can be symptoms of hypertensive crisis, which is a medical emergency that requires immediate attention to prevent complications such as stroke or organ damage. Checking the blood pressure will help determine if the client's symptoms are due to elevated blood pressure.

Choice C reason: Administering an oral analgesic may provide temporary relief for the headache, but it does not address the potential underlying causes of the symptoms. The priority is to assess and manage any potentially life-threatening conditions.

Choice D reason: Performing a finger stick glucose test is important for monitoring blood glucose levels in a client with diabetes. However, in the context of the severe headache and blurred vision, the immediate concern should be to rule out hypertensive crisis by checking the blood pressure first. Blood glucose can be checked after ensuring the client's blood pressure is not critically high.

Choice A reason: Pacing the client's care to provide periods of rest is important for managing fatigue and preventing overexertion. However, it is not the first action the nurse should take in this situation. Monitoring vital signs is crucial to assess the client's current condition and detect any immediate complications.

Choice B reason: Making arrangements for radioactive iodine therapy is a treatment option for hyperthyroidism. However, this is not the first action the nurse should take. The nurse needs to assess the client's condition and stabilize any immediate issues before considering long-term treatment options.

Choice C reason: Administering a beta-adrenergic blocking agent can help manage symptoms such as a racing heartbeat and nervousness. While this may be part of the treatment plan, it is not the first action the nurse should take. Monitoring vital signs is essential to determine the appropriate interventions.

Choice D reason: Monitoring the client's vital signs frequently is the first action the nurse should take. This helps assess the client's current condition, detect any immediate complications, and guide further interventions. It is crucial to ensure the client's stability before implementing other care measures.
