A nurse is caring for a client with a history of hypertension who presents with a severe headache and blurred vision. What is the most likely cause of these symptoms?

Choice A rationale
Administering antihypertensive medication as prescribed is the priority action for a client with a history of hypertension presenting with severe headache, blurred vision, and confusion.
These symptoms suggest a hypertensive crisis, which requires immediate blood pressure reduction to prevent further complications.
Choice B rationale
Preparing the client for a lumbar puncture is not the priority action in this scenario. While a lumbar puncture may be necessary to rule out other conditions, the immediate concern is to manage the hypertensive crisis.
Choice C rationale
Initiating seizure precautions is important if the client is at risk of seizures, but the priority action is to address the hypertensive crisis by administering antihypertensive medication.
Choice D rationale
Monitoring the client’s blood glucose levels is important for overall health management, but it is not the priority action in this scenario. The immediate concern is to manage the hypertensive crisis.

Choice A rationale
Decreased breath sounds in the lower lobes can indicate areas of the lung that are not ventilating well, but this finding alone does not specifically indicate an exacerbation of COPD. It could be due to other conditions such as pleural effusion or atelectasis.
Choice B rationale
Increased respiratory rate and use of accessory muscles are signs of respiratory distress and indicate that the patient is working harder to breathe. These findings are consistent with an exacerbation of COPD, where the airways are more obstructed, and the patient has difficulty maintaining adequate ventilation.
Choice C rationale
Elevated blood pressure and heart rate can occur in many conditions and are not specific indicators of a COPD exacerbation. These vital sign changes can be due to pain, anxiety, or other stressors.
Choice D rationale
Presence of wheezing and cyanosis are also indicators of a COPD exacerbation. Wheezing indicates airway obstruction, and cyanosis indicates hypoxemia, both of which are common during an exacerbation.
