The nurse is caring for a client admitted with an acute exacerbation of chronic obstructive pulmonary disease (COPD) who reports a pounding headache. Which action should the nurse take?

A pounding headache in a client with COPD may be a symptom of increased carbon dioxide (CO2) levels in the blood, known as hypercapnia. Hypercapnia can lead to vasodilation, resulting in headaches. In this situation, it is crucial to assess the client's blood pressure to determine if it is elevated, as this could be contributing to the headache. Obtaining a manual blood pressure measurement allows for a more accurate assessment of the client's blood pressure compared to automated measurements. It is important to assess both systolic and diastolic blood pressures, as elevated blood pressure can worsen headaches and have other negative effects on the client's health. Elevating the head of the bed no higher than 30 degrees is a general measure used to improve respiratory function in clients with COPD. However, in this specific situation, it may not directly address the pounding headache. Elevating the head of the bed can help reduce dyspnea and improve oxygenation, but it may not alleviate the headache caused by hypercapnia. Affirming blood glucose levels are below 160 mg/dL (8.88 mmol/L) is not the primary concern in this case. While high blood glucose levels can have various effects on the body, including headaches, the priority is to assess the client's blood pressure due to the specific context of a COPD exacerbation. Checking for a stat intravenous diuretic prescription is not necessary in response to the client's headache. Diuretics are typically used to remove excess fluid from the body and may not directly address the underlying cause of the headache in this situation.
