The healthcare provider prescribes 500 mL intravenous (IV) bolus of 0.9% normal saline to be infused over 30 minutes. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only.)

NPO status is crucial before a surgical procedure, especially when anesthesia will be administered. It helps prevent complications related to aspiration of gastric contents during the procedure. Failure to adhere to the NPO status can lead to serious respiratory problems, such as aspiration pneumonia.

It is important for the nurse to confirm the NPO status with the client to ensure that they have followed the appropriate fasting guidelines. This should be done to ensure the client's safety during the surgery.

While determining when the client last had pain medication, offering assistance to the restroom, and reviewing postoperative instructions are important aspects of preoperative care, confirming NPO status is the most critical nursing action in this particular scenario.

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.
