A client receives a prescription for vancomycin 500 mg IV every 8 hours. The medication is provided in "500 mg per 100 mL of dextrose 5% in water." To administer the medication over an hour, the nurse should set the infusion pump to deliver how many mL/hr? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["100"]

Vancomycin dosage: 500 mg

Concentration of vancomycin solution: 500 mg per 100 mL

Total volume of solution for each dose: 100 mL (since the concentration is 500 mg per 100 mL) To administer 500 mg of vancomycin, we need 100 mL of the solution.

To administer the medication over 1 hour, we need to deliver the entire 100 mL over 1 hour. Therefore, the infusion rate (in mL/hr) would be 100 mL/hr.

Correct Answer is A

Explanation

A. Pyridostigmine is a cholinergic medication that can affect bladder function, and difficulty with urination could indicate a bladder obstruction, which is a contraindication for this medication.
B. Trouble sleeping or insomnia is not typically associated with pyridostigmine use.
C. Unexplained weight loss is not a common side effect of pyridostigmine.
D. Administering pyridostigmine with food or shortly after a meal may help minimize gastrointestinal side effects such as nausea and abdominal discomfort. This however, is not of immediate concern when administering pyridostigmine.

A. Send blood for a complete blood count, electrolytes B. Enalapril 10 mg every morning C. C Ibuprofen 400 mg every 4 to 6 hours PRN for temperature greater than 100.5°F (38° C) D. Admit to the medical floor E. Supplemental oxygen 10 L/min via nasal cannula F. Vital signs every 4 hours G. Continuous pulse oximetry H. Chest x-ray

Correct Answer is ["C","E","H"]

Explanation

A. Send blood for a complete blood count, electrolytes: This is appropriate for assessing the client's overall health status and electrolyte balance, which may be affected by pneumonia and enalapril therapy.

B.Enalapril 10 mg every morning: This is the client's maintenance dose of enalapril for managing hypertension, and it should be continued unless there are specific contraindications or concerns about renal function.

C.Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase blood pressure and interfere with the antihypertensive effects of enalapril. Additionally, NSAIDs can potentially worsen renal function, which may already be compromised in a client with pneumonia.
D.Admit to the medical floor: This is appropriate for a client with pneumonia who may require close monitoring and management of respiratory status and other complications.
E.Supplemental oxygen 10 L/min via nasal cannula: High-flow oxygen can decrease respiratory drive and potentially worsen ventilation-perfusion (V/Q) matching, especially in clients with pneumonia.

F.Vital signs every 4 hours: Regular monitoring of vital signs is essential for assessing the client's response to treatment and identifying any signs of deterioration.

G.Continuous pulse oximetry: Continuous pulse oximetry provides real-time monitoring of oxygen saturation and helps assess the effectiveness of oxygen therapy and the client's respiratory status.

H.While a chest x-ray is often indicated for diagnosing pneumonia, ordering it "now" may not be necessary unless the client's condition is unstable or if there are specific concerns regarding the severity of the pneumonia
