A client receives a prescription for heparin 900 units/hr IV. The IV bag contains heparin 25,000 units in 500 mL of 0.45% normal saline.
How many mL/hr should the nurse program the infusion pump to deliver?
The Correct Answer is ["18"]
Step 1 is to calculate the infusion rate. The prescription is for heparin 900 units/hr IV. The IV bag contains heparin 25,000 units in 500 mL of 0.45% normal saline.
So, the calculation would be (900 units ÷ 25,000 units) × 500 mL = 18 mL/hr.

Correct Answer is A
Explanation
Choice A rationale
The antibiotic cefdinir is used to treat many different types of infections caused by bacteria. While a balanced diet is important for overall health, yogurt or buttermilk is a better choice due to their probiotic content, which may promote gut health and support the immune system.
Choice B rationale
Green leafy vegetables are rich in vitamins and minerals, but they are not a primary focus for a client with a postoperative wound infection. The emphasis should be on foods that support the immune system and overall recovery, such as yogurt or buttermilk.
Choice C rationale
Avocados and cheese are not specifically recommended for a client with a postoperative wound infection. While these foods are part of a balanced diet, they do not have specific benefits for a person taking cefdinir.
Choice D rationale
Fresh fruits are generally a healthy dietary choice, but they are not particularly relevant to the management of a postoperative wound infection. The emphasis for this client should be on foods that support wound healing and immune function, such as yogurt or buttermilk.
Correct Answer is B
Explanation
Choice A rationale
While advising family members to monitor for symptoms of illness is important, it’s not the most crucial action for the nurse to take immediately after testing the patient for COVID-194.
Choice B rationale
Implementing droplet precautions, placing the patient in a private room, and keeping the door closed is the most crucial action. This helps prevent the potential spread of COVID-19 to other patients and healthcare workers.
Choice C rationale
Informing the patient to notify others about potential exposure is important, but it’s not the most crucial action immediately after testing.
Choice D rationale
Initiating an IV infusion for the administration of an antiviral drug is not the most crucial action. Antiviral medication is typically administered after a positive test result, not before.
