A nurse is preparing to infuse a 250-mL unit of packed red blood cells (RBCs) over 2 hours.
The drop factor of the manual intravenous (IV) tubing is 15 drops/mL. How many drops per minute should the nurse adjust the flow rate to deliver?
The Correct Answer is ["31"]
Step 1: Calculate the total volume to be infused. Total volume = 250 mL.
Step 2: Calculate the total time for the infusion in minutes. Total time = 2 hours × 60 minutes/hour = 120 minutes.
Step 3: Calculate the flow rate in mL/min. Flow rate = Total volume ÷ Total time = 250 mL ÷ 120 min = 2.08 mL/min.
Step 4: Calculate the flow rate in drops/min. Flow rate = 2.08 mL/min × 15 drops/mL = 31.25 drops/min. So, the nurse should adjust the flow rate to deliver approximately 31 drops per minute.

Correct Answer is AANDD
Explanation
Choice A rationale
An ileostomy involves creating a stoma, or opening, in the abdominal wall. The location of the stoma is typically in the right lower abdomen.
Choice B rationale
The end of the stoma should not be painful after the procedure. If the patient experiences pain, it could indicate a complication and should be reported to the healthcare provider.
Choice C rationale
The patient should not expect the stoma to be a purple color. A healthy stoma should be red or pink. A purple stoma could indicate a lack of blood flow, which is a serious issue that needs immediate medical attention.
Choice D rationale
After an ileostomy, the patient will have liquid or semi-liquid stool pass through the stoma. This is because the large intestine, which normally absorbs water and forms solid stool, is bypassed or removed in the procedure.
Correct Answer is B

Visual aids can be very helpful for patients with impaired speech. They can use pictures, written words, or devices to help express their thoughts2324.
Choice B rationale
Allowing extra time to communicate with the patient is crucial. It can reduce frustration and improve the effectiveness of communication2324.
Choice C rationale
Completing sentences for the patient can be disrespectful and may not accurately convey the patient’s thoughts2324.
Choice D rationale
Asking open-ended questions can be challenging for a person with impaired speech. It’s better to ask yes/no questions or use other communication strategies2324.
