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
Explanation
Choice A rationale
While observing the patient’s respiratory status is important in all patient care, it is not the priority action in this case. The patient’s decreased level of consciousness and inability to swallow increase the risk of aspiration, which can lead to respiratory complications.
Choice B rationale
Elevating the head of the patient’s bed 30° to 45° is the priority action. A patient who has a decreased level of consciousness and an inability to swallow is at risk for aspiration. Lying down also increases this risk. The priority action by the nurse is to keep the head of the bed elevated to promote gastric emptying and reduce the risk of aspiration.
Choice C rationale
Monitoring intake and output every 8 hours is important for assessing the patient’s hydration status and nutritional needs. However, it is not the priority action in this case. The risk of aspiration due to the patient’s decreased level of consciousness and inability to swallow takes precedence.
Choice D rationale
Checking residual volume every 4 to 6 hours is a standard practice when administering continuous enteral feedings through a gastrostomy tube. It helps to ensure that the patient is tolerating the feedings and not at risk for aspiration due to high gastric residuals. However, in this case, the priority is to prevent aspiration by elevating the head of the bed.
