A nurse is preparing to administer three medications to a child who is receiving continuous enteral feedings via a gastrostomy tube. Which of the following actions should the nurse take?
Flush the gastrostomy tube with 10 mL of formula between each medication.
Dilute viscous medications with water.
Add the medications to the bag of formula.
Combine the medications together in one syringe.
The Correct Answer is B
A. Flushing the gastrostomy tube with 10 mL of formula between each medication is incorrect. The nurse should flush the tube with sterile water, not formula, to prevent interactions between the medication and formula, which could cause clogging or reduced medication effectiveness.
B. Diluting viscous medications with water is correct. Thick or viscous medications should be diluted with water to facilitate easier administration through the gastrostomy tube and prevent clogging. This ensures proper delivery of the medication to the gastrointestinal tract.
C. Adding the medications to the bag of formula is incorrect. Medications should never be mixed directly into enteral feeding formula, as they may cause interactions, alter medication absorption, or clog the feeding tube. Each medication should be administered separately.
D. Combining the medications together in one syringe is incorrect. Medications should be administered separately to avoid potential drug interactions, altered medication absorption, and tube blockage. Each medication should be given individually, followed by flushing with water.

Correct Answer is B
Explanation
A. Blood cultures are typically used to detect systemic infections or bacteremia, not Clostridium difficile, which is a bacterial infection primarily affecting the intestines.
B. A stool specimen for culture is the appropriate diagnostic test when C. difficile is suspected, as it can confirm the presence of the bacteria responsible for the infection. The stool test detects toxins A and B, which are produced by C. difficile and cause severe diarrhea.
C. The term "C. diff test" is too vague and does not specify a standard laboratory procedure. The correct test involves stool culture or toxin detection.
D. A stool test for occult blood checks for hidden blood in the stool, which may indicate gastrointestinal bleeding but does not diagnose C. difficile.
Correct Answer is D
Explanation
A. Applying cushioning to the edge of the cast using adhesive tape is incorrect. While padding the edges of the cast can prevent skin irritation, it is not the priority in the first few hours after application. Circulatory status must be assessed first.
B. Using a fan to circulate air around the cast is incorrect. Although plaster casts generate heat as they dry and can be uncomfortable, using a fan is not a priority over assessing circulation and neurovascular function.
C. Repositioning the toddler every 2 hours is important to prevent pressure ulcers and discomfort but is not the immediate priority. Ensuring adequate circulation to the extremities takes precedence.
D. Checking the color and temperature of the toddler's toes is correct. A spica cast can impair circulation, leading to complications such as compartment syndrome. Assessing the color and temperature of the toes helps determine if blood flow is adequate. Pale, cool toes could indicate compromised circulation, requiring immediate intervention.
