A nurse is caring for a toddler whose guardian reports multiple episodes of diarrhea. The provider suspects Clostridium difficile. Which of the following actions should the nurse take?
Collect a stool specimen for occult blood.
Conduct a tape test.
Obtain a stool specimen for culture.
Draw a blood culture.
The Correct Answer is C
Choice A reason:
Collecting a stool specimen for occult blood is not the most relevant test for suspected
Clostridium difficile infection. Stool culture or testing for C. difficile toxins is more appropriate.
Choice B reason:
Conducting a tape test is used to diagnose pinworms, not Clostridium difficile infection.
Choice C reason:
This statement is correct. Obtaining a stool specimen for culture, specifically for C. difficile, is the appropriate action for suspected infection.
Choice D reason:
Drawing a blood culture is not the primary diagnostic test for Clostridium difficile. Stool culture or testing for C. difficile toxins is more appropriate.

Correct Answer is B
Explanation
Choice A reason:
Encouraging fruit juices is not the best approach for rehydration in a child with mild dehydration. Fruit juices can be high in sugar and may worsen diarrhea.
Choice B reason:
Giving oral rehydration solution in small, frequent amounts is the recommended treatment for mild dehydration due to infection. This helps replace lost fluids and electrolytes.
Choice C reason:
Promethazine is not indicated for the treatment of dehydration. It is an antihistamine and antiemetic, but it does not address the underlying issue of fluid loss.
Choice D reason:
Offering banana and rice can be part of a bland diet after rehydration, but it does not address the immediate need for replenishing lost fluids and electrolytes. The priority is to start with oral rehydration solution.
Correct Answer is B
Explanation
Choice A reason:
A weight loss of 0.25 kg (0.55 lb) may be within the range of normal fluctuation for an infant and may not necessarily warrant immediate reporting. However, it should be monitored closely.
Choice B reason:
Vomiting twice in 4 hours after receiving digoxin is a concerning finding. Digoxin has a narrow therapeutic range, and vomiting can lead to potential overdose. This should be reported to the provider for further evaluation.
Choice C reason:
A respiratory rate of 30/min may indicate increased work of breathing, which is a concern in an infant with heart failure. However, it is not specific to digoxin administration and may require
intervention but not immediate reporting.
Choice D reason:
A heart rate of 130/min is within the range of normal for an infant, especially one with heart failure. This finding is not specific to digoxin administration and may not warrant immediate reporting.
