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 A
Explanation
Choice A reason:
When suctioning a tracheostomy tube, it's important to limit the suctioning time to 3 to 4 seconds to avoid hypoxia and trauma to the airway.
Choice B reason:
Sterile technique, not clean technique, is used when performing tracheostomy suctioning to prevent infection.
Choice C reason:
The catheter should be sized appropriately for the tracheostomy tube, but it should not fit too snugly to avoid causing trauma to the airway.
Choice D reason:
Instilling saline prior to suctioning is not recommended as it can lead to complications, including aspiration and increased risk of infection.
Correct Answer is C
Explanation
Choice A reason:
Improved feedings can be a positive sign, but it may not directly indicate the therapeutic effect of phenobarbital.
Choice B reason:
Restored surfactant is not directly related to the action of phenobarbital, which is used to manage symptoms of neonatal abstinence syndrome.
Choice C reason:
Phenobarbital is a medication that can help alleviate CNS irritability in infants with neonatal abstinence syndrome. Therefore, a decrease in CNS irritability indicates a therapeutic effect of the medication.
Choice D reason:
Decreased excoriation is not a primary effect of phenobarbital. This medication primarily addresses CNS symptoms associated with neonatal abstinence syndrome.
