When irrigating an open wound with normal saline, it is best to use:
a bulb syringe.
a 20-mL catheter tip syringe.
an IV bag without pressure.
gauze compresses.
The Correct Answer is B
Rationale:
A. A bulb syringe delivers low pressure and is less effective for thoroughly cleansing an open wound, especially if debris is present.
B. A 20-mL catheter tip syringe allows controlled irrigation with sufficient pressure (approximately 8 psi) to effectively remove debris and contaminants without damaging healthy tissue. This is considered the standard method for wound irrigation.
C. Using an IV bag without pressure may not provide adequate force to flush out debris and contaminants.
D. Gauze compresses can clean the wound surface but do not provide the irrigation pressure necessary for thorough cleansing.

Correct Answer is C
Explanation
Rationale:
A. Bowel cleansing may be considered if constipation is contributing, but it is not the standard next step when behavioral strategies alone fail.
B. Urinalysis is useful for ruling out underlying urinary tract infections or diabetes but is typically performed earlier in the evaluation process.
C. A bedwetting alarm is a first-line second-step intervention after behavioral modifications have not produced improvement. It conditions the child to wake in response to bladder fullness and has demonstrated efficacy in reducing nocturnal enuresis.
D. Referral to a pediatric urologist is generally reserved for refractory cases, underlying anatomic abnormalities, or complicated presentations, not as the immediate next step after failed behavioral therapy.
Correct Answer is A
Explanation
Rationale:
A. In a healthy 10-year-old, a heart rate of 60 beats per minute at rest is concerning because the normal resting heart rate for this age group ranges from approximately 70–120 bpm. A heart rate below 70 bpm (bradycardia) may indicate an underlying cardiac conduction issue or other pathology, particularly if symptomatic.
B. 73 bpm is within the normal range for a 10-year-old at rest.
C. 100 bpm is normal and can be expected depending on activity, anxiety, or mild stress.
D. 120 bpm is at the upper limit of normal for a 10-year-old and may be appropriate depending on recent activity or emotional state.
