A nurse is teaching the parents of a child who is to start using a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
"The spacer increases the amount of medication delivered to the oropharynx."
"The spacer increases the amount of medication delivered to the lungs."
"Inhale rapidly using the spacer with the MDI."
"Cover exhalation slots of the spacer with lips when inhaling."
The Correct Answer is B
A. This statement is incorrect; the spacer does not primarily increase medication delivery to the oropharynx.
B. The spacer helps to increase the amount of medication that reaches the lungs by allowing larger particles to settle out and preventing them from being deposited in the mouth and throat.
C. Inhaling slowly and deeply is recommended for effective medication delivery when using an MDI with a spacer.
D. Covering the exhalation slots would prevent proper airflow and could cause the child to inhale exhaled air, which is not recommended during inhalation.

Correct Answer is C
Explanation
A. Bradycardia is not typically expected in toddlers with heart failure; instead, tachycardia (increased heart rate) is more common as the body compensates for decreased cardiac output.
B. Weight loss is generally not a typical finding in toddlers with heart failure; rather, they often experience weight gain due to fluid retention.
C. Orthopnea, or difficulty breathing when lying flat, is a common symptom of heart failure and would be expected in a toddler due to fluid overload affecting respiratory function.
D. Increased urine output is usually not expected in heart failure; rather, fluid retention often leads to decreased urine output as the kidneys respond to the body's fluid balance needs.
Correct Answer is ["C","D"]
Explanation
A. The child should avoid tub baths or submerging in water for several days post-procedure to reduce the risk of infection and keep the catheter site dry; sponge baths are usually recommended.
B. Keeping the child home for an entire week may be excessive; the duration of home care typically depends on the child's recovery, and many children can return to school sooner if they feel well.
C. Offering clear liquids for the first 24 hours helps ensure the child stays hydrated and allows for easier digestion following anesthesia or sedation.
D. Giving acetaminophen for discomfort is appropriate, as it can help manage any pain or discomfort the child may experience after the procedure, and is usually a recommended practice.
