Which statement by an 8-year-old female client with asthma indicates that she understands using a peak expiratory flow meter?
"My peak flow meter can tell me if an asthma episode might be coming, even though I might still be feeling okay."
"always start with the meter reading about halfway up. That way, I don't waste any breath."
use my peak flow meter daily; I will not have an asthma attack."
"When I do my peak flow. I work best if I do three breaths without pausing between breaths."
The Correct Answer is A
A. This statement reflects a proper understanding of the peak flow meter’s purpose — it can help detect early changes in airway function before symptoms are felt, allowing for early intervention and improved asthma control.
B. This reflects a misunderstanding of the correct technique — the meter should be reset to zero before each use, and the child should use a full, fast breath to blow into the meter.
C. While daily monitoring is helpful, the peak flow meter does not prevent asthma attacks — this statement reflects false reassurance and misunderstanding.
D. Peak flow should be measured with a single, forceful breath, not multiple breaths — this indicates incorrect use of the device.

Correct Answer is ["A","B","D","F"]
Explanation
A. Morphine sulfate is used to calm the infant and reduce respiratory effort, which decreases right-to-left shunting of blood and helps improve oxygenation during a "Tet spell."
B. Administering IV fluids increases preload, which can help reduce the severity of the right-to-left shunting by promoting more blood flow to the lungs.
C. Calling a code blue is not typically the first step unless the infant becomes unresponsive or pulseless. Tet spells can often be managed effectively with prompt nursing interventions.
D. Placing the infant in a knee-to-chest position increases systemic vascular resistance, which reduces right-to-left shunting and improves oxygenation.
E. Bronchodilators are used for bronchospasm-related respiratory issues (e.g., asthma), not congenital heart defects like Tetralogy of Fallot.
F. Administering 100% oxygen by face mask helps improve oxygen saturation, although it is not the primary treatment, it supports oxygenation during the episode.
Correct Answer is C
Explanation
A. The pressure dressing is usually removed within 24 hours, not left on for 7 days. Extended dressing use may increase the risk of skin irritation or infection.
B. Strict bed rest is typically recommended for a few hours after the procedure, not for three days. Most adolescents can resume light activity within 24 hours.
C. After a cardiac catheterization, tub baths should be avoided for 2–3 days to prevent infection at the insertion site, but showering is generally safe the next day, provided the site is protected and not scrubbed.
D. Returning to school is typically permitted within 1 to 2 days after the procedure, depending on the child’s condition and physician recommendations—Band-Aid removal is not a relevant factor in determining return to school.
