A nurse is preparing to measure an infant's vital signs. The nurse should use which of the following sites to assess a heart rate?
Brachial artery
Radial artery
Apex of the heart
Carotid artery
The Correct Answer is A
Rationale:
A. The brachial artery is commonly used to assess the heart rate in infants due to its accessibility and the ease of palpation in smaller limbs.
B. The radial artery is not typically used in infants because it is less accessible and not as easily palpated in this age group.
C. While the apex of the heart is where heart sounds are best auscultated, it is not used to palpate the pulse in infants.
D. The carotid artery is not typically used for assessing the heart rate in infants due to the risk of applying excessive pressure.

Correct Answer is ["B","D"]
Explanation
Rationale:
A. Nighttime symptoms occurring twice a month is more characteristic of intermittent asthma rather than mild persistent asthma, which might present with nighttime symptoms more frequently.
B. In mild persistent asthma, the peak expiratory flow (PEF) is typically greater than or equal to 80% of the predicted value, indicating relatively good control of asthma symptoms.
C. Continuous symptoms throughout the day are not typical for mild persistent asthma; symptoms usually occur intermittently.
D. Minor limitations with normal activity are expected in mild persistent asthma, as the condition can cause some restrictions in daily activities but not severe impairments.
E. Daytime symptoms occurring more than twice a week align with moderate persistent asthma, not mild persistent asthma.
Correct Answer is C
Explanation
Rationale:
A. Reading a story is beneficial but does not directly support the toddler's developmental task of autonomy and initiative.
B. Feeding the toddler is a basic need but does not support the development of independence.
C. Allowing the toddler to pull a talking-duck toy supports their developmental task of autonomy and initiative by promoting physical activity and exploration.
D. Watching a puppet show is a passive activity and does not foster the active exploration needed for this developmental stage.
