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 C
Explanation
Rationale:
A. Obtaining a peak flow reading is useful for assessing asthma severity but is not the immediate priority in an acute situation.
B. Administering an inhaled glucocorticoid is part of the long-term management of asthma and may not provide immediate relief during an acute exacerbation.
C. Administering a short-acting β-agonist (SABA) is the priority intervention for immediate relief of acute asthma symptoms and helps to quickly open the airways.
D. Determining the cause of the exacerbation is important for long-term management but does not address the immediate need for symptom relief.
