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.
