A nurse in a provider's office is collecting baseline preoperative data from a 5-month-old infant who has coarctation of the aorta. Which of the following locations should the nurse palpate to check for the presence of the infant's femoral pulse?
Explanation & Rationale
A: Location A is near the infant’s foot, specifically around the ankle. This area is where the posterior tibial or dorsalis pedis pulse would be palpated, not the femoral pulse. These pulses are important for assessing peripheral circulation but are not the primary site for evaluating coarctation of the aorta, which requires checking central pulses like the femoral. B: Location B is at the upper inner thigh, near the groin, where the femoral artery passes close to the skin surface. This is the correct site for palpating the femoral pulse in an infant. In conditions like coarctation of the aorta, comparing the strength of the brachial and femoral pulses is crucial to detect differences in blood flow between the upper and lower body. C: Location C is on the upper arm, near the shoulder area, which corresponds to the location for checking the brachial pulse. The brachial pulse is commonly used in infants to assess heart rate, especially during resuscitation efforts. However, it is not the site for assessing femoral pulse strength, which is needed when evaluating for coarctation of the aorta.
