A nurse is preparing to measure an infant’s vital signs.
Which of the following sites should the nurse use to assess the heart rate?
Carotid artery
Brachial artery
Apex of the heart
Radial artery .
The Correct Answer is C
Choice C rationale
The apex of the heart is the most appropriate site to assess an infant’s heart rate. In infants, the apical pulse provides the most accurate assessment of heart rate. The apical pulse is located at the fifth intercostal space at the midclavicular line.
Choice A rationale
The carotid artery is not typically used to assess an infant’s heart rate. This site is more commonly used in adults and older children.
Choice B rationale
The brachial artery can be used to assess an infant’s heart rate, but it is typically used for blood pressure measurements rather than heart rate assessments.
Choice D rationale
The radial artery is not typically used to assess an infant’s heart rate. This site is more commonly used in adults and older children.

Correct Answer is B
Explanation
Choice A rationale
Maternal bradycardia refers to a slower than normal heart rate in the mother. While it can affect the baby’s health, it doesn’t cause late decelerations on the fetal monitor.
Choice B rationale
Late decelerations are caused by uteroplacental insufficiency, which is a decrease in the blood flow to the placenta that reduces the amount of oxygen and nutrients transferred to the fetus. This is why the nurse would interpret late decelerations as indicating uteroplacental insufficiency.
Choice C rationale
Umbilical cord compression can cause variable decelerations, not late decelerations. Variable decelerations are abrupt decreases in the fetal heart rate, typically associated with contractions, and they vary in onset, depth, and duration.
Choice D rationale
Fetal head compression typically causes early decelerations, not late decelerations. Early decelerations are a mirror image of the contraction and are generally not a concern.
Correct Answer is B
Explanation
Choice A rationale
While it’s important to assess the level of parental anxiety related to the diagnosis, it’s not the immediate priority. The child’s physical health needs to be stabilized first.
Choice B rationale
This is the correct answer. Auscultating the rate and characteristics of the child’s heart sounds is the immediate priority. Acute rheumatic fever can lead to serious cardiac complications, so it’s crucial to monitor the child’s heart function closely.
Choice C rationale
While assessing the severity of joint pain is important in managing the child’s comfort, it’s not the immediate priority. The child’s heart function needs to be assessed first.
Choice D rationale
While assessing the client’s erythematous rash is part of the overall assessment of a child with acute rheumatic fever, it’s not the immediate priority. The child’s heart function needs to be assessed first.
