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?

Apex of the heart

Carotid artery

Brachial artery

Radial artery

Answer and Explanation

The Correct Answer is A

A. Apex of the heart: The apex of the heart is the preferred site for measuring an infant's heart rate. It is located at the 4th or 5th intercostal space, just medial to the midclavicular line, allowing for accurate auscultation of the heartbeat.

B. Carotid artery: While the carotid artery can be used to assess heart rate in older children and adults, it is not ideal for infants due to the risk of compromising circulation to the brain if pressure is applied too forcefully.

C. Brachial artery: The brachial artery is often used to assess pulse in infants, especially in cases of CPR, but it is not the preferred site for routine heart rate measurement. It may be used when assessing circulation or checking for pulses, but auscultation at the apex is more accurate for heart rate.

D. Radial artery: The radial artery can be difficult to palpate in infants due to their small size and is generally not used for heart rate assessment in this age group. The apex is a more reliable location.

Correct Answer is A

Explanation

A. "I will keep my baby in an upright position after feedings."
Gastroesophageal reflux (GER) is a condition where the stomach contents flow back into the esophagus, which can cause spitting up or regurgitation in infants. Keeping the baby in an upright position after feedings can help reduce the likelihood of reflux episodes. By holding the baby in an upright position for about 30 minutes after feeding, gravity can aid in keeping the stomach contents from flowing back into the esophagus.
The other statements are incorrect or do not address the management of gastroesophageal reflux:
B. "My baby's formula can be thickened with oatmeal." - Thickening formula with oatmeal is not a standard recommendation for managing GER in infants. In some cases, thickening formulas may be recommended, but it should be done under the guidance of a healthcare provider.
C. "I should position my baby side-lying during sleep." A side-lying position is not recommended for sleep in infants, as it increases the risk of sudden infant death syndrome (SIDS). The safe sleep position for infants is on their back.
D. "I will have to feed my baby formula rather than breast milk." - The type of feeding (formula or breast milk) does not directly impact the occurrence of gastroesophageal reflux. Both breast milk and formula can cause reflux in some infants. It is essential to discuss feeding options with a healthcare provider to determine the best approach for the individual infant's needs.

A. Respiratory rate 20/min B. Abdominal pain rated 4 on a scale of 0 to 10 C. Heart rate 72/min D. Blood pressure 92/50 mm Hg

Correct Answer is D

Explanation

The nurse's priority assessment finding in an adolescent who experienced blunt trauma to the abdomen is low blood pressure (hypotension). Hypotension could indicate significant internal bleeding or hemorrhage, which is a life-threatening condition and requires immediate attention. The decreased blood pressure may be a sign of shock, and prompt intervention is needed to stabilize the client's condition and prevent further deterioration.

While all the other findings (respiratory rate, abdominal pain, and heart rate) are important and should be assessed and monitored, blood pressure is the most critical in this situation due to its potential association with severe internal injuries and the risk of hypovolemic shock.
