Answer and Explanation

The Correct Answer is A

A. An infant's rate is 90 bpm.

An infant's normal heart rate typically ranges from 70 to 150

B. A toddler's rate is 150 bpm.

The normal heart rate for a preschooler typically ranges from 80 to 120 bpm, with an average rate around 100-110 bpm. A rate of 130 bpm would be considered tachycardia in a preschooler.

Correct Answer is C

Explanation

A. Carotid artery: The carotid artery is not typically used to assess heart rate in infants due to its location and difficulty in palpation.

B. Radial artery: The radial artery is not typically used to assess heart rate in infants, especially in non-cooperative or newborn infants.

C. Apex of the heart: Assessing the heart rate by auscultating the apex of the heart with a stethoscope is the most accurate method for infants.

D. Brachial artery: The brachial artery is not typically used to assess heart rate in infants. It is commonly used to measure blood pressure.

A. The toddler's anterior fontanel is not fully closed. B. The toddler gained 3 in in height since last year. C. The toddler gained 4 lb in weight since last year. D. The circumference of the child's head increased 1 in since last year.

Correct Answer is A

Explanation

A. The toddler's anterior fontanel is not fully closeD. The closure of the anterior fontanel typically occurs by around 18 months of age. If the fontanel is still open at 3 years old, it may indicate a delay in normal development and could be a cause for concern. The nurse should further assess this finding and consider follow-up with the healthcare provider.

B. The toddler gained 3 in in height since last year: Growth in height is expected during early childhood, and a gain of 3 inches over a year is within the normal range for a 3-year-old.

C. The toddler gained 4 lb in weight since last year: Weight gain is also expected during early childhood, and a gain of 4 pounds over a year is within the normal range for a 3-year-old.

D. The circumference of the child's head increased 1 in since last year: Head circumference typically increases during early childhood as the brain grows, and a 1-inch increase over a year is within the normal range for a 3-year-old.
