Final answer:
Infant vitals should have an RR of 30-40 breaths per minute, an HR of 100-160 beats per minute, and an SBP of 70-100 mm Hg. Heart rate and respiration rates are key components of the Apgar score, which assesses a newborn's health.
Step-by-step explanation:
The correct range of vitals for an infant in terms of respiratory rate (RR), heart rate (HR), and systolic blood pressure (SBP) according to the question should be: 30-40 breaths per minute for RR, 100-160 beats per minute for HR, and 70-100 mm Hg for SBP. The Apgar score evaluates a newborn's health, with heart rate and respiration being crucial indicators of the infant's condition. Normal respiratory rates for a child gradually decrease from birth to adolescence, starting from 30-60 breaths per minute for infants under one year. As for the heart rate, newborn resting rates can be around 120 bpm and will decrease into young adulthood before increasing again later in life.
An infant's pulse rate will have a certain uncertainty depending on the measured rate and the potential error. For example, if an infant's pulse rate is measured to be 130 ± 5 beats/min, the percent uncertainty can be calculated to identify the precision of the measurement.
