Which of the following represents normal infant vital signs?

The chosen answer accurately reflects the normal vital signs for infants. In infants, the typical ranges for pulse, respiratory rate (RR), and blood pressure (BP) are significantly different from those of adults due to their rapid growth and development.

For infants, the normal pulse rate generally falls within the range of 110 to 160 beats per minute, which aligns with the option selected. This elevated pulse rate is indicative of the higher metabolic demands placed on an infant’s body compared to older children and adults.

The respiratory rate for infants is also higher than that of adults, typically falling between 30 to 60 breaths per minute. The selected choice adheres to this expected range, indicating adequate respiratory function and effort for a healthy infant.

Blood pressure in infants can vary, but the typical systolic blood pressure can range from around 60 to 80 mmHg in normal circumstances, which is represented in the selected option. This range is sufficient and shows that the infant's cardiovascular system is functioning appropriately.

Together, the ranges in the chosen answer reflect normal vital signs for infants, demonstrating both their physiological differences and the various factors that influence their vital parameters.
