A nurse is collecting data from a 9-month-old infant. Which of the following developmental findings should the nurse expect?
Crude pincer grasp
Shakes head for "no"
Uses two-word phrases
Builds a four-block tower
The Correct Answer is A
A. A 9-month-old infant is expected to demonstrate a crude pincer grasp, which involves picking up small objects between the thumb and forefinger. This is a developmental milestone for this age.
B. While infants may shake their heads by this age, it is typically not used in the context of saying "no." This action is usually a sign of exploration or reaction to stimulation.
C. A 9-month-old typically does not use two-word phrases. By this age, infants are usually babbling and may say single words like "mama" or "dada."
D. A 9-month-old is not expected to build a tower of four blocks. By 12-15 months, infants may begin to stack blocks.

Correct Answer is D
Explanation
A. An increased pulse may occur as a response to a variety of factors, including the infection or the administration of the antibiotic, but it does not necessarily indicate a severe allergic reaction.
B. A maculopapular rash could be a mild allergic reaction or side effect to the antibiotic, but it is not as immediately concerning as wheezing, which could indicate an anaphylactic reaction.
C. A headache can be a side effect of antibiotics, but it is not typically an urgent concern unless accompanied by other signs of severe allergic reactions.
D. Wheezing is a critical finding and could indicate an allergic reaction or anaphylaxis, a potentially life-threatening condition. This symptom requires immediate attention and is the priority to report to the provider.
Correct Answer is C
Explanation
A. The rooting reflex should be present at 1 month of age, not absent. This reflex is triggered when the infant’s cheek is stroked, prompting the baby to turn their head toward the stimulus and open their mouth.
B. A respiratory rate of 64/min is within the expected range for a 1-month-old infant, whose normal respiratory rate is typically between 30–60 breaths per minute.
C. Head lag is normal at 1 month of age when the infant's head is lifted while they are in a sitting position. However, by 4 months of age, the infant should have more head control and reduced head lag.
D. Yellow sclera indicates jaundice, which is common in newborns but should be assessed if present at 1 month to ensure it resolves. By this time, any jaundice should be resolving or gone.
