A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks the nurse what is the purpose of the ointment. Which response by the nurse will best explain the purpose for administering the ointment?
The ointment will dilate the pupil so the red reflex can be visualized.
The ointment will prevent a herpes infection.
The ointment will prevent eye infections.
The ointment will clear the infants's vision
The Correct Answer is C
Choice A rationale
The ointment used in newborns does not dilate the pupil. It is not intended to aid in the visualization of the red reflex. The red reflex can be observed without the need for any ointment.
Choice B rationale
The ointment does not prevent herpes infections. It is specifically used to prevent bacterial eye infections caused by organisms such as Neisseria gonorrhoeae and Chlamydia trachomatis, which can be present in the birth canal.
Choice C rationale
The ointment will prevent eye infections. This is the correct explanation. The eye ointment, typically erythromycin or tetracycline, is applied to prevent ophthalmia neonatorum, a type of conjunctivitis caused by bacteria that the newborn might be exposed to during delivery.
Choice D rationale
The ointment will not clear the infant's vision. Newborns naturally have somewhat blurry vision at birth, and the ointment does not enhance or clear their vision. Its primary purpose is to prevent bacterial infections.

Correct Answer is B
Explanation
Choice A rationale
Rooting is a reflex that helps a baby find and latch onto the breast or bottle for feeding. While the rooting reflex may diminish as the baby grows, it is not the primary indicator for introducing solid foods. Other developmental milestones are more relevant for this transition.
Choice B rationale
When a baby starts opening their mouth in response to the sight or smell of food, it indicates a readiness to try solid foods. This behavior shows that the baby is interested in and capable of learning to eat from a spoon, which is a key step in the introduction of solids.
Choice C rationale
Awakening once for nighttime feedings is common for infants and does not necessarily indicate readiness for solid foods. Nighttime awakenings can occur for various reasons, including hunger, but other developmental signs should be considered for introducing solids.
Choice D rationale
Giving up a bottle for a cup is a milestone that typically occurs later in infancy or toddlerhood. It is not directly related to the introduction of solid foods, which generally begins around 4 to 6 months of age based on the child's developmental readiness and interest in food.
Correct Answer is ["2.3"]
Explanation
Step 1 is to convert the child's weight from pounds to kilograms. 16 pounds ÷ 2.2 = 7.3 kg.
Step 2 is to calculate the total daily dose in mg. 25 mg/kg × 7.3 kg = 182.5 mg.
Step 3 is to determine the dose per administration, divided by 2 since the dose is given every 12 hours. 182.5 mg ÷ 2 = 91.25 mg.
Step 4 is to convert the dose from mg to mL using the concentration of the medication. 91.25 mg ÷ (200 mg/5 mL) = 91.25 ÷ 40 = 2.3 mL per dose. The answer is 2.3 mL.
