A nurse is caring for a newborn and assessing newborn reflexes.
To elicit the Moro reflex, what action should the nurse take?
Turn the newborn’s head quickly to one side.
Perform a sharp hand clap near the infant.
Place a finger at the base of the newborn’s toes.
Hold the newborn vertically allowing one foot to touch the table surface.
The Correct Answer is B
Choice A rationale
Turning the newborn’s head quickly to one side does not elicit the Moro reflex. This action can elicit the tonic neck reflex, also known as the “fencing” reflex.
Choice B rationale
Performing a sharp hand clap near the infant can elicit the Moro reflex. This reflex is a response to a sudden loss of support and involves three distinct components: spreading out the arms (abduction), unspreading the arms (adduction), and usually crying.
Choice C rationale
Placing a finger at the base of the newborn’s toes elicits the Babinski reflex, not the Moro reflex.
Choice D rationale
Holding the newborn vertically allowing one foot to touch the table surface does not elicit the Moro reflex. This action can elicit the stepping or walking reflex.

Correct Answer is D
Explanation
Choice A rationale
While changes in an infant’s sleep patterns can be a sign of many issues, they are not a specific indicator of a food allergy.
Choice B rationale
Rice cereals are typically one of the first foods introduced to infants and are usually well- tolerated. They are not known to cause problems during lactation.
Choice C rationale
The foods a mother eats can affect breast milk, but they do not typically cause food allergies. Most babies can tolerate a variety of foods in a mother’s diet without any problems.
Choice D rationale
If there is a strong family history of peanut allergies, the mother might want to avoid eating peanuts while breastfeeding. However, current research suggests that early exposure to potential allergens may actually decrease the risk of developing allergies.
Correct Answer is B
Explanation
To calculate the estimated date of birth (EDB) using the first day of the last menstrual period (LMP), you can use Naegele’s Rule. This rule adds 280 days (or 40 weeks) to the first day of the LMP.
Given the LMP of July 27 (0727):
- Add 1 year: July 27, 2023 becomes July 27, 2024.
- Add 7 days: July 27, 2024 becomes August 3, 2024.
- Subtract 3 months: August 3, 2024 becomes May 3, 2024.
So, the estimated date of birth (EDB) is May 3, 2024 (0503).
