A nurse is assisting to collect data for a gestational age assessment on a newborn. Which of the following should the nurse check during a neuromuscular assessment? (Select all that apply.)

Heel to ear

Popliteal angle

Moro reflex

Scarf sign

Arm recoil

Answer and Explanation

Correct Answer : A,B,D,E

Choice A reason:

Heel to ear is a test that measures the flexibility of the newborn's hip and knee joints. The nurse should gently flex the newborn's hip and knee and bring the foot toward the ear on the same side. The closer the foot is to the ear, the higher the score. This test is part of the neuromuscular assessment for gestational age.

Choice B reason:

Popliteal angle is a test that measures the angle of flexion at the knee joint. The nurse should flex the newborn's hip and knee at 90 degrees and then extend the lower leg until resistance is felt. The smaller the angle, the higher the score. This test is also part of the neuromuscular assessment for gestational age.

Choice C reason:

Moro reflex is a test that evaluates the newborn's startle response. The nurse should hold the newborn in a semi-sitting position and then allow the head to fall back slightly. The newborn should extend and abduct the arms and legs, then flex and adduct them. This test is not part of the neuromuscular assessment for gestational age, but rather a reflex assessment for neurological function. •

Choice D reason:

Scarf sign is a test that measures the flexibility of the newborn's shoulder and elbow joints. The nurse should draw one of the newborn's arms across the chest toward the opposite shoulder. The farther the elbow can be moved across the body, the lower the score. This test is part of the neuromuscular assessment for gestational age.

Choice E reason:

Arm recoil is a test that measures the degree of flexion at the elbow joint. The nurse should extend both of the newborn's arms for 5 seconds and then release them. The arms should return to a flexed position quickly and fully. The faster and more complete the recoil, the higher the score. This test is part of the neuromuscular assessment for gestational age.

Correct Answer is B

Explanation

Choice A reason:

Diminished deep-tendon reflexes are a sign of magnesium toxicity, not safety. Magnesium sulfate is a central nervous system depressant that can cause muscle weakness, respiratory depression, and cardiac arrest if given in excess. The nurse should monitor the client's deep-tendon reflexes and stop the infusion if they are absent or reduced.

Choice B reason:

A respiratory rate of 16/min is a normal finding and indicates that the client is not experiencing respiratory depression from magnesium sulfate. The nurse should monitor the client's respiratory rate and stop the infusion if it falls below 12/min.

Choice C reason:

A heart rate of 60/min is a normal finding and indicates that the client is not experiencing bradycardia from magnesium sulfate. The nurse should monitor the client's heart rate and stop the infusion if it falls below 50/min.

Choice D reason:

Urine output of 50 mL in 4 hr is a sign of oliguria, not safety. Magnesium sulfate can cause renal impairment and fluid retention if given in excess. The nurse should monitor the client's urine output and stop the infusion if it falls below 30 mL/hr.

A. Moro B. Rooting C. Gag D. Running E. Babinski F. Stepping G. Crawling Reflex H. Standing with Support I. Pincer Grasp

Correct Answer is ["A","B","C","E","F"]

Explanation

Choice A reason:

Moro is a newborn reflex that occurs when the baby is startled by a loud sound or movement. The baby will cry, throw back his or her head, and then pull his or her limbs into the body. This reflex lasts until the baby is about 2 months old.

Choice B reason:

Rooting is a newborn reflex that starts when the corner of the baby's mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.

Choice C reason:

Gag is a newborn reflex that prevents the baby from choking on foreign objects. The baby will cough, gag or spit out anything that touches the back of the throat or the roof of the mouth. This reflex is present throughout life.

Choice D reason:

Running is not a newborn reflex. It is a voluntary movement that develops later in childhood. Choice E reason:

Babinski is a newborn reflex that occurs when the sole of the foot is stroked from heel to toe. The baby will fan out and curl up the toes and twist the foot inward. This reflex lasts until the baby is about 12 months old.

Choice F reason:

Stepping is a newborn reflex that occurs when the baby is held upright with his or her feet touching a solid surface. The baby will appear to take steps or dance. This reflex lasts about 2 months.

Choice G reason:

The crawling reflex is a developmental milestone observed in infants around 6-8 months of age. It involves the baby moving on their hands and knees, often starting with a belly-crawling motion. Unlike newborn reflexes, this skill is learned and requires muscle coordination and strength.

Choice H reason:

Standing with support is a developmental milestone typically achieved by infants around 9-12 months. In this skill, the baby pulls themselves up to a standing position while holding onto furniture or a caregiver’s hands. It is a learned behavior reflecting increased muscle strength and balance, distinct from newborn reflexes.

Choice I reason:

The pincer grasp is a fine motor skill that usually develops between 8-12 months. It involves the baby using the thumb and index finger to pick up small objects. This ability is not a reflex but a learned skill that demonstrates improved hand-eye coordination and dexterity.
