A nurse is caring for a newborn whose mother was taking methadone during her pregnancy.
Which of the following findings indicates the newborn is experiencing withdrawal?
Acrocyanosis
Bradycardia
Bulging fontanels
Hypertonicity
The Correct Answer is D

Hypertonicity is a sign of increased muscle tone and stiffness, which can indicate that the newborn is experiencing withdrawal from methadone exposure in utero. Methadone is an opioid medication that can cross the placenta and cause neonatal abstinence syndrome (NAS) in the newborn.
Choice A, acrocyanosis, is wrong because it is a normal finding in newborns.
Acrocyanosis is a bluish discoloration of the hands and feet due to immature peripheral circulation. It usually resolves within the first 24 to 48 hours of life.
Choice B, bradycardia, is wrong because it is not a typical sign of withdrawal.
Bradycardia is a slow heart rate, usually less than 100 beats per minute in newborns. It can be caused by hypoxia, hypothermia, hypoglycemia, or vagal stimulation.
Choice C, bulging fontanels, is wrong because it is a sign of increased intracranial pressure, not withdrawal. Bulging fontanels can be caused by meningitis, hydrocephalus, or hemorrhage.
Normal ranges for newborn vital signs are as follows:
- Heart rate: 120 to 160 beats per minute
- Respiratory rate: 30 to 60 breaths per minute
- Temperature: 36.5 to 37.5°C (97.7 to 99.5°F)
- Blood pressure: 60 to 80 mm Hg systolic and 40 to 50 mm Hg diastolic

Correct Answer is A
Explanation
Explanation:
"I will use a cool-mist vaporizer in my baby's room." This statement demonstrates an understanding of the teaching. Using a cool-mist vaporizer can help maintain moisture in the air and alleviate nasal congestion in infants.
Incorrect:
B- "I will leave my baby's bib on while he is sleeping." This statement indicates a lack of understanding. It is not safe to leave a bib on an infant while they are sleeping as it can pose a suffocation risk.
C- "I will leave the plastic covering on the crib mattress." This statement indicates a lack of understanding. The plastic covering on the crib mattress should be removed as it can pose a suffocation hazard.
D- "I will lay my baby's head on a pillow while he is in the crib." This statement indicates a lack of understanding. Pillows should not be used in the crib for infants as they can increase the risk of suffocation and SIDS (Sudden Infant Death Syndrome).
Correct Answer is A
Explanation
Choice A reason:
"Plan to take this medication with food." Is the correct statement. When providing instructions to an older adult client who has a seizure disorder and is prescribed phenytoin (an antiepileptic or anticonvulsant medication), the nurse should advise the client to take the medication with food. Phenytoin can cause gastrointestinal irritation, and taking it with food can help minimize this side effect.
Choice B reason:
"Plan to take this medication with antacids. “is not the appropriate instruction. Phenytoin should not be taken with antacids. Antacids can reduce the absorption of phenytoin, leading to decreased effectiveness of the medication. If antacids are needed for other reasons, they should be taken at least 2 hours before or after taking phenytoin.
Choice C reason:
"Limit foods that contain vitamin D while taking this medication. “This is not inappropriate instruction. There is no specific requirement to limit foods containing vitamin D while taking phenytoin. However, phenytoin may decrease the absorption of vitamin D, which could potentially affect the client's vitamin D levels. Therefore, it is essential for the client to have regular check-ups and possibly discuss the need for vitamin D supplementation with their healthcare provider.
Choice D reason:
"Limit foods that contain folic acid while taking this medication. “This is not the correct statement. Phenytoin can interfere with the absorption of folic acid (a B-vitamin). Long-term use of phenytoin may lead to folic acid deficiency. Therefore, the nurse should instruct the client to consume foods rich in folic acid and discuss the potential need for folic acid supplementation with their healthcare provider.
