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 C
Explanation
Having interdisciplinary team meetings for the client on a regular basis.
This action best promotes communication among staff caring for the client because it allows for consistent and coordinated care planning, information sharing, and goal setting for the client who has expressive aphasia and right hemiparesis following a stroke.
Choice A is wrong because posting swallowing precautions at the head of the client’s bed does not promote communication among staff, but rather informs them of the client’s risk of aspiration due to dysphagia, which is a common complication of stroke.
Choice B is wrong because noting changes in the treatment plan in the client’s medical record is a standard practice that does not necessarily enhance communication among staff, but rather documents the client’s progress and interventions.
Choice D is wrong because recording the client’s progress in the nurses’ notes is also a standard practice that does not necessarily enhance communication among staff but rather provides a summary of the client’s status and care.
Expressive aphasia is an acquired language disorder that affects the ability to produce spoken or written language, while right hemiparesis is a weakness or partial paralysis of the right side of the body.
Both of these conditions are caused by damage to the left hemisphere of the brain, which is responsible for language and motor control of the right side of the body. Stroke and traumatic brain injury are common causes of left hemisphere-damage
Correct Answer is D
Explanation
The correct answer is d. Evaluate functioning of the suction device.
Choice D rationale:
- Prompt assessment of the suction device is crucial to determine if it's functioning properly.If the suction is inadequate,it can lead to gastric contents accumulating and potentially causing vomiting.
- Assessing the suction device first allows for timely interventionif it's not working correctly,preventing further complications and discomfort for the client.
Choice A rationale:
- Replacing the NG tube might be necessary if it's dislodged or blocked, but it shouldn't be the immediate action.
- Evaluating the suction device first can help determine if the NG tube itself is the issue or if the problem lies with the suction.
Choice B rationale:
- Providing oral hygiene care is important for comfort and to prevent aspiration, but it's not the priority intervention in this situation.
- Addressing the cause of the vomiting, which could be related to suction malfunction, takes precedence.
Choice C rationale:
- Administering an antiemetic might be helpful to control nausea and vomiting, but it doesn't address the underlying cause.
- Evaluating the suction device first is essential to ensure proper gastric decompression and prevent further vomiting episodes.
