A nurse is caring for a client who is in active labor and notes the FHR baseline has been 100/min for the past 15 min.

The nurse should identify which of the following conditions as a possible cause of fetal bradycardia?

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

Obtain the specimen from the retention port. This is because the retention port is a sterile site that can be accessed by a syringe to aspirate urine without contaminating the specimen or the closed drainage system. The retention port should be cleaned with an alcohol swab before inserting the syringe. The specimen should be transferred to a sterile container and labeled appropriately.

Choice A is wrong because unclamping the collection port below the bag would allow urine to flow out of the bag, which is not sterile and may contain bacteria or sediment. Choice C is wrong because disconnecting the catheter from the collection tubing would break the closed drainage system and increase the risk of infection. Choice D is wrong because using the balloon port to obtain the sterile specimen would deflate the balloon that holds the catheter in place and cause trauma to the bladder wall.

Normal ranges for urine characteristics vary depending on the type of analysis, but some general parameters are:

• Color: pale yellow to amber
• Clarity: clear or slightly cloudy
• Odor: faint aromatic
• pH: 4.5 to 8.0
• Specific gravity: 1.005 to 1.030
• Protein: <150 mg/24 hr
• Glucose: negative
• Ketones: negative
• Blood: negative
• Nitrites: negative
• Leukocyte esterase: negative
• Bacteria: <10,000 CFU/mL
