A nurse in an emergency department is caring for a client following a motor-vehicle crash. The client’s Glasgow coma scale rating is 15.
Which of the following findings should the nurse expect?

The correct answer is choice D: A client who is taking warfarin and has an INR of 1.8.

Choice A rationale:

A Mantoux test with an induration after 48 hours can be a normal reaction, especially if the induration is within the expected size range for a positive result, depending on the individual’s risk factors and history. It does not necessarily require follow-up care unless the induration is significantly large or there are other concerning symptoms.

Choice B rationale:

A client scheduled for a colonoscopy and taking sodium phosphate does not typically require follow-up care for the sodium phosphate intake itself. Sodium phosphate is commonly used as a bowel prep medication to clear the intestines prior to the procedure.

Choice C rationale:

A potassium level of 3.6 mEq/L is within the normal range (3.5-5.0 mEq/L), so a client taking bumetanide with this potassium level would not typically require follow-up care for the potassium level alone.

Choice D rationale:

A client taking warfarin with an INR of 1.8 requires follow-up care because the therapeutic range for warfarin is typically between 2.0 and 3.0 for most indications. An INR of 1.8 may indicate that the blood is not “thin” enough, increasing the risk of thrombotic events, and the warfarin dose may need adjustment.

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 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 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 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
