A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?

Choice A reason:

"This test will be repeated when your baby is 2 months old. “This is a false statement. Newborn genetic screening is usually performed shortly after birth. The test is not typically repeated when the baby is 2 months old, as it is meant to detect conditions early on, allowing for prompt intervention and management if necessary.

Choice B reason:

"Your baby will be given 2 ounces of water to drink prior to the test."This is a false statement. The baby does not need to drink water before the newborn genetic screening test. The test is usually performed by collecting a small blood sample from the baby's heel, and there is no need for the baby to drink water beforehand.

Choice C reason:

"This test should be performed after your baby is 24 hours old. “This is the appropriate statement. The nurse should include the statement that newborn genetic screening should be performed after the baby is 24 hours old. Newborn genetic screening, also known as newborn screening or heel prick test, is a standard test performed on newborns to detect certain genetic, metabolic, and congenital disorders early on. The test is typically done by pricking the baby's heel to collect a small sample of blood, which is then analysed in a laboratory.

Choice D reason:

"A nurse will draw blood from your baby's inner elbow. “This is a false statement. The correct location for collecting the blood sample for newborn genetic screening is the baby's heel. The nurse will prick the baby's heel to obtain a few drops of blood, which will then be collected on a special filter paper for laboratory analysis.

The correct answer is B.

Choice A reason: Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.

Choice B reason: First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.

Choice C reason: Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.

Choice D reason: Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.
