A nurse is collecting data from a newborn who is 4 hours old.
Which of the following findings should the nurse report to the provider?
Respiratory rate 24/min.
Heart rate 150/min.
Blood pressure 82/44 mm Hg.
Temperature 37.2° C (99° F).
The Correct Answer is A
Choice A rationale
A respiratory rate of 24 breaths/min in a 4-hour-old newborn is below the normal range, which is typically between 30 and 60 breaths/min. A rate this low could indicate respiratory depression or distress, requiring immediate assessment and intervention by the healthcare provider to ensure adequate oxygenation.
Choice B rationale
A heart rate of 150 beats/min is within the normal physiological range for a newborn, which typically falls between 110 and 160 beats/min. This rate reflects the newborn's circulatory adaptation to extrauterine life and is not a cause for concern in an otherwise stable infant.
Choice C rationale
A blood pressure of 82/44 mm Hg is within the normal range for a term newborn. Normal systolic blood pressure in a newborn is generally between 60-90 mm Hg, and diastolic blood pressure is typically between 30-60 mm Hg, reflecting healthy cardiovascular function and systemic perfusion.
Choice D rationale
A temperature of 37.2° C (99° F) is within the normal range for a newborn's body temperature. The normal axillary temperature for a newborn is typically between 36.5° C and 37.5° C (97.7° F and 99.5° F), indicating appropriate thermoregulation.

Correct Answer is D
Explanation
Choice A rationale
Requesting a parent to verify the newborn's name is an important part of the identification process, but it is not the primary method for confirming identity directly on the newborn. Verifying identity relies on objective comparison of identifying markers on both the infant and the parent for accuracy.
Choice B rationale
Checking the newborn's footprint sheet with the medical record is a valid identification method, but typically occurs when the newborn is admitted or for more permanent records. For immediate transport, a direct comparison of armbands between the newborn and parent is the most efficient and readily verifiable method.
Choice C rationale
Asking a parent to state the newborn's date of birth provides information about the newborn. However, this relies on parental recall and is not a direct physical confirmation of the newborn's identity. Physical identifiers like matching band numbers offer a more secure and immediate verification.
Choice D rationale
Comparing numbers on the newborn's band to the parent's band is the most secure and immediate method to confirm identity prior to transport. This ensures that the correct newborn is being given to the designated parent, preventing potential mix-ups and upholding critical safety protocols in maternity care.
Correct Answer is C
Explanation
Choice A rationale
A blood pressure (BP) of 105/62 mm Hg, while slightly on the lower side of what might be considered a typical adult range (e.g., 120/80 mm Hg), is often within acceptable limits for a postoperative adolescent, especially considering potential mild vasodilation from opioid use. A normal range for adolescent blood pressure can vary, but generally, hypotension is defined as a systolic BP less than 90 mm Hg or symptomatic drop. This finding, while noted, is not immediately life-threatening compared to compromised respiratory function.
Choice B rationale
Urinary retention is a common adverse effect of opioid analgesics due to their anticholinergic-like effects on bladder detrusor muscle contractility and increased sphincter tone. While uncomfortable and requiring intervention (e.g., straight catheterization), it is not an immediate life-threatening concern compared to respiratory depression. A normal bladder capacity is approximately 300-500 mL, and the urge to void typically occurs at 150-200 mL. Persistent urinary retention can lead to bladder distention, pain, and increased risk of urinary tract infection, but it doesn't pose the same acute physiological threat as respiratory depression.
Choice C rationale
A respiratory rate of 11/min is a finding that warrants immediate attention and is the nurse's priority. Opioid analgesics, such as morphine, are known to cause respiratory depression by acting on opioid receptors in the brainstem, decreasing the sensitivity of the respiratory center to carbon dioxide. A normal respiratory rate for an adolescent typically ranges from 12 to 20 breaths per minute. A rate of 11/min is considered bradypnea and indicates potential hypoventilation, which can lead to hypoxemia and hypercapnia, posing a significant risk to the patient's oxygenation and overall physiological stability.
Choice D rationale
Blurred vision can be an adverse effect of opioid medications, often related to miosis (pupil constriction) or effects on accommodation. While it can impair the patient's comfort and ability to ambulate safely, it is not a life-threatening priority in the immediate postoperative period compared to respiratory compromise. This visual disturbance typically resolves as the medication is metabolized and excreted. Normal visual acuity is typically 20/20. .
