The practical nurse (PN) is caring for an older client who is receiving chemotherapy for lung cancer. Which finding is the highest priority for the PN to report to the charge nurse?

Reference ranges:

Blood urea nitrogen (BUN): [Adult: 10 to 20 mg/dL or 3.6 to 7.1 mmol/L] Platelets: [150,000 to 400,000/mm3 or 150 to 400 x 10^9/L]

Circumoral cyanosis is a bluish discoloration around the mouth that indicates inadequate oxygenation. It is an abnormal finding in a full-term newborn and requires immediate assessment and intervention by the PN.

The other options are not correct because:

1. A positive Babinski's reflex is a normal finding in newborns that indicates intact neurological function. It is elicited by stroking the sole of the foot and observing the fanning of the toes.
2. A negative Ortolani's sign is a normal finding in newborns that indicates no hip dislocation or dysplasia. It is elicited by abducting the hips and feeling for any clicking or clunking sensation.
3. A large sacral "stork bite" is a common benign birthmark that appears as a reddish patch on the lower back or nape of the neck. It usually fades within the first year of life and does not require any treatment.
4. 

The correct answer is choice D, Pupils reactive to accommodation. Choice A rationale:

"Peripheral vision intact”. refers to the ability to see objects at the outer edges of one's visual field. It is not relevant to the assessment of pupillary response and does not describe the finding of pupils constricting as they change focus from a far object to a near object.

Choice B rationale:

"Nystagmus present with pupillary focus”. suggests involuntary rapid eye movements accompanied by changes in pupillary response. Nystagmus is not an expected finding during pupillary accommodation, and its presence would indicate a neurological issue rather than a normal response.

Choice C rationale:

"Consensual pupillary constriction present”. refers to both pupils constricting when light is shined into one eye. While this finding is normal, it does not specifically describe the pupils' response during accommodation when focusing from a far object to a near object.

Choice D rationale:

"Pupils reactive to accommodation”. accurately describes the normal physiological response of the pupils constricting as they change focus from a distant object to a nearby object. This response ensures that the appropriate amount of light enters the eyes to maintain clear vision during different distances of focus.
