The physician orders Benadryl elixir 37.5 mg po for hives. Available: 12.5mg/5 mL. How many milliliters will the nurse administer?

Client A has normal vital signs except for a mild fever, no urgent intervention needed.

Client B shows mild tachycardia and increased respiratory rate, but oxygen saturation and blood pressure remain stable, requires monitoring but not immediate action.

Client C has fever, tachycardia, and tachypnea, suggesting infection or dehydration. While assessment is needed, the patient is not in immediate distress compared to Client D.

Client D requires immediate nursing intervention due to the following critical findings: Bradycardia which may indicate poor perfusion, conduction abnormalities, or medication side effects, bradypnea can signal respiratory depression or impending failure, hypotension suggests shock or decreased perfusion, which may lead to organ failure and hypoxia, oxygen saturation below 90% is a critical finding and requires immediate intervention.

A. Record the pulse as "0" (zero) for that site. A pulse should never be documented as absent without first using a Doppler device to confirm whether blood flow is present.
B. Use a Doppler device to locate and assess the pulse. If a pulse is difficult to palpate, a Doppler ultrasound should be used to detect blood flow before making any conclusions about circulation status.
C. Come back in 15 minutes and reassess. If the pulse is weak or difficult to locate, immediate assessment with a Doppler is needed instead of delaying evaluation.
D. Report the finding to the physician. While a physician should be notified if a pulse remains undetectable even with a Doppler, the nurse must first verify the absence of a pulse before escalating the concern.
