A nurse is preparing to administer an oral medication to a preschooler. Which of the following actions should the nurse take to encourage acceptance of the medication?

A. Urine output of 15 mL in the last 2 hr: Urine output is a critical indicator of kidney function. For a toddler weighing 12 kg, an output of less than 1 ml/kg/hr (in this case, 12 mL/hr) is concerning and might suggest dehydration or kidney dysfunction.

B. Pedal and posterior tibial pulses of 2+ are considered normal for pulses in the lower extremities.

C. A skin temperature of 36°C (96.8°F) is slightly on the low side but not a critical finding in isolation.

D. Drainage from the chest tube is expected after open heart surgery. The amount (22 mL in an hour) might need monitoring depending on the specifics of the surgery, but it's not necessarily a red flag on its own.

A. "Let's review the side effects of metronidazole.” Metronidazole is used to treat bacterial infections like bacterial vaginosis and trichomoniasis, not syphilis. Syphilis is typically treated with penicillin or other appropriate antibiotics.

B. “I have to contact your parents.” At 20 years old, the patient is an adult and has a right to medical privacy. Contacting their parents without consent would violate patient confidentiality laws.

C. “You need to come back in a week for retesting" Retesting is important in the follow-up for sexually transmitted infections, but it is usually scheduled for a later date (e.g., after treatment is completed and time has passed to check for cure or reinfection). A week is too soon for meaningful retesting for syphilis.

D. “I have to notify the public health department.” Syphilis is a reportable disease, meaning healthcare providers are required to notify public health authorities to help control the spread of the infection. This is necessary for public health tracking and intervention.
