Correct Answer is D
Explanation
A. Assess pupillary response to light hourly: Dopamine administration may cause changes in pupillary response, but it is not the primary concern associated with its administration. Hourly pupillary assessment may not be necessary unless other signs of neurological changes are present.
B. Initiate seizure precautions: While dopamine administration may cause neurological effects, such as agitation or tremors, it is not typically associated with seizure activity. Seizure precautions are not indicated solely due to dopamine infusion.
C. Monitor serum potassium frequently: Dopamine administration can affect potassium levels, but monitoring serum potassium levels frequently may not be necessary unless the client has pre- existing potassium imbalances or is at risk for electrolyte disturbances.
D. Measure urinary output every hour: Dopamine is a vasopressor medication that can increase blood pressure and cardiac output, potentially leading to increased renal perfusion and urinary output. Monitoring urinary output hourly is essential to assess the client's response to dopamine therapy and ensure adequate renal function.
Correct Answer is A
Explanation
A. This hernia is a normal variation that resolves without treatment: Umbilical hernias are common in infants and usually resolve on their own by around 1 to 2 years of age without any specific treatment.
B. An abdominal binder can be worn daily to reduce the protrusion: Using an abdominal binder is not recommended for treating umbilical hernias in infants, as they typically resolve spontaneously and do not require intervention.
C. Restrictive clothing will be adequate to help the hernia go away: Restrictive clothing is not necessary and will not affect the resolution of an umbilical hernia in infants.
D. The quarter should be secured with an elastic bandage wrap: Securing a quarter over the umbilicus with an elastic bandage wrap is not an appropriate treatment for an umbilical hernia and may cause harm.
