A nurse is providing care to a client who presents with manifestations consistent with bacterial meningitis. After evaluating the client and completing a head CT scan, the provider delays performing a lumbar puncture and orders a corticosteroid combined with antibiotics. The nurse knows that the lumbar puncture has most likely been delayed for what reason?
The provider wants to avoid lasting health complications.
The client has elevated intracranial pressure.
The client has experienced a seizure.
The provider already knows which pathogen the client has.
The Correct Answer is B
A. Avoiding lasting health complications is always a goal, but this is not the primary reason for delaying the lumbar puncture.
B. Elevated intracranial pressure is a concern as performing a lumbar puncture could cause brain herniation in such cases.
C. While seizures can occur with bacterial meningitis, they are not a primary reason for delaying a lumbar puncture.
D. Knowing the pathogen does not negate the need for a lumbar puncture for definitive diagnosis and cerebrospinal fluid analysis.

Correct Answer is ["15","994"]
Explanation
To calculate the infusion rate in mL/hr for administering dopamine at 10 mcg/kg/min for a client weighing 85.3 kg, you would first convert the weight to micrograms by multiplying by 1,000,000 (since there are 1,000,000 micrograms in a kilogram). This gives you 85,300,000 mcg. Then, you multiply this by the dosage rate, which is 10 mcg/kg/min, resulting in 853,000 mcg/min. Since the pharmacy provides dopamine 800 mg in 250 mL, you convert 800 mg to micrograms (800,000 mcg) to find out how many micrograms are in each mL. This is done by dividing 800,000 mcg by 250 mL, giving you 3200 mcg/mL. Finally, to find out the mL/hr, you divide the required micrograms per minute (853,000 mcg/min) by the concentration of the solution (3200 mcg/mL), which equals approximately 266.56 mL/min. To convert this to mL/hr, multiply by 60, resulting in approximately 15,994 mL/hr. Rounding to the nearest whole number, you would set the infusion pump to 15,994 mL/hr.
