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 ["2.4"]
Explanation
Rationale:
To calculate the dosage of Nitroprusside in mcg/min, first convert the client's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. Therefore, 176 lbs is approximately 80 kg. Next, multiply the client's weight in kg by the dosage rate: 0.5 mcg/kg/min. So, 80 kg * 0.5 mcg/kg/min equals 40 mcg/min. To find mcg/hr, multiply the mcg/min dosage by 60, the number of minutes in an hour, which gives us 2400 mcg/hr. Finally, to calculate mL/hr, use the concentration of the drug: 500 mg in 500 mL. Since 1 mg equals 1000 mcg, 500 mg is 500,000 mcg. Divide the hourly dosage in mcg by the total number of mcg in the available fluid to find the mL/hr. Thus, 2400 mcg/hr divided by (500,000 mcg / 500 mL) results in 2.4 mL/hr. Rounded to the nearest tenth, the final dosages are 40 mcg/min, 2400 mcg/hr, and 2.4 mL/hr.
