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 ["22.6"]
Explanation
To calculate the IV pump setting, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The client weighs 166 pounds, which is approximately 75.45 kilograms. Next, calculate the dosage in units per hour by multiplying the client's weight in kilograms by the ordered dosage of 15 units/kg/hr, which equals 1131.75 units/hr. Since Heparin is available as 25,000 units in 500 ml, divide the total units in the bag by the volume to find the concentration, which is 50 units/ml. Finally, divide the dosage required per hour by the concentration to find the volume to be administered per hour. Therefore, the IV pump should be set to approximately 22.6 ml/hr, rounding to the nearest tenth.
