A child who weighs 55 lb receives a prescription for cefotaxime 150 mg/kg/day IV in divided doses every 6 hours. How many mg should the nurse administer each day?
(Enter numerical value only.)
The Correct Answer is ["3750"]
Convert the weight to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs approximately 25 kilograms (55 ÷ 2.2). Then, multiply the weight in kilograms by the prescribed amount of medication, which is 150 mg/kg/day.
So, 25 kg × 150 mg/kg/day equals 3750 mg/day.

Correct Answer is A
Explanation
Rationale
A. This action helps maintain adequate cerebral perfusion pressure and venous drainage, which is important in suspected stroke cases. It supports optimal cerebral blood flow and reduces the risk of increased intracranial pressure. However, it's not the immediate intervention required for this client. The primary focus initially is on diagnostic evaluation and stabilization.
B. Elevating the joints on the affected side can help reduce dependent edema and promote circulation. This intervention is part of ongoing nursing care to prevent complications like deep vein thrombosis (DVT) in stroke patients who may have reduced mobility. While important, it is not the immediate priority in the acute phase of management.
C. Gathering a focused history is crucial to understanding potential causes or exacerbating factors contributing to the client's symptoms While important, it is not the immediate priority in the acute phase of management.
D. Intermittent pneumatic compression devices (IPC) are used to prevent deep vein thrombosis (DVT) by enhancing venous return and preventing stasis in the lower extremities. While DVT prevention is important in stroke patients, it is not the immediate intervention required for the client's acute neurological symptoms.
Correct Answer is D
Explanation
Rationale
A. Herpes simplex virus type II (HSV-II) primarily spreads through direct contact with the lesions and is not airborne. Airborne precautions and negative airflow rooms are not necessary for this condition.
B. Scarlet fever is caused by Group A Streptococcus bacteria and typically spreads through respiratory droplets. However, scarlet fever itself does not require airborne precautions. If complicated with pneumonia, respiratory droplets could potentially spread the infection, but specific airborne precautions are generally not required unless there are other pathogens involved that require it.
C. Scabies is caused by the Sarcoptes scabiei mite and spreads through direct skin-to-skin contact. It does not require airborne precautions or negative airflow rooms.
D. Apositive Mantoux test and sputum cultures positive for acid-fast bacillus (AFB) suggest tuberculosis (TB) infection. TB is spread through airborne droplets (e.g., coughing, sneezing), and therefore, requires airborne precautions including negative airflow rooms to prevent transmission to others.A
