A nurse is preparing to administer 40 mg of furosemide intravenously.

The available furosemide is 10 mg/1 mL. How many mL should the nurse administer per dose? Round the answer to the nearest whole number.

Use a leading zero if it applies. Do not use a trailing zero.

Choice A rationale
While tremors and decreased mobility are common symptoms of Parkinson’s disease, they are not the most significant impact on a patient’s life. These physical symptoms can be managed with medication and physical therapy.
Choice B rationale
Loss of independence is often the most significant impact on a patient’s life. As the disease progresses, patients may find it increasingly difficult to perform daily activities and may require assistance.

Choice C rationale
Age-related changes can contribute to the progression of Parkinson’s disease, but they are not the most significant impact on a patient’s life. The disease itself, rather than aging, is the primary cause of the symptoms.
Choice D rationale
Neurologic deficits are a result of Parkinson’s disease, but they are not the most significant impact on a patient’s life. The loss of independence that results from these deficits is often more impactful.

Choice A rationale
After a lumbar puncture, it is important for the patient to lie flat for approximately 6 hours. This position helps to prevent headaches that can occur after the procedure, which are caused by leakage of cerebrospinal fluid at the needle puncture site. Lying flat allows the puncture site to seal and prevents the leakage of cerebrospinal fluid.
Choice B rationale
Having the patient lie in a semi-Fowler’s position with the head of the bed at 35 degrees is not typically recommended immediately after a lumbar puncture. This position could potentially increase the risk of a post-lumbar puncture headache.
Choice C rationale
Early ambulation is not recommended after a lumbar puncture. Moving around too soon after the procedure can increase the risk of a headache and may also increase the risk of complications at the puncture site.
Choice D rationale
Having the patient lie flat for 1 hour, then sit up for 1 hour before ambulating is not a typical recommendation after a lumbar puncture. The standard recommendation is to have the patient lie flat for approximately 6 hours to reduce the risk of complications.
