The physician has ordered Amoxicillin 25mg/kg/day in 2 equally divided doses for a client weighing 70 kilograms. The supply of Amoxicillin is 125mg/5ml.

Calculate the correct dosage for one dose in milliliters. Round to the nearest whole number.

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

Answer and Explanation

The Correct Answer is ["35 "]

Step 1 is to calculate the total daily dosage in milligrams. This is done by multiplying the weight of the client by the ordered daily dosage. So, 70 kg × 25 mg/kg = 1750 mg/day.

Step 2 is to divide the total daily dosage by the number of doses per day to get the dosage per dose. So, 1750 mg ÷ 2 = 875 mg/dose.

Step 3 is to calculate the volume of the dose in milliliters. The supply of Amoxicillin is 125 mg/5 mL, which means there are 125 mg of Amoxicillin in every 5 mL. So, to find out how many milliliters contain 875 mg, we set up a proportion: (125 mg / 5 mL) = (875 mg / x mL). Solving for x gives x = (875 mg × 5 mL) ÷ 125 mg = 35 mL. Therefore, the correct dosage for one dose is 35 mL.

Correct Answer is C

Explanation

Choice C rationale
Dimming the lights and reducing stimulation can be an effective nursing intervention for a patient with herpes simplex virus encephalitis who is complaining of a headache. Bright lights and excessive noise can exacerbate headaches, so creating a quiet, dimly lit environment can help to alleviate this symptom.
Choice A rationale

While administering hydromorphone as needed can help to manage the patient’s pain, it does not directly address the patient’s complaint of a headache. Moreover, opioids like hydromorphone can have side effects such as drowsiness and constipation, which may not be desirable in a patient with encephalitis.
Choice B rationale
Distracting the patient with activity may not be appropriate for a patient with herpes simplex virus encephalitis who is complaining of a headache. Rest and quiet are often more beneficial for these patients.
Choice D rationale
Initiating a patient-controlled analgesia (PCA) of morphine sulfate can provide effective pain relief for some patients, but it may not be the best first-line approach for a patient with a headache due to herpes simplex virus encephalitis. Like hydromorphone, morphine can have side effects such as drowsiness and constipation.

A. Have the patient lie flat for 6 hours. B. Have the patient lie in a semi-Fowler’s position with the head of the bed at 35 degrees. C. Early ambulation. D. Have the patient lie flat for 1 hour, then sit up for 1 hour before ambulating.

Correct Answer is A

Explanation

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.
