A client who weighs 160 pounds receives a prescription for gentamicin 5 mg/kg/day IV in divided doses every 8 hours. How many mg should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["121"]

Calculation Steps:

Step 1: Convert weight from pounds to kilograms: 160 pounds ÷ 2.2 = 72.7 kg. Result = 72.7 kg.

Step 2: Calculate the total daily dose: 5 mg/kg/day × 72.7 kg = 363.5 mg/day. Result = 363.5 mg/day.

Step 3: Calculate the dose per administration: 363.5 mg/day ÷ 3 doses/day = 121.2 mg/dose. Result = 121.2 mg/dose.

Step 4: Round to the nearest whole number: 121.2 mg ≈ 121 mg.

Result = 121 mg.

Correct Answer is B

Explanation

Choice A reason: Exenatide should be administered within 60 minutes before the morning and evening meals, not within 30 minutes before or after a meal.

Choice B reason: Notifying the healthcare provider if abdominal pain occurs is important because exenatide can cause pancreatitis, and abdominal pain may be a symptom of this condition.

Choice C reason: Exenatide does not act in the same way as insulin. It is an incretin mimetic that enhances glucose-dependent insulin secretion, among other actions.

Choice D reason: There are precautions when taking exenatide with other medications, especially those that affect blood glucose levels, so this statement is incorrect.

A. Continue with the blood pressure assessment. B. Note the presence of an auscultatory gap. C. Reposition the stethoscope over the brachial artery. D. Reinflate the cuff to a higher number.

Correct Answer is A

Explanation

Choice A reason: When inflating and deflating the cuff, it is normal to first hear silence, followed by the first Korotkoff sound (a clear tapping). That first sound marks the systolic blood pressure. The nurse should continue deflating the cuff and listening until the sounds disappear, which indicates the diastolic pressure.

Choice B reason: A gap is a temporary disappearance of sounds after they have started, not before.

Choice C reason: Repositioning the stethoscope may not address the issue of the auscultatory gap and may lead to inaccurate readings.

Choice D reason: Re-inflating the cuff to a higher number is unnecessary and may cause discomfort without addressing the auscultatory gap.
