A nurse is preparing to administer tobramycin 4 mg/kg/day IM divided in three equal doses to a client who weighs 60 kg. If the available tobramycin is 40 mg/mL, how many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["2 "]

Step 1: Calculate the total daily dose of tobramycin. The doctor ordered 4 mg/kg/day, so 4 mg/kg/day × 60 kg = 240 mg/day.

Step 2: Divide the total daily dose into three equal doses, as it is to be given in three divided doses. So, 240 mg/day ÷ 3 = 80 mg/dose.

Step 3: Calculate the volume of tobramycin to administer per dose. The available tobramycin is 40 mg/mL, so 80 mg ÷ 40 mg/mL = 2 mL. The nurse should administer 2 mL of tobramycin per dose.

Correct Answer is ["1000 "]

Explanation

Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.

So, the correct answer is 1000 mL/hr.

A. Eats a vegetarian diet with cheese 2 to 3 times a day. B. Jogs more frequently than usual daily routine. C. Drinks several bottles of carbonated water daily. D. Experiences additional stress since adopting a child.

Correct Answer is C

Explanation

Choice A rationale

A vegetarian diet with cheese 2 to 3 times a day does not significantly increase the risk of kidney stones. While dairy products do contain calcium, which can contribute to stone formation, they also contain other compounds that help prevent stones. Furthermore, a vegetarian diet is typically high in fiber, which can also help prevent stone formation.

Choice B rationale

Jogging more frequently than usual daily routine does not increase the risk of kidney stones. In fact, regular exercise can help prevent kidney stones by keeping the urinary tract healthy and promoting regular urination.

Choice C rationale

Drinking several bottles of carbonated water daily can increase the risk of kidney stones. Carbonated water contains phosphoric acid, which can increase the acidity of the urine. This can promote the formation of kidney stones, especially in individuals who are already at risk.

Choice D rationale

Experiencing additional stress since adopting a child does not directly increase the risk of kidney stones. While stress can have many negative effects on health, there is no direct link between stress and kidney stone formation.
