A nurse is preparing to administer 40 mg of famotidine PO at bedtime.
If the available famotidine is 20 mg/tablet, how many tablets should the nurse administer?
The Correct Answer is ["2"]
The nurse should administer 2 tablets of famotidine. Here’s the calculation: Step 1: The total dosage required is 40 mg.
Step 2: Each tablet contains 20 mg of famotidine.
Step 3: So, the number of tablets required is 40 mg ÷ 20 mg/tablet = 2 tablets.

Correct Answer is ["0.7 "]
Explanation
Step 1 is to calculate the volume of midazolam to administer. Given that the available midazolam is 5 mg/mL and the nurse needs to administer 0.07 mg/kg to a patient who weighs 50 kg, the calculation is as follows: (0.07 mg/kg × 50 kg) ÷ 5 mg/mL = 0.7 mL3
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.
