A client with multiple sclerosis is prescribed Dantrolene (Dantrium) 0.1 grams PO bid for spasticity. Dantrolene is available in 100 mg capsules. How many capsules should the nurse administer? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["1"]

To calculate the number of capsules needed, we'll first convert grams to milligrams:

0.1 grams x 1000 mg/gram = 100 mg

Then, we can set up a proportion:

x capsules / 100 mg = 1 capsule / 100 mg

Cross-multiplying:

100x = 100

Solving for x:

x = 100 / 100

x = 1

Therefore, the nurse should administer 1 capsule of Dantrolene.

Explanation

Calculating the Ferrous Fumarate Dose

Problem: Administer ferrous fumarate 3 mg/kg/day PO three times daily to an 88-pound child. The available concentration is 100 mg/5 mL.

Steps:

Convert pounds to kilograms:

88 pounds x (1 kg / 2.20462 pounds) ≈ 39.9 kg

Calculate the daily dose:

3 mg/kg/day x 39.9 kg = 119.7 mg/day

Calculate the dose per administration (TID):

119.7 mg/day / 3 doses = 39.9 mg/dose

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (39.9 mg) and the concentration of the medication (100 mg/5 mL).

Proportion:

x mL / 39.9 mg = 5 mL / 100 mg

Cross-multiply:

100x = 199.5

Solve for x:

x = 199.5 / 100

x ≈ 2

Answer: The child should receive approximately 2 mL of ferrous fumarate oral suspension for each dose.

A. 1 tablet. B. 1/2 tablet. C. 2 tablets. D. 1 1/2 tablets.

Correct Answer is C

Explanation

To determine the number of tablets needed, we can set up a proportion:

x tablets / 7.5 mg = 1 tablet / 5 mg

Cross-multiplying:

5x = 7.5

Solving for x:

x = 7.5 / 5

x = 1.5

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets of metolazone.
