Question

A nurse is caring for a client who has a prescription for famotidine 160 mg PO every 6 hr. Available is famotidine oral suspension 40 mg/5 ml. How

many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a
trailing zero.)

Answer 1

The nurse should administer 20 mL of famotidine oral suspension per dose to provide the required 160 mg.

Step-by-step explanation:

The question pertains to dosage calculation, a common type of problem in the field of nursing and pharmacology. To find the volume of famotidine oral suspension that needs to be administered, we use the following proportion:

The dosage required is 160 mg and the concentration available is 40 mg/5 mL. Setting up the proportion we get:

(40 mg) / (5 mL) = (160 mg) / (x mL)

To find x, we cross multiply and solve for x:

40 mg x /* x mL = 160 mg * 5 mL

x = (160 mg * 5 mL) / (40 mg)

x = 800 mL / 40 mg

x = 20 mL

Thus, the nurse should administer 20 mL of famotidine oral suspension per dose.

Remember to not use a trailing zero and use a leading zero if it applies (e.g., 0.5 instead of .5), but in this case, 20 does not require a leading zero and should not be written as 20.0.
