A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.2"]

Toddler's weight: 26.4 lb

1 lb = 0.453592 kg (conversion factor)

Weight in kilograms = 26.4 lb × 0.453592 kg/lb ≈ 11.979 kg

Calculate the total dosage based on the toddler's weight:

Total dosage = 10 mg/kg × 11.979 kg

≈ 119.79 mg

Determine the volume of acetaminophen solution needed based on the concentration provided: Available concentration: 80 mg/0.8 mL

Dosage required: 119.79 mgUsing the formula:

Volume (mL) = Dosage required (mg) / Concentration (mg/mL)

= 119.79 mg / 80 mg/0.8 mL

≈ 1.2 mL

Correct Answer is B

Explanation

A. There is no need for change of antibiotic as there is no cross-rectivity between macrolides and penicillins.
B. Given the client's severe allergy to penicillin, it would be safe to administer erythromycin, a macrolide, as there is no risk of cross-reactivity.
C. Diphenhydramine is an antihistamine commonly used to treat allergic reactions, but premedicating the client with diphenhydramine is not necessary.
D. Changing the route of administration would not alter the risk of an allergic reaction.

A. Female clients must have a negative mammogram prior to beginning therapy. B. Clients must have a Papanicolaou test every 6 months during treatment. C. Clients must begin a daily supplement of vitamin A for 1 month prior to initiating therapy. D. Sexually active female clients must use two forms of birth control during treatment.

Correct Answer is D

Explanation

D. One of the primary requirements of the iPledge program for sexually active females of childbearing potential is the use of two forms of contraception simultaneously, beginning one month before starting isotretinoin therapy, throughout therapy, and for one month after discontinuation of therapy. This is to ensure effective contraception and prevent pregnancy due to the teratogenic effects of isotretinoin.
A. While mammograms are important screening tests for breast cancer, they are not a requirement of the iPledge program for female clients receiving isotretinoin.
B. Papanicolaou (Pap) tests, which screen for cervical cancer, are not a requirement of the iPledge program. However, sexually active females of childbearing potential must have monthly pregnancy tests and must agree to use two forms of contraception simultaneously during isotretinoin therapy.
C. There is no requirement for clients to take a daily supplement of vitamin A prior to initiating isotretinoin therapy as part of the iPledge program.
