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 A

Explanation

A. Slurred speech can be a symptom of lithium toxicity. As lithium levels rise in the blood, it can affect neurological function, leading to symptoms such as confusion, drowsiness, tremors, and slurred speech.
B. Stooped posture is not typically associated with lithium toxicity. It is more commonly associated with musculoskeletal issues or neurological disorders rather than lithium toxicity.
C. Elevated blood pressure is not a typical symptom of lithium toxicity. Lithium can actually have a protective effect on blood pressure, and hypertension is not commonly associated with lithium toxicity.
D. Dry cough is not a symptom of lithium toxicity. It is more commonly associated with respiratory conditions or medication side effects rather than lithium toxicity.

A. Mix the medications in a 3-mL syringe. B. Inject air into the regular vial first. C. Administer the medications in two separate syringes. D. Withdraw the NPH insulin last.

Correct Answer is D

Explanation

D. Drawing the NPH last ensures that it does not contaminate the short acting insulin. The regular insulin should be drawn first.
A. Regular and NPH insulin should not be mixed together in a single syringe prior to administration. Mixing them could alter their action profiles and affect their effectiveness.
B. While injecting air into the vial before withdrawing medication helps prevent negative pressure and facilitates easy withdrawal of the medication, it should be done for each vial individually, not specifically for the regular insulin vial.
C. The medication should be drawn up into the same syringe before administration to the patient.
