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.)
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 C
Explanation
A. Nitroglycerin patches should not be removed for routine activities like bathing unless specifically instructed.
B. Nitroglycerin is used to treat hypertension, not induce it. Monitoring for hypertension after applying the patch is unnecessary.
C. To prevent skin irritation and tolerance to the medication, it is important to rotate the application sites when using a transdermal patch. This allows the skin to recover and helps maintain the effectiveness of the medication.
D. Nitroglycerin patches are typically worn continuously for 12 to 14 hours and then removed for a 10- to 12-hour nitrate-free interval to prevent tolerance to the medication.
Correct Answer is D
Explanation
D. Chills are a hallmark sign of febrile nonhemolytic reactions. These reactions typically present with fever, chills, and occasionally rigors (shivering). They are caused by recipient antibodies reacting to donor leukocytes or cytokines present in the transfused blood components.
A. Dyspnea (difficulty breathing) is not typically associated with febrile nonhemolytic reactions. It is more commonly seen in acute hemolytic reactions or transfusion-related acute lung injury (TRALI).
B. Urticaria (hives) is more commonly associated with allergic transfusion reactions rather than febrile nonhemolytic reactions.
C. Vomiting is not a characteristic feature of febrile nonhemolytic reactions. It may occur in some cases of transfusion reactions, but it is not specific to febrile nonhemolytic reactions.
