A nurse is reviewing a list of current medications for a client who is starting therapy with furosemide. Which of the following medications should the nurse identify as being contraindicated?

Lithium carbonate

Albuterol

Levothyroxine

Cetirizine

Answer and Explanation

The Correct Answer is A

A.   Furosemide can decrease the renal clearance of lithium, leading to increased lithium levels in the blood. This can potentiate the toxic effects of lithium, such as neurotoxicity and cardiac toxicity. Therefore, concurrent use of furosemide and lithium is generally contraindicated, and caution is advised. The nurse should identify lithium carbonate as contraindicated in this scenario.
B.   Albuterol is a bronchodilator commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are no significant contraindications between albuterol and furosemide.
C.   Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. There are no significant contraindications between levothyroxine and furosemide.
D.   Cetirizine is an antihistamine used to treat allergies and allergic reactions. There are no significant contraindications between cetirizine and furosemide. They are generally considered safe to use together.

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.

Correct Answer is ["1.2"]

Explanation

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
