Elixir

B.

Solution

C.

Suspension

D.

Tincture

Answer and Explanation

The Correct Answer is C

A. Elixir: An elixir is a clear, sweetened hydroalcoholic liquid used for oral administration of medication. The drug is fully dissolved, so there are no undissolved particles present.

B. Solution: A solution is a homogeneous mixture in which the medication is completely dissolved in a solvent. It does not contain undissolved particles and remains uniform throughout.

C. Suspension: A suspension is a liquid preparation containing solid drug particles dispersed but not dissolved in a liquid. It requires shaking before administration to ensure even distribution of the medication.

D. Tincture: A tincture is an alcoholic or hydroalcoholic solution of a drug, usually for topical or oral use, with the medication fully dissolved. It does not contain undissolved particles.

Correct Answer is C

Explanation

Calculation:

  • Identify the total volume and infusion rate

Total Volume: 900 mL

Infusion Rate: 75 mL/hr

  • Calculate the time the bag will last

Time (hours) = Total Volume ÷ Infusion Rate

Time = 900 ÷ 75

= 12 hours

Correct Answer is {"dropdown-group-1":"D"}

Explanation

A. Indirectly: Infusion pumps do not control fluid delivery indirectly; they provide precise, direct control over both rate and volume. Indirect regulation would rely on manual estimation or gravity, which lacks accuracy.

B. Manually: Manual regulation involves using roller clamps or gravity drips, which are prone to error and cannot ensure consistent infusion rates. Infusion pumps are specifically designed to minimize manual adjustments.

C. Occasionally: Infusion pumps provide continuous control rather than intermittent or occasional regulation. Sporadic adjustments would defeat the purpose of automated delivery and compromise safety.

D. Automatically: Infusion pumps are engineered to automatically deliver fluids and medications at predetermined rates and volumes, ensuring accuracy and consistency. This reduces the risk of under- or over-infusion and enhances patient safety.
