Which of the following matches the term diluent?

A.

Glass container with single dose of medication

B.

Glass container with self-sealing rubber stopper

C.

Prevents aspiration of tiny glass particles

D.

Normal saline or Sterile water

Answer and Explanation

The Correct Answer is D

A. Glass container with single dose of medication: This describes an ampule. An ampule is a small, sealed glass container holding a single dose of medication (or solution). It is not a diluent itself.

B. Glass container with self-sealing rubber stopper: This describes a vial. A vial is a small bottle containing medicine, often in powder or liquid form, sealed with a rubber stopper (diaphragm) that can be repeatedly punctured for drug extraction. It is not a diluent itself.

C. Prevents aspiration of tiny glass particles: This describes the function of a filter needle when withdrawing medication from an ampule, which must be broken open, potentially creating glass shards. It is a necessary safety step, not the definition of a diluent.

D. Normal saline or Sterile water: A diluent is a liquid (like Normal Saline, Sterile Water, or a specific solvent) added to a powdered or concentrated substance to decrease its concentration or to dissolve it for administration. This process is called reconstitution.

Correct Answer is A

Explanation

The reconstituted concentration is 3 grams in 30 mL.

  • Convert to grams per mL: 3 g ÷ 30 mL = 0.1 g/mL.
  • Ordered dose is 1.5 g.
  • Volume needed = 1.5 g ÷ 0.1 g/mL = 15 mL.
  • Therefore, the nurse should administer 15 mLper dose.

Correct Answer is A

Explanation

A. 1mL:A 1-mL syringe (often a Tuberculin or TB syringe) is calibrated in hundredths of a milliliter (0.01 mL), offering the highest precision for small-volume doses like 1ml or less. This precision is essential for anticoagulants like Lovenox.

B. 3 mL:A 3-mL syringe is calibrated in tenths of a milliliter (0.1ml). While it can hold 1 mL, it is lessaccuratethan a 1-mL syringe, making it an inferior choice for a medication requiring high precision.

C. insulin U-50:Insulin syringes are calibrated in Units and are only for insulin administration. They are not used for Lovenox unless a highly specific, facility-approved protocol and conversion chart is used (which is rare).

D. insulin U-100:Similar to the U-50, this syringe is only for insulin and is not appropriate for Lovenox measured in milliliters.
