A prefilled syringe of Lovenox should be purged slightly before administering the drug because:

A.

doing so ensures more accurate dosing.

B.

doing so ensures needle patency.

C.

the cartridge won't work otherwise.

D.

the syringe may (and usually does) contain air.

Answer and Explanation

The Correct Answer is D

A. Doing so ensures more accurate dosing: Prefilled Lovenox (enoxaparin) syringes are designed not to be purged. The medication is pre-measured, and removing any amount-even a tiny bit-will alter the dose. Therefore, accuracy is maintained by not expelling anything.

B. Doing so ensures needle patency: The needle is already patent (open). Purging is not required for this.

C. The cartridge won't work otherwise: The mechanics of the syringe work regardless of the air bubble.

D. The syringe may (and usually does) contain air: Lovenox prefilled syringes intentionally contain a small air bubble, and you should not purge it. The air bubble acts as an air-lock technique, ensuring the full dose is delivered and preventing medication leakage from the subcutaneous site, which reduces bruising.

Correct Answer is ["1140"]

Explanation

First, convert all household/US Customary units to milliliters (mL) using the following standard conversions:

  • 1 oz = 30 mL
  • 1 cup = 240 mL
  1. Clear Soda:4 oz × 30 mL/oz = 120 mL
  2. Toast:0 mL(Solid food is not counted as fluid intake for I&O)
  3. Water:12 oz × 30 mL/oz = 360 mL
  4. Fruit-flavored Gelatin:1 cup ×× 240 mL/cup = 240 mL (Gelatin melts at body temperature and is counted as fluid intake)
  5. Chicken Broth:1/2 cup × 240 mL/cup = 120 mL
  6. IV Fluid (0.9% Sodium Chloride):300 mL

Total Intake (mL) = (120 mL) + (0 mL) + (360 mL) + (240 mL) + (120 mL) + (300 mL)

Total Intake (mL) = 1,140 mL

Correct Answer is D

Explanation

Step 1: Convert the ordered dose to mg

  • Ordered dose = 0.05 g.
  • 1 g = 1000 mg.
  • 0.05 g = 50 mg.

Step 2: Compare with available tablet strength

  • Each tablet contains 50 mg.
  • Ordered dose = 50 mg.
  • Therefore, the patient needs 1 tablet.
