A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr. The client's weight is 121 lb. Available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.6"]

Calculation: 1 mg/kg dose x 121 lb (weight) = 55 kg (approximately) 55 kg x 1 mg = 55 mg (dose required) Enoxaparin 60 mg/0.6 mL = 100 mg/mL Therefore, 55 mg / 100 mg/mL =

0.55 mL (rounded to 0.6 mL).

Correct Answer is C

Explanation

Choice A rationale: This prescription indicates a single dose, which seems appropriate for its use.
Choice B rationale: Penicillin G is usually administered in divided doses 4 to 6 hours apart intramuscularly.
Choice C rationale: The nurse should clarify the prescription for warfarin with the provider before administering it. Warfarin is an anticoagulant that is usually given orally, not subcutaneously. The dose of warfarin is also measured in milligrams, not units. The nurse should verify the route, dosage, and frequency of warfarin with the provider to prevent adverse effects such as bleeding or clotting.
Choice D rationale: The frequency and dosage of Tetracycline are standard and within the typical range for treatment.

A. Calcium 8 mg/dL B. Magnesium 1.1 mEq/L C. Sodium 150 mEq/L D. Potassium 4.6 mEq/L

Correct Answer is D

Explanation

Choice A rationale: Calcium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice B rationale: Magnesium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice C rationale: Sodium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice D rationale: Sodium polystyrene sulfonate is used to lower potassium levels in conditions like hyperkalemia. A decrease in potassium levels (within normal range)
indicates effectiveness.
