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.)
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 D
Explanation
Choice A rationale: TPN cannot be administered subcutaneously due to its composition.
Choice B rationale: Intraosseous access is for emergency situations when IV access isn't attainable.
Choice C rationale: A midline catheter might not be suitable for the hypertonic nature of TPN and can lead to complications.
Choice D rationale: Total parenteral nutrition (TPN) is a hypertonic solution that requires infusion into a large vein. The central venous access device allows for high-flow rates and avoids irritation or damage to smaller peripheral veins.
Correct Answer is A
Explanation
Choice A rationale: Dopamine is administered in septic shock to increase blood pressure. If the client continues to exhibit hypotension, increasing the rate of infusion may be necessary to achieve the desired therapeutic effect.
Choice B rationale: Chest pain might indicate other issues but might not directly relate to the need for increasing the dopamine infusion rate.
Choice C: Extravasation is a complication of IV therapy but doesn’t necessarily warrant an increase in the dopamine infusion rate.
Choice D rationale: Headache might occur due to various reasons but might not solely indicate the need to increase the dopamine infusion rate.
