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.)
0.5 mL.
0.600 mL.
0.6 mL.
0.8 mL.
The Correct Answer is C
First, convert the client’s weight from pounds to kilograms: 121 lb /.2 = 55 kg. Then, calculate the dose in mg: 1 mg/kg * 55 kg = 55 mg.
Finally, use the ratio of available enoxaparin to calculate the volume to administer: (55 mg / 60 mg) * 0.6 mL = 0.55 mL.
Rounded to the nearest tenth, this is 0.6 mL.
Choice A is wrong because it is less than the calculated dose of 0.6 mL.
Choice B is wrong because it is equal to the calculated dose of 0.6 mL but not rounded to the nearest tenth.
Choice D is wrong because it is greater than the calculated dose of 0.6 mL.

Correct Answer is A
Explanation
Total parenteral nutrition (TPN) is a method of administration of essential nutrients to the body through a central vein.
TPN solutions are customized for each client’s needs, including the exact amount of calories and nutrients necessary for total nutritional needs.
Monitoring the client’s weight daily is important to determine if nutritional goals are being met and to assess fluid volume status.
Choice B is wrong because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so they require a central venous catheter and should not be hung to gravity to infuse.
Choice C is wrong because TPN solution should not be titrated to blood pressure.
Choice D is wrong because the client’s blood glucose level should be monitored more frequently than weekly when receiving TPN.
Correct Answer is C
Explanation
The correct answer is C. "I should stay upright for at least 15 minutes after taking this medication."
Choice A rationale:
Black stools are a common side effect of iron supplements and do not usually require notification of the provider unless accompanied by other symptoms such as pain or gastrointestinal bleeding.
Choice B rationale:
Iron supplements should not be taken with milk because calcium can interfere with the absorption of iron, reducing its effectiveness.
Choice C rationale:
Staying upright for at least 15 minutes after taking ferrous gluconate helps prevent the risk of esophageal irritation or discomfort, which indicates the client's correct understanding of this key instruction.
Choice D rationale:
Taking an antacid with ferrous gluconate is not recommended because antacids can interfere with the absorption of iron, reducing its efficacy.
Choice E rationale:
This is the same as Choice D and also incorrect for the same reason regarding the interaction between antacids and iron absorption.
