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.

Answer and Explanation

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 C

Explanation

The nurse should instruct the client to administer the medication through clothing if necessary.

In an emergency, an epinephrine auto-injector can be given through clothing.
Choice A is wrong because massaging the site after injection is not mentioned as something to avoid in the instructions for using an epinephrine auto-injector.
Choice B is wrong because the medication should be injected into the outer thigh, not the abdomen.
Choice D is wrong because aspiration prior to administration of the medication is not mentioned as a necessary step in the instructions for using an epinephrine auto-injector.

A. Weight gain. B. Oliguria. C. Headaches. D. Nausea.

Correct Answer is B

Explanation

Osmotic laxatives work by drawing water into the intestines, which can lead to fluid loss and dehydration if not enough fluids are consumed.

Oliguria, or decreased urine output, can be a sign of fluid volume deficit and dehydration.

Choice A is wrong because Weight gain, is not an indication of fluid volume deficit as weight loss is more commonly associated with dehydration.

Choice C is wrong because Headaches, can be a symptom of dehydration but is not specific to fluid volume deficit.

Choice D is wrong because Nausea, can also be a symptom of dehydration but is not specific to fluid volume deficit.
