A nurse is preparing to administer heparin 10,000 units subcutaneously every 8 hours. The available heparin injection is 20,000 units/mL. How many milliliters 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 ["0.5"]

To calculate the required mL of heparin injection per dose, we need to use the following formula: mL = (units per dose) ÷ (units per mL)

Substituting the given values in the formula, we get:

mL = (10,000 units) ÷ (20,000 units/mL) mL = 0.5 mL

Correct Answer is ["2 mL"]

Explanation

To calculate the volume to be administered, the nurse should divide the prescribed dose (200 mg) by the

concentration of the available medication (300 mg/3 mL): 200 mg / (300 mg/3 mL) = 2 mL.

A. Take the medication at 1800, 30 min after the evening meal. B. Over-the-counter oral preparations can be taken with this medication. C. Choose the same day of each week to take this medication. D. The client can return to bed after taking the medication, but before eating.

Correct Answer is C

Explanation

c) Choose the same day of each week to take this medication.

The nurse should interpret the prescription for alendronate 70 mg PO once per week upon waking to be taken 30 min before food, ﬂuids, or medication with a client who has osteoporosis as instructing the client to choose the same day of each week to take the medication. This will help to ensure that the medication is taken consistently and at the appropriate time.

Taking the medication at 1800, 30 min after the evening meal (option A) is not consistent with the prescription, which specifies that the medication should be taken upon waking and before food, ﬂuids, or other medications. Over-the-counter oral preparations can be taken with this medication (option B) is not accurate; the prescription specifies that alendronate should be taken 30 min before other medications. The client can return to bed after taking the medication, but before eating (option D) is not consistent with the prescription, which specifies that the client should remain upright for 30 min after administration.

The correct answer is c. Choose the same day of each week to take this medication.

Rationale for each choice:

Choice a. Take the medication at 1800, 30 min after the evening meal. is incorrect.

Statement:The prescription specifies that the medication should be taken upon waking,30 minutes before any food,fluids,or other medications.Taking it at 1800,30 minutes after the evening meal,would not meet these requirements.

Choice b. Over-the-counter oral preparations can be taken with this medication. is incorrect.

Statement:The prescription states that alendronate should be taken 30 minutes before any other medications.This includes over-the-counter oral preparations,as they could potentially interfere with the absorption of alendronate.

Choice d. The client can return to bed after taking the medication, but before eating. is incorrect.

Statement:The prescription instructs the client to remain upright for 30 minutes after taking alendronate.This is because lying down can increase the risk of the medication irritating the esophagus.

Choice c. Choose the same day of each week to take this medication. is the correct interpretation of the prescription.

Statement:Alendronate is typically taken once a week to maintain consistent levels in the body and effectively treat osteoporosis.Choosing the same day each week helps ensure that the medication is taken regularly and consistently.
