Question 1:

A nurse is preparing to administer docusate sodium PO to a postpartum client who has a prescription for 200 mg/day in two equally divided doses. The client states she has trouble swallowing tablets and capsules. Therefore, the nurse has obtained docusate sodium liquid 50 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it

Answer and Explanation
Correct Answer: "10ml" mL

Explanation

The question is asking for the amount of docusate sodium liquid the nurse should administer per dose. The prescription is for 200 mg/day in two equally divided doses, and the liquid form of the medication is 50 mg/5 mL.

Step 1 is to determine the amount of medication needed per dose. Since the total daily dose is 200 mg and it’s divided into two doses, each dose will be 200 mg ÷ 2 = 100 mg.

Step 2 is to convert this dose from mg to mL using the concentration of the liquid medication. The concentration is 50 mg/5 mL, which means that 1 mL contains 50 mg ÷ 5 = 10 mg of the medication.

Step 3 is to calculate the volume of the medication needed for a 100 mg dose. Since 1 mL contains 10 mg, we need 100 mg ÷ 10 mg/mL = 10 mL.

So, the nurse should administer 10 mL of docusate sodium liquid per dose.

Question 2:

A nurse is preparing to administer enoxaparin 55 mg subcutaneous to a client who has a deep-vein thrombosis after undergoing a cesarean birth. Available is enoxaparin solution for injection 60 mg/0.6 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "0.6 mL" mL

Explanation

60mg=0.6

55mg= 55*0.6/60

Volume (mL) = 0.55 mL

Rounding to the nearest tenth, the nurse should administer 0.6 mL of enoxaparin solution to the client.

Question 3:

A nurse prepares to administer 0.9% sodium chloride 200 mL over 30 min. The nurse should set the IV infusion pump to administer how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "400" mls/hr

Explanation

Infusion rate (mL/hr) = 200 mL / 0.5 hr Infusion rate (mL/hr) = (200 mL/hr) *2

= 400mls/hr

Question 5:

A nurse is preparing to administer enoxaparin 55 mg subcutaneously to a client who has a deep-vein thrombosis after undergoing a cesarean birth. Available is enoxaparin solution for injection 60 mg/0.6 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "0.6" mL

Explanation

Step 1: Determine the amount of enoxaparin in mg per mL. 60 mg ÷ 0.6 mL = 100 mg/mL

Result: 100 mg/mL

Step 2: Calculate the volume in mL needed to administer 55 mg. 55 mg ÷ 100 mg/mL = 0.55 mL

Result: 0.55 mL

Step 3: Round the result to the nearest tenth. 0.55 mL rounded to the nearest tenth = 0.6 mL

Result: 0.6 mL

The nurse should administer 0.6 mL of enoxaparin.

Question 6:

A nurse is reviewing a new prescription for propranolol 200 mg PO daily divided in equal doses every 12 hr for a client who has migraine headaches during the premenstrual period. Available is propranolol solution 4 mg/mL. How many mL should the client self-administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "25 mL" mL

Explanation

mL = mg / 4 mL = 100 / 4

mL = 25 / 1

This means that the client needs to take 25 mL of the propranolol solution every 12 hours to get the prescribed dose of 200 mg per day

Question 10:

A nurse is caring for an infant. The mother states the infant took 2.5 oz of formula at the last feeding. How many mL should the nurse document as the intake on the 1&O record? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "75" mls

Explanation

Step 1: Identify the amount of formula in ounces. Result: 2.5 oz

Step 2: Convert ounces to milliliters using the conversion factor 1 ounce = 30 mL. Calculation: 2.5 oz × 30 mL/oz Result: 2.5 × 30 = 75 mL

Step 3: Round the result to the nearest whole number. Result: 75 mL (no rounding needed)

The nurse should document 75 mL as the intake on the I&O record.
