The client also received 300 mL of 0.9% sodium chloride IV. The nurse should record how many mL of intake on the client's record? (Round the answer to the nearest whole number.)
Explanation
Convert each intake to mL:
4 oz clear soda = 4 × 30 = 120 mL
12 oz water = 12 × 30 = 360 mL
1 cup fruit-flavored gelatin = 1 × 240 = 240 mL
1/2 cup chicken broth = 0.5 × 240 = 120 mL
300 mL IV fluid (0.9% sodium chloride) = 300 mL
Now add all liquid intakes:
120 + 360 + 240 + 120 + 300 = 1,140 mL
Answer: 1,140 mL
A nurse is preparing to administer amoxicillin 300 mg PO. The amount available is amoxicillin oral solution 250 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step 1: Identify what is given
Prescribed dose: 300 mg
Available concentration: 250 mg per 5 mL
Step 2: Set up a proportion
250 mg : 5 mL = 300 mg : x mL
Step 3: Solve for x
x = (300 × 5) ÷ 250
x = 1500 ÷ 250
x = 6
Final Answer:
The nurse should administer 6 mL of amoxicillin
A nurse is preparing to administer amoxicillin 500 mg PO. Available is amoxicillin 250 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step 1: Identify what is given
Prescribed dose: 500 mg
Available tablet strength: 250 mg per tablet
Step 2: Use the formula
Number of tablets = Prescribed dose ÷ Dose per tablet
Number of tablets = 500 ÷ 250 = 2
Final Answer:
The nurse should administer 2 tablets of amoxicillin.

A nurse is preparing to administer morphine 15 mg subcutaneously. The amount available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step 1: Identify what is given
Prescribed dose: 15 mg
Available concentration: 10 mg/mL
Step 2: Use the formula
Volume (mL) = Prescribed dose ÷ Concentration
Volume = 15 ÷ 10 = 1.5 mL
Final Answer:
The nurse should administer 1.5 mL of morphine.
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/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.
Explanation
Step 1: Identify what is given
Prescribed dose: 3 mg
Available concentration: 5 mg/mL
Step 2: Use the formula
Volume (mL) = Prescribed dose ÷ Concentration
Volume = 3 ÷ 5 = 0.6 mL
Final Answer:
The nurse should administer 0.6 mL of diazepam.
A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step 1: Identify what is given
Prescribed dose: 5 mg
Available concentration: 50 mg/mL
Step 2: Use the formula
Volume (mL) = Prescribed dose ÷ Concentration
Volume = 5 ÷ 50 = 0.1 mL
Final Answer:
The nurse should administer 0.1 mL of haloperidol.

Prescribed dose: 0.0625 mg
Available tablet strength: 0.125 mg per tablet
Step 2: Use the formula
Number of tablets = Prescribed dose ÷ Tablet strength
Number of tablets = 0.0625 ÷ 0.125 = 0.5
