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
Given:
Prescribed dose: 10 mg of oxycodone per dose
Available tablets: 5 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 5 mg tablets are needed to make 10 mg of oxycodone.
Set up a proportion to solve for the unknown number of tablets (X):
5 mg/tablet = 10 mg/X tablets
Cross-multiplying gives us:
5 mg x X tablets = 10 mg x 1 tablet
Simplifying:
5X = 10
Solving for X:
X = 10 / 5 = 2 tablets
A nurse is preparing to administer 0.9% sodium chloride 000 mL IV to infuse over 5 hr to a client who is postoperative following a cesarean birth. The nurse should set the IV pump to deliver 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.)
Explanation
Given:
Total volume: 1000 mL
Time: 5 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1000 mL/5 hr = X mL/1 hr
Cross-multiplying gives us:
1000 mL x 1 hr = 5 hr x X mL
Simplifying:
1000 = 5X
Solving for X:
X = 1000 / 5 = 200 mL/hr
A nurse is assisting with the care of a client who is pregnant and has a prescription for dextrose 5% in 0.9% sodium chloride 250 mL IV to infuse over 4 hr. The nurse should ensure that the IV pump is set 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.)
Explanation
Given:
Total volume: 250 mL
Time: 4 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
250 mL/4 hr = X mL/1 hr
Cross-multiplying gives us:
250 mL x 1 hr = 4 hr x X mL
Simplifying:
250 = 4X
Solving for X:
X = 250 / 4 = 62.5 mL/hr
Round to the nearest whole number:
63 mL/hr.
A nurse is preparing to administer lactated Ringer's 1,500 mL IV to infuse over 8 hr to a pregnant client who has gastroenteritis. The nurse should set the IV pump to deliver 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.)
Explanation
Given:
Total volume: 1500 mL
Time: 8 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1500 mL/8 hr = X mL/1 hr
Cross-multiplying gives us:
1500 mL x 1 hr = 8 hr x X mL
Simplifying:
1500 = 8X
Solving for X:
X = 1500 / 8 = 187.5 mL/hr
Round to the nearest whole number:
188 mL/hr.
A nurse is preparing to administer potassium chloride 30 mEq PO every 12 hr. Available are potassium chloride 10 mEq sustained-release tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Given:
Prescribed dose: 30 mEq of potassium chloride per dose
Available tablets: 10 mEq tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 10 mEq tablets are needed to make 30 mEq of potassium chloride.
Set up a proportion to solve for the unknown number of tablets (X):
10 mEq/tablet = 30 mEq/X tablets
Cross-multiplying gives us:
10 mEq x X tablets = 30 mEq x 1 tablet
Simplifying:
10X = 30
Solving for X:
X = 30 / 10 = 3 tablets
A nurse is reviewing a new prescription for propranolol 20 mg PO four times daily for a client who has premenstrual migraine headaches. Available is propranolol solution 4 mg/mL. The nurse should recognize that the client should take how many mL per dose? (Round the answer to the nearest whole number. Use a leading zero If it applies. Do not use a trailing zero.)
Explanation
Given:
Prescribed dose: 20 mg of propranolol per dose
Available concentration: 4 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
4 mg/mL = 20 mg/X mL
Cross-multiplying gives us:
4 mg x X mL = 20 mg x 1 mL
Simplifying:
4X = 20
Solving for X:
X = 20 / 4 = 5 mL
A nurse is preparing to administer heparin 5.000 units subcutaneous every 12 hr to a client who is pregnant and has atrial fibrillation. Available is heparin solution for injection 7.500 units/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Given:
Prescribed dose: 5,000 units of heparin
Available concentration: 7,500 units/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
7,500 units/mL = 5,000 units/X mL
Cross-multiplying gives us:
7,500 units x X mL = 5,000 units x 1 mL
Simplifying:
7,500X = 5,000
Solving for X:
X = 5,000 / 7,500 = 0.67 mL
A nurse is assisting with the care of a client who is in labor and is receiving penicillin G 5.000.000 units via intermittent IV bolus over 60 min. Available is penicillin G 5,000,000 units in 0.9% sodium chloride 100 mL. The nurse should ensure that the IV pump is set to deliver 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.)
Explanation
Given:
Total volume: 100 mL
Time: 60 minutes
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
100 mL/60 min = X mL/1 min
Cross-multiplying gives us:
100 mL x 1 min = 60 min x X mL
Simplifying:
100 = 60X
Solving for X:
X = 100 / 60 = 1.67 mL/min
Convert to mL/hr:
1.67 mL/min x 60 min/hr = 100 mL/hr
A nurse is preparing to administer methadone 2.5 mg PO every 8 hr to a client who is postpartum. Available is methadone oral solution 10 mg/5 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.)
Explanation
Given:
Prescribed dose: 2.5 mg of methadone per dose
Available concentration: 10 mg/5 mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
10 mg/5 mL = 2.5 mg/X mL
Cross-multiplying gives us:
10 mg x X mL = 2.5 mg x 5 mL
Simplifying:
10X = 12.5
Solving for X:
X = 12.5 / 10 = 1.25 mL
A nurse is caring for a newborn who weighs 6 lb. The nurse should record the newborn's weight as how many g? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Let's convert pounds to grams.
We know that 1 pound= 453.592 grams.
Convert 6 pounds to grams, we multiply:
6 pounds x 453.592 grams/pound = 2721.552 grams
Rounding this to the nearest whole number gives 2722 grams.
