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 applies)
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.
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.)
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.
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.)
Explanation
Infusion rate (mL/hr) = 200 mL / 0.5 hr Infusion rate (mL/hr) = (200 mL/hr) *2
= 400mls/hr
1.A nurse is caring for a client who is postpartum and has a prescription for oxytocin 10 units IM one time only for the saturation of a perineal pad in 15 min or less. How should the nurse interpret this prescription?
Explanation
The correct answer is Choice B.
Choice A rationale: This is incorrect because the prescription is for one time only, not for repeated doses.Giving the medication each time the client saturates the perineal pad within 15 min could cause uterine hyperstimulation, water intoxication, or hypotension1.
Choice B rationale: This is correct because the prescription is for one time only and the indication is saturation of a perineal pad in 15 min or less.This is a sign of postpartum hemorrhage, which is a common and potentially life-threatening complication of childbirth2.Oxytocin is a uterotonic agent that helps the uterus contract and reduce bleeding3.
Choice C rationale: This is incorrect because waiting 15 min to administer the medication after the client saturates a perineal pad could result in excessive blood loss and hypovolemic shock. The medication should be given as soon as possible after the indication is met.
Choice D rationale: This is incorrect because offering the medication now to prevent saturation of perineal pad is not the intended use of the prescription. The medication is for treatment, not prevention, of postpartum hemorrhage. Prophylactic oxytocin is usually given intravenously or intramuscularly during or immediately after the delivery of the placenta.
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.)
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.
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.)
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
A nurse is caring for a client who is postpartum and has a prescription for oxytocin 10 units IM one time only for the saturation of a perineal pad in 15 min or less. How should the nurse interpret this prescription?
Explanation
Choice A reason: Giving the medication each time the client saturates the perineal pad within 15 minutes is incorrect. The prescription specifies a one-time administration of oxytocin, not repeated doses. Administering the medication multiple times could lead to an overdose and potential complications, as oxytocin is a powerful drug used to control postpartum bleeding by stimulating uterine contractions.
Choice B reason: This is the correct interpretation of the prescription. The nurse should administer the medication once if the client saturates the perineal pad within 15 minutes. This means that if the client experiences heavy bleeding that results in the saturation of a perineal pad within this timeframe, the nurse should give the prescribed dose of oxytocin intramuscularly to help control the bleeding and promote uterine contractions.
Choice C reason: Waiting 15 minutes to administer the medication after the client saturates a perineal pad is incorrect. The prescription does not indicate a delay in administration. Prompt administration of oxytocin is crucial in managing postpartum hemorrhage, as delaying treatment could result in continued heavy bleeding and increased risk of complications for the client.
Choice D reason: Offering the medication now to prevent saturation of the perineal pad is also incorrect. The prescription specifies that the medication should be given in response to the saturation of the perineal pad within 15 minutes, not as a preventive measure. Administering oxytocin without the indicated condition could lead to unnecessary medication use and potential side effects.
A nurse is caring for a newborn who weighs 3,500 g. The nurse should record the newborn's weight as how many kg. (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
1000g=1kg 3500g=3500*1/1000
=3.5kg
A nurse is caring for a client who is postpartum and has a prescription for oxytocin 10 units IM one time only for the saturation of a perineal pad in 15 min or less. How should the nurse interpret this prescription?
Explanation
A. Offering the medication now to prevent saturation of the perineal pad is incorrect because the prescription specifies administering the medication only if the pad is saturated within 15 minutes. Preventative administration is not indicated.
B. Giving the medication each time the client saturates the perineal pad within 15 minutes is incorrect because the prescription states "one time only." Repeated administration is not in line with the prescription.
C. Administering the medication once if the client saturates the perineal pad within 15 minutes is correct. This interpretation aligns with the prescription's directive to give the medication one time only under the specified condition.
D. Waiting to administer the medication after the client saturates a perineal pad is incorrect because the prescription does not specify a waiting period after saturation. The medication should be given immediately if the saturation occurs within the 15-minute timeframe.
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.)
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.
