Exam 8: Advanced Intravenous Calculations

Change the dose ordered per min to dose per hr in the metric terms requested. Use a calculator for long division and multiplication. Verify your entries and answers by entering the data twice. -Drug per kg per min: $15 \text { mcg per kg per min }$ Weight: $100 \mathrm{~kg} .$ a. mcg per hr: b. mg per hr (to nearest tenth of an mg):

For an IV solution of Drug Y, 250 mg in 1000 mL, the hourly ordered drug is 10 mg. How many mL per hr will the rate be on the infusion pump?

Calculate the hourly intravenous (IV) flow rates. -The patient's IV is flowing at $10 \mathrm{~mL} \text { per hr. }$ Ordered: $2 \text { mg per hr }$ IV: $100 \mathrm{mg} \text { in } 500 \mathrm{~mL}$ of solution. a. What is the total drug:total mL ratio? b. How many mg per hr is the patient receiving? c. Is the patient receiving the correct amount of medication? d. What is the appropriate nursing action, if any?

Calculate the hourly intravenous (IV) flow rates. -Total drug: $500 \mathrm{mg} .$ Total volume: $250 \mathrm{~mL}$ . Hourly drug ordered: $10 \mathrm{mg} \text {. }$ What is the hourly volume (mL per hr to nearest tenth of an mL)?

Change the dose ordered per min to dose per hr in the metric terms requested. Use a calculator for long division and multiplication. Verify your entries and answers by entering the data twice. -Drug per kg per min: 6 mcg per kg per min Weight: 55 kg a. mcg per hr: b. mg per hr (to nearest tenth of an mg):

Ordered: Dobutamine (Dobutrex) at 1 mcg per kg per min to be infused. Patient weight is 70 kg. The Dobutrex has been placed in 1 L of D5W. What flow rate will you set (to nearest whole number)?

Change the dose ordered per min to dose per hr in the metric terms requested. Use a calculator for long division and multiplication. Verify your entries and answers by entering the data twice. -Drug per kg per min: 10 mcg per kg per min Weight: 75 kg a. mcg per hr: b. mg per hr (to nearest tenth of an mg):

Calculate the hourly intravenous (IV) flow rates. -Total drug: $400 \mathrm{mg} .$ Total volume: $250 \mathrm{~mL} \text {. }$ Hourly drug ordered: $5 \mathrm{mg} .$ What is the hourly volume (mL per hr to nearest tenth of an mL)?

Calculate the hourly intravenous (IV) flow rates. -Ordered: An IV of $2 \text { mcg per kg per min. }$ Available: The pharmacy-prepared IV contains $100 \mathrm{mg} \text { in } 250 \mathrm{~mL}$ Patient weight: $50 \mathrm{~kg} .$ a. What is the total drug:total mL ratio? b. How many mcg per hr are ordered? c. How many mg per hr are ordered? d. How many mL per hr are needed to the nearest tenth of an mL?

Calculate the hourly intravenous (IV) flow rates. -The patient's IV is ordered for $150 \text { mcg per min. }$ Available: $400 \mathrm{mg} \text { in } 250 \mathrm{~mL}$ a. What is the total drug:total mL ratio? b. How many mcg per hr should the patient receive? c. How many mg per hr should the patient receive? d. How many mL per hr should the patient receive to the nearest tenth of an mL?
