A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococcal infection.
Available is clindamycin 900 mg in 50 mL. How many mL/hr should the nurse set the IV pump to? (Round to the nearest whole number, use a leading zero if it applies, do not use a trailing zero)
Answer and Explanation

The Correct Answer is ["033"]

Step 1 is to calculate the number of milliliters (mL) that contain the ordered dose of 300 mg of clindamycin.

Step 2 is to divide the total milliliters (mL) from Step 1 by the infusion time in minutes to get the flow rate in mL/hour. Here are the calculations:

Step 1:

900 mg of clindamycin is in 50 mL.

To find the mL that contain 300 mg, set up a proportion:

(300 mg / 900 mg) = (x mL / 50 mL) Cross-multiply and solve for x:

x = (300 mg * 50 mL) / 900 mg x = 16.67 mL

Step 2:

The infusion time is 30 minutes.

Divide the total mL (16.67 mL) by the infusion time in hours to get the flow rate in mL/hour: Flow rate = 16.67 mL / (30 minutes / 60 minutes/hour)

Flow rate = 33.33 mL/hour

Round to the nearest whole number, using a leading zero if it applies, and no trailing zero: Flow rate = 033 mL/hour

Correct Answer is ["1370"]

Explanation

To calculate the total output for the client, we need to add up all the individual outputs:

  • The client voided 400 mL at 1100.
  • The client voided 350 mL at 1430.
  • The closed chest drainage system increased from 155 mL to 175 mL, which is an increase of 20 mL.
  • The NG tube has 575 mL in the drainage container.
  • The Jackson-Pratt drainage tube has 25 mL.

Adding all these amounts together, the total output that the nurse should record in the medical record is 1370 mL.

Here’s the calculation:

400 mL + 350 mL + (175 mL - 155 mL) + 575 mL + 25 mL = 1370 mL400mL+350mL+(175mL−155mL)+575mL+25mL=1370mL

So, the nurse should record a total output of 1370 mL in the medical record for the client.

Correct Answer is B

Explanation

Choice A rationale:
While taking colchicine with food can help minimize gastrointestinal side effects like nausea, it's not the most crucial instruction for this medication. The primary concern with colchicine is its potential for muscle toxicity.

Choice B rationale:
Colchicine can cause muscle pain, tenderness, or weakness, which can be a sign of a serious condition called rhabdomyolysis. Rhabdomyolysis involves the breakdown of muscle tissue, potentially leading to kidney damage and other complications.
It's crucial for patients to monitor for muscle pain and report it to their healthcare provider promptly if it occurs. Early detection and intervention can help prevent serious complications.

Choice C rationale:
Increased bruising is not a common side effect of colchicine. It's more frequently associated with medications that affect blood clotting, such as warfarin or aspirin.

Choice D rationale:
Grapefruit juice can interact with many medications, including colchicine. It can increase the concentration of colchicine in the bloodstream, potentially leading to toxicity.
It's crucial for patients taking colchicine to avoid grapefruit juice and other grapefruit products.
