The nurse calculates that 8 ml of cefazolin is to be drawn from a vial after reconstitution. The instructions state that the medication is to be further diluted in 50 mls of NSS for IV administration and to run over 30 minutes. At what rate will the nurse set to infusion pump to deliver the medication?
The Correct Answer is ["116"]
To calculate the infusion rate, we'll follow these steps:
Determine the total volume to be administered:
8 mL (drawn from the vial) + 50 mL (dilution with NSS) = 58 mL
Calculate the infusion rate:
58 mL ÷ 30 minutes = 1.93 mL/minute
Convert mL/minute to mL/hour:
1.93 mL/minute × 60 minutes/hour = 116 mL/hour

Correct Answer is B
Explanation
A) "You can take 81 mg of enteric coated aspirin with orange juice at lunch time": While enteric-coated aspirin can help reduce gastrointestinal irritation, taking it with orange juice is not advisable. Citrus can increase gastric acidity, which might irritate the GI tract further, especially in a patient with a history of GI bleeding.
B) "Take the aspirin with a glass of milk or food in the morning": This instruction is appropriate as taking aspirin with food or milk can help minimize gastrointestinal irritation and promote safer use, especially in a client with iron deficiency anemia from a GI bleed. It also helps with absorption and can reduce the risk of an upset stomach.
C) "Take a baby aspirin with a full glass of cold water at bedtime": Taking aspirin with only water, particularly at bedtime, may increase the risk of gastric irritation and does not provide the protective effect that food or milk would. This is not the best practice for someone with a history of GI issues.
D) "It's ok to take the aspirin with some ginseng tea in the evening": Ginseng can interact with blood-thinning medications and may increase bleeding risk. Advising the client to combine aspirin with ginseng tea could be harmful, especially given their history of GI bleeding. This is not a safe or appropriate recommendation.
Correct Answer is C
Explanation
A. Monitor serum sodium levels: While serum sodium levels can provide some information about fluid balance, they are not the most direct indicator of the effectiveness of furosemide
in reducing peripheral edema.
B. Auscultate breath sounds: This is important for monitoring potential fluid overload or pulmonary complications, but it does not directly assess the reduction of peripheral edema, which is the primary concern with furosemide administration.
C. Perform daily weights: This method is the best way to evaluate the client's response to furosemide. Daily weights can provide a clear indication of fluid status and changes in peripheral edema, as a decrease in weight typically reflects effective diuresis.
D. Take the blood pressure: While monitoring blood pressure is important, especially in clients receiving diuretics, it does not specifically measure the effectiveness of the medication in addressing peripheral edema.
