A patient is currently on an oral contraceptive and has been prescribed erythromycin. What advice should the nurse provide to the patient?

Utilize an additional form of contraception.

Immediately discontinue the oral contraceptive.

Ensure a 12-hour gap between taking the medications.

Avoid prolonged exposure to direct sunlight.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Erythromycin is an antibiotic that can potentially reduce the effectiveness of oral contraceptives. Therefore, patients who are taking both erythromycin and an oral contraceptive should be advised to use an additional form of contraception to prevent unintended pregnancy.

Choice B rationale

Immediately discontinuing the oral contraceptive is not necessary when taking erythromycin. Instead, the patient should be advised to use an additional form of contraception.

Choice C rationale

Ensuring a 12-hour gap between taking the medications is not a recommended strategy for managing the potential interaction between erythromycin and oral contraceptives. The patient should be advised to use an additional form of contraception.

Choice D rationale

Avoiding prolonged exposure to direct sunlight is a general recommendation for sun protection, but it is not specifically related to the use of erythromycin or oral contraceptives.

Correct Answer is ["42"]

Explanation

To calculate the infusion rate in gtt/min, we first need to calculate the infusion rate in mL/hr. The formula for this is:

Step 1: Calculate the infusion rate in mL/hr

Infusion rate (mL/hr)=Total time (hr)Total volume (mL) Substituting the given values: Infusion rate (mL/hr)=2 hr mL=250 mL/hr

Step 2: Convert the infusion rate from mL/hr to gtt/min Infusion rate (gtt/min)=60 min/hrInfusion rate (mL/hr)×Drop factor (gtt/mL).

Substituting the given values: Infusion rate (gtt/min)=60 min/hr mL/hr×10 gtt/mL ≈42 gtt/min Therefore, the nurse should regulate the infusion to approximately 42 gtt/min.

Correct Answer is ["200"]

Explanation

The correct answer is 200 mL/h.

Step 1: The client has been prescribed ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour.

Step 2: The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL12. Step 3: To calculate the infusion rate, the nurse should use the formula: Infusion rate (mL/hr)

= Volume (mL) / Time (hr)3.

Step 4: In this case, the volume is 200 mL and the time is 1 hour. Step 5: Therefore, Infusion rate (mL/hr) = 200 mL ÷ 1 hr.

Step 6: Infusion rate (mL/hr) = 200 mL/hr.
