A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?

Stop the oral contraceptive immediately.

Take the medications at least 12 hours apart.

Use an additional form of contraception.

Avoid prolonged exposure to direct sunlight.

Answer and Explanation

The Correct Answer is C

Choice A reason: Stopping the oral contraceptive immediately is not necessary and may increase the risk of unintended pregnancy. Erythromycin can reduce the effectiveness of oral contraceptives by interfering with their metabolism, but it does not make them completely ineffective.

Choice B reason: Taking the medications at least 12 hours apart is not sufficient to prevent the interaction between erythromycin and oral contraceptives. The interaction can occur regardless of the timing of the doses.

Choice C reason: Using an additional form of contraception is the best instruction for the client who is taking an oral contraceptive and erythromycin. This can prevent pregnancy in case the oral contraceptive fails due to the interaction with erythromycin. The additional form of contraception should be non-hormonal, such as a barrier method or a copper intrauterine device.

Choice D reason: Avoiding prolonged exposure to direct sunlight is a good advice for anyone taking erythromycin, as it can cause photosensitivity and increase the risk of sunburn. However, this is not related to the interaction with oral contraceptives and does not affect their efficacy.

Correct Answer is C

Explanation

Choice A reason: Encouraging an increase in oral intake is not necessary in this situation, as dark urine is not a sign of dehydration or fluid imbalance. Dark urine may be caused by certain foods, medications, or medical conditions, but it does not indicate a need for more fluids.

Choice B reason: Measuring the client's urinary output is not relevant to this situation, as dark urine is not a sign of urinary retention or obstruction. Urinary output may vary depending on fluid intake, activity level, or other factors, but it does not reflect urine color.

Choice C reason: Explaining that color change is normal is the appropriate action to take, as dark urine is a common and harmless side effect of carbidopa/levodopa, which is a combination drug used to treat Parkinson's disease by increasing dopamine levels in the brain. Carbidopa/levodopa can cause urine to turn brown, black, or red, but this does not affect the function or health of the kidneys or bladder.

Choice D reason: Obtaining a specimen for a urine culture is not necessary in this situation, as dark urine is not a sign of infection or inflammation. A urine culture may be indicated if the client has symptoms such as fever, pain, burning, frequency, or urgency, but it does not diagnose urine color

Correct Answer is ["42"]

Explanation

The correct answer is 42gtt/min.

To calculate the infusion rate, use the formula:

gtt/min = (volume in mL x drop factor in gtt/mL) / time in min

Plug in the given values:

gtt/min = (500 mL x 10 gtt/mL) / 120 min

gtt/min = 5000 gtt / 120 min

gtt/min = 41.67 gtt/min

Round to the nearest whole number:

gtt/min = 42 gtt/min
