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: Nausea and diarrhea are possible side effects of ginkgo biloba, but they are not as serious or common as the risk of bleeding caused by the interaction with aspirin and non-steroidal anti-inflammatory drugs. Therefore, this information is not as important as choice c.

Choice B reason: Anxiety and headaches are not associated with the use of ginkgo biloba, but rather with the underlying condition of multiple sclerosis. Therefore, this information is not relevant or accurate for this client.

Choice C reason: Aspirin and non-steroidal anti-inflammatory drugs interact with ginkgo biloba, as both substances have antiplatelet effects that can increase the risk of bleeding. Therefore, this information is most important for the nurse to include in the teaching plan for this client, as the client should avoid taking these drugs while using ginkgo biloba or inform the healthcare provider if they are prescribed.

Choice D reason: Ginkgo biloba use should be limited and not taken during pregnancy, as there is insufficient evidence about its safety and efficacy for pregnant women. However, this information is not as important as choice c, as the client may not be pregnant or planning to become pregnant.

A. Implement neutropenic precautions. B. Inform the client that the medication has been effective. C. Review the client's culture and sensitivity reports. D. Assess the client's vital signs.

Correct Answer is B

Explanation

Choice A reason: Neutropenic precautions are necessary when the WBC count is critically low, typically below the normal range. Since the client’s WBC count is now within the normal range, these precautions are no longer required.

Choice B reason: Filgrastim is designed to increase white blood cell (WBC) production in individuals with neutropenia. In this case, the client’s WBC count has increased from 2,500/mm³ (2.5 x 10⁹/L) to 5,000/mm³ (5 x 10⁹/L), reaching the lower limit of the normal reference range (5,000 to 10,000/mm³ or 5 to 10 x 10⁹/L). This indicates that the medication has achieved its desired effect, and it is appropriate to inform the client of this positive outcome.

Choice C reason:reason: Reviewing culture and sensitivity reports would be relevant if there was evidence of infection or a need to evaluate ongoing treatment for an infection. This is not indicated by the scenario provided.

Choice D reason: While assessing vital signs is generally important, there is no indication in this scenario that an acute issue requiring immediate vital sign monitoring is present.
