The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?

Diminished renal output.

Pruritis and macular rash.

Vomiting and diarrhea.

Vaginal discharge.

Answer and Explanation

The Correct Answer is B

A) Diminished renal output:
Diminished renal output could be a potential concern with cefoxitin administration, as it is primarily excreted by the kidneys. However, it is not specifically related to the client’s allergy to penicillin. While it warrants monitoring, it is not the most critical finding to report in this context.

B) Pruritis and macular rash:
The development of pruritis (itchiness) and a macular rash (flat, discolored skin lesions) following the administration of cefoxitin in a client with a documented allergy to penicillin is a significant finding. It suggests a possible allergic reaction to cefoxitin, which belongs to the cephalosporin class of antibiotics. Cross-reactivity between penicillin and cephalosporins is well-documented, with some cephalosporins having a higher risk of allergic reactions in individuals with penicillin allergy. Therefore, pruritis and rash in this context may indicate an allergic response, and it is crucial to report this finding promptly to the healthcare provider for further evaluation and management.

C) Vomiting and diarrhea:
While gastrointestinal symptoms such as vomiting and diarrhea can occur as adverse effects of cefoxitin, they are not specific to an allergic reaction and may occur with various medications. While it is essential to monitor for these symptoms, they are not the most important findings to report in the context of a known penicillin allergy.

D) Vaginal discharge:
Vaginal discharge is not typically associated with an allergic reaction to cefoxitin. While changes in vaginal discharge may be clinically relevant in certain contexts, such as indicating a possible yeast infection or bacterial vaginosis, it is not directly related to the client’s allergy to penicillin or the administration of cefoxitin.

Correct Answer is B

Explanation

A) Stop the oral contraceptive immediately:
This instruction is incorrect and potentially harmful. Suddenly stopping oral contraceptives can lead to unintended pregnancy and disrupt the client's menstrual cycle. It's crucial for the client to continue taking their oral contraceptive unless advised otherwise by their healthcare provider.

B) Use an additional form of contraception:
This is the correct recommendation. Erythromycin is an antibiotic that can reduce the effectiveness of oral contraceptives by altering gut flora and potentially interfering with their absorption. Therefore, using an additional form of contraception, such as condoms, is advised while taking erythromycin to prevent unintended pregnancy.

C) Take the medications at least 12 hours apart:
While spacing medications apart can sometimes minimize interactions, specific instructions regarding the timing of erythromycin and oral contraceptive administration should be obtained from the healthcare provider. Simply spacing the medications apart may not sufficiently prevent contraceptive failure.

D) Avoid prolonged exposure to direct sunlight:
This instruction is unrelated to the interaction between erythromycin and oral contraceptives. While erythromycin can increase sensitivity to sunlight (photosensitivity), it does not directly affect the effectiveness of oral contraceptives. Therefore, while it's important to advise clients to protect themselves from sun exposure while taking erythromycin, it's not directly related to contraceptive use.

A. Allow the client to take the medication up to 1 hour after breakfast. B. Instruct the client to take it when the meal tray is delivered. C. Document the client's refusal of the medication at this time. D. Explain the need to take the medication at least 1 hour before meals.

Correct Answer is D

Explanation

A) Allow the client to take the medication up to 1 hour after breakfast:
Administering sucralfate up to 1 hour after breakfast may not provide optimal effectiveness as it should ideally be taken on an empty stomach to form a protective barrier over irritated areas in the stomach and intestines before food intake. Taking it after breakfast might not allow sufficient time for the medication to coat these areas adequately.

B) Instruct the client to take it when the meal tray is delivered:
Taking sucralfate with meals or when the meal tray is delivered is not recommended as food can interfere with its effectiveness. It is best taken on an empty stomach to allow it to coat the stomach lining without interference from food, ensuring maximum therapeutic benefit.

C) Document the client's refusal of the medication at this time:
Documenting a refusal should only be done if the client declines after receiving appropriate education and understanding. Simply refusing the client's request without providing education on the proper timing for taking sucralfate would not be appropriate.

D) Explain the need to take the medication at least 1 hour before meals:
This is the correct response. Educating the client about the importance of taking sucralfate at least 1 hour before meals ensures optimal effectiveness. This timing allows the medication to form a protective barrier over irritated areas in the stomach and intestines before food intake, maximizing its therapeutic benefit.
