The nurse is caring for a client receiving a prescription for sucralfate to treat a peptic ulcer. Which instruction should the nurse provide during discharge education?

A. Stop the oral contraceptive immediately: There is no need to stop the oral contraceptive when starting erythromycin. Erythromycin is an antibiotic that may reduce the effectiveness of oral contraceptives, but it does not necessitate discontinuing the contraceptive method.
B. Take the medications at least 12 hours apart: There is no specific requirement to space out the administration of erythromycin and oral contraceptives by 12 hours. The primary concern with these medications is the potential interaction affecting contraceptive efficacy, not the timing of their administration.
C. Use an additional form of contraception: This is the most appropriate instruction. Erythromycin can potentially reduce the effectiveness of oral contraceptives by affecting their metabolism. To prevent unintended pregnancy, it is recommended to use an additional form of contraception (such as condoms) while taking erythromycin.
D. Avoid prolonged exposure to direct sunlight: Erythromycin does not typically cause significant photosensitivity issues that would require avoiding sunlight. The more pertinent concern with erythromycin and oral contraceptives is the potential interaction affecting the effectiveness of the contraceptive method.

A. Determine presence of abdominal pain: Chronic use of ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can lead to gastrointestinal issues such as ulcers or bleeding. Abdominal pain is a critical symptom that can indicate these serious side effects. Therefore, assessing for abdominal pain is the most important action to identify potential adverse effects related to prolonged NSAID use.
B. Palpate volume of pedal pulses: While assessing pedal pulses is important for evaluating circulation and potential peripheral vascular issues, it is not the primary concern related to the long-term use of ibuprofen. This assessment does not directly address the potential gastrointestinal complications of NSAID use.
C. Assess back pain using numeric scale: Although it is important to monitor the effectiveness of ibuprofen in managing back pain, this assessment does not address the potential side effects of prolonged use. Evaluating pain levels is useful for treatment efficacy but is secondary to monitoring for adverse effects.
D. Evaluate ongoing sleep patterns: While sleep patterns can be affected by pain or medication, they are not the most immediate concern regarding the side effects of long-term ibuprofen use. The potential gastrointestinal issues related to NSAID use take precedence.
