When given a scheduled morning medication, the client states, "I haven't seen that pill before. Are you sure it's correct?" The nurse checks the medication administration record and verifies that it is listed. Which is the nurse's best response?

A) Omeprazole and clarithromycin: Omeprazole is a proton pump inhibitor (PPI) that reduces stomach acid production, and clarithromycin is an antibiotic used to target Helicobacter pylori (H. pylori), the bacteria responsible for many peptic ulcers. In dual therapy for H. pylori eradication, omeprazole is used to create a less acidic environment, enhancing the effectiveness of antibiotics like clarithromycin. This combination is one of the most commonly used regimens in the treatment of peptic ulcer disease caused by H. pylori.

B) Ciprofloxacin and sucralfate: Ciprofloxacin is an antibiotic, and sucralfate is a medication used to coat the stomach lining to protect it from acid. While ciprofloxacin may be effective against certain bacterial infections, it is not typically used in dual therapy for H. pylori infections. Sucralfate is not an antibiotic and does not directly treat the bacterial cause of peptic ulcers, so this combination would not be ideal for H. pylori eradication.

C) Cimetidine and amoxicillin: Cimetidine is an H2-receptor antagonist used to reduce stomach acid production, and amoxicillin is an antibiotic that could potentially target H. pylori. However, this combination is less commonly used compared to PPI-based therapies. Cimetidine does not reduce acid as effectively as omeprazole (a PPI), making this combination less ideal for eradicating H. pylori.

D) Tetracycline and metronidazole: Both tetracycline and metronidazole are antibiotics used to treat infections, including H. pylori, but they are typically used in triple therapy regimens along with a PPI, not in dual therapy. While they can be effective in treating H. pylori, the combination of a PPI like omeprazole with clarithromycin remains the preferred choice for dual therapy.

A) Evaluation: Evaluation is the phase where the nurse assesses whether the goals or outcomes of the care plan have been met. It involves determining if the interventions provided were effective in achieving the desired outcomes. In this scenario, the nurse is still
gathering information before the action is taken, so evaluation is not the correct phase.

B) Planning: Planning is the phase in the nursing process where the nurse develops a care plan, which includes setting goals and determining interventions based on the client's needs. Although reviewing the medical record and blood glucose level is important for planning the administration of insulin, this is more about gathering data rather than forming a plan of care.

C) Implementation: Implementation refers to the actual delivery of the nursing interventions or actions. In this case, administering the insulin would be part of the implementation phase, but reviewing the medical history and obtaining a fingerstick blood glucose reading are steps taken before implementing the medication.

D) Assessment: The nurse is collecting pertinent information about the client’s condition, including reviewing the medical record and obtaining the blood glucose level. Assessment is the first step in the nursing process and involves gathering information to help guide clinical decisions.

E) Diagnosis: Diagnosis is the phase in which the nurse analyzes the assessment data to identify the client’s health problems or potential risks. While the nurse is collecting data, the diagnosis comes after the assessment phase, when the nurse has enough information to make a clinical judgment about the client's health status.
