A nurse is caring for client who is taking lisinopril (ACE inhibitor). Which of the following outcomes indicates a therapeutic effect of the medication?

A) Researcher:
The nurse is gathering evidence-based practice (EBP) on catheter-associated urinary tract infections (CAUTI), which involves systematically collecting, analyzing, and reviewing existing studies or guidelines to inform clinical practice. This is the role of the researcher in EBP. Nurses in this role contribute to improving patient outcomes by identifying best practices, assessing existing evidence, and implementing findings to reduce complications, such as CAUTIs.

B) Nurse manager:
While a nurse manager may oversee quality improvement projects, staffing, and other operational aspects of nursing care, they are not typically the ones actively gathering evidence-based data themselves. Nurse managers may utilize the findings from research but are not directly involved in the research process unless leading specific studies.
C) Case manager:
A case manager primarily coordinates care for individual patients, ensuring they receive the appropriate resources and follow-up care. They help manage the continuity of care across different settings but do not focus on gathering or researching evidence for clinical practices. Their role is more focused on patient outcomes and care delivery rather than generating evidence.

D) Educator:
While an educator might be involved in teaching staff or patients about preventing CAUTI, the role described in the question specifically refers to gathering evidence-based practice information. Educators may use research findings in their teaching, but gathering evidence is a distinct activity that fits the role of the researcher in EBP.

A) Orange juice:
Orange juice is generally safe to consume with most medications and does not pose significant risks like grapefruit juice. It is a good source of vitamin C and typically does not interact with prescription medications in a harmful way. However, some medications, particularly those for high blood pressure or heart conditions, may have specific instructions regarding food interactions.

B) Grapefruit juice:
Grapefruit juice should be avoided by clients taking certain medications, as it can interfere with the metabolism of various drugs. Grapefruit contains compounds that inhibit the action of the enzyme cytochrome P450 3A4, which plays a crucial role in metabolizing many medications. This can lead to higher levels of the drug in the bloodstream, increasing the risk of adverse effects or toxicity. Medications commonly affected include certain statins, calcium channel blockers, and immunosuppressants, among others.

C) Milk:
Milk is generally safe to consume with most medications, though it can interfere with the absorption of certain drugs, such as tetracycline antibiotics or some bisphosphonates (used for osteoporosis). However, milk is not as commonly problematic as grapefruit juice and is not a major concern for most prescription medications.

D) Carbonated beverage:
Carbonated beverages, such as soda, do not typically interact with most medications in a way that would cause harm. However, some carbonated drinks can cause gastrointestinal discomfort, especially when taken with certain medications that affect the stomach or intestines.
