Final answer:
The question involves medication reconciliation, which requires a careful review of patient medications. Additional tests such as CT scans, blood work, and urine analysis might be ordered based on a patient's health history and current symptoms. The case studies provided exemplify the importance of thorough investigation in the case of possible infections or diseases, as seen with potential appendicitis or C. difficile.
Step-by-step explanation:
The case presents a scenario where a medication reconciliation is being performed for a client. Medication reconciliation is a critical process in healthcare whereby a client's medication orders are reviewed to ensure consistency and accuracy throughout transitions in care. The question alludes to the need for further investigation of certain medications reported by the client, which is not uncommon if there is a discrepancy or if a medication poses potential risks, such as interactions with other drugs or conditions.
For example, reading through Marisa's health history, a doctor would be concerned about her recent hospitalization in Vietnam and the administration of antimicrobial drugs. These medicines, ceftazidime and metronidazole, could have potential interactions or side effects that necessitate additional tests such as a CT scan, blood work, or urine analysis. Notably, these tests would check for conditions like appendicitis or infections, both of which would significantly alter the course of treatment and might even necessitate urgent medical intervention.
In the case of Javier, who demonstrates the symptoms of abdominal cramping, watery diarrhea, fever, and the presence of blood in his stool after a cardiac procedure, a NAAT test (nucleic acid amplification test) could be crucial in diagnosing a possible C. difficile infection, which is a common and serious infection often associated with antibiotic use and healthcare settings.
