A nurse is caring for a client who reports experiencing alteration in sense of smell following surgery for a total laryngectomy. The nurse should address the client's concern through which of the following response?

A. Poorly coordinated care and nosocomial infections are examples of errors: While poorly coordinated care can lead to adverse events, nosocomial infections are typically classified as healthcare-associated infections rather than errors. Errors generally refer to mistakes made in clinical practice that can lead to harm, whereas nosocomial infections are outcomes that arise from the healthcare environment.
B. As many as 90% of medication errors are preventable: This statement is true and highlights the significant opportunity for improvement in patient safety. Recognizing that a large percentage of medication errors can be prevented underscores the importance of implementing safety protocols, effective communication, and education to reduce the likelihood of errors occurring in clinical practice.
C. Errors of execution are usually intentional and occur because of time or resource constraints: This statement is misleading, as errors of execution typically refer to mistakes made during the performance of a task rather than intentional actions. These errors often occur due to lack of knowledge, skill, or attention rather than being intentional, and they are not solely attributed to time or resource constraints.
D. Medication errors are adverse events: While medication errors can lead to adverse events, not all medication errors result in harm. An adverse event is defined as an injury caused by medical management rather than the underlying condition of the patient, so this statement is not entirely accurate. Medication errors can be classified as near misses or adverse events, depending on whether they resulted in harm to the patient.

A. The importance of adhering closely to the prescribed medication regimen. Tuberculosis requires strict adherence to a long-term antibiotic regimen, typically lasting 6 to 9 months, to prevent drug resistance, treatment failure, and disease relapse. Noncompliance can lead to multidrug-resistant TB (MDR-TB), which is more difficult to treat. Directly observed therapy (DOT) is often recommended to ensure adherence.
B. The client must remain in respiratory isolation until medication treatment ends. While respiratory isolation is essential for active TB, it is not required until the full course of treatment is completed. Isolation is typically maintained until the client has received at least two weeks of effective therapy, symptoms improve, and three consecutive sputum smears are negative for acid-fast bacilli (AFB).
C. The fact that the disease is self-limiting, but can take up to two years to resolve. TB is not self-limiting; without proper treatment, it can persist indefinitely, worsen, and become fatal. Standard treatment with first-line drugs such as isoniazid, rifampin, ethambutol, and pyrazinamide effectively eradicates the infection within 6 to 9 months in most cases.
D. The importance of participating in physical therapy to re-establish functional abilities. While TB can cause fatigue and weakness, physical therapy is not a primary focus of treatment. The priority is to eradicate the infection through strict medication adherence, as untreated TB can progress to severe pulmonary damage, systemic involvement, and complications.
