A nurse is teaching a client who has a new diagnosis of rheumatoid arthritis. Which of the following statements should the nurse include in the teaching?

B. Respiratory infections can spread via droplets, necessitating airborne precautions and isolation in a private negative pressure room to prevent transmission to other clients and healthcare workers.

A A compound fracture involves an open wound where the bone has punctured the skin. While this client may require isolation precautions due to the open wound, the primary concern is not infectious in nature.

C. Aspiration pneumonia can be caused by inhalation of oral or gastric contents into the lungs, leading to infection. Therefore, such a client does not require isolation.

D Acute ketoacidosis in diabetes mellitus is a metabolic emergency but is not typically contagious or requiring isolation precautions for infection control.

A. The client presents with symptoms and signs suggestive of acute coronary syndrome, including chest pain, tachycardia, and ECG changes (ST segment elevation and T wave changes). Elevated troponin levels indicate myocardial injury. Cardiac catheterization is typically indicated in acute coronary syndrome to assess coronary artery anatomy and potentially perform interventions like angioplasty or stenting to restore blood flow to the heart muscle.
B. Continuous heparin infusion is commonly used in the management of acute coronary syndrome to prevent further clot formation and stabilize the condition. It helps in reducing the risk of thrombus formation in the coronary arteries, which is crucial in cases of myocardial infarction.
C. Ambulation is generally not recommended during the acute phase of myocardial infarction or unstable angina. The client's symptoms, such as chest pain, shortness of breath, and diaphoresis, indicate ongoing cardiac compromise. Ambulation could potentially worsen the client's condition or lead to adverse events.
D. Metoprolol is a beta-blocker used to reduce heart rate, blood pressure, and myocardial oxygen demand. While it is indicated in acute coronary syndrome to stabilize heart rate and reduce myocardial ischemia, increasing the dosage should be done cautiously and based on the client's response to initial therapy.
E. NPO status is typically indicated for clients undergoing procedures that require sedation or anesthesia, such as cardiac catheterization. It ensures the client's stomach is empty to reduce the risk of aspiration during the procedure. Given the potential need for cardiac catheterization in this client, obtaining a prescription for NPO status would be appropriate to prepare for the procedure and ensure safety.
F. Antibiotics are not routinely indicated in the management of acute coronary syndrome unless there is evidence of concomitant infection or specific clinical indications (e.g., pneumonia). In the absence of signs or symptoms of infection, requesting an antibiotic prescription is not warranted based on the client's current presentation.
