A nurse is reviewing the employee health program for new employees. Which of the following diagnostic assessments should the nurse recommend for all new employees to screen for the presence of tuberculosis?

A. Constipation: While constipation can be uncomfortable, it is not typically considered an immediate threat to a patient's health in a cardiac unit setting. It requires assessment and intervention but is not the highest priority.

B. Indigestion can be a subtle symptom of myocardial infarction (MI) or acute coronary syndrome (ACS), particularly in older adults, women, or clients with diabetes. Clients experiencing "indigestion" may be describing chest discomfort, which requires immediate assessment to rule out a cardiac event. Early identification and intervention for cardiac symptoms are critical to prevent further complications.

C. Swollen ankles can indicate fluid retention, which is a common sign of heart failure. While this symptom requires attention, it does not typically indicate an immediate life-threatening issue compared to potential cardiac ischemia associated with "indigestion."

D. Urinary frequency: This could be related to medications or other conditions. While it should be addressed, it is not the most critical issue compared to potential acute cardiac symptoms.

A. Varicella-zoster (chickenpox) requires airborne precautions due to its transmission via respiratory droplets or aerosols.

B. Vancomycin-resistant enterococcus (VRE) is typically transmitted through direct contact with contaminated surfaces or equipment and does not require droplet precautions.

C. Pertussis (whooping cough) is transmitted via respiratory droplets and requires droplet precautions to prevent transmission to others.

D. Rotavirus is primarily transmitted through the fecal-oral route and requires contact precautions, not droplet precautions.
