(Pre Test ) Explanation: A telephone triage system, often managed by an automated attendant or a dedicated staff member, helps improve efficiency by appropriately routing calls to the correct department or person (e.g., billing, appointments, nurse line). This reduces wait times and ensures callers reach the right resource quickly.

Explanation: Nonmaleficence is the core ethical principle of “do no harm.” It obligates healthcare providers to avoid any action that could cause unnecessary harm to a patient.

Explanation: A thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall to remove excess fluid (pleural effusion) for diagnostic or therapeutic purposes.

Explanation: Submitting the same claim more than once for the same service is known as duplicate billing. Insurance payer systems are designed to detect this and will typically deny the duplicate claim to prevent paying for the same service twice.

Explanation: The universal sign of choking is when a person instinctively grabs their throat with one or both hands. This gesture signals an airway obstruction and the inability to breathe or speak.

(Pre Test ) Explanation: For proper accountability and financial tracking, a petty cash log must be maintained. Every time money is disbursed, a corresponding receipt or voucher for the expenditure must be collected and recorded in the log.

Explanation: For most types of shock, the recommended position is to have the patient lie flat on their back with their legs elevated about 8-12 inches. This helps to promote venous return to the heart and improve blood flow to vital organs.

Explanation: Catgut is an example of an absorbable suture material. It is made from the intestines of sheep or cattle and is gradually broken down and absorbed by the body’s enzymes over time, so it does not require removal.

Explanation: In healthcare settings, waste is segregated. Black bags are typically used for general, non-infectious, non-hazardous waste, similar to regular household trash. Infectious waste goes in red or biohazard bags.

Explanation: Comprehensive documentation is crucial for legal and medical accuracy. After suture removal, the record should include the number of sutures removed, the appearance of the wound (e.g., well-approximated, no signs of infection), and the patient’s response or tolerance of the procedure.

Explanation: The testes (singular: testis) are the primary male reproductive organs responsible for producing sperm (spermatogenesis) and synthesizing androgens, primarily testosterone.
