Choice A rationale

Handling sterile items with clean hands is a violation of surgical asepsis principles. Even if hands are washed, they are not sterile and will immediately contaminate any sterile item they touch. Sterile objects must only come into contact with other sterile objects to maintain the integrity of the sterile field. Using clean hands would introduce microorganisms to the supplies, increasing the patient's risk for a healthcare-associated infection during the dressing change or surgical procedure.

Choice B rationale

While it is true that the outer one-inch border of a sterile field is considered contaminated, this principle explains the boundaries of the field rather than the method for adding new supplies. Understanding the border helps the nurse know where it is safe to place items, but it does not provide a mechanism for introducing new sterile items into the center of the field during a procedure. Correct placement requires dropping items or using a sterile tool to move them.

Choice C rationale

Standard latex or nitrile gloves are clean but not sterile. Grabbing new sterile supplies with clean gloves will contaminate the supplies and subsequently the entire sterile field if those supplies are placed upon it. To handle sterile items directly, the nurse must perform a surgical hand scrub and don sterile gloves. Using regular gloves is appropriate for many tasks, but it is insufficient for maintaining the strict environment required for a sterile dressing change.

Choice D rationale

Using sterile forceps is a correct and recognized method for adding or rearranging items on a sterile field. The forceps, being sterile themselves, can safely touch other sterile items without introducing contaminants. This allows the nurse to maintain the aseptic chain while adjusting the layout of the field or adding small components like gauze or instruments. It is a precise way to manage the sterile area without needing to change gloves or risk accidental contact.

Choice A rationale

Bronchial lung sounds are normal, high-pitched, loud sounds heard over the trachea and larynx. They are characterized by a short inspiratory phase and a long expiratory phase. While hearing these sounds in the peripheral lung fields might indicate an abnormality like consolidation, the term itself refers to a specific type of breath sound rather than the structural pathology of lung collapse or the incomplete expansion of the alveolar units within the pulmonary system.

Choice B rationale

Surfactant is a lipoprotein complex produced by Type II alveolar cells that reduces surface tension at the air-liquid interface within the alveoli. Its primary function is to prevent the lungs from collapsing during expiration by making it easier for the alveoli to expand during inhalation. While a deficiency in surfactant can lead to lung collapse, the surfactant itself is a substance, not the clinical condition of collapsed or unexpanded lung tissue described in the question.

Choice C rationale

Bradypnea is a clinical sign defined as an abnormally slow respiratory rate, typically fewer than 12 breaths per minute in an adult. This condition can be caused by various factors, including drug overdose, metabolic derangements, or increased intracranial pressure. While a slow respiratory rate can lead to poor lung expansion over time, it is a measurement of breathing frequency and does not describe the anatomical state of the lung tissue or alveolar collapse.

Choice D rationale

Atelectasis is the medical term for the partial or complete collapse of a lung or a lobe of a lung, occurring when the alveoli become deflated or filled with alveolar fluid. It is common after surgery or in patients who are bedridden and cannot breathe deeply. This condition reduces the surface area available for gas exchange, potentially leading to hypoxemia. Management often includes deep breathing exercises, coughing, and the use of incentive spirometry to re-expand the lung tissue.
