Question

A nurse is ventilating a client using a bag-valve mask with a capnography sensor and the client's PaCO2 level is 39 mmHg. How should the nurse interpret this finding?

Answer 1

Correct Answers:

The new nurse is appropriately ventilating the client.

Rationale :

💁‍♂️A PaCO₂ of 39 mmHg falls within the normal adult range of approximately 35–45 mmHg.

🌬️A normal PaCO₂ level indicates that the client is receiving adequate alveolar ventilation with the bag-valve mask.

⚖️Effective ventilation maintains appropriate removal of carbon dioxide without producing hypoventilation or hyperventilation.

💪Therefore, the finding supports that the nurse is providing appropriate ventilation rather than excessive or inadequate ventilation.

📌Core Message

A PaCO₂ of 39 mmHg indicates effective alveolar ventilation because carbon dioxide remains within the expected physiologic range during bag-valve-mask ventilation.

Answer 2

Correct Answers:

Full-thickness tissue loss with exposed subcutaneous tissue.

Rationale :

🩹A stage II pressure injury involves partial-thickness skin loss with exposed dermis and does not expose adipose tissue.

⬇️Progression to full-thickness skin loss with exposed subcutaneous tissue indicates worsening to a stage III pressure injury.

🔎A stage III injury extends through the dermis into subcutaneous tissue, representing greater tissue destruction than stage II.

⚠️Recognizing progression in pressure injury depth is essential for adjusting wound care and preventing further complications.

📌Core Message

A stage II pressure injury is worsening when it progresses to full-thickness tissue loss with exposed subcutaneous tissue, indicating development of a stage III pressure injury.

Answer 3

Correct Answers:

Remove the safety reminder device as soon as it is no longer needed.
Replace the device when it becomes soiled or wet.
Inspect the skin under the device frequently and with position changes.
Assess the circulation of the extremity distal to the safety reminder device.

Rationale :

🔓A safety reminder device should be discontinued as soon as it is no longer necessary because restraints should always be used for the shortest possible duration.

🧼A device that becomes wet or soiled should be replaced to protect skin integrity and maintain hygiene.

👀Frequent inspection beneath the device and during position changes helps identify pressure, irritation, or skin breakdown early.

🩸Assessing circulation distal to the device helps detect impaired blood flow, including changes in color, temperature, sensation, or pulse quality.

📌Core Message

Safe use of a safety reminder device requires frequent skin and circulation assessment, replacement when contaminated, and removal as soon as the restraint is no longer necessary.

Answer 4

Correct Answers:

Wash hands for at least 20 seconds.

Rationale :

🧼Effective handwashing requires scrubbing with soap and water for at least 20 seconds to reduce microorganisms.

🦠Proper hand hygiene decreases transmission of pathogens during home dressing changes and lowers the risk of wound infection.

🤲The client should clean all hand surfaces, including the palms, backs of hands, fingers, thumbs, and between fingers.

🚿Thorough rinsing and drying with a clean towel further support effective infection prevention.

📌Core Message

Washing the hands with soap and water for at least 20 seconds is an essential infection-control measure before performing wound dressing changes.

Answer 5

Correct Answers:

Decreased circulation

Rationale :

🩸A major physical hazard of a safety restraint device is impaired circulation when the device is too tight or improperly positioned.

🦵Reduced peripheral blood flow can cause numbness, pallor, coolness, swelling, weak pulses, and eventually tissue injury.

👀Frequent neurovascular assessment is necessary to identify circulatory compromise before permanent injury develops.

🚨Because impaired circulation can threaten tissue viability and limb function, it represents the greatest immediate physiological concern among the listed findings.

📌Core Message

The greatest immediate physical concern with a safety restraint device is decreased circulation because prolonged vascular compression can cause ischemia and tissue injury.

Answer 6

Correct Answers:

Position the client to permit the gravitational flow of fluid.

Rationale :

🛏️Before beginning wound irrigation, the nurse should position the client so irrigating solution can flow from the wound into the collection basin by gravity.

💧Proper positioning prevents fluid from pooling within the wound and helps remove debris and microorganisms effectively.

🧼Wound irrigation should generally proceed from the least contaminated area toward the more contaminated area while avoiding unnecessary trauma.

🩹Correct preparation and positioning promote effective wound cleansing while protecting surrounding skin and linens from contamination.

📌Core Message

Proper client positioning before wound irrigation allows gravitational drainage of solution and contaminants away from the wound while promoting effective cleansing.

Answer 7

Correct Answers:

The number in the manometer when the sound disappeared.

Rationale :

🎧The diastolic blood pressure is identified at the point when the Korotkoff sounds disappear during cuff deflation in most adults.

🩸The disappearance of sounds represents the pressure at which arterial blood flow becomes unobstructed throughout the cardiac cycle.

📉The nurse records the actual manometer reading at the disappearance of the Korotkoff sounds without adding an arbitrary value.

💁‍♂️The first Korotkoff sound represents systolic pressure, while disappearance represents diastolic pressure.

📌Core Message

Diastolic blood pressure is documented from the manometer reading at the disappearance of Korotkoff sounds during cuff deflation.

Answer 8

Correct Answers:

Pause the procedure.

Rationale :

🛑When contamination of the sterile field occurs during central venous catheter insertion, the nurse should immediately pause the procedure to prevent further contamination.

🦠A central venous catheter provides direct access to the bloodstream, making strict sterile technique essential for preventing catheter-related bloodstream infection.

🧤Contaminated equipment or supplies must be replaced before the procedure can safely resume under sterile conditions.

⚠️Stopping the procedure immediately addresses the current safety threat before documentation or obtaining replacement supplies occurs.

📌Core Message

A contaminated sterile field during central venous catheter insertion requires immediate interruption of the procedure so sterility can be reestablished before invasive care continues.

Answer 9

Correct Answers:

A client with a recent stroke and left-sided weakness.

Rationale :

🧠A recent stroke with unilateral weakness significantly increases the risk of falls and injury during transfers because of impaired motor control and balance.

⚖️Left-sided weakness can interfere with weight bearing, coordination, postural stability, and the client's ability to assist safely with movement.

🦽The nurse should evaluate the client's transfer ability and use appropriate assistance or mechanical equipment based on mobility status.

🛡️Recognizing neurological deficits before transfer helps prevent falls, caregiver injury, and further client harm.

📌Core Message

A client with a recent stroke and unilateral weakness has the greatest transfer-injury risk because impaired strength and balance reduce safe mobility and weight-bearing capacity.

Answer 10

Correct Answers:

Abduction

Rationale :

↔️Abduction is movement of a body part away from the midline of the body.

🦾Raising an arm laterally away from the trunk is a common example of shoulder abduction.

🧭The opposite movement, bringing a body part back toward the midline, is called adduction.

📚Understanding these directional terms allows accurate documentation of range-of-motion assessment and musculoskeletal function.

📌Core Message

Abduction describes movement of a body part away from the body's midline and is a fundamental term used during range-of-motion assessment.
