A nurse is caring for a client who has an ankle sprain and a prescription for an aquathermia pad. Which of the following actions should the nurse take?
Apply the pad for 45 min per application.
Cover the pad with a pillowcase before application.
Set the temperature of the aquathermia pad to 50° C (122° F).
Use safety pins to hold the pad in place.
The Correct Answer is B
A. Apply the pad for 45 min per application: Heat therapy should generally be limited to 20 to 30 minutes to avoid burns and rebound vasoconstriction. Applying for 45 minutes increases the risk of tissue injury and is not recommended.
B. Cover the pad with a pillowcase before application: Placing a thin barrier, such as a pillowcase, between the aquathermia pad and the skin helps prevent direct contact and reduces the risk of burns. This is the safest and most appropriate action.
C. Set the temperature of the aquathermia pad to 50° C (122° F): The typical safe range for aquathermia pads is around 40° C (104° F). Setting the temperature to 50° C poses a high risk of skin injury, especially in clients with impaired sensation or circulation.
D. Use safety pins to hold the pad in place: Safety pins can puncture the tubing of the pad, leading to leaks and malfunction. Straps or covers designed for the device should be used instead to secure it safely.

Correct Answer is D
Explanation
A. A client who needs their daily weight taken with a bed scale: Daily weight is important for monitoring fluid status, but it is not immediately life-threatening if delayed. This task can be completed after more urgent client needs are addressed.
B. A client who has a leg ulcer and needs their dressing changed: Dressing changes are important for preventing infection and promoting healing, but this intervention is not urgent compared to risks involving airway or nutrition.
C. A client who has an indwelling urinary catheter bag that needs to be emptied: Emptying a catheter bag helps with comfort and infection control but does not represent a priority safety concern. It can safely wait until more urgent tasks are completed.
D. A client who has dysphagia and has a scheduled feeding: Dysphagia places the client at high risk for aspiration during feeding, which can compromise the airway and lead to respiratory complications. This client requires the nurse’s immediate attention to ensure safe feeding.
Correct Answer is A
Explanation
The pressure–volume loop shows a "beaking" pattern (upper inflection point, where the loop flattens and bends back). This indicates overdistention of the alveoli from excessive tidal volume or high inspiratory pressure. The flow–volume loop shows a scooped-out appearance during expiration, which is typical of airflow obstruction such as COPD or asthma. These loops are most consistent with obstructive lung disease with overdistention such as in COPD.
