The nurse is teaching a client about isometric exercise. Which activity indicates that the client understands the teaching? The client:
exerts pressure against a stationary object
lifts the body using a trapeze.
walks briskly around the hospital unit.
performs active range of motion to all joints.
The Correct Answer is A
A. Isometric exercises typically involve pushing or pulling against a stationary object or surface. This action creates muscle tension without joint movement.
B. Using a trapeze involves lifting the body and is more related to mobility assistance rather than isometric exercise. It typically involves movement and is not considered an isometric exercise.
C. Brisk walking is a cardiovascular exercise that involves movement and does not focus on muscle contraction without movement. It improves cardiovascular fitness and endurance rather than strength through isometric contraction.
D. Active range of motion exercises involve moving joints through their full range of motion using muscle strength. This is different from isometric exercises, which involve static muscle contractions without joint movement.

Correct Answer is D
Explanation
D. Unstageable pressure injuries are covered by slough (yellow, tan, gray, green, or brown) and/or eschar (tan, brown, or black) in the wound bed, making it difficult to determine the depth of tissue damage. If the wound over the sacrum is covered with dark, hard tissue that makes it impossible to visualize the depth of the wound, it could be considered unstageable
A. The description of tissue over the sacrum being dark, hard, and adherent to the wound edge suggests extensive tissue damage and possibly involvement of deeper structures like muscle or bone.
B. Stage II pressure injuries involve partial-thickness loss of skin with exposed dermis. These wounds are shallow and typically present as abrasions, blisters, or shallow ulcers.
C. Stage III pressure injuries involve full-thickness skin loss with visible adipose (fat) tissue in the ulcer. These wounds may also have undermining or tunneling.
Correct Answer is C
Explanation
C. If the stressor persists for a prolonged period and the body is unable to adapt or cope effectively, it enters the exhaustion phase. During this phase, the body's resources become depleted. The client experiences decreased energy, reduced ability to cope with stress, and may develop stress-related illnesses or complications.
A. It is characterized by the body's immediate response to a stressor, where physiological changes occur such as increased heart rate, heightened senses, and activation of the fight-or-flight response.
B. After the initial alarm reaction, if the stressor persists, the body enters the resistance phase. In this phase, physiological changes stabilize as the body attempts to cope with the stressor.
D. This phase occurs if the stressor is removed or successfully managed, allowing the body to recover and return to a state of homeostasis. During recovery, the body repairs any damage caused by the stress response and replenishes its energy and resources.
