Using a flotation belt in a stationary position

Correct answer: At or near the water surface where movement generates surface waves

Wave drag occurs at the air-water interface where body movement creates surface waves; it is negligible during full submersion and maximal when the patient moves at the waterline.

Question 74: How does warm water immersion primarily affect skeletal muscle tissue?

Increases muscle fiber recruitment and strength output
Enhances anaerobic metabolic capacity
Reduces muscle tone and increases tissue extensibility (Correct answer)
Decreases peripheral blood flow to the extremities

Correct answer: Reduces muscle tone and increases tissue extensibility

Warm water immersion reduces muscle tone and increases soft tissue extensibility, facilitating stretching and range-of-motion activities.

Question 75: Which of the following is a sign of aquatic distress?

Panic and gasping (Correct answer)
Calm floating
Holding the wall
Strong swimming strokes

Correct answer: Panic and gasping

Panic and gasping are clear indicators of aquatic distress, signifying that an individual is struggling to breathe and stay afloat. Unlike calm floating or strong swimming, these signs suggest an immediate need for intervention to prevent drowning. Recognizing these cues is crucial for timely rescue and ensuring the safety of individuals in the water.
