A benefit from the regular use of deep-breathing exercises is

Correct Answer: C

Rationale: The correct answer is C: Increased lung capacity. Deep-breathing exercises involve taking slow, deep breaths, which can strengthen the respiratory muscles and improve the efficiency of oxygen exchange in the lungs. This leads to an increase in lung capacity over time. Choice A is incorrect as deep-breathing exercises actually help in clearing mucus from the respiratory system. Choice B is incorrect as deep-breathing exercises do not decrease salivary production. Choice D is incorrect as deep-breathing exercises actually help in increasing oxygen levels in the body by improving oxygen intake and utilization.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Hyperglycemia means high blood sugar levels. 2. In hyperglycemia, the body turns to burning fat for energy. 3. This process is called lipolysis, where fats are broken down into fatty acids for energy production. 4. Burning fat helps lower blood sugar levels. 5. Burning sugar (choice A) can worsen hyperglycemia. 6. Burning proteins (choice B) is inefficient and can lead to muscle breakdown. 7. Burning minerals (choice D) does not provide energy. Summary: - Choice C is correct as burning fat is the body's method to find energy during hyperglycemia. - Choices A, B, and D are incorrect as they do not effectively address the energy needs during hyperglycemia.

Correct Answer: B

Rationale: The correct answer is B: Dorsiflexion. Bending backward is the movement of bringing the top of the foot towards the shin, which is dorsiflexion at the ankle joint. Rotation (A) is the movement around an axis, not bending backward. Supination (C) is the movement of turning the palm or foot upward, not bending backward. Opposition (D) is the movement of bringing the thumb and little finger together, not bending backward. Therefore, the correct term for bending backward is dorsiflexion.

Correct Answer: B

Rationale: The correct answer is B: 4 hours. Repositioning a ventilated resident every 4 hours helps prevent pressure injuries, improves ventilation efficiency, and ensures optimal lung expansion. Repositioning too frequently can disrupt care and lead to infection risks. Choices A, C, and D are incorrect because repositioning every 5, 3, or 2 hours respectively may be too infrequent or excessive, compromising resident care and comfort.

Correct Answer: B

Rationale: The correct answer is B: Obsessing over small things. Burnout often leads to increased irritability and fixation on minor issues. This behavior reflects a lack of emotional resilience and can indicate a person is overwhelmed and exhausted. Choices A, C, and D are incorrect because being slow to anger, having lots of patience, and lack of frustration are not typical signs of burnout. In fact, burnout can lead to increased frustration, impatience, and a shorter fuse due to emotional exhaustion and depletion of energy reserves.
