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 inhaling deeply, which helps to expand the lungs and improve their capacity. This allows for more efficient oxygen exchange and can improve overall respiratory function. Increased mucus in the respiratory system (A) is not a benefit of deep-breathing exercises and can actually be a sign of respiratory issues. Decreased salivary production (B) is unrelated to deep-breathing exercises. Decreased oxygen levels (D) would be counterproductive to the goal of deep-breathing exercises, which aim to improve oxygen intake.

Correct Answer: C

Rationale: The correct answer is C: Burn fat. In cases of hyperglycemia from diabetes, the body may turn to burning fat for energy through a process called lipolysis. This is because the excess glucose in the bloodstream cannot be properly utilized by cells due to insulin insensitivity. Burning fat generates ketone bodies, which can be used as an alternative energy source. Burning sugar (A) is not efficient in hyperglycemic conditions. Burning proteins (B) is not preferred as it can lead to muscle breakdown. Burning minerals (D) is not a direct energy source for the body. Therefore, burning fat is the most suitable method for the body to find materials for energy in cases of 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) refers to turning around an axis, not bending backward. Supination (C) is the upward rotation of the forearm, not bending backward. Opposition (D) is the movement of the thumb towards the fingers, not bending backward. Therefore, the correct term for bending backward is dorsiflexion.

Correct Answer: B

Rationale: The correct answer is B (4 hours) because repositioning a resident on a mechanical ventilator is crucial to prevent pressure ulcers and maintain proper ventilation. Repositioning every 4 hours helps distribute pressure, improve circulation, and prevent skin breakdown. Choice A (5 hours) is too long, increasing the risk of complications. Choice C (3 hours) may be too frequent and could disrupt the patient's rest. Choice D (2 hours) is too frequent and may not allow enough time for the patient to rest and heal. Therefore, B is the most appropriate interval for repositioning a resident on a mechanical ventilator.

Correct Answer: B

Rationale: The correct answer is B: Obsessing over small things. Burnout often leads to heightened sensitivity and fixation on minor issues, causing individuals to obsess over small details. This behavior is a sign of emotional exhaustion and reduced effectiveness. Choices A, C, and D are incorrect as burnout typically manifests as increased irritability, decreased patience, and heightened frustration levels. These symptoms are contrary to the characteristics described in choices A, C, and D.
