What is the primary purpose of performing range-of-motion (ROM) exercises?

Correct Answer: B

Rationale: The primary purpose of performing range-of-motion (ROM) exercises is to prevent muscle atrophy and joint contractures. These exercises are crucial in maintaining joint mobility and muscle flexibility, especially in patients who are immobilized or have limited mobility. Improving cardiovascular fitness (Choice A) involves different types of exercises that target the heart and blood vessels, not specifically ROM exercises. Increasing respiratory function (Choice C) is typically achieved through breathing exercises and activities that enhance lung capacity. Enhancing cognitive function (Choice D) is usually addressed through cognitive exercises and activities that stimulate brain function.

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention in an acute asthma attack. Bronchodilators help to quickly open the airways, relieve bronchospasm, and improve breathing. Encouraging the patient to drink fluids may be beneficial for other conditions but is not the priority in an acute asthma attack. Applying a high-flow oxygen mask may be necessary in severe cases of respiratory distress but is not the initial priority when managing an acute asthma attack. Performing chest physiotherapy is not indicated as the primary intervention for an acute asthma attack and may not address the immediate need to open the airways and improve breathing.

Correct Answer: C

Rationale: Encouraging family presence is the most appropriate intervention for managing delirium in elderly patients. This intervention provides orientation, reassurance, and comfort, which can help reduce confusion and anxiety, thus aiding in managing delirium. Keeping the room brightly lit (Choice A) may worsen delirium as it can disrupt the patient's sleep-wake cycle. Administering sedatives (Choice B) should be avoided unless absolutely necessary due to the risk of worsening delirium. Restricting fluids (Choice D) is not a recommended intervention for managing delirium, as hydration is important for overall patient well-being.

Correct Answer: C

Rationale: The correct answer is C. Trimming toenails straight across and filing the edges is crucial in diabetic foot care to prevent ingrown toenails and foot injuries. Soaking feet daily can lead to dryness and skin breakdown, increasing the risk of infection. Selecting well-fitting shoes is important to prevent pressure points and skin damage, not tight-fitting shoes. Using heating pads can result in burns or injuries due to decreased sensation in diabetic feet, so it's essential to avoid them.

Correct Answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.
