Correct Answer: A

Rationale: The correct answer is A: Poor hygiene and dehydration are common risk factors for urinary tract infections (UTIs). While choices B, C, and D may play a role in certain cases, poor hygiene and dehydration are more universally recognized as key factors contributing to UTIs. Increased sexual activity and pregnancy (choice B) can also increase the risk of UTIs, but they are not as universal as poor hygiene and dehydration. Choices C and D, the use of urinary catheters and prolonged bed rest, and family history and obesity, respectively, are risk factors for UTIs but are not as commonly associated as poor hygiene and dehydration.

Correct Answer: B

Rationale: The correct answer is to check for air leaks in the tubing. Air leaks can compromise the function of the chest tube, leading to inadequate drainage and potentially causing complications for the client. Clamping the chest tube periodically is incorrect as it could lead to a buildup of fluid or air in the pleural space. Keeping the client in a prone position is not necessary for chest drainage, as the positioning may vary depending on the specific situation. Administering diuretics may not be directly related to monitoring the chest tube for proper function and is not a routine intervention for chest tube management post-op.

Correct Answer: A

Rationale: The correct answer is A: Hypertension, high cholesterol, and smoking are major risk factors for stroke. These factors contribute to the development of atherosclerosis, which can lead to a stroke. While obesity and lack of exercise are risk factors for cardiovascular diseases, they are not as directly linked to stroke as hypertension, high cholesterol, and smoking. Family history of cardiovascular disease may increase the overall risk of heart problems, but it is not as specific to stroke as the factors listed in option A. Age and gender can influence the risk of stroke, but they are not modifiable risk factors like hypertension, high cholesterol, and smoking, which can be reduced through lifestyle changes.

Correct Answer: A

Rationale: The correct answer is A: 'Drooping eyelids.' Ptosis, characterized by drooping of the eyelid, is a classic symptom seen in myasthenia gravis. This occurs due to muscle weakness, particularly in the muscles that control eyelid movement. Choice B, 'Unequal pupils,' is not associated with ptosis and may indicate other neurological issues. Choice C, 'Facial twitching,' is not a typical sign of ptosis but could be related to other conditions like nerve irritation. Choice D, 'Facial droop,' is more commonly seen in conditions affecting the facial nerve, like Bell's palsy, and is not a characteristic feature of myasthenia gravis.

Correct Answer: B

Rationale: When a client has a sprained right ankle, they should hold the cane in the opposite hand (left hand) to the affected leg for better support and balance. This positioning helps to reduce the weight on the injured leg while providing stability. Option A is incorrect because advancing the cane too far in front can lead to loss of balance. Option C is incorrect as it does not provide the necessary support for the injured leg. Option D is incorrect as the elbow should be slightly flexed but not necessarily at a specific angle.
