The medical term cyanosis means

Correct Answer: D

Rationale: The correct answer is D: Blue-tinged skin and mucous membranes due to a decrease of oxygen in the system. Cyanosis is the bluish discoloration of the skin and mucous membranes caused by inadequate oxygen levels in the blood. This occurs because when blood lacks oxygen, it appears bluer when seen through the skin. The other choices are incorrect because cyanosis is not related to an increase in oxygen (choice A), poisoning (choice B), or bacterial increase in the respiratory system (choice C). The key to understanding the correct answer lies in knowing the physiological basis of cyanosis and its association with oxygen levels in the blood.

Correct Answer: B

Rationale: The correct answer is B: Improved circulation. Regular ambulation, or walking, helps to increase blood flow throughout the body, which in turn enhances circulation. This is beneficial for overall health as it improves oxygen and nutrient delivery to tissues and organs. Increased circulation also helps in removing waste products and toxins from the body. Choice A: Decreased sleep - Regular ambulation is not directly linked to decreased sleep. In fact, physical activity can promote better sleep quality. Choice C: Reduced oxygen level - Regular ambulation actually increases oxygen levels in the body due to improved circulation. Choice D: Slower elimination - Regular ambulation can actually aid in promoting regular bowel movements and faster elimination due to the movement stimulating the digestive system.

Correct Answer: D

Rationale: The correct answer is D: Widen or open. Dilation refers to the process of expanding or enlarging an object. When an object is dilated, its size increases but its shape remains the same. This term is commonly used in geometry to describe the transformation of stretching or shrinking a shape. In contrast, choices A, B, and C are incorrect because they describe actions that involve reducing the size or changing the speed of an object, which is not the definition of dilation.

Correct Answer: C

Rationale: The correct answer is C: Urostomy. This surgical procedure diverts the passage of urine by creating a stoma through the abdominal wall to allow urine to exit the body. Colostomy (A) diverts feces, Ileostomy (B) diverts small intestine contents, and Gastrostomy (D) creates an opening for feeding tube placement. Urostomy specifically addresses diverting urine flow.

Correct Answer: C

Rationale: The correct answer is C: Continuous bladder irrigation. This procedure involves continuously flushing the bladder with a sterile solution to prevent blood clot formation and maintain catheter patency post-surgery. It helps in monitoring urine output and preventing urinary retention. A: Indwelling catheter care involves routine maintenance of the catheter but does not involve continuous flushing. B: Straight catheterization is a one-time procedure to empty the bladder, not for continuous flushing. D: Bladder retraining is a process to improve bladder control, not related to post-operative catheter care.
