What are the risk factors for the development of pressure ulcers, and how can they be prevented?

Correct Answer: A

Rationale: The correct answer is A: Immobility and poor nutrition are significant risk factors for pressure ulcers. Immobility leads to prolonged pressure on certain body areas, increasing the risk of tissue damage. Poor nutrition can impair skin integrity and the body's ability to heal. Prevention strategies include frequent turning and repositioning to relieve pressure points. Choice B is incorrect because increased mobility actually reduces the risk of pressure ulcers. Choice C is incorrect as excess moisture can contribute to skin breakdown, but it is not a primary risk factor. Choice D is incorrect as frequent turning and repositioning are part of the prevention measures, not risk factors.

Correct Answer: B

Rationale: The correct answer is B because the client should press the button when feeling fetal movement to track the baby's activity. Choice A is incorrect because the client should press the button during movements. Choice C is incorrect as the button should be pressed during fetal movements, not contractions. Choice D is irrelevant to the instructions for the nonstress test.

Correct Answer: B

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures better stability and support for the client while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice C is incorrect as advancing the cane too far with each step may compromise balance. Choice D is incorrect because advancing the cane and the strong leg together may not provide adequate support for the weaker leg.

Correct Answer: A

Rationale: The correct signs of hypovolemic shock are a rapid pulse and low blood pressure. Administering IV fluids helps to restore circulating volume, which is essential in managing hypovolemic shock. Choice B is incorrect because cold extremities and rapid breathing are not typical signs of hypovolemic shock. Choice C is incorrect as administering diuretics would further decrease circulating volume, worsening the condition. Choice D is incorrect as administering vasopressors may further compromise perfusion in hypovolemic shock.

Correct Answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

Correct Answer: C

Rationale: Upon noticing phlebitis at the IV site, the nurse should remove the IV catheter and restart it in another location. Phlebitis is inflammation of the vein, and leaving the IV catheter in place can lead to further complications such as infection. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider immediately (Choice B) is important, but the immediate action to prevent complications is to remove the IV catheter. Monitoring the site for signs of infection (Choice D) is necessary, but the priority action is to remove and reinsert the IV catheter to prevent worsening of the phlebitis.

Correct Answer: B

Rationale: The correct answer is B. Struggling to open a milk carton indicates difficulty with fine motor skills and activities of daily living. This statement suggests a need for assistance from an occupational therapist to improve hand strength, coordination, and independence in performing essential tasks. Choices A, C, and D do not directly relate to the need for occupational therapy services in this context. In contrast, the inability to open a milk carton highlights specific challenges that occupational therapy can address effectively.

Correct Answer: A

Rationale: The correct answer is A. High cholesterol and hypertension are significant risk factors for stroke. Regular exercise is an effective way to prevent stroke by managing these risk factors. Choice B is incorrect as while obesity and smoking are risk factors, preventing stroke through medication and weight loss is not the primary method. Choice C is incorrect as diabetes and alcohol consumption are risk factors, but preventing stroke through regular checkups is not as direct as managing cholesterol and hypertension. Choice D is incorrect as lack of exercise and a poor diet are indeed risk factors, but the prevention of stroke through lifestyle changes needs to specifically address high cholesterol and hypertension.

Correct Answer: B

Rationale: The correct answer is to irrigate the NG tube with sterile water. When a client with an NG tube attached to low suctioning becomes nauseated and there is a decrease in the flow of gastric secretions, it indicates a possible blockage in the tube. Irrigating the tube with sterile water can help clear the blockage, allowing for proper suctioning and relieving the client's nausea. Increasing the suction pressure (Choice A) can further worsen the issue by potentially causing harm to the client. Turning the client on their side (Choice C) may not address the underlying problem of tube blockage. Replacing the NG tube with a new one (Choice D) should only be considered if other interventions, like irrigation, fail to clear the blockage.
