A nurse is educating a client on how to use a cane due to left-leg weakness. What should the nurse include in the teaching?

Correct Answer: A

Rationale: The correct answer is to use the cane on the stronger side. By doing so, the client will have better support and balance. Choice B is incorrect because advancing the cane and the weaker leg at the same time may lead to instability and falls. Choice C is incorrect as using the cane on the weaker side does not provide optimal support. Choice D is incorrect as advancing the cane 30 to 45 cm (12-18 in) with each step is not a standard recommendation for cane use.

Correct Answer: B

Rationale: The best strategy to promote independence in self-care for a client concerned about extreme fatigue after an acute myocardial infarction is to instruct the client to gradually resume self-care tasks, with rest periods. This approach allows the client to regain independence without overexerting. Choice A is incorrect because encouraging the client to rest completely and letting the healthcare team take over self-care tasks may hinder independence. Choice C is incorrect as assigning assistive personnel to complete self-care tasks does not promote the client's independence. Choice D is not the best option as the primary focus should be on empowering the client to perform self-care tasks independently.

Correct Answer: C

Rationale: The correct answer is to keep oxygen tanks upright at all times. This is essential for safety as it prevents the tanks from falling and causing injury. Allowing the client to smoke in designated outdoor areas (Choice A) is unsafe as smoking near oxygen equipment can lead to a fire. Placing the oxygen equipment 10 feet away from any open flames (Choice B) is important to prevent fire hazards, but keeping the tanks upright is more directly related to preventing injuries. Restricting fluid intake while using oxygen (Choice D) is not necessary for safety in home oxygen therapy.

Correct Answer: B

Rationale: Irritability is an early sign that suctioning is needed for a client with a tracheostomy. When secretions accumulate in the airway, it can lead to discomfort and irritability in the client. Bradycardia, hypotension, and decreased oxygen saturation are usually later signs of inadequate airway clearance and oxygenation. Bradycardia may indicate severe hypoxia, while hypotension and decreased oxygen saturation are consequences of prolonged airway obstruction.

Correct Answer: B

Rationale: The correct instruction when using a cane due to leg weakness is to maintain two points of support on the floor at all times. This provides stability and support while walking. Choice A is incorrect because the cane should be used on the weaker side to provide assistance. Choice C is incorrect as the cane and weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.
