Correct Answer: C

Rationale: The correct answer is C: Disorganized speech. Disorganized speech is a hallmark symptom of schizophrenia, characterized by impaired thought processes that lead to incoherent, disjointed communication. All-or-nothing thinking (Choice A) is more commonly associated with cognitive distortions seen in conditions like anxiety disorders. Euphoric mood (Choice B) is not a typical finding in schizophrenia, as individuals with this disorder often display a flat or blunted affect. Hypochondriasis (Choice D) involves a preoccupation with having a serious illness and is not a primary symptom of schizophrenia.

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: 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: D

Rationale: In cases of anaphylaxis, all of the listed interventions are crucial for effective management. Administering epinephrine is the primary treatment to reverse the allergic reaction rapidly. Providing oxygen ensures adequate oxygenation to vital organs, and monitoring the airway is essential to prevent obstruction and maintain a clear air passage. Therefore, all three interventions are necessary in managing anaphylaxis. Choices A, B, and C are not individually sufficient to address all aspects of anaphylaxis, making the comprehensive approach of 'All of the above' the correct answer.

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.
