A nurse is providing discharge instructions to a client with home oxygen therapy. What safety measure should the nurse emphasize?

Correct Answer: B

Rationale: The correct safety measure that the nurse should emphasize is to keep oxygen tanks upright and away from heat sources. This is crucial to prevent the risk of fire or explosion. Choice A is incorrect as smoking near oxygen can lead to a fire hazard. Choice C is also incorrect as storing oxygen tanks in enclosed spaces can be dangerous. Choice D, although related to safety, does not address the immediate risk of keeping oxygen tanks away from heat sources.

Correct Answer: B

Rationale: The correct answer is to ensure oxygen tanks are kept upright and away from heat sources. This is crucial to prevent any potential fire hazard, as oxygen supports combustion. Restricting fluid intake while using oxygen (choice A) is not necessary for oxygen safety. Allowing family members to smoke in designated areas (choice C) poses a significant fire risk. Storing oxygen tanks in a closet when not in use (choice D) is unsafe because proper ventilation is needed to prevent oxygen accumulation.

Correct Answer: A

Rationale: The correct answer is to maintain a calm manner. When managing a client with severe anxiety, the nurse's calm presence can help the client feel more secure and reduce their anxiety levels. It is essential to create a safe and supportive environment. Helping the client identify thoughts prior to anxiety (choice B) may be beneficial in cognitive-behavioral interventions but may not be the initial best action for severe anxiety. Administering anti-anxiety medication (choice C) should be done by a healthcare provider's order and is not the first-line intervention for managing severe anxiety. Initiating seclusion (choice D) should only be considered as a last resort if the client is at risk of harm to themselves or others, as it can further escalate anxiety and should not be the initial action.

Correct Answer: A

Rationale: The correct answer is to administer insulin. In hyperglycemia, there is an excess of glucose in the blood, which needs to be lowered. Insulin is the primary medication used to lower blood glucose levels by facilitating the uptake of glucose into cells. Encouraging the client to exercise may further increase blood glucose levels due to the release of stress hormones, so it is not the priority. While staying hydrated is important, it will not directly address the high blood glucose levels seen in hyperglycemia. Glucagon is used to treat severe hypoglycemia, not hyperglycemia, so it is not the priority in this situation.

Correct Answer: B

Rationale: The correct answer is B - 'Identify the underlying causative condition.' When a client is experiencing delirium, it is crucial to determine the root cause of this acute change in mental status. This can involve a thorough assessment to identify any medical conditions, medications, infections, or environmental factors that may be contributing to the delirium. By pinpointing the underlying cause, appropriate interventions can be implemented to address the specific issue. Choices A, C, and D are incorrect because controlling behavioral symptoms with low-dose psychotropics, increasing environmental stimulation, and administering antipsychotic medication do not target the primary need of identifying and addressing the causative condition of delirium.
