A healthcare provider is providing discharge instructions to a client with home oxygen. What is the most important safety consideration?

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 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.

Correct Answer: C

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care to a client with a pressure ulcer. This action helps identify any underlying infections, allowing healthcare providers to select the most appropriate treatment. Options A, B, and D are not as critical as performing a wound culture, as they focus on wound dressing and cleansing rather than identifying potential infections.

Correct Answer: D

Rationale: The nurse should prioritize performing a wound culture before administering antibiotics to ensure appropriate treatment. This step helps identify the specific infecting organism and its susceptibility to different antibiotics, guiding effective antibiotic therapy. Changing the dressing daily (Choice A) is important but comes after assessing the infection and initiating appropriate treatment. Cleansing the wound with an antiseptic solution (Choice B) and applying a wet-to-dry dressing (Choice C) are interventions that may be necessary but are secondary to determining the most suitable antibiotic therapy based on the wound culture results.
