A nurse is reviewing the medical record of a client with dementia who frequently becomes agitated. What should the nurse prioritize?

Correct Answer: B

Rationale: The correct answer is to investigate the client's recent medication changes. In a client with dementia who frequently becomes agitated, medication changes can often be a significant factor contributing to their behavior. Checking recent medication changes can help identify if any specific medication is causing or exacerbating the agitation. Choice A about fluid and electrolyte balance is less likely to be the priority unless there are specific indications in the medical record. Choice C, investigating recent changes in cognitive functioning, may be important but addressing the agitation first is a more immediate concern. Choice D, investigating the client's psychosocial environment, is also important but may not directly address the immediate cause of the agitation as medication changes could.

Correct Answer: B

Rationale: The correct initial action when a client with a tracheostomy exhibits respiratory distress is to suction the tracheostomy. This helps to clear secretions and improve the client's ability to breathe. Notifying the provider (choice A) can cause a delay in immediate intervention. Administering a bronchodilator (choice C) may be necessary but is not the priority in this situation. Increasing the oxygen flow rate (choice D) can be helpful but should come after addressing the immediate need for suctioning to clear the airway.

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.
