A nurse is caring for an older adult client with delirium. Which intervention will most effectively reduce the client's risk for falls?

Correct Answer: D

Rationale: Hourly rounding by the nurse is the most effective intervention to reduce the risk of falls in older adult clients with delirium. This intervention ensures that the nurse regularly checks on the client, assesses their needs, and assists them with any activities, thereby minimizing the chances of falls. Using a night-light (choice A) may help improve visibility but does not provide continuous assistance and monitoring. Demonstrating how to use the call light (choice B) is important but may not prevent falls directly. Placing the bedside table in close proximity (choice C) is helpful for convenience but does not address the continuous monitoring and assistance needed to prevent falls in this case.

Correct Answer: A

Rationale: The correct answer is A. Trazodone can cause sedation, so clients should be cautioned about activities requiring alertness, like driving. Choice B is incorrect because trazodone is not a stimulant; it is actually a sedating antidepressant. Choice C is incorrect as all medications have potential side effects. Choice D is not specifically indicated for trazodone; the client should follow the prescribing healthcare provider's instructions regarding food intake.

Correct Answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

Correct Answer: A

Rationale: The correct answer is to check potassium levels before administering furosemide. Furosemide is a diuretic that can cause hypokalemia (low potassium levels) as a side effect. Monitoring potassium levels is crucial to prevent potential complications related to electrolyte imbalance. Assessing blood glucose levels (choice B) is not directly related to furosemide administration. Monitoring respiratory rate (choice C) is important in certain situations, but it is not the priority before administering furosemide. Administering furosemide with food (choice D) is not a requirement as it can be administered regardless of meals.

Correct Answer: A

Rationale: Corrected Rationale: Prednisone is known to cause hyperglycemia by increasing blood glucose levels. Monitoring blood glucose levels is crucial to detect and manage any potential hyperglycemic effects of prednisone. While prednisone can also affect serum potassium levels and liver function, the priority monitoring parameter in this case is blood glucose levels. Monitoring heart rate is not directly associated with prednisone administration, making it a less relevant parameter to monitor in this scenario.

Correct Answer: A

Rationale: The correct answer is A: 'It can cause dependency.' Lorazepam is a benzodiazepine known to cause dependency, so it is crucial for clients to be informed about this potential risk. Choice B is incorrect as combining lorazepam with alcohol can lead to increased sedation and other adverse effects. Choice C is incorrect because lorazepam, like any medication, can have side effects such as drowsiness, dizziness, or confusion. Choice D is also incorrect as lorazepam is a sedative-hypnotic medication, not a stimulant.

Correct Answer: B

Rationale: The correct answer is B: 'Organize an immunization clinic for at-risk members of the community.' The assurance function of public health involves ensuring that essential public health services, like immunizations, are provided to meet public health goals. Choice A, collecting data on health trends, is more aligned with the assessment function of public health. Choice C, developing policies to address health disparities, pertains to the policy development function. Choice D, conducting research on communicable diseases, is related to the research function rather than the assurance function.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to begin CPR. Even though the living will requests no resuscitation, without a written do-not-resuscitate (DNR) order from the provider, the nurse is ethically and legally bound to initiate CPR to provide life-saving measures until further confirmation is obtained. Notifying the family (Choice A) may cause a delay in providing immediate care. Waiting for further instructions (Choice C) can be time-consuming and compromise patient outcomes. Documenting the event (Choice D) is important but should follow after initiating CPR to ensure patient safety and adherence to protocols.

Correct Answer: B

Rationale: The correct answer is to assess blood pressure first. Enalapril is an ACE inhibitor commonly used to manage hypertension. It is crucial to evaluate the patient's blood pressure before administering enalapril to ensure it is within safe limits. Assessing other parameters like heart rate, serum creatinine, and potassium levels is also important but assessing blood pressure takes precedence due to the medication's mechanism of action and potential effects on blood pressure regulation.
