When should elastic stockings be applied?

Correct Answer: B

Rationale: The correct answer is B: In the morning. Elastic stockings should be applied in the morning when the leg swelling is at its minimum. This ensures optimal compression effectiveness throughout the day when the individual is most active. Applying them in the evening (choice A) may lead to discomfort due to increased swelling during the day. Mid-afternoon (choice C) is not ideal as it may miss the opportunity to provide consistent compression. Applying them after exercising (choice D) may not be effective as the swelling may already be present.

Correct Answer: C

Rationale: The correct answer is C: Mark the bathroom with a sign or picture. This is important because individuals with Alzheimer's disease may have difficulty recognizing familiar surroundings, leading to confusion and accidents. By marking the bathroom with a sign or picture, the resident can easily identify the location and purpose of the room, reducing the likelihood of accidents. A: Withholding fluids is not appropriate as it can lead to dehydration and other health issues. B: Dimming the bathroom lights may further confuse the resident and increase the risk of accidents. D: The answer choice is incomplete, so it cannot be evaluated for correctness. In summary, marking the bathroom with a sign or picture is the best choice as it helps the resident with Alzheimer's disease navigate the environment safely and independently.

Correct Answer: A

Rationale: The correct answer is A because it is a well-documented fact that the immune system tends to weaken with age, leading to decreased effectiveness in fighting off infections and diseases. This decline is due to factors such as thymus shrinkage and decreased T-cell function. Antibody response speeding up (B) and increased T-cells (C) are not typical age-related changes. Response to vaccines increasing (D) is also unlikely as older individuals usually have a weakened immune response to vaccines.

Correct Answer: B

Rationale: The correct answer is B: Intubation. Intubation is the process of inserting a tube into the airway to help with breathing. It is a specific procedure used to secure an artificial airway for patients who are unable to maintain their own airway. Telemetry (A) is a method of monitoring and transmitting data wirelessly, not related to airway insertion. Ventilation (C) refers to the movement of air in and out of the lungs, not the method of inserting an artificial airway. Dyspnea (D) is a term used to describe difficulty breathing, not the method of inserting an artificial airway.

Correct Answer: C

Rationale: The correct answer is C (15 hours) because federal regulations mandate nursing assistants to complete 12 hours of continuing education annually. This requirement ensures that nursing assistants are up-to-date with the latest practices, guidelines, and skills necessary to provide high-quality care to patients. Explanation for other choices: A (10 hours): This choice is incorrect as it does not meet the federal requirement of 12 hours. B (12 hours): While this choice aligns with the federal requirement, it falls short of the correct answer of 15 hours. D (18 hours): This choice exceeds the federal requirement and is therefore incorrect.
