1. Which type of isolation is required for a patient with measles?

• A. Contact isolation
• B. Airborne isolation
• C. Droplet isolation
• D. Reverse isolation

Correct answer: B

Rationale: The correct answer is B: Airborne isolation. Measles is highly contagious and can be transmitted through airborne particles, so airborne isolation is necessary to prevent its spread. Choice A, Contact isolation, is incorrect because measles is not primarily transmitted through direct contact. Choice C, Droplet isolation, is also incorrect as measles is not transmitted through large droplets but through smaller airborne particles. Choice D, Reverse isolation, is used to protect a patient from outside infections, not to prevent the spread of a contagious disease like measles.

2. Which condition is most commonly associated with a "bull's eye" rash?

• A. Lyme disease
• B. Rocky Mountain spotted fever
• C. Syphilis
• D. Toxoplasmosis

Correct answer: A

Rationale: The correct answer is A: Lyme disease. The "bull's eye" rash, or erythema migrans, is a hallmark of early Lyme disease, caused by the bacterium Borrelia burgdorferi. Choice B, Rocky Mountain spotted fever, presents with a different type of rash. Choice C, Syphilis, typically presents with a painless ulcer and rash but not a "bull's eye" rash. Choice D, Toxoplasmosis, does not typically present with a "bull's eye" rash.

3. Which of the following best describes the role of insulin in the body?

• A. Insulin helps break down glucose into energy for the body
• B. Insulin facilitates the movement of glucose into cells
• C. Insulin converts excess glucose into fat for storage
• D. Insulin increases the breakdown of protein into amino acids

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

4. A client with peripheral neuropathy due to cirrhosis is at risk for injury. What should the nurse do?

• A. Protect the client's feet from injury
• B. Apply a heating pad to the affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct answer: A

Rationale: Protecting the client's feet from injury is critical as peripheral neuropathy can lead to decreased sensation and increased risk of trauma. This measure helps prevent wounds, ulcers, and other complications. Applying a heating pad (Choice B) can worsen symptoms and cause burns due to decreased sensation. Keeping the client's feet elevated (Choice C) may help reduce swelling but does not directly address the risk of injury. Assessing for jaundice (Choice D) is important in cirrhosis but is not directly related to the client's risk of injury due to peripheral neuropathy.

5. A client with a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management asks how it works. What information should the nurse reinforce?

• A. The discharge of electricity will distract the client's focus from the pain
• B. An infusion of medication in the spinal canal will block pain perception
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus that can block pain signals from reaching the brain, effectively reducing the perception of pain. Choice A is incorrect because TENS does not distract from pain but rather interferes with pain signals. Choice B is incorrect as TENS does not involve infusing medication into the spinal canal. Choice C is also incorrect because TENS does not target the cerebral cortex to dull pain perception but rather works at the level of nerve conduction.
