1. Which of the following are characteristic, localized cardinal signs of acute inflammation? (Select ONE that does not apply.)

• A. Redness
• B. Fatigue
• C. Swelling
• D. Warmth

Correct answer: B

Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.

2. A 17-year-old woman has come to the clinic requesting emergency contraception after having unprotected sex 24 hours ago. What medication is the clinician most likely to prescribe?

• A. Levonorgestrel (Plan B)
• B. Mifepristone (RU-486)
• C. Ulipristal acetate (ella)
• D. Estradiol (Estrace)

Correct answer: A

Rationale: The correct answer is A: Levonorgestrel (Plan B). Levonorgestrel is the most commonly prescribed medication for emergency contraception within 72 hours of unprotected intercourse. It is effective when taken within 72 hours after intercourse, with better efficacy the sooner it is taken. Choice B, Mifepristone (RU-486), is not indicated for emergency contraception but is used for medical abortion. Choice C, Ulipristal acetate (ella), is another option for emergency contraception that is effective up to 120 hours after unprotected intercourse. Choice D, Estradiol (Estrace), is not used for emergency contraception.

3. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?

• A. Ribavirin (Rebetol)
• B. Ganciclovir (Cytovene) IV
• C. Foscarnet (Foscavir) IV
• D. Valganciclovir hydrochloride (Valcyte)

Correct answer: A

Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.

4. Prior to leaving on a backpacking trip to Southeast Asia, a college student has received a tetanus booster shot. This immunization confers protection by way of what immune process?

• A. Passive natural immunity
• B. Active natural immunity
• C. Passive artificial immunity
• D. Active artificial immunity

Correct answer: D

Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.

5. What is the purpose of the inflammatory response?

• A. Prevents blood from entering the injured tissue
• B. Elevates body temperature to prevent spread of infection
• C. Prevents formation of abscess
• D. Minimizes injury and promotes healing

Correct answer: D

Rationale: The inflammatory response is a protective mechanism triggered by tissue damage or infection. It aims to minimize injury by removing harmful stimuli and initiating the healing process. Choice A is incorrect because blood flow to the injured tissue is actually increased to deliver immune cells and nutrients. Choice B is incorrect because while fever is a response to infection, it is not the primary purpose of the inflammatory response. Choice C is incorrect because abscess formation can occur as part of the inflammatory response in an attempt to contain an infection.
