1. Which of the following disorders is more likely associated with blood in stool?

• A. Gastroesophageal reflux
• B. Crohn's disease
• C. Irritable bowel syndrome
• D. Colon cancer

Correct answer: D

Rationale: Colon cancer is more likely associated with blood in stool due to the presence of bleeding from the tumor in the colon. Gastroesophageal reflux (Choice A) typically presents with heartburn and regurgitation but not blood in stool. Crohn's disease (Choice B) can cause gastrointestinal symptoms, but bloody stools are more commonly associated with ulcerative colitis. Irritable bowel syndrome (Choice C) is characterized by abdominal pain, bloating, and changes in bowel habits, but it does not typically cause blood in stool. Therefore, the correct answer is D, Colon cancer.

2. A patient has been using Viagra on an intermittent basis for several years. However, he has cited delays in the onset and peak of action as the occasional source of frustration. What PDE5 inhibitor may be of particular benefit to this patient's needs?

• A. Avanafil (Stendra)
• B. Tadalafil (Cialis)
• C. Vardenafil (Levitra)
• D. Alprostadil (Caverject)

Correct answer: A

Rationale: The correct answer is Avanafil (Stendra). Avanafil has a rapid onset of action compared to other PDE5 inhibitors, making it suitable for patients experiencing delays in onset and peak of action with other medications like Viagra. Tadalafil (Cialis), Vardenafil (Levitra), and Alprostadil (Caverject) do not offer the same rapid onset of action as Avanafil, making them less suitable for addressing the specific needs of this patient.

3. Which immunoglobulin is the first to appear in response to a new antigen?

• A. IgA
• B. IgG
• C. IgE
• D. IgM

Correct answer: D

Rationale: The correct answer is IgM. IgM is the first immunoglobulin to appear in response to a new antigen. It is produced initially during the primary immune response. IgA is mainly found in mucosal areas and secretions. IgG is produced in a secondary immune response and is the most abundant immunoglobulin in the bloodstream. IgE is involved in allergic reactions and parasitic infections, not the initial response to a new antigen.

4. Stress-induced cortisol hormone secretion is associated with:

• A. Increased growth hormone level
• B. Regulation of the stress response
• C. Increased thyroid-stimulating hormone
• D. Depressed adrenal gland function

Correct answer: B

Rationale: The correct answer is B: Regulation of the stress response. Cortisol plays a crucial role in regulating the body's response to stress by modulating various physiological processes. Choices A, C, and D are incorrect because stress-induced cortisol hormone secretion is not directly associated with increased growth hormone levels, increased thyroid-stimulating hormone, or depressed adrenal gland function.

5. 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.
