WGU Pathophysiology Final Exam
1. What is the main function of the mitochondria in a cell?
- A. To produce energy in the form of ATP
- B. To synthesize proteins
- C. To store genetic information
- D. To regulate cell growth
Correct answer: A
Rationale: The correct answer is A: To produce energy in the form of ATP. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This energy is essential for various cellular activities. Choice B is incorrect because protein synthesis primarily occurs in the ribosomes. Choice C is incorrect as the genetic information is stored in the cell's nucleus. Choice D is incorrect as the regulation of cell growth involves various other organelles and processes within the cell.
2. A 30-year-old male was diagnosed with HIV. Which of the following treatments would be most effective?
- A. Reverse transcriptase inhibitors
- B. Protease inhibitors
- C. Entrance inhibitors
- D. Highly active antiretroviral therapy
Correct answer: D
Rationale: The correct answer is D: Highly active antiretroviral therapy (HAART). HAART involves a combination of different classes of antiretroviral drugs, which can effectively suppress the HIV virus, reduce the viral load, and improve the immune function. While choices A, B, and C are also used in HIV treatment, the most effective approach is a combination therapy like HAART due to its ability to target the virus at different stages of its life cycle, reducing the risk of drug resistance and improving treatment outcomes.
3. The college health nurse is providing health education for freshmen. Which of the following pieces of information about immunizations is applicable to individuals of this age group?
- A. The oral polio vaccine should be updated.
- B. The yearly administration of flu vaccine is recommended.
- C. The tetanus toxoid should be within 2 years.
- D. The administration of hepatitis A vaccine is mandatory.
Correct answer: B
Rationale: For freshmen in college, the yearly administration of the flu vaccine is recommended. This is important to protect against seasonal influenza outbreaks that can spread rapidly in close living quarters such as dormitories. Choice A is incorrect as oral polio vaccine is not typically given to individuals of this age group. Choice C is incorrect as tetanus toxoid boosters are usually recommended every 10 years, not within 2 years. Choice D is incorrect as the administration of the hepatitis A vaccine is not mandatory for all individuals in this age group.
4. A patient with endometriosis is prescribed medroxyprogesterone acetate (Provera). What should the nurse include in the patient education?
- A. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
- B. Medroxyprogesterone can be taken with food to reduce gastrointestinal upset.
- C. Medroxyprogesterone should be discontinued if side effects occur.
- D. Medroxyprogesterone should be taken once a week to maintain effectiveness.
Correct answer: A
Rationale: When educating a patient with endometriosis who is prescribed medroxyprogesterone acetate (Provera), the nurse should emphasize the importance of taking the medication at the same time each day. This helps maintain consistent hormone levels and ensures the effectiveness of the treatment. Option A is correct. Option B is incorrect because medroxyprogesterone should be taken consistently, regardless of food intake. Option C is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Option D is incorrect because medroxyprogesterone is typically taken daily, not weekly, for the treatment of endometriosis.
5. Which of the following is a complication of compartment syndrome?
- A. Hemorrhage
- B. Pain and tissue damage
- C. Increased limb function
- D. Chronic kidney disease
Correct answer: B
Rationale: The correct answer is B: Pain and tissue damage. Compartment syndrome occurs due to increased pressure within the muscle compartments, leading to pain and tissue damage. Hemorrhage (choice A) is not a typical complication of compartment syndrome. Increased limb function (choice C) is not a complication but rather a potential improvement if the condition is managed appropriately. Chronic kidney disease (choice D) is unrelated to compartment syndrome.
