WGU Pathophysiology Final Exam
1. When a healthcare professional notices that a patient has type O blood, they realize that anti-_____ antibodies are present in the patient's body.
- A. A only
- B. B only
- C. A and B
- D. O
Correct answer: C
Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens. Therefore, the correct answer is C. Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies. Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.
2. When the maternal immune system becomes sensitized against antigens expressed by the fetus, what type of immune reaction occurs?
- A. Autoimmune
- B. Anaphylaxis
- C. Alloimmune
- D. Allergic
Correct answer: C
Rationale: When the maternal immune system becomes sensitized against antigens expressed by the fetus, an alloimmune reaction occurs. In this situation, the mother's immune system recognizes the fetus as foreign due to differences in antigens, leading to an immune response against the fetus. Choice A, 'Autoimmune,' is incorrect because it refers to the immune system mistakenly attacking the body's own cells and tissues. Choice B, 'Anaphylaxis,' is not the correct answer as it is a severe allergic reaction that can be life-threatening. Choice D, 'Allergic,' is also incorrect as it refers to an immune response triggered by allergens, not antigens expressed by the fetus.
3. What specific instructions should the nurse provide for a patient starting on alendronate (Fosamax) for osteoporosis to ensure proper administration?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
- B. Take the medication with milk to enhance calcium absorption.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with food to prevent nausea.
Correct answer: A
Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because alendronate should not be taken with milk, as it can interfere with its absorption. Choice C is incorrect as there is no specific instruction to take alendronate at bedtime. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.
4. Which of the following would the nurse expect to see in a client experiencing hypoventilation?
- A. Increased oxygenation in the alveoli
- B. Increased carbon dioxide in the bloodstream
- C. Decreased hemoglobin in the bloodstream
- D. Decreased carbon dioxide in the alveoli
Correct answer: B
Rationale: In hypoventilation, there is inadequate ventilation leading to decreased removal of carbon dioxide. This results in increased carbon dioxide in the bloodstream. The other choices are incorrect because hypoventilation does not improve oxygenation in the alveoli (Choice A), decrease hemoglobin in the bloodstream (Choice C), or decrease carbon dioxide in the alveoli (Choice D).
5. How often should a patient be administered a tetanus toxoid?
- A. Every year
- B. Every 10 years
- C. Every 2 years
- D. Every 5 years
Correct answer: B
Rationale: Tetanus toxoid should be administered every 10 years to ensure continued protection against tetanus infection. The correct answer is 'Every 10 years.' Choice A ('Every year') is incorrect as the frequency is too frequent. Choice C ('Every 2 years') is incorrect as it is too frequent for tetanus toxoid administration. Choice D ('Every 5 years') is incorrect as it does not align with the recommended interval for tetanus toxoid booster doses.
