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. In which of the following cases is dehydration more likely to occur?
- A. A 50-year-old woman who is a bodybuilder
- B. A 50-year-old man who is morbidly obese
- C. A 10-year-old child who is thin
- D. A 30-year-old with multiple sclerosis
Correct answer: B
Rationale: The correct answer is B. Morbid obesity increases the risk of dehydration due to the larger body surface area and potential for greater insensible losses. Choices A, C, and D are less likely to experience dehydration compared to a morbidly obese individual.
3. When starting on oral contraceptives, what should the nurse include in the education regarding the timing of the medication?
- A. Oral contraceptives should be taken at the same time each day to maintain stable hormone levels and prevent pregnancy.
- B. Oral contraceptives can be taken at any time of day, as long as the schedule is consistent.
- C. Oral contraceptives should be taken in the morning to avoid nighttime side effects.
- D. Oral contraceptives are effective immediately upon starting, regardless of timing.
Correct answer: A
Rationale: When educating a patient starting on oral contraceptives, it is essential to stress the importance of taking the medication at the same time each day. This ensures stable hormone levels, improving the effectiveness of the contraceptives in preventing pregnancy. Choice B is incorrect because consistency in timing is crucial for maintaining hormone levels. Choice C is incorrect as there is no specific requirement to take oral contraceptives in the morning to avoid side effects. Choice D is incorrect as oral contraceptives may take some time to become fully effective, and consistent timing is important for their efficacy.
4. During patient teaching, a young woman asks the nurse the following question: 'If I get pregnant on the 'pill,' should I continue to take it?' What is the nurse's best response?
- A. The pill has no effect on pregnancy.
- B. The pill will cause miscarriage.
- C. This is a personal choice for each woman.
- D. The pill can be harmful to the fetus and should be discontinued.
Correct answer: C
Rationale: The correct answer is 'C: This is a personal choice for each woman.' If a woman becomes pregnant while taking birth control pills, it is generally recommended to discontinue them as they can potentially harm the fetus. However, the decision to continue or discontinue the pill in case of pregnancy is ultimately a personal choice for each woman. Choice A is incorrect because birth control pills are meant to prevent pregnancy, but if a woman becomes pregnant while taking them, the situation changes. Choice B is incorrect because birth control pills do not cause miscarriage; they are intended to prevent pregnancy. Choice D is incorrect because while it is generally advised to discontinue the pill if pregnancy occurs, the decision ultimately depends on the individual circumstances and preferences of the woman.
5. Which of the following is a characteristic of disseminated intravascular coagulation (DIC)?
- A. Simultaneous stroke and heart attack
- B. Simultaneous clotting and bleeding
- C. Simultaneous clotting and insulin release
- D. Simultaneous bleeding and vomiting
Correct answer: B
Rationale: Disseminated intravascular coagulation (DIC) is characterized by simultaneous clotting and bleeding throughout the body. This imbalance in the body's clotting system leads to the formation of blood clots in small blood vessels, which can consume clotting factors and platelets, ultimately leading to excessive bleeding. Choices A, C, and D are incorrect because they do not describe the characteristic feature of DIC, which involves both clotting and bleeding.
