Pathophysiology Practice Exam
1. What should the nurse include in patient education regarding the effectiveness of oral contraceptives?
- A. Oral contraceptives are highly effective when taken correctly but not 100% foolproof.
- B. Oral contraceptives may take some time to reach full effectiveness after starting.
- C. Oral contraceptives can be less effective if taken with certain antibiotics.
- D. Taking oral contraceptives with food does not significantly affect their efficacy.
Correct answer: C
Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics due to potential drug interactions that may reduce contraceptive efficacy. It is crucial for patients to be aware of this to consider additional contraceptive measures when prescribed antibiotics. Choice A is incorrect because while oral contraceptives are highly effective when taken correctly, they are not 100% foolproof. Choice B is incorrect as oral contraceptives may take some time to reach their full effectiveness after starting. Choice D is also incorrect as taking oral contraceptives with food does not significantly affect their efficacy.
2. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?
- A. Maternally derived iron stores are depleted in the first 2 months.
- B. Fetal hemoglobin results in a shortened survival of red blood cells.
- C. The production of adult hemoglobin decreases in the first year of life.
- D. Low levels of fetal hemoglobin depress the production of erythropoietin.
Correct answer: B
Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.
3. When starting therapy with Lisinopril, a client should be instructed to monitor for which of the following adverse effects?
- A. Tinnitus
- B. Diarrhea
- C. Cough
- D. Weight gain
Correct answer: C
Rationale: The correct answer is C: Cough. Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. Clients should be informed to monitor for this side effect and report it to their healthcare provider if it occurs. Choices A, B, and D are incorrect because tinnitus, diarrhea, and weight gain are not commonly associated with Lisinopril therapy.
4. Which of the following vaccines is not done by intramuscular (IM) injection?
- A. Measles vaccine C. Hepa-B vaccine
- B. DPT D. Tetanus toxoids
- C.
- D.
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
5. What does the PR interval measure?
- A. Time it takes for the electrical impulse to travel from the atria to the ventricles
- B. Measurement of ventricular depolarization
- C. Duration of ventricular repolarization
- D. Segment representing the time between ventricular depolarization and repolarization
Correct answer: A
Rationale: The PR interval measures the time it takes for the electrical impulse to travel from the atria to the ventricles. It is crucial in diagnosing heart rhythm disorders, as abnormalities in this interval can indicate conduction abnormalities between the atria and ventricles. Choices B, C, and D are incorrect. The QRS complex represents ventricular depolarization, the QT interval represents the duration of ventricular repolarization, and the ST segment represents the time between ventricular depolarization and repolarization.
