Pathophysiology Final Exam
1. Which physiologic response is most likely to accompany activation of the parasympathetic nervous system?
- A. Increased heart rate
- B. Increased gastric motility
- C. Pupil dilation
- D. Sweating
Correct answer: B
Rationale: The correct answer is B: Increased gastric motility. The parasympathetic nervous system is known to promote rest and digest functions, which includes increasing gastric motility to aid in digestion. Choices A, C, and D are incorrect as they are more characteristic of the sympathetic nervous system. The sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate (Choice A), pupil dilation (Choice C), and sweating (Choice D) among other responses.
2. When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?
- 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 starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy. Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects. Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.
3. A nurse on a postsurgical unit is providing care for a 76-year-old female client who is two days post-hemiarthroplasty (hip replacement) and who states that her pain has been out of control for the last several hours, though she is not exhibiting signs of pain. Which guideline should the nurse use for short-term and long-term treatment of the client's pain?
- A. Pain is what the client says it is, even if she is not exhibiting outward signs.
- B. Pain should be treated only when it is associated with observable symptoms.
- C. Long-term opioid use is generally safe for elderly clients in a hospital setting.
- D. The client's pain should be reassessed after every dose of pain medication.
Correct answer: A
Rationale: Pain is a subjective experience, and the client's report of pain should be taken seriously even if there are no outward signs. Choice B is incorrect because pain can be present without observable symptoms, and waiting for observable signs may delay appropriate pain management. Choice C is incorrect because the safety of long-term opioid use in elderly clients is a complex issue and should be carefully evaluated due to the risk of adverse effects. Choice D is incorrect because while pain reassessment is important, it should not be limited to just after medication administration but should occur regularly to ensure adequate pain control.
4. Which information would indicate more teaching is needed regarding hypersensitivity reactions? Type _______ hypersensitivity reactions involve an antibody response.
- A. I
- B. II
- C. III
- D. IV
Correct answer: D
Rationale: The correct answer is D: Type IV hypersensitivity reactions involve cell-mediated immunity, not an antibody response. This question tests knowledge of hypersensitivity reactions and their classification. Type I hypersensitivity reactions involve IgE antibodies, Type II involves IgG or IgM antibodies, and Type III involves immune complex deposition. Type IV hypersensitivity reactions are delayed and involve T cells, not antibodies. Therefore, if a person believes that Type IV hypersensitivity reactions involve an antibody response, more teaching is required.
5. A female patient is taking combined hormonal contraceptives to prevent pregnancy. She visits the gynecology clinic and is noted to have a blood pressure of 176/102 mm Hg. The patient is started on enalapril mesylate 10 mg. In collaboration with the primary care provider, what other patient teaching should be provided based on her current medication regimen?
- A. Instruct on a low-salt diet.
- B. Instruct to discontinue the contraceptives.
- C. Instruct on the use of relaxation techniques to decrease stress.
- D. Instruct on the rationale for increasing the contraceptive dose.
Correct answer: A
Rationale: Women on hormonal contraceptives and antihypertensives like enalapril should be counseled to adopt a low-salt diet if severe hypertension occurs. This dietary modification can help in managing blood pressure levels. Instructing to discontinue the contraceptives is crucial in cases of severe hypertension as it poses an increased risk of cardiovascular events. Instructing on relaxation techniques may have some benefits in reducing stress levels but addressing the root cause, such as discontinuing contraceptives in this scenario, is more critical. There is no rationale for increasing the contraceptive dose when hypertension is present; in fact, it should be stopped to prevent complications.
