Final Exam Pathophysiology
1. If the client's dorsal columns are not functioning, the nurse will observe which response during neuro testing, where the nurse asks the client to close his eyes and then proceeds to touch corresponding parts of the body on each side simultaneously with two sharp points?
- A. The client will not be able to distinguish between the two points.
- B. The client will feel only one point of contact.
- C. The client will accurately identify both points.
- D. The client will report no sensation in the touched areas.
Correct answer: A
Rationale: If the client's dorsal columns are not functioning, the ability to distinguish between two closely spaced points is impaired. This results in the client not being able to differentiate between the two points when touched simultaneously. Choice B is incorrect because the client feeling only one point suggests an intact dorsal column function. Choice C is incorrect as accurately identifying both points indicates normal discrimination ability. Choice D is incorrect as reporting no sensation does not correspond to the specific impairment related to dorsal column dysfunction.
2. A nursing student having trouble moving her head from side to side is likely experiencing a problem with which type of neurons?
- A. General visceral efferent neurons
- B. Preganglionic neurons
- C. Parasympathetic postganglionic neurons
- D. Pharyngeal efferent neurons
Correct answer: D
Rationale: The correct answer is D: Pharyngeal efferent neurons. Pharyngeal efferent neurons are responsible for controlling head movements, including side-to-side motions. General visceral efferent neurons (Choice A) are involved in innervating smooth muscles and glands in the body's internal organs. Preganglionic neurons (Choice B) are part of the autonomic nervous system and connect the central nervous system to the ganglia. Parasympathetic postganglionic neurons (Choice C) are the second neurons in the parasympathetic nervous system pathway, responsible for innervating target organs. In this case, the issue with moving the head from side to side indicates a problem with the pharyngeal efferent neurons.
3. An adult patient has begun treatment with fluconazole. The nurse should recognize the need to likely discontinue the drug if the patient develops which of the following signs or symptoms?
- A. Jaundice
- B. Weight gain
- C. Iron deficiency anemia
- D. Hematuria
Correct answer: A
Rationale: The correct answer is A: Jaundice. Fluconazole, an antifungal medication, can rarely cause hepatotoxicity, which may manifest as jaundice. Monitoring for signs of liver dysfunction, such as jaundice, is crucial during fluconazole therapy. Weight gain, iron deficiency anemia, and hematuria are not commonly associated with fluconazole use and are not indications for discontinuing the drug.
4. In a postmenopausal woman, what condition can be prevented by administering estradiol (Estraderm)?
- A. Endometriosis
- B. Amenorrhea
- C. Osteoporosis
- D. Uterine cancer
Correct answer: C
Rationale: The correct answer is C: Osteoporosis. Estradiol, a form of estrogen, is used to prevent osteoporosis in postmenopausal women by maintaining bone density. Choice A, Endometriosis, is incorrect as estradiol is not used to prevent or treat this condition. Choice B, Amenorrhea, is not prevented by estradiol but rather may result from hormonal changes. Choice D, Uterine cancer, is not directly prevented by estradiol; in fact, long-term unopposed estrogen use can increase the risk of uterine cancer.
5. A patient is receiving epoetin alfa (Epogen) for anemia. Which of the following adjunctive therapies is imperative with epoetin alfa?
- A. Potassium supplements
- B. Sodium restriction
- C. Iron supplement
- D. Renal dialysis
Correct answer: C
Rationale: The correct answer is C: Iron supplement. When a patient is receiving epoetin alfa for anemia, it is imperative to provide iron supplementation as epoetin alfa works by stimulating the production of red blood cells, which require iron for hemoglobin synthesis. Therefore, iron supplementation is crucial to support the increased erythropoiesis. Choices A, B, and D are incorrect because potassium supplements, sodium restriction, and renal dialysis are not typically indicated as adjunctive therapies with epoetin alfa for anemia.
