Pathophysiology Practice Exam
1. While in an induced coma for 3 weeks, a badly burned firefighter awakens and thanks his son for singing Happy Birthday to him a week earlier. Which part of the brain is responsible for allowing him to hear and comprehend while comatose?
- A. Cerebellum
- B. Thalamus
- C. Temporal lobe
- D. Occipital lobe
Correct answer: C
Rationale: The temporal lobe is responsible for processing auditory information, allowing the patient to hear and comprehend while in a coma. The cerebellum is primarily associated with coordination and balance, not auditory processing. The thalamus serves as a relay station for sensory information but is not specifically responsible for auditory processing. The occipital lobe is mainly involved in processing visual information, not auditory functions.
2. A female patient is prescribed medroxyprogesterone acetate (Provera) for dysfunctional uterine bleeding. What should the nurse include in the patient education?
- A. This medication may cause breakthrough bleeding or spotting.
- B. This medication may cause weight gain.
- C. This medication may increase your risk of developing diabetes.
- D. This medication may increase your risk of breast cancer.
Correct answer: A
Rationale: The correct answer is A. Medroxyprogesterone acetate (Provera) can cause breakthrough bleeding or spotting, which is a common side effect of this medication. Choices B, C, and D are incorrect because weight gain, increased risk of diabetes, and increased risk of breast cancer are not commonly associated side effects of medroxyprogesterone acetate. Therefore, the nurse should focus on educating the patient about the potential for breakthrough bleeding or spotting.
3. In chronic obstructive pulmonary disease, the inflammatory response predominantly involves:
- A. eosinophils
- B. neutrophils
- C. monocytes
- D. cells
Correct answer: B
Rationale: In chronic obstructive pulmonary disease, the inflammatory response predominantly involves neutrophils. Neutrophils play a key role in COPD due to their involvement in initiating and sustaining the inflammatory process. Eosinophils are more commonly associated with asthma rather than COPD. Monocytes are less involved in the inflammatory response in COPD compared to neutrophils. The choice 'cells' is too broad and vague to be a specific answer in this context.
4. What is the process of moving air into the lungs with subsequent distribution to the alveoli called?
- A. Ventilation
- B. Aeration
- C. Enclosure vapor
- D. Residual volume
Correct answer: A
Rationale: The correct answer is A: Ventilation. Ventilation is the process of moving air into the lungs and distributing it to the alveoli for gas exchange. Choice B, Aeration, is not the correct term for this specific process. Choice C, Enclosure vapor, is not related to the movement of air into the lungs. Choice D, Residual volume, refers to the amount of air left in the lungs after maximal expiration and is not the process of moving air into the lungs.
5. A patient presents with a rash from poison ivy. The nurse knows that this is which type of hypersensitivity?
- A. Type I
- B. Type II
- C. Type III
- D. Type IV
Correct answer: D
Rationale: A rash from poison ivy is an example of a type IV hypersensitivity reaction. Type IV hypersensitivity reactions are delayed cell-mediated immune responses involving T cells. This type of reaction is characterized by a delayed onset, typically occurring 48-72 hours after exposure to the antigen. Choice A, Type I hypersensitivity reactions, are immediate hypersensitivity reactions mediated by IgE antibodies. Choices B and C, Type II and Type III hypersensitivity reactions, involve antibody-mediated cytotoxicity and immune complex deposition, respectively, which are not characteristic of poison ivy-induced rashes.
