ATI Pathophysiology Exam 2
1. A patient has a heart attack that leads to progressive cell injury resulting in cell death with severe cell swelling and breakdown of organelles. What term would the nurse use to define this process?
- A. Adaptation
- B. Pathologic calcification
- C. Apoptosis
- D. Necrosis
Correct answer: D
Rationale: The correct answer is D: Necrosis. Necrosis is the process of cell death characterized by cell swelling, breakdown of organelles, and eventual rupture, often following ischemic injury like a heart attack. Choices A, B, and C are incorrect. Adaptation refers to the ability of cells to adjust to changes in their environment. Pathologic calcification is the abnormal deposition of calcium salts in tissues. Apoptosis is a programmed cell death that occurs in a controlled, orderly manner.
2. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?
- A. It usually occurs with a headache.
- B. Pupillary changes are common.
- C. It is usually triggered when the patient bends forward.
- D. Nystagmus continues even when eyes fixate on an object.
Correct answer: C
Rationale: Benign positional vertigo is typically triggered by changes in head position, such as bending forward or turning over in bed. This change in position leads to brief episodes of vertigo, often associated with nystagmus, which is rapid, involuntary eye movements. Pupillary changes and headaches are not typical features of benign positional vertigo, making choices B and A incorrect. Nystagmus in benign positional vertigo usually stops when the eyes fixate on an object, so choice D is also incorrect.
3. What is the best way to prevent transmission of infectious agents?
- A. Take antibiotics daily
- B. Call the practitioner for herbal supplements
- C. Wash hands
- D. Avoid public areas as much as possible
Correct answer: C
Rationale: The correct answer is C: Wash hands. Washing hands is the most effective way to prevent the transmission of infectious agents. Antibiotics are not effective in preventing infections, and their overuse can lead to antibiotic resistance. Calling a practitioner for herbal supplements is not a primary method for preventing the transmission of infectious agents. Avoiding public areas entirely is impractical and not as effective as proper hand hygiene.
4. A 25-year-old just had a colonoscopy and was diagnosed with Crohn disease. Which of the following symptoms is consistent with this diagnosis?
- A. Right lower quadrant cramping
- B. Severe bloody diarrhea
- C. Nausea and vomiting
- D. Mostly affects the rectum
Correct answer: A
Rationale: The correct answer is A: Right lower quadrant cramping. Crohn's disease commonly presents with abdominal pain, particularly in the right lower quadrant. Choice B, severe bloody diarrhea, is more characteristic of ulcerative colitis, another type of inflammatory bowel disease. Choice C, nausea and vomiting, are not typical symptoms of Crohn's disease. Choice D is incorrect as Crohn's disease can affect any part of the gastrointestinal tract, not just the rectum.
5. A hemoglobin electrophoresis is done to evaluate for sickle cell disease. The report reveals the person has HbAS, which means the person:
- A. is normal with no sickle cell disease.
- B. is a sickle cell carrier.
- C. has sickle cell anemia.
- D. has thalassemia.
Correct answer: B
Rationale: The correct answer is that the person is a sickle cell carrier. In HbAS, 'Hb' stands for hemoglobin, 'A' indicates normal hemoglobin, and 'S' indicates the sickle cell trait. Individuals with HbAS are carriers of the sickle cell trait but do not have sickle cell disease. Choice A is incorrect because having the sickle cell trait means carrying the gene for sickle cell disease. Choice C is incorrect as sickle cell anemia is a different condition where individuals have two copies of the abnormal hemoglobin gene, resulting in the disease. Choice D is incorrect because thalassemia is a separate genetic disorder affecting the production of hemoglobin, not related to the sickle cell trait.
