ATI Pathophysiology Exam 2
1. Although stress exposure initiates integrated responses by multiple systems, which system first activates the most important changes?
- A. Pulmonary
- B. Gastrointestinal
- C. Neuroendocrine
- D. Cardiovascular
Correct answer: C
Rationale: The correct answer is C, the Neuroendocrine system. When the body is exposed to stress, the neuroendocrine system plays a crucial role in initiating the body's response. This system, particularly through the hypothalamic-pituitary-adrenal axis, triggers a cascade of physiological responses to stress. Choices A, B, and D are incorrect because while other systems like the cardiovascular and gastrointestinal systems also respond to stress, the neuroendocrine system is primarily responsible for the initial and significant changes in the body's stress response.
2. When administering an immunization, which of the following medications should be available?
- A. Diphenhydramine (Benadryl)
- B. Hydroxyzine (Vistaril)
- C. Physostigmine
- D. Epinephrine
Correct answer: D
Rationale: When administering an immunization, it is essential to have epinephrine available in case of an allergic reaction such as anaphylaxis. Epinephrine is the medication of choice for treating severe allergic reactions due to its ability to reverse the symptoms rapidly. Diphenhydramine and hydroxyzine are antihistamines that can help manage mild allergic reactions but are not the primary medications for severe reactions like anaphylaxis. Physostigmine is not indicated for managing allergic reactions and is used for specific conditions such as anticholinergic toxicity.
3. A 20-year-old college student has presented to her campus medical clinic for a scheduled Pap smear. The clinician who will interpret the smear will examine cell samples for evidence of:
- A. Changes in cell shape, size, and organization
- B. Presence of unexpected cell types
- C. Ischemic changes in cell sample
- D. Abnormally high numbers of cells
Correct answer: A
Rationale: The correct answer is changes in cell shape, size, and organization (Choice A). Pap smears are performed to detect potential precancerous or cancerous conditions by examining the cells for any abnormalities in their shape, size, or organization. This helps in identifying early signs of cervical cancer. Choices B, C, and D are incorrect because Pap smears primarily focus on detecting cellular changes associated with cancer, not unexpected cell types, ischemic changes, or abnormally high numbers of cells.
4. A 58-year-old woman comes to the clinic for evaluation of a sharp, intermittent, severe, stabbing facial pain that she describes as 'like an electric shock.' The pain occurs only on one side of her face; it seems to be triggered when she chews, brushes her teeth, or sometimes when she merely touches her face. There is no numbness associated with the pain. What is most likely causing her pain?
- A. Temporal arteritis
- B. Trigeminal neuralgia
- C. Migraine headache
- D. Cluster headache
Correct answer: B
Rationale: The correct answer is B: Trigeminal neuralgia. Trigeminal neuralgia is characterized by severe, stabbing pain in the distribution of the trigeminal nerve, often triggered by light touch, chewing, or brushing teeth. In this case, the patient's symptoms of sharp, intermittent facial pain triggered by activities like chewing and touching her face are classic for trigeminal neuralgia. Choices A, C, and D are incorrect. Temporal arteritis typically presents with unilateral headache, jaw claudication, and visual symptoms. Migraine headaches are usually throbbing in nature and often associated with nausea, vomiting, and sensitivity to light and sound. Cluster headaches are characterized by severe unilateral pain around the eye with autonomic symptoms like lacrimation and nasal congestion.
5. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse teach the patient about the use of this medication?
- A. Medroxyprogesterone should be taken with food to prevent nausea.
- B. Medroxyprogesterone can be taken intermittently when symptoms worsen.
- C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
- D. Medroxyprogesterone should be discontinued if side effects occur.
Correct answer: C
Rationale: The correct answer is C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Taking it at different times can lead to hormonal fluctuations and reduced medication efficacy. Choice A is incorrect because medroxyprogesterone does not need to be taken with food to prevent nausea. Choice B is incorrect as medroxyprogesterone is typically taken continuously rather than intermittently. Choice D is incorrect because side effects should be reported to the healthcare provider for further evaluation and management, not automatically leading to discontinuation of the medication.
