ATI Pathophysiology Final Exam

Correct Answer: A

Rationale: When a patient taking an oral contraceptive misses one pill, the correct action is to take two pills as soon as they remember and then continue the regular schedule. Option A is the correct answer because doubling up the dose helps maintain the effectiveness of the contraceptive. Option B is incorrect because taking only one pill after missing one may decrease contraceptive effectiveness. Option C is wrong as skipping the missed pill can also reduce effectiveness. Option D is inaccurate because taking two pills immediately is not necessary; the patient should take the missed pill as soon as remembered and then resume the regular dosing schedule.

Correct Answer: A

Rationale: The correct answer is A because Guillain-Barr� syndrome is an acute immune-mediated polyneuropathy that can lead to paralysis affecting movement on both sides of the body, and in severe cases, involving the respiratory muscles. Choice B is incorrect as it describes local swelling, not the systemic effects of Guillain-Barr� syndrome. Choice C is incorrect as it describes a degenerative disease affecting mobility, not an acute immune-mediated condition like Guillain-Barr� syndrome. Choice D is incorrect as it describes flu-like symptoms following a flu shot, which is not the same as Guillain-Barr� syndrome.

Correct Answer: A

Rationale: When itraconazole is administered with carbamazepine, itraconazole may increase the serum levels of carbamazepine, potentially leading to toxicity. Therefore, choice A is correct. Discontinuing carbamazepine (choice B) or changing the antiseizure medication (choice C) is not necessary unless advised by a healthcare provider. Choice D, requiring a higher dosage of itraconazole, is not accurate in this scenario.

Correct Answer: C

Rationale: The correct answer is C. Caseous necrosis is characteristic of tuberculosis, where the tissue has a soft, cheese-like appearance. Coagulative necrosis involves protein denaturation, liquefactive necrosis is seen in brain infarcts and abscesses, and autonecrosis is not a recognized term in pathology, making them incorrect choices in this scenario.
