ATI Pathophysiology Exam 2

1. What causes atherosclerotic plaques to form initially?

Correct answer: B

Rationale: Atherosclerotic plaques form initially due to injury to the coronary artery endothelium, which triggers a cascade of events leading to plaque buildup. Choice A is incorrect because atherosclerotic plaques do not form due to an interruption of blood flow to the brain. Choice C is incorrect as statin medications are actually used to help lower cholesterol and reduce the risk of plaque formation. Choice D is incorrect as poor dietary modifications can contribute to atherosclerosis but are not the initial cause of plaque formation.

2. What type of immunity will the hepatitis B series provide a nursing student scheduled to receive it?

Correct answer: A

Rationale: The correct answer is active immunity. The hepatitis B series immunization will provide active immunity, where the individual's immune system is stimulated to produce antibodies against the hepatitis B virus. This type of immunity is long-lasting and provides protection against future exposures. Passive immunity (choice B) involves the transfer of pre-formed antibodies and is temporary. Innate immunity (choice C) is the body's natural defense mechanisms, present at birth. Natural immunity (choice D) refers to immunity acquired through normal life processes, such as recovering from an infection.

3. When starting on oral contraceptives, what should the nurse emphasize about the potential interactions with other medications?

Correct answer: A

Rationale: The correct answer is A. Oral contraceptives can be less effective when taken with certain antibiotics, so patients should be informed about the potential need for additional contraception. Choice B is incorrect because taking oral contraceptives with food does not affect their effectiveness. Choice C is incorrect because oral contraceptives may take some time to become fully effective. Choice D is incorrect because oral contraceptives can interact with other medications, especially certain antibiotics, affecting their efficacy.

4. A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse be most concerned about?

Correct answer: C

Rationale: The correct answer is C: Increased risk of cardiovascular events. Cardiovascular events such as stroke and myocardial infarction are the most concerning adverse effects of testosterone therapy, especially in older patients. Choice A, increased risk of breast cancer, is not a common adverse effect of testosterone therapy in males. Choice B, increased risk of liver dysfunction, is a potential adverse effect but is not the most concerning. Choice D, increased risk of prostate cancer, is a consideration in patients with a history of prostate cancer or those with prostate carcinoma, not typically in patients receiving testosterone therapy for hypogonadism.

5. The unique clinical presentation of a 3-month-old infant in the emergency department leads the care team to suspect botulism. Which assessment question posed to the parents is likely to be most useful in the differential diagnosis?

Correct answer: B

Rationale: The correct answer is B. Poor feeding and constipation are common early symptoms of infant botulism, which is caused by a neurotoxin that impairs muscle function. Option A is unrelated to the presentation of botulism. Option C does not directly relate to the symptoms of botulism. Option D is more indicative of respiratory issues rather than the constellation of symptoms seen in botulism.
