ATI Pathophysiology Quizlet

1. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

Correct answer: B

Rationale: The correct answer is B: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates combined with sildenafil can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of peptic ulcer disease, use of antihypertensive medications, or a history of hypertension are not direct contraindications for sildenafil use.

2. A man with gout has developed large, hard nodules around his toes and elbows. The phase of gout he is in is:

Correct answer: D

Rationale: The correct answer is 'chronic gout.' Chronic gout is characterized by the presence of tophi, which are large, hard nodules that can develop around joints like toes and elbows. These tophi are a sign of longstanding, untreated gout. Choice A, 'asymptomatic,' is incorrect as the presence of tophi indicates a symptomatic phase. Choice B, 'acute flare,' is incorrect as acute flares are characterized by sudden and severe pain, inflammation, and redness in the joints, not the development of tophi. Choice C, 'the intercritical period,' is also incorrect as this phase occurs between acute attacks and is typically asymptomatic, without the presence of tophi.

3. A 30-year-old female has suffered a third-degree burn to her hand after spilling hot oil in a kitchen accident. Which teaching point by a member of her care team is most appropriate?

Correct answer: D

Rationale: In third-degree burns, infection is a major concern due to the extensive damage to the skin. Monitoring for infection is crucial. Choice A is incorrect because third-degree burns often require skin grafts due to the severity of the injury. Choice B is incorrect as loss of sensation is more common in nerve damage and not necessarily in burns. Choice C is incorrect because while elevation can help with swelling in minor burns, it is not the most critical concern in third-degree burns.

4. Which of the following is a clinical manifestation of hyperthyroidism?

Correct answer: A

Rationale: The correct answer is A: Tachycardia. Tachycardia, which is an increased heart rate, is a classic clinical manifestation of hyperthyroidism. In hyperthyroidism, there is an excess production of thyroid hormones, leading to an increased metabolic rate. This increased metabolism can cause symptoms such as a rapid heart rate. Choices B, C, and D are incorrect because constipation, weight gain, and fatigue are more commonly associated with hypothyroidism, where there is a deficiency of thyroid hormones leading to a slower metabolic rate.

5. A patient has been prescribed mifepristone (RU-486) to terminate a pregnancy. How does this drug achieve its therapeutic effect?

Correct answer: A

Rationale: Mifepristone (RU-486) functions by inhibiting the action of progesterone, a hormone crucial for maintaining pregnancy. By blocking progesterone, mifepristone disrupts the uterine environment necessary for pregnancy continuation, ultimately leading to termination. Choice B is incorrect because mifepristone does not increase estrogen levels; instead, it acts on progesterone. Choice C is incorrect as mifepristone's mechanism does not involve altering the uterine lining to prevent implantation. Choice D is incorrect because mifepristone does not directly stimulate uterine contractions; its primary action is through progesterone inhibition.
