Pathophysiology Practice Questions

1. A patient presents with a sudden onset of severe chest pain radiating to his back. His blood pressure is significantly higher in the right arm than in the left arm. Which of the following conditions is most likely?

Correct answer: C

Rationale: The correct answer is C, aortic dissection. Aortic dissection is characterized by sudden, severe chest pain that can radiate to the back. The discrepancy in blood pressure between the arms (higher in the right arm) is known as a 'pulse deficit' and is a classic finding in aortic dissection. This condition involves a tear in the inner layer of the aorta, leading to the abnormal flow of blood within the aortic wall. Acute myocardial infarction (choice A) presents with chest pain but typically does not cause discrepancies in blood pressure between arms. Pulmonary embolism (choice B) usually presents with chest pain and difficulty breathing but does not cause unequal blood pressures in the arms. Pericarditis (choice D) can cause chest pain exacerbated by breathing or lying down, but it does not typically lead to differences in blood pressure between arms.

2. A male patient with erectile dysfunction has asked for a prescription for sildenafil (Viagra). Before giving this medication, the nurse should assess for which of the following conditions?

Correct answer: B

Rationale: The correct answer is B: Use of nitrates. Sildenafil should not be used by patients taking nitrates due to the risk of severe hypotension. Nitrates can potentiate the hypotensive effects of sildenafil, leading to a significant drop in blood pressure. Assessing for the use of nitrates is crucial to avoid this potentially dangerous interaction. Choices A, C, and D are incorrect because they are not specifically contraindications for the use of sildenafil. While a history of hypertension should be considered, it is not as critical as the use of nitrates when prescribing sildenafil.

3. A 70-year-old man has enjoyed good overall health for all of his adult life, but he has been experiencing urinary frequency and dribbling that has culminated in a diagnosis of benign prostatic hypertrophy (BPH). As a result, the patient has been prescribed finasteride (Proscar). When teaching the patient about the potential adverse effects of the drug, the nurse should ensure that he knows about the possibility of

Correct answer: A

Rationale: The correct potential adverse effect of finasteride (Proscar) that the nurse should educate the patient about is sexual dysfunction. Finasteride is known to cause sexual side effects such as decreased libido, erectile dysfunction, and ejaculation disorders. Urethral burning, kidney stones, and visual disturbances are not commonly associated with finasteride use, making them incorrect choices for this scenario.

4. A nurse recalls an example of an immune-complex-mediated disease is:

Correct answer: C

Rationale: The correct answer is C: Serum sickness. Serum sickness is characterized by the formation of immune complexes in response to certain medications or proteins. These immune complexes can deposit in tissues, leading to inflammation and tissue damage. Bronchial asthma (Choice A) is a chronic inflammatory condition of the airways not primarily mediated by immune complexes. Contact dermatitis (Choice B) is a type IV hypersensitivity reaction mediated by T cells, not immune complexes. Rheumatoid arthritis (Choice D) is an autoimmune disease where antibodies target self-antigens, but it is not primarily mediated by immune complexes.

5. A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse discuss with the patient regarding the risks of HRT?

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is indeed associated with an increased risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because although HRT may decrease the risk of osteoporosis, the focus of concern in this case is the increased risk of venous thromboembolism. Choice C is incorrect as it mentions the risk of breast cancer, which is not the primary concern when discussing HRT with a patient with a history of venous thromboembolism. Choice D is also incorrect as it mentions cardiovascular events, which are not the main focus of risk associated with HRT in this scenario.
