ATI Pathophysiology Final Exam

1. A 50-year-old female was diagnosed with sideroblastic anemia. Which of the following assessment findings would most likely occur?

A. Bronze-colored skin
B. Decreased iron
C. Normochromic erythrocytes
D. Aplastic bone marrow

Correct answer: A

Rationale: The correct answer is A: 'Bronze-colored skin.' Sideroblastic anemia is characterized by excess iron deposition, leading to bronze-colored skin. This occurs due to the abnormal accumulation of iron in tissues. Choices B, C, and D are incorrect because sideroblastic anemia does not typically present with decreased iron levels, normochromic erythrocytes, or aplastic bone marrow.

2. A patient is starting on finasteride (Proscar) for the treatment of benign prostatic hyperplasia (BPH). What should the nurse include in the patient teaching?

A. The medication will cure BPH after treatment is complete.
B. The effects of the medication may take several weeks or months to become noticeable.
C. The medication may cause increased hair growth.
D. The medication may decrease libido.

Correct answer: B

Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable. It is important for the nurse to educate the patient about this expected time frame to manage expectations. Choice A is incorrect because finasteride does not cure BPH but helps in managing symptoms. Choice C is incorrect as one of the side effects of finasteride is decreased hair growth. Choice D is incorrect as finasteride may cause a decrease in libido as a side effect.

3. What function does aldosterone serve in the body?

A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
D. Aldosterone enhances intracellular sodium production and lowers blood pressure

Correct answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.

4. In a 70-year-old man with a history of chronic obstructive pulmonary disease (COPD) reporting increasing shortness of breath, wheezing, and cough, which finding would indicate a potential exacerbation of his COPD?

A. Increased wheezing
B. Decreased respiratory rate
C. Improved exercise tolerance
D. Decreased sputum production

Correct answer: A

Rationale: The correct answer is A: Increased wheezing. In COPD exacerbations, there is a worsening of symptoms such as increased wheezing due to airway inflammation and narrowing. Choices B, C, and D are incorrect. Decreased respiratory rate would not be expected in COPD exacerbation as it is usually a compensatory mechanism to maintain oxygenation. Improved exercise tolerance is not a typical finding in exacerbations but rather a sign of improvement. Decreased sputum production is also not indicative of exacerbation, as exacerbations are often associated with increased sputum production.

5. In which of the following cases is dehydration more likely to occur?

A. A 50-year-old woman who is a bodybuilder
B. A 50-year-old man who is morbidly obese
C. A 10-year-old child who is thin
D. A 30-year-old with multiple sclerosis

Correct answer: B

Rationale: Dehydration is more likely to occur in a 50-year-old man who is morbidly obese due to the increased risk of conditions like diabetes and heart disease that can lead to fluid imbalances. Being morbidly obese can also strain the body's systems, increasing the need for water. The other choices are less likely to experience dehydration as a primary concern. While being a bodybuilder may require strict hydration practices, dehydration is more prevalent in individuals with conditions like obesity.
