1. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

2. A patient with chronic kidney disease (CKD) is prescribed erythropoietin. What is the primary action of this medication?

• A. Stimulate white blood cell production
• B. Increase platelet count
• C. Promote red blood cell production
• D. Enhance clotting factor production

Correct answer: C

Rationale: Erythropoietin primarily stimulates the bone marrow to produce more red blood cells, which helps to improve oxygen delivery to tissues. In chronic kidney disease, patients often develop anemia due to reduced erythropoietin production by the kidneys. By administering exogenous erythropoietin, the deficient hormone is replaced, leading to an increase in red blood cell production and subsequently improving the oxygen-carrying capacity of the blood.

3. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except

• A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
• B. Reinfection is rare despite adequate treatment
• C. Triple drug therapy has been shown to be more effective than dual drug therapy
• D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy

Correct answer: B

Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.

4. A client reports recent exposure to hepatitis A. What is a common mode of transmission for this virus?

• A. Blood transfusion
• B. Fecal-oral route
• C. Needle sharing
• D. Sexual contact

Correct answer: B

Rationale: Hepatitis A is commonly transmitted through the fecal-oral route, often via ingestion of contaminated food or water. This mode of transmission is why proper hygiene, sanitation, and vaccination are essential in preventing the spread of hepatitis A.

5. Which signs or symptoms are characteristic of an adult client diagnosed with Cushing's syndrome?

• A. Husky voice and complaints of hoarseness.
• B. Warm, soft, moist, salmon-colored skin.
• C. Visible swelling of the neck, with no pain.
• D. Central-type obesity, with thin extremities.

Correct answer: D

Rationale: Cushing's syndrome is characterized by central-type obesity with thin extremities, often referred to as 'truncal obesity.' This pattern of weight distribution is a key feature of Cushing's syndrome due to excessive cortisol levels, leading to fat accumulation in the face, neck, and abdomen, while the extremities remain relatively thin. The other options listed, such as husky voice, hoarseness, warm, soft, moist, salmon-colored skin, and visible swelling of the neck, are not typical findings associated with Cushing's syndrome.
