Nursing Elites

1. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

2. What is the most likely diagnosis in a 30-year-old woman with right upper quadrant pain, fever, and jaundice, along with elevated white blood cell count and bilirubin levels?

• A. Acute hepatitis
• B. Acute cholecystitis
• C. Acute cholangitis
• D. Pancreatic cancer

Correct answer: C

Rationale: The combination of right upper quadrant pain, fever, jaundice, elevated white blood cell count, and bilirubin levels is classic for acute cholangitis, which is an infection of the bile ducts. Acute hepatitis typically presents with other liver function abnormalities, while acute cholecystitis is characterized by gallbladder inflammation. Pancreatic cancer would not typically present with these specific symptoms and lab findings.

3. A client with hyperthyroidism is prescribed propylthiouracil (PTU). Which instruction should the nurse include in the client's discharge teaching?

• A. Report any signs of infection, such as sore throat or fever, to your healthcare provider.'
• B. Increase your intake of iodine-rich foods, such as seafood and dairy products.'
• C. Take the medication on an empty stomach for better absorption.'
• D. You may experience weight gain and fatigue as side effects of the medication.'

Correct answer: A

Rationale: Propylthiouracil (PTU) can suppress bone marrow function, increasing the risk of infection, so it is important to report signs of infection promptly.

4. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

5. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?

• A. Wilson's disease
• B. Hemochromatosis
• C. Alpha-1 antitrypsin deficiency
• D. Autoimmune hepatitis

Correct answer: B

Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.
