Nursing Elites

1. 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.

2. A 32-year-old woman presents with a 10-month history of an intermittent burning sensation in the epigastrium that is sometimes related to eating. She has heard about bacteria that can cause gastrointestinal (GI) symptoms. She has had no change in her weight and denies dysphagia. Her laboratory tests are normal. Which of the following would you recommend?

• A. Serum qualitative test for H. pylori
• B. Refer for endoscopy
• C. Obtain an upper GI series
• D. Treat her for H. pylori infection

Correct answer: A

Rationale: The patient presents with dyspepsia, described as an intermittent burning sensation in the epigastrium, sometimes related to eating. In individuals under 45 years without warning signs such as anemia, weight loss, or dysphagia, a serum qualitative test for H. pylori is recommended to document H. pylori infection, especially if the patient has not been previously treated. It's important to note that a serum IgG can remain positive post-eradication. If H. pylori-positive patients do not respond to treatment, an endoscopy would be the next step for evaluation. An upper GI series is less sensitive than endoscopy in detecting lesions of the upper GI tract and cannot specifically detect H. pylori. Empiric therapy for H. pylori without confirmation is not recommended.

3. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?

• A. Administer the prescribed PRN lorazepam (Ativan).
• B. Start the prescribed PRN oxygen at 2 to 4 L/min.
• C. Administer the prescribed normal saline bolus and insulin.
• D. Encourage the patient to practice guided imagery for relaxation.

Correct answer: C

Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.

4. Why is a low-protein diet recommended for a client with hepatic encephalopathy?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Increased ammonia levels
• D. Electrolyte imbalance

Correct answer: C

Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.

5. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.
