Nursing Elites

1. In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?

• A. Decreased urine specific gravity.
• B. Elevated urine glucose.
• C. Decreased serum potassium.
• D. Increased serum sodium.

Correct answer: A

Rationale: Diabetes insipidus is characterized by the kidneys' inability to concentrate urine, leading to decreased urine specific gravity. This results in the excretion of large volumes of dilute urine, causing a decrease in urine specific gravity. Therefore, when evaluating a suspected case of diabetes insipidus, a finding of decreased urine specific gravity is indicative of this condition.

2. A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: Patients prescribed methotrexate should be advised to take folic acid supplements as prescribed. Methotrexate can deplete folic acid levels, leading to side effects. By taking folic acid supplements as directed, the patient can reduce the risk of experiencing adverse effects associated with methotrexate therapy. It is important to note that the effects of methotrexate may not be immediate, so realistic expectations should be set with the patient. Alcohol should be avoided while taking methotrexate due to potential interactions and increased risk of liver toxicity. There is no specific recommendation to limit fluid intake to 1 liter per day in relation to methotrexate therapy.

3. A patient with coronary artery disease (CAD) is prescribed a statin medication. What should the nurse include in the patient education?

• A. Take the medication with food.
• B. Report any muscle pain or weakness.
• C. Increase intake of grapefruit juice.
• D. Avoid foods high in potassium.

Correct answer: B

Rationale: Patients prescribed statin medications should be educated to report any muscle pain or weakness to their healthcare provider promptly. Muscle pain or weakness could be a sign of rhabdomyolysis, a serious side effect associated with statin use that requires medical attention. Choices A, C, and D are incorrect. Taking statins with food or increasing grapefruit juice intake are not necessary recommendations. Avoiding foods high in potassium is also not directly related to statin use.

4. A 35-year-old man presents with difficulty swallowing, weight loss, and regurgitation of undigested food. A barium swallow shows a 'bird beak' appearance of the lower esophagus. What is the most likely diagnosis?

• A. Esophageal cancer
• B. Achalasia
• C. Peptic stricture
• D. Gastroesophageal reflux disease

Correct answer: B

Rationale: The 'bird beak' appearance on a barium swallow is characteristic of achalasia, a condition where the lower esophageal sphincter fails to relax properly. This leads to difficulty swallowing, weight loss, and regurgitation of undigested food, which are hallmark symptoms of achalasia.

5. 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.
