Nursing Elites

1. What most influences the severity of respiratory distress syndrome (RDS)?

• A. Poor cough and gag reflex
• B. The gestational age at birth
• C. Administering high concentrations of oxygen
• D. The sex of the infant

Correct answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.

2. A healthcare worker with no known exposure to tuberculosis has received a Mantoux tuberculosis skin test. The nurse's assessment of the test after 62 hours indicates 5mm of erythema without induration. Which is the best initial nursing action?

• A. Review the healthcare worker's history for possible exposure to TB.
• B. Instruct the healthcare worker to return for a repeat test in 1 week.
• C. Refer the healthcare worker to a healthcare provider for isoniazid (INH) therapy.
• D. Document negative results in the healthcare worker's medical record.

Correct answer: D

Rationale: A Mantoux tuberculosis skin test without induration is considered negative. In this case, with 5mm of erythema and no induration, the result is negative, indicating no current infection. The best initial nursing action is to document these negative results in the healthcare worker's medical record. Reviewing the history for possible exposure to TB is unnecessary as the test result is negative. Instructing the healthcare worker to return for a repeat test or referring for INH therapy is not warranted when the test is negative.

3. The nurse is caring for a client with myasthenia gravis. Which symptom is most important for the nurse to report to the healthcare provider?

• A. Diplopia (double vision)
• B. Difficulty swallowing
• C. Weakness in the legs
• D. Fatigue

Correct answer: B

Rationale: In a client with myasthenia gravis, difficulty swallowing is the most crucial symptom to report to the healthcare provider. This is because it can lead to aspiration, a severe complication in these clients. Diplopia (double vision) and weakness in the legs are common symptoms of myasthenia gravis but are not as immediately dangerous as difficulty swallowing. Fatigue is also a common symptom in myasthenia gravis but does not pose the same risk of aspiration as difficulty swallowing.

4. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

5. The nurse is teaching a client with glomerulonephritis about self-care. Which dietary recommendations should the nurse encourage the client to follow?

• A. Increase intake of high-fiber foods, such as bran cereal
• B. Restrict protein intake by limiting meats and other high-protein foods.
• C. Limit oral fluid intake to 500ml per day
• D. Increase intake of potassium-rich foods such as bananas and cantaloupe.

Correct answer: B

Rationale: The correct answer is B: Restrict protein intake by limiting meats and other high-protein foods. In glomerulonephritis, reducing protein intake helps to lower the workload on the kidneys, as excessive protein can lead to increased production of waste products that the kidneys must filter. This restriction can help prevent further damage to the kidneys. Choices A, C, and D are incorrect because: A) Increasing high-fiber foods like bran cereal is beneficial for other conditions but not specific to glomerulonephritis. C) Limiting oral fluid intake to 500ml per day is not appropriate as fluid restrictions are usually individualized based on the client's condition and kidney function. D) Increasing potassium-rich foods like bananas and cantaloupe may not be suitable for all clients with glomerulonephritis, as potassium levels can be affected in kidney disease and individual needs may vary.
