Nursing Elites

1. A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?

• A. Decrease blood glucose levels
• B. Reduce serum ammonia levels
• C. Increase platelet count
• D. Lower serum bilirubin levels

Correct answer: B

Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

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 providing discharge teaching for a client with heart failure. Which instruction should be included to prevent fluid overload?

• A. Weigh yourself daily and report a gain of 2 pounds in 24 hours
• B. Increase fluid intake to stay hydrated
• C. Consume a high-sodium diet to retain fluids
• D. Engage in vigorous exercise daily

Correct answer: A

Rationale: The correct answer is A: 'Weigh yourself daily and report a gain of 2 pounds in 24 hours.' Daily weight monitoring is crucial for detecting fluid retention early in clients with heart failure. Reporting a gain of 2 pounds in 24 hours can indicate fluid overload, prompting timely intervention. Choice B is incorrect because increasing fluid intake can exacerbate fluid overload in clients with heart failure. Choice C is incorrect as a high-sodium diet can worsen fluid retention. Choice D is incorrect as vigorous exercise can strain the heart and worsen heart failure symptoms.

4. The nurse uses a diagram to show that the tetralogy of Fallot involves a combination of four congenital defects. What are the defects?

• A. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy
• B. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
• C. Aortic stenosis, atrial septal defect, overriding aorta, right ventricular hypertrophy
• D. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy

Correct answer: B

Rationale: The correct answer is B: Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. Tetralogy of Fallot involves these four congenital defects. Choice A is incorrect because it includes aortic stenosis instead of pulmonary stenosis, atrial septal defect instead of ventricular septal defect, and left ventricular hypertrophy instead of right ventricular hypertrophy. Choice C is incorrect as it includes aortic stenosis and atrial septal defect instead of pulmonary stenosis and ventricular septal defect. Choice D is incorrect because it includes aortic hypertrophy instead of overriding aorta.

5. The nurse is reviewing blood pressure readings for a group of clients on a medical unit. Which client is at the highest risk for complications related to hypertension?

• A. Post-menopausal Caucasian female who overeats and is 20% above her ideal body weight.
• B. Young adult Hispanic female who has hemoglobin at 11 g/dl (110 g/L) and drinks beer daily.
• C. Older adult who consumes a diet of smoked, cured, and pickled foods.
• D. Middle-aged African-American male who has a serum creatinine level of 2.9 mg/dL (256.4 micromol/L).

Correct answer: D

Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.
