Nursing Elites

1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

2. What is the best intervention for a patient with dehydration?

• A. Administer IV fluids
• B. Provide oral fluids
• C. Encourage fluid intake
• D. Administer electrolytes

Correct answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

3. A client who has a new diagnosis of hypertension is being taught about dietary modifications by a nurse. Which of the following instructions should the nurse include?

• A. Limit fluid intake to 2 liters per day.
• B. Increase your intake of whole grains.
• C. Eat 3 large meals daily.
• D. Consume foods high in potassium.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of whole grains.' Whole grains are beneficial for individuals with hypertension as they can help promote heart health. Whole grains are high in fiber, which can help lower blood pressure. Option A is incorrect as fluid intake should be adequate but not restricted to 2 liters per day. Option C is incorrect as it is recommended to have smaller, more frequent meals rather than 3 large meals to help manage hypertension. Option D is incorrect; although foods high in potassium can be beneficial for hypertension, the most appropriate dietary modification to include in this scenario is increasing whole grain intake.

4. A nurse is caring for a client who has chronic obstructive pulmonary disease (COPD) and is experiencing dyspnea. Which of the following actions should the nurse take?

• A. Encourage the client to take deep breaths.
• B. Place the client in a high-Fowler's position.
• C. Administer a bronchodilator.
• D. Administer oxygen at 6 L/min via face mask.

Correct answer: B

Rationale: The correct answer is to place the client in a high-Fowler's position. This position helps improve breathing by expanding the lungs and aiding in better oxygenation. Encouraging the client to take deep breaths may not be effective in managing dyspnea in COPD as it can lead to fatigue. Administering a bronchodilator may be necessary but placing the client in a high-Fowler's position should be the priority. Administering oxygen at 6 L/min via face mask may also be needed, but positioning is the initial intervention to optimize respiratory function.

5. A nurse is providing dietary teaching to a client who is at 8 weeks of gestation and has a body mass index (BMI) of 24. Which of the following instructions should the nurse include?

• A. You should increase your caloric intake by 600 calories per day.
• B. You should increase your caloric intake by 300 calories per day.
• C. You should maintain your prepregnancy caloric intake during the first trimester.
• D. You should increase your caloric intake by 150 calories per day.

Correct answer: B

Rationale: During the first trimester, it is recommended to increase caloric intake by 300 calories per day to support fetal growth and development. Choice A suggesting an increase of 600 calories is excessive and unnecessary. Choice C advising to maintain prepregnancy caloric intake could lead to inadequate nutrition for the developing fetus. Choice D recommending an increase of 150 calories is insufficient to meet the increased energy demands of pregnancy.
