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. A nurse is providing dietary teaching to a client who has chronic pancreatitis. Which of the following foods should the nurse instruct the client to avoid?

• A. Baked chicken
• B. Grilled salmon
• C. Steamed broccoli
• D. Fried foods

Correct answer: D

Rationale: Clients with chronic pancreatitis should avoid fried foods because they are high in fat, which can exacerbate symptoms and lead to further complications. Baked chicken (choice A), grilled salmon (choice B), and steamed broccoli (choice C) are generally healthier options and can be included in a low-fat diet suitable for individuals with chronic pancreatitis.

3. A nurse is preparing to administer an intermittent enteral feeding to a client who has an NG tube. Which of the following actions should the nurse take?

• A. Heat the feeding to 105°F (40.6°C).
• B. Elevate the head of the bed to 45 degrees.
• C. Flush the tube with 0.9% sodium chloride.
• D. Verify the pH of the gastric aspirate.

Correct answer: D

Rationale: Verifying the pH of the gastric aspirate is the correct action to take before administering an intermittent enteral feeding through an NG tube. This step ensures proper tube placement in the stomach, as the gastric aspirate should have an acidic pH (usually below 5). Heating the feeding solution, elevating the head of the bed, or flushing the tube with saline are not directly related to verifying tube placement and are not the immediate actions needed before administering the feeding.

4. A healthcare professional is preparing to administer an IV fluid bolus of 500 mL over 4 hours to a client who is dehydrated. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 75 mL/hr.
• B. 100 mL/hr.
• C. 125 mL/hr.
• D. 150 mL/hr.

Correct answer: C

Rationale: Setting the IV pump to 125 mL/hr ensures the correct infusion rate for delivering 500 mL over 4 hours. To calculate the mL/hr rate, divide the total volume to be infused (500 mL) by the total time for infusion (4 hours): 500 mL / 4 hours = 125 mL/hr. Choice A (75 mL/hr) is too low and would result in an insufficient infusion rate, potentially delaying fluid resuscitation. Choice B (100 mL/hr) would also be too low and not deliver the fluid within the specified time frame. Choice D (150 mL/hr) is too high and would infuse the fluid too quickly, potentially causing fluid overload and complications.

5. A client has a new prescription for ferrous sulfate. Which of the following instructions should the nurse include in the teaching?

• A. Take this medication on an empty stomach.
• B. Take this medication with milk if it causes stomach upset.
• C. Take this medication with orange juice to increase absorption.
• D. Take an antacid 1 hour after this medication.

Correct answer: C

Rationale: The correct instruction is to take ferrous sulfate with orange juice to increase absorption because the vitamin C content in orange juice enhances iron absorption. Choice A is incorrect because ferrous sulfate should be taken with food to reduce gastrointestinal side effects. Choice B is incorrect because milk can decrease iron absorption. Choice D is incorrect because antacids can reduce the absorption of ferrous sulfate.
