Nursing Elites

1. A healthcare professional is preparing to administer a flu vaccine. Which of the following should the healthcare professional verify?

• A. Client's age
• B. Client's allergy to eggs
• C. Client's vaccination history
• D. Client's weight

Correct answer: C

Rationale: The healthcare professional should verify the client's vaccination history to ensure they are due for the flu vaccine. Verifying the client's age (choice A) is important for other vaccines but not specifically for the flu vaccine. While allergy to eggs (choice B) is relevant as the flu vaccine is traditionally produced in eggs, it is not the top priority for verification. The client's weight (choice D) is not directly related to the administration of the flu vaccine.

2. A healthcare professional is preparing to administer a dose of hydrocodone. Which of the following should the healthcare professional assess first?

• A. Respiratory rate
• B. Blood pressure
• C. Pain level
• D. Heart rate

Correct answer: A

Rationale: When administering hydrocodone, a healthcare professional should assess the respiratory rate first because hydrocodone is an opioid that can lead to respiratory depression. Monitoring the respiratory rate helps to detect any signs of respiratory distress or depression early on. Assessing blood pressure, pain level, or heart rate is also important but not the priority when administering hydrocodone, as the risk of respiratory depression is a more critical concern.

3. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

4. A nurse is providing discharge teaching to a client with heart failure and a prescription for furosemide 20 mg PO twice daily. Which of the following instructions should the nurse include in the teaching?

• A. Monitor for increased blood pressure
• B. Increase intake of high-potassium foods
• C. Expect an increase in swelling in the hands and feet
• D. Take the second dose at bedtime

Correct answer: B

Rationale: The correct answer is B: "Increase intake of high-potassium foods." Furosemide is a loop diuretic that can lead to hypokalemia, a condition characterized by low potassium levels. To prevent this adverse effect, the client should increase their intake of high-potassium foods. Choice A is incorrect because furosemide typically leads to decreased blood pressure, not increased. Choice C is incorrect because furosemide is used to reduce swelling, not increase it. Choice D is incorrect because the second dose of furosemide should be taken in the morning to prevent nocturia.

5. A client has been diagnosed with tuberculosis. Which of the following precautions should the nurse initiate to prevent transmission of the disease?

• A. Contact precautions
• B. Airborne precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: B

Rationale: Tuberculosis is spread through small droplets, measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client with TB under airborne precautions to prevent the transmission of the disease. Choice A, contact precautions, are used for diseases that spread by direct or indirect contact. Choice C, droplet precautions, are for diseases transmitted by large droplets. Choice D, protective environment, is used for clients who have compromised immune systems.
