Nursing Elites

1. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

2. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

3. A client with tuberculosis is prescribed rifampin. What side effect should the nurse inform the client about?

• A. Report orange-colored urine as a sign of kidney dysfunction.
• B. Expect red-orange discoloration of urine as a harmless side effect.
• C. Monitor for signs of liver toxicity.
• D. Call the healthcare provider if vision changes occur.

Correct answer: B

Rationale: The correct answer is B. Rifampin can cause red-orange discoloration of bodily fluids, including urine, saliva, and tears. This is a harmless side effect, but clients should be informed beforehand to prevent alarm. Choice A is incorrect as orange-colored urine is not a sign of kidney dysfunction related to rifampin. Choice C is incorrect because rifampin is more commonly associated with liver toxicity rather than kidney dysfunction. Choice D is incorrect as vision changes are not a typical side effect of rifampin.

4. A client with diabetes mellitus is scheduled for surgery, and their blood glucose level is 280 mg/dL. What is the nurse's priority action?

• A. Administer insulin as prescribed.
• B. Delay surgery until the blood glucose is below 180 mg/dL.
• C. Check the client’s hemoglobin A1C level.
• D. Administer IV fluids to flush excess glucose.

Correct answer: A

Rationale: The correct answer is A: Administer insulin as prescribed. In clients with diabetes, high blood glucose levels can increase the risk of infection and impair healing after surgery. Administering insulin as prescribed helps reduce blood glucose to a safer level before surgery, preventing complications. Choice B is incorrect because delaying surgery without addressing the high blood glucose level does not address the immediate issue. Choice C is incorrect as checking the client's hemoglobin A1C level is not the priority when dealing with acute high blood glucose levels before surgery. Choice D is incorrect as administering IV fluids may help with hydration but does not directly address the high blood glucose level that needs immediate attention.

5. A client with asthma is experiencing wheezing. What is the nurse’s priority intervention?

• A. Administer a bronchodilator immediately.
• B. Increase the client's oxygen flow rate.
• C. Perform a chest x-ray to assess lung function.
• D. Place the client in a high Fowler’s position.

Correct answer: A

Rationale: The correct answer is A: Administer a bronchodilator immediately. Wheezing in a client with asthma indicates bronchoconstriction, which can compromise airflow. Administering a bronchodilator is the priority intervention as it helps to open the airways, relieve bronchoconstriction, and improve breathing. Increasing the oxygen flow rate (choice B) may be necessary but is not the priority when the airways are constricted. Performing a chest x-ray (choice C) is not the immediate action needed in this situation. Placing the client in a high Fowler's position (choice D) may provide some relief, but administering a bronchodilator to address the bronchoconstriction is the priority intervention.
