Nursing Elites

1. A nurse is preparing to teach a client about the use of a peak flow meter. Which of the following instructions should the nurse include?

• A. Place the mouthpiece in your mouth and blow out as quickly as you can.
• B. Exhale slowly into the mouthpiece over 5 seconds.
• C. Take a slow deep breath before blowing into the mouthpiece.
• D. Blow into the mouthpiece at a steady rate for 3 seconds.

Correct answer: A

Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

2. A nurse is caring for a client who has a wound infection and is receiving gentamicin. Which of the following laboratory values should the nurse monitor to detect an adverse effect of this medication?

• A. Creatinine.
• B. Aspartate aminotransferase (AST).
• C. White blood cell count.
• D. Serum glucose.

Correct answer: A

Rationale: The correct answer is A: Creatinine. Gentamicin can cause nephrotoxicity, leading to impaired kidney function. Monitoring creatinine levels helps the nurse detect any potential kidney damage. Choice B, Aspartate aminotransferase (AST), is not typically affected by gentamicin. Choice C, White blood cell count, is not directly related to gentamicin adverse effects. Choice D, Serum glucose, is not specifically monitored for gentamicin adverse effects.

3. A nurse is caring for a client who has chronic kidney disease and is experiencing fluid volume overload. Which of the following findings should the nurse expect?

• A. Decreased blood pressure
• B. Increased urine output
• C. Decreased heart rate
• D. Increased heart rate

Correct answer: A

Rationale: In a client with chronic kidney disease experiencing fluid volume overload, the nurse should expect a decreased blood pressure. Fluid volume overload can lead to poor cardiac output, which in turn can cause a decrease in blood pressure. Choices B, C, and D are incorrect. Increased urine output is not expected in fluid volume overload; decreased heart rate is not typically associated with fluid volume overload; and an increased heart rate is more commonly seen in response to fluid overload to compensate for the decreased cardiac output.

4. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Hemoglobin
• B. Platelet count
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

5. A client has a nasogastric tube and is receiving intermittent enteral feedings. Which of the following actions should the nurse take to prevent aspiration?

• A. Administer a bolus feeding over 10 minutes.
• B. Elevate the head of the bed to 45 degrees during feedings.
• C. Flush the tube with 10 mL of sterile water before feedings.
• D. Position the client on the left side during feedings.

Correct answer: B

Rationale: To prevent aspiration in clients with a nasogastric tube receiving intermittent enteral feedings, the nurse should elevate the head of the bed to 45 degrees during feedings. This position helps reduce the risk of regurgitation and aspiration of the feeding contents. Administering a bolus feeding over 10 minutes (choice A) may not prevent aspiration as effectively as elevating the head of the bed. Flushing the tube with sterile water before feedings (choice C) is important for tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (choice D) is not the recommended action to prevent aspiration; elevating the head of the bed is more effective.
