Nursing Elites

1. A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Serum sodium.
• B. Serum glucose.
• C. Serum potassium.
• D. Serum calcium.

Correct answer: C

Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.

2. Which lab value is critical to monitor in patients receiving warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

3. A nurse is preparing to perform a bladder scan for a client who has overflow incontinence. Which of the following actions should the nurse take?

• A. Place the client in a supine position.
• B. Obtain a prescription for insertion of an indwelling catheter.
• C. Cleanse the client's abdomen with an antiseptic solution.
• D. Prepare the client for urinary catheterization.

Correct answer: D

Rationale: The correct answer is to prepare the client for urinary catheterization. Overflow incontinence may indicate bladder distention, where a bladder scan helps assess the need for catheterization. Placing the client in a supine position (Choice A) is not directly related to the procedure. Obtaining a prescription for an indwelling catheter (Choice B) is not necessary before performing a bladder scan. Cleansing the client's abdomen with an antiseptic solution (Choice C) is not specific to preparing for a bladder scan in this situation.

4. A nurse is reviewing the medical record of a client who has a new prescription for potassium chloride. Which of the following findings should the nurse report to the provider?

• A. Blood pressure 110/70 mm Hg
• B. Heart rate 88/min
• C. Serum potassium 3.2 mEq/L
• D. Sodium 136 mEq/L

Correct answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L is below the normal range, indicating hypokalemia. Before administering potassium chloride, which is used to treat low potassium levels, the nurse should report this finding to the provider for further evaluation and potential adjustment of the treatment plan. Choices A, B, and D are within normal ranges and do not directly relate to the need for potassium chloride administration.

5. A healthcare provider is caring for a client who has been diagnosed with sepsis. Which of the following laboratory results indicates that the client is developing disseminated intravascular coagulation (DIC)?

• A. Elevated hemoglobin
• B. Elevated white blood cell count
• C. Decreased fibrinogen level
• D. Decreased platelet count

Correct answer: D

Rationale: The correct answer is D, decreased platelet count. In disseminated intravascular coagulation (DIC), there is widespread activation of clotting factors leading to the formation of multiple blood clots throughout the body, which can deplete platelets. A decreased platelet count is a hallmark of DIC. Elevated hemoglobin (choice A) and elevated white blood cell count (choice B) are not specific indicators of DIC. While fibrinogen levels (choice C) can be decreased in DIC due to consumption, a decreased platelet count is a more specific and early sign of DIC development.
