Nursing Elites

1. A client is newly prescribed lithium for bipolar disorder. Which finding is most important to report to the healthcare provider?

• A. A serum lithium level of 1.2 mEq/L.
• B. Fine hand tremors noted after starting the medication.
• C. A blood pressure of 110/60 mmHg.
• D. A serum sodium level of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. Fine hand tremors noted after starting lithium are an early sign of lithium toxicity. It is crucial to report this finding to the healthcare provider promptly. Adjusting the dose or monitoring serum levels more closely may be necessary to prevent further toxicity. Choice A, a serum lithium level of 1.2 mEq/L, is within the therapeutic range (0.6-1.2 mEq/L) for treating bipolar disorder. Choice C, a blood pressure of 110/60 mmHg, and Choice D, a serum sodium level of 140 mEq/L, are within normal limits and not directly related to lithium therapy or toxicity.

2. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

3. The client with infective endocarditis must be assessed frequently by the home health nurse. Which finding suggests that antibiotic therapy is not effective and must be reported by the nurse immediately to the healthcare provider?

• A. Nausea and vomiting
• B. Fever of 103 degrees Fahrenheit (39.5 degrees Celsius)
• C. Diffuse macular rash
• D. Muscle tenderness

Correct answer: B

Rationale: A fever of 103 degrees Fahrenheit indicates that the infection is not under control despite antibiotic therapy. Fever is a common sign of ongoing infection or inadequate response to treatment. Nausea and vomiting, diffuse macular rash, and muscle tenderness are not typically indicative of the effectiveness of antibiotic therapy in treating infective endocarditis.

4. Before a client with renal failure undergoes hemodialysis, what should the nurse assess?

• A. Check the client's potassium levels
• B. Review the client's medication list
• C. Assess the client's peripheral pulses
• D. Monitor the client's urine output

Correct answer: A

Rationale: The correct answer is to check the client's potassium levels. Potassium levels are crucial to assess before hemodialysis in a client with renal failure because hyperkalemia (high potassium) is a common complication in these patients. Hemodialysis aims to remove excess potassium from the blood, making it essential to monitor potassium levels to determine the need for appropriate interventions. Reviewing the client's medication list (Choice B) is important for overall care but is not as directly relevant to the immediate concerns before hemodialysis. Assessing peripheral pulses (Choice C) and monitoring urine output (Choice D) are important aspects of nursing assessment but are not as directly related to the specific preparation needed before hemodialysis in a client with renal failure.

5. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.
