Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. A client with bipolar disorder is prescribed lithium. What should the nurse teach the client about lithium toxicity?

• A. Take the medication with meals to prevent gastrointestinal upset.
• B. Report any symptoms of nausea, vomiting, or diarrhea.
• C. Monitor lithium levels regularly and maintain hydration.
• D. Avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) while on lithium.

Correct answer: D

Rationale: The correct answer is D. Clients taking lithium should avoid NSAIDs as they can increase lithium levels leading to toxicity. It is essential to monitor lithium levels regularly and maintain hydration to prevent toxicity. Reporting symptoms like nausea, vomiting, or diarrhea is important, but the key teaching point regarding lithium toxicity is to avoid NSAIDs.

3. The nurse is caring for a client with a history of congestive heart failure (CHF) who is receiving digoxin therapy. The client reports seeing halos around lights. Which action should the nurse take?

• A. Assess the client's digoxin level
• B. Increase the client's fluid intake
• C. Check the client's blood pressure
• D. Administer a dose of potassium

Correct answer: A

Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity. The nurse should assess the client's digoxin level to determine if the dose needs to be adjusted or if the medication should be held. Increasing fluid intake or checking blood pressure would not directly address the symptom of halos around lights. Administering a dose of potassium is not indicated without knowing the digoxin level and could potentially worsen the toxicity.

4. While auscultating heart sounds, the nurse hears a swishing sound. How should this sound be documented?

• A. Heart murmur.
• B. Murmur.
• C. S3 sound.
• D. S4 sound.

Correct answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

5. The healthcare provider is assessing a client who has just received anesthesia. What is the most critical finding to report to the healthcare provider?

• A. Client reports dizziness
• B. Client has a drop in blood pressure
• C. Client experiences mild nausea
• D. Client reports dry mouth

Correct answer: B

Rationale: A significant drop in blood pressure following anesthesia could indicate a serious reaction, such as hypovolemia or anesthetic-induced hypotension. This requires immediate medical attention, while other symptoms like dizziness, mild nausea, and dry mouth are more common and less critical. Dizziness could be expected due to the effects of anesthesia, mild nausea is a common side effect, and dry mouth is a known effect of anesthesia as well.
