Nursing Elites

1. A healthcare provider is assessing a client who is receiving heparin therapy for deep vein thrombosis (DVT). Which of the following laboratory values should the provider monitor to evaluate the therapeutic effect of the heparin?

• A. Platelet count
• B. Partial thromboplastin time (PTT)
• C. Prothrombin time (PT)
• D. Bleeding time

Correct answer: B

Rationale: The Partial Thromboplastin Time (PTT) is the correct laboratory value to monitor heparin therapy. PTT measures the time it takes for blood to clot and is specifically used to evaluate the effectiveness of anticoagulation therapy such as heparin. Monitoring the PTT helps ensure that the heparin dose is within the therapeutic range. Platelet count, Prothrombin time (PT), and Bleeding time are not specific laboratory values for monitoring the therapeutic effect of heparin therapy. Platelet count is more indicative of platelet function, PT is used to monitor warfarin therapy, and Bleeding time assesses platelet function rather than the effect of heparin therapy.

2. A client has been prescribed ferrous sulfate. Which instruction should the nurse include?

• A. Take with meals
• B. Take with a glass of orange juice
• C. Take at bedtime
• D. Take with milk

Correct answer: B

Rationale: The correct instruction for a client prescribed ferrous sulfate is to take it with a glass of orange juice. Vitamin C, found in orange juice, enhances the absorption of iron, making it more effective. Taking ferrous sulfate with meals, at bedtime, or with milk can decrease its absorption and effectiveness, so these options are incorrect.

3. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

4. A healthcare professional is assessing a client for signs of anemia. Which of the following findings should the healthcare professional expect?

• A. Increased energy levels
• B. Pale skin
• C. Elevated blood pressure
• D. Decreased heart rate

Correct answer: B

Rationale: Pale skin is a common sign of anemia due to reduced hemoglobin levels, leading to decreased oxygen delivery to tissues. This results in skin pallor. Choices A, C, and D are incorrect. Anemia typically causes fatigue and decreased energy levels (not increased), low blood pressure (not elevated), and tachycardia (increased heart rate) to compensate for the decreased oxygen-carrying capacity of the blood.

5. When educating a patient on the use of levodopa-carbidopa, which information should the nurse include?

• A. It is a cure for Parkinson's disease
• B. Monitor for dyskinesia
• C. It can be taken at any time
• D. It has no side effects

Correct answer: B

Rationale: The correct answer is B: 'Monitor for dyskinesia.' Levodopa-carbidopa can cause dyskinesia as a side effect, which is characterized by involuntary muscle movements. Patients need to be monitored for this adverse effect and instructed to report it to their healthcare provider. Choices A, C, and D are incorrect because levodopa-carbidopa is not a cure for Parkinson's disease, it should be taken at specific times for optimal effect, and it does have side effects, such as dyskinesia.
