Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client with hypertension is being educated on lifestyle changes by a nurse. Which recommendation is the most important to reduce blood pressure?

• A. Increase water intake
• B. Avoid alcohol consumption
• C. Exercise regularly
• D. Reduce sodium intake

Correct answer: D

Rationale: Reducing sodium intake is crucial in managing hypertension as high sodium levels can lead to fluid retention and increased blood pressure. While increasing water intake is beneficial for overall health, reducing sodium has a more significant impact on blood pressure. Regular exercise is important for cardiovascular health but does not have as direct an impact on blood pressure as sodium reduction. Avoiding alcohol is also important, but in terms of managing blood pressure, reducing sodium intake takes precedence.

3. A postoperative client with a history of diabetes mellitus is showing signs of hyperglycemia. What should the nurse assess first?

• A. Assess for signs of infection.
• B. Monitor the client’s fluid intake and output.
• C. Check the client’s capillary blood glucose level.
• D. Assess the client’s serum potassium level.

Correct answer: C

Rationale: The correct answer is to check the client’s capillary blood glucose level first. In a postoperative client with a history of diabetes mellitus showing signs of hyperglycemia, assessing blood glucose levels is crucial to confirm hyperglycemia and initiate appropriate interventions. While signs of infection are important to assess due to the client's postoperative status and diabetic history, checking the blood glucose level takes precedence to address the immediate concern of hyperglycemia. Monitoring fluid intake and output is essential but not the priority in this scenario. Assessing the client’s serum potassium level is important for overall assessment but not the initial step when hyperglycemia is suspected.

4. A client on long-term corticosteroid therapy for rheumatoid arthritis presents with weakness and hypotension. What is the nurse's first action?

• A. Administer a PRN dose of corticosteroids.
• B. Place the client in a supine position.
• C. Encourage oral fluid intake.
• D. Review the client's recent medication history.

Correct answer: A

Rationale: Administering a PRN dose of corticosteroids is the correct first action when a client on long-term corticosteroid therapy presents with weakness and hypotension. In this scenario, the client is likely experiencing adrenal insufficiency due to prolonged corticosteroid use. Administering corticosteroids promptly can help correct this insufficiency and improve the client's symptoms. Placing the client in a supine position may be necessary for symptomatic hypotension, but addressing the root cause with corticosteroids is more crucial initially. Encouraging oral fluid intake is important for many conditions but is not the priority in this case. Reviewing the client's recent medication history can provide valuable information but is not the first action needed to address the client's current presentation.

5. A client presents to the emergency department with a severe exacerbation of asthma. The nurse notes that the client is using accessory muscles to breathe and has an oxygen saturation of 86%. Which intervention should the nurse implement first?

• A. Place the client in a high-Fowler's position
• B. Obtain a peak flow reading
• C. Administer a bronchodilator
• D. Administer oxygen therapy

Correct answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.
