Nursing Elites

1. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

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

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

2. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?

• A. Encourage the client to eat foods rich in potassium
• B. Administer a potassium-sparing diuretic
• C. Administer a potassium-binding medication
• D. Hold all medications containing potassium

Correct answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.

3. What assessment is most important for the nurse to perform for a client with dehydration receiving IV fluids?

• A. Monitor the client’s electrolyte levels.
• B. Check the client’s urine output hourly.
• C. Assess the client’s skin turgor regularly.
• D. Monitor the client’s blood pressure every 15 minutes.

Correct answer: A

Rationale: The correct answer is to monitor the client’s electrolyte levels. When a client is receiving IV fluids for dehydration, it is crucial to assess their electrolyte levels regularly. Dehydration can lead to imbalances in electrolytes, especially sodium and potassium, which are essential for maintaining fluid balance and proper organ function. Checking urine output (Choice B) is important but not as critical as monitoring electrolyte levels. Assessing skin turgor (Choice C) is an indirect method of assessing dehydration but does not provide specific information about electrolyte imbalances. Monitoring blood pressure (Choice D) is important but not the most critical assessment in this scenario as electrolyte imbalances can have a more direct impact on the client's condition.

4. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

5. A client with chronic obstructive pulmonary disease (COPD) is admitted with increasing shortness of breath. What is the nurse's priority action?

• A. Administer oxygen via nasal cannula.
• B. Reposition the client to improve breathing.
• C. Perform chest physiotherapy.
• D. Encourage the client to cough and deep breathe.

Correct answer: A

Rationale: The correct answer is A: Administer oxygen via nasal cannula. Oxygen therapy is the priority intervention for a client with COPD experiencing increasing shortness of breath. It helps improve oxygenation and relieve respiratory distress. Choice B is not the priority as oxygenation needs to be addressed first. Choice C, chest physiotherapy, may be beneficial but is not the immediate priority in this situation. Choice D, encouraging the client to cough and deep breathe, is not the priority intervention when oxygenation is compromised.
