Nursing Elites

1. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.

2. Which intervention should the nurse implement to enhance the efficacy of the client's asthma medication therapy?

• A. Administer the albuterol inhaler before other inhaled medications.
• B. Provide oxygen via nasal cannula at 2 liters/minute.
• C. Encourage the client to drink three liters of fluids daily.
• D. Keep the client upright during nebulizer therapy.

Correct answer: A

Rationale: Administering a bronchodilator such as albuterol as the first step is crucial to open the airways, allowing better penetration of subsequent inhaled medications and enhancing their overall efficacy in managing asthma symptoms.

3. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

4. The client has acute kidney injury (AKI). Which assessment finding requires immediate intervention?

• A. Urine output of 50 ml in the last hour.
• B. Serum potassium of 6.2 mEq/L.
• C. Blood pressure of 150/90 mm Hg.
• D. Serum creatinine of 2.5 mg/dL.

Correct answer: B

Rationale: An elevated serum potassium level of 6.2 mEq/L in a client with AKI can lead to life-threatening cardiac arrhythmias, necessitating immediate intervention. Hyperkalemia is a serious complication in AKI as impaired kidney function can result in the accumulation of potassium in the blood, posing a risk of cardiac arrest. Prompt treatment to lower potassium levels is crucial to prevent cardiac complications in this situation.

5. The client is receiving intravenous (IV) morphine for pain control. Which assessment finding requires the most immediate intervention?

• A. Drowsiness.
• B. Itching.
• C. Nausea.
• D. Respiratory rate of 8 breaths per minute.

Correct answer: D

Rationale: A respiratory rate of 8 breaths per minute indicates severe respiratory depression, a life-threatening side effect of opioid therapy. Immediate intervention is crucial to prevent respiratory failure. Monitoring and managing respiratory status are critical in clients receiving opioids to prevent adverse events. Drowsiness, itching, and nausea are common side effects of morphine but are not as immediately life-threatening as severe respiratory depression.
