Nursing Elites

1. The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?

• A. Pursed-lip breathing
• B. Hyperresonance on percussion
• C. Bradycardia
• D. High-pitched inspiratory crackles

Correct answer: A

Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.

2. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?

• A. Neutralizes stomach acid
• B. Reduces gastric acid production
• C. Forms a protective barrier over ulcers
• D. Increases gastric mucus production

Correct answer: B

Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.

3. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?

• A. Administer bronchodilator therapy as prescribed.
• B. Inhale the medication slowly while pressing down on the inhaler.
• C. Position the client in a high-Fowler's position.
• D. Increase the oxygen flow rate.

Correct answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.

4. A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?

• A. Administer insulin as prescribed
• B. Provide a carbohydrate-controlled snack
• C. Encourage physical activity
• D. Recheck the blood sugar

Correct answer: A

Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.

5. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
