Nursing Elites

1. After 5 days of diuretic therapy with 20mg of furosemide (Lasix) daily, a patient begins to exhibit fatigue, muscle cramping, and muscle weakness. These symptoms probably indicate that the patient is experiencing:

• A. Hypokalemia
• B. Hyperkalemia
• C. Anorexia
• D. Dysphagia

Correct answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

2. A healthcare professional in the emergency department is assessing a client who has a suspected flail chest. Which of the following findings should the professional not expect?

• A. Bradycardia
• B. Cyanosis
• C. Hypotension
• D. Dyspnea

Correct answer: A

Rationale: Bradycardia is not typically associated with a flail chest. Flail chest is characterized by paradoxical chest wall movement, respiratory distress, and hypoxia, but it does not usually cause bradycardia. The other options, such as cyanosis (bluish discoloration of the skin due to poor oxygenation), hypotension (low blood pressure), and dyspnea (difficulty breathing), are commonly seen in patients with flail chest due to the underlying respiratory compromise.

3. Which natural body defense plays an active role in preventing infection?

• A. Yawning
• B. Body hair
• C. Hiccupping
• D. Rapid eye movements

Correct answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

4. While teaching a newly hired nurse about varicella, a nurse in a pediatric clinic should include which of the following information?

• A. Children who have varicella are contagious until vesicles are crusted.
• B. Children who have varicella should receive the varicella (chickenpox) vaccine.
• C. Children who have varicella should be placed in airborne precautions.
• D. Children who have varicella are contagious 1-2 days before the rash appears.

Correct answer: A

Rationale: Children with varicella (chickenpox) are contagious until all vesicles are crusted over. The contagious period starts 1-2 days before the rash appears and continues until all lesions are dried and crusted. It is important to educate healthcare providers about the contagious period to prevent the spread of the virus to susceptible individuals.

5. In the emergency department, a nurse is assessing a client involved in a motor vehicle crash. Findings include absent breath sounds in the left lower lobe with dyspnea, blood pressure 118/68 mm Hg, heart rate 124/min, respirations 38/min, temperature 38.6 C (101.4 F), and SaO2 92% on room air. What action should the nurse take first?

• A. Obtain a chest X-ray.
• B. Prepare for chest tube insertion.
• C. Administer oxygen via high-flow mask.
• D. Initiate IV access.

Correct answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.
