Nursing Elites

1. A client presents with shortness of breath, pain in the lung area, and a recent history of starting birth control pills and smoking. Vital signs include a heart rate of 110/min, respiratory rate of 40/min, and blood pressure of 140/80 mm Hg. Arterial blood gases reveal pH 7.50, PaCO2 29 mm Hg, PaO2 60 mm Hg, HCO3 20 mEq/L, and SaO2 86%. What is the priority nursing intervention?

• A. Prepare for mechanical ventilation.
• B. Administer oxygen via face mask.
• C. Prepare to administer a sedative.
• D. Assess for indications of pulmonary embolism.

Correct answer: B

Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.

2. Which action should the nurse take to reduce the risk of ventilator-associated pneumonia in a client with an endotracheal tube receiving mechanical ventilation?

• A. Position the head of the client's bed flat
• B. Turn the client every 4 hours
• C. Brush the client's teeth with a suction toothbrush every 12 hours
• D. Provide humidity by maintaining moisture within the ventilator tubing

Correct answer: C

Rationale: Ventilator-associated pneumonia (VAP) is a common complication in clients receiving mechanical ventilation. Oral hygiene is crucial in reducing the risk of VAP. Brushing the client's teeth with a suction toothbrush every 12 hours helps prevent bacterial colonization in the oral cavity, which can be aspirated into the lungs. Positioning the head of the bed flat can increase the risk of aspiration. Turning the client every 4 hours is important for preventing pressure ulcers but not directly related to reducing VAP. Providing humidity in the ventilator tubing helps maintain airway moisture but does not directly address the risk of VAP.

3. During an admission assessment of a client with COPD and emphysema complaining of a frequent productive cough and shortness of breath, what assessment finding should the nurse anticipate?

• A. Respiratory alkalosis
• B. Increased anteroposterior diameter of the chest
• C. Oxygen saturation level 96%
• D. Petechiae on chest

Correct answer: B

Rationale: COPD and emphysema are chronic respiratory conditions that can lead to changes in the shape of the chest. In clients with COPD, the anteroposterior diameter of the chest often increases, giving a barrel chest appearance. This change in chest shape is due to hyperinflation of the lungs and is a common physical finding in clients with COPD and emphysema. The other options are not typically associated with COPD and emphysema. Respiratory alkalosis is not a common finding in these clients. An oxygen saturation level of 96% is within the normal range and does not specifically relate to COPD. Petechiae on the chest are not typically associated with COPD or emphysema.

4. A client reports a headache and vertigo after turning on his furnace for the first time this season. The nurse should suspect which of the following conditions?

• A. Carbon monoxide poisoning
• B. Heat stroke
• C. Hypersensitivity reaction
• D. Oxygen toxicity

Correct answer: A

Rationale: When a client reports headache and vertigo after turning on the furnace for the first time, it suggests carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be released by malfunctioning heating systems. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. It is crucial for the nurse to suspect this condition promptly to ensure the client's safety and well-being.

5. When caring for a client with acute renal failure, which laboratory value is most important to monitor?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum chloride

Correct answer: B

Rationale: In acute renal failure, monitoring serum potassium is crucial because impaired kidney function can lead to hyperkalemia, which can result in life-threatening cardiac dysrhythmias. Elevated potassium levels need close monitoring and prompt interventions to prevent serious complications.
