1. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
2. A young client who is being taught how to use an inhaler for symptoms of asthma tells the nurse about the intention to use the inhaler but plans to continue smoking cigarettes. In evaluating the client’s response, what is the best initial action by the nurse?
- A. Explain the risks of smoking with asthma.
- B. Revise the plan of care.
- C. Encourage the client to reduce smoking gradually.
- D. Provide resources for smoking cessation.
Correct answer: B
Rationale: The best initial action by the nurse is to revise the plan of care. This is necessary to address the client's intention to continue smoking and ensure that appropriate support and education are provided. Choice A is not the best initial action as the client is already aware of the risks of smoking with asthma. Choice C might not be effective as the client's intention to continue smoking poses a significant risk to their health. Choice D, providing resources for smoking cessation, is important but revising the plan of care should come first to address the immediate concern.
3. The nurse determines that an adult client who is admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.4°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/68 mmHg. Which action should the nurse implement?
- A. Check the BP every five minutes for one hour.
- B. Raise the HOB 60 to 90 degrees.
- C. Ask the client to cough and deep breathe.
- D. Take the client’s temperature using another method.
Correct answer: D
Rationale: Taking the temperature using another method is essential in this situation to verify if the low reading is accurate and requires further intervention. The tympanic temperature of 94.6°F may be inaccurate due to various factors such as improper technique or environmental conditions. Checking the blood pressure every five minutes for one hour (Choice A) is not the priority in this case as the low blood pressure reading alone does not necessitate such frequent monitoring. Raising the head of the bed 60 to 90 degrees (Choice B) is not directly related to addressing the low temperature and blood pressure. Asking the client to cough and deep breathe (Choice C) is a general intervention that may not directly address the specific concern of the low temperature reading.
4. The nurse is providing discharge teaching for a client with heart failure. Which instruction should be included to prevent fluid overload?
- A. Weigh yourself daily and report a gain of 2 pounds in 24 hours
- B. Increase fluid intake to stay hydrated
- C. Consume a high-sodium diet to retain fluids
- D. Engage in vigorous exercise daily
Correct answer: A
Rationale: The correct answer is A: 'Weigh yourself daily and report a gain of 2 pounds in 24 hours.' Daily weight monitoring is crucial for detecting fluid retention early in clients with heart failure. Reporting a gain of 2 pounds in 24 hours can indicate fluid overload, prompting timely intervention. Choice B is incorrect because increasing fluid intake can exacerbate fluid overload in clients with heart failure. Choice C is incorrect as a high-sodium diet can worsen fluid retention. Choice D is incorrect as vigorous exercise can strain the heart and worsen heart failure symptoms.
5. The healthcare provider is assessing a client with a chest tube. Which finding indicates that the chest tube is functioning properly?
- A. Continuous bubbling in the water seal chamber
- B. Tidaling in the water seal chamber
- C. Absence of drainage in the collection chamber
- D. Fluid level in the suction control chamber is below the prescribed level
Correct answer: B
Rationale: Tidaling in the water seal chamber indicates proper chest tube function. Tidaling refers to the rise and fall of fluid in the water seal with inhalation and exhalation, demonstrating the patency of the system. Continuous bubbling (Choice A) in the water seal chamber indicates an air leak. Absence of drainage in the collection chamber (Choice C) is not a desired finding as it suggests no drainage is occurring. A fluid level below the prescribed level in the suction control chamber (Choice D) may indicate inadequate suction.
