Question 1 of 5
The nurse is caring for a client who is intubated and on mechanical ventilation. Which action is most effective in preventing ventilator-associated pneumonia (VAP)?
Correct Answer: B
Rationale: The correct answer is B: Providing oral care with chlorhexidine. This is because oral care helps reduce the bacteria in the mouth that can be aspirated into the lungs, leading to VAP. Regular oral care with chlorhexidine can prevent colonization of harmful bacteria in the oral cavity, reducing the risk of VAP. Administering antibiotics won't prevent VAP but treat infections. Suctioning every hour can increase the risk of infection, and elevating the head of the bed to 15 degrees may help prevent aspiration but is not as effective as proper oral care in preventing VAP.
Question 2 of 5
A client with a history of COPD reports increasing dyspnea. What is the nurse's priority assessment?
Correct Answer: A
Rationale: The correct answer is A: Oxygen saturation levels. This is the priority assessment because in a client with a history of COPD experiencing increasing dyspnea, it is crucial to assess their oxygen saturation levels to determine if they are hypoxic. Hypoxia can exacerbate COPD symptoms and lead to respiratory distress. Monitoring oxygen saturation levels helps in assessing the effectiveness of respiratory interventions. Choice B (Heart rate and blood pressure) is important but not the priority as hypoxia can directly impact these vital signs. Choice C (Capillary refill time) is more relevant for assessing perfusion in cardiovascular conditions. Choice D (Level of consciousness) is important but assessing oxygen saturation levels takes precedence in a client with COPD and worsening dyspnea.
Question 3 of 5
The nurse is evaluating the effectiveness of a bronchodilator for a client with asthma. Which finding indicates improvement?
Correct Answer: A
Rationale: The correct answer is A: Decreased wheezing on auscultation. Wheezing is a common symptom of asthma due to narrowed airways. Improvement in asthma would lead to decreased wheezing as the airways open up, allowing for better airflow. This indicates that the bronchodilator is effectively working to dilate the airways and improve respiratory function. Choice B: Respiratory rate increased to 24 breaths per minute is incorrect as an increased respiratory rate could indicate respiratory distress or worsening of asthma symptoms. Choice C: Heart rate increased to 110 beats per minute is incorrect as an increased heart rate could indicate stress or anxiety, not necessarily improvement in asthma. Choice D: Mild hand tremors reported by the client is incorrect as hand tremors are a common side effect of bronchodilators and not a direct indicator of asthma improvement.
Question 4 of 5
A patient with a chronic cough is scheduled to have a bronchoscopy with biopsy. Which intervention will the nurse implement directly after the procedure?
Correct Answer: C
Rationale: The correct answer is C: Keep the patient NPO until the gag reflex returns. After a bronchoscopy with biopsy, the patient's throat and gag reflex may be impaired due to the procedure and anesthesia. Keeping the patient NPO until the gag reflex returns is crucial to prevent aspiration and ensure safe swallowing. Encouraging clear liquids (A) may pose a risk of aspiration if the gag reflex is not intact. Bed rest (B) may not be necessary unless there are specific complications. Maintaining the head of the bed elevated (D) is generally advised for respiratory comfort but is not the immediate priority post-procedure.
Question 5 of 5
A patient is diagnosed with an acute asthma attack. Which medication should the nurse administer first?
Correct Answer: B
Rationale: The correct answer is B: Albuterol (Ventolin HFA) 2.5 mg per nebulizer. In an acute asthma attack, the priority is to quickly open the airways to improve breathing. Albuterol is a short-acting beta agonist that acts rapidly to bronchodilate and relieve bronchospasm. Administering it via nebulizer allows for fast delivery and effective relief. Methylprednisolone (A) is a corticosteroid that helps reduce inflammation but works more slowly and is typically given after initial bronchodilator therapy. Salmeterol (C) is a long-acting beta agonist not used for immediate relief in acute attacks. Ipratropium (D) is an anticholinergic that can also help with bronchodilation but is not the first-line treatment for acute asthma exacerbations.
