Extract:
Question 1 of 5
Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate?
Correct Answer: A
Rationale: PEEP maintains alveolar patency at the end of expiration, preventing collapse and improving oxygenation.
Question 2 of 5
A nurse is suctioning the endotracheal tube of a client who is on a ventilator. The client's heart rate increases from 86/min to 110/min and becomes irregular. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Pre-oxygenation prevents hypoxemia during suctioning, which can cause tachycardia and arrhythmias.
Question 3 of 5
A nurse is caring for a client who has pericarditis and reports feeling a new onset of palpitations and shortness of breath. Which of the following assessments should indicate to the nurse that the client may have developed atrial fibrillation?
Correct Answer: D
Rationale: A pulse deficit between apical and radial pulses indicates irregular ventricular contractions typical of atrial fibrillation.
Question 4 of 5
A nurse in an urgent care center is assessing a client who reports a sudden onset of irregular palpitations, fatigue, and dizziness. The nurse finds a rapid and irregular heart rate with a significant pulse deficit. Which of the following dysrhythmias should the nurse expect to find on the ECG?
Correct Answer: C
Rationale: Atrial fibrillation causes an irregularly irregular heart rhythm, leading to palpitations, fatigue, dizziness, and a pulse deficit due to inconsistent ventricular contractions.
Question 5 of 5
Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate?
Correct Answer: A
Rationale: PEEP maintains alveolar patency at the end of expiration, preventing collapse and improving oxygenation.
