Question 1 of 5
A nurse is caring for a client in the intensive care unit who suddenly becomes confused and agitated. The nurse recognizes these manifestations are likely related to a condition with which of the following characteristics?
Correct Answer: C
Rationale: Confusion and agitation in the ICU are often reversible, commonly caused by factors like medications, infections, or metabolic disturbances, which can be addressed to restore baseline mental status.
Question 2 of 5
A nurse is providing postoperative care to a client who lost 800 mL of blood during surgery. The client's blood pressure has been steadily decreasing over the past 2 hr. Which of the following categories of shock should the nurse recognize is occurring?
Correct Answer: A
Rationale: Significant blood loss (800 mL) leads to hypovolemic shock, characterized by decreased circulating blood volume and inadequate tissue perfusion.
Question 3 of 5
A nurse is analyzing a client's electrocardiogram (ECG) strip and identifies the following information: Heart rate: $92 / \mathrm{min}$, Rhythm: Irregular, P wave: Unable to identify, PR interval: Unable to measure, QRS duration: 0.10 seconds. Based upon this information, the nurse should interpret the client's rhythm as indicating which of the following?
Correct Answer: A
Rationale: Atrial fibrillation is indicated by an irregular rhythm, absent P waves, and variable heart rate, matching the ECG findings. Sinus bradycardia has a regular rhythm and heart rate <60 bpm. Supraventricular tachycardia has a regular rhythm and rate >100 bpm. First-degree heart block has a prolonged PR interval and regular rhythm.
Question 4 of 5
The nurse is providing care to a client who has survived cardiac arrest. Which of the following manifestations should alert the nurse to the development of PCAS?
Correct Answer: A
Rationale: Decreased circulation to the kidneys is a manifestation of post-cardiac arrest syndrome (PCAS) due to systemic ischemia/reperfusion injury, potentially leading to acute kidney injury.
Question 5 of 5
A nurse is planning care for a client who has suspected cardiac tamponade. Which of the following diagnostic tests should the nurse anticipate the provider to order first?
Correct Answer: C
Rationale: An echocardiogram is the most appropriate initial diagnostic test for suspected cardiac tamponade. It provides real-time imaging of the heart and can detect pericardial effusion, collapse of the right atrium and ventricle during diastole (diastolic collapse), and signs of hemodynamic compromise.
