Question 1 of 5
The nurse is administering low dose dopamine to a client who is in septic shock. Which physiologic parameter should the nurse use to evaluate a therapeutic response to the dopamine?
Correct Answer: C
Rationale: Low-dose dopamine increases renal blood flow, improving urinary output, indicating effective renal perfusion.
Question 2 of 5
A client admitted to the intensive care unit (ICU) with acute respiratory distress syndrome (ARDS) is intubated and placed on assist-control mechanical ventilation. When suctioning pulmonary secretions from the endotracheal tube (ETT) using a closed suction system, which action should the nurse implement to ensure that the client receives adequate oxygenation?
Correct Answer: B
Rationale: Pre-oxygenating by delivering additional breaths via the ventilator prevents hypoxia during suctioning, ensuring adequate oxygenation.

Question 3 of 5
Based on the ABG values, the nurse knows that the client has [condition] related to [cause].
Correct Answer: D,G
Rationale: Uncompensated metabolic acidosis is characterized by a low pH (7.23) and normal PaCOâ‚‚ (37 mmHg), indicating a primary metabolic problem without respiratory compensation. The lack of insulin in type 1 diabetes leads to ketone formation and metabolic acidosis.

Question 4 of 5
A client who is admitted to the intensive care unit (ICU) with acute decompensated heart failure is receiving a continuous infusion of milrinone via a subclavian venous catheter. Which action should the nurse take when preparing to administer the first dose of IV furosemide?
Correct Answer: D
Rationale: Milrinone and furosemide are incompatible due to pH differences, which can cause precipitation. Administering furosemide through a separate IV line ensures safe delivery.
Question 5 of 5
The nurse is monitoring for signs of increased intracranial pressure (ICP) in a client who attempted suicide by jumping from a tenth floor balcony. The client is intubated and mechanically ventilated. Which intervention should the nurse implement to minimize rises in ICP?
Correct Answer: C
Rationale: Clustering too many nursing interventions together can overstimulate the client and cause spikes in ICP. Providing adequate rest periods between activities such as repositioning, suctioning, and assessments allows intracranial pressure to return to baseline levels, helping to prevent sustained increases.
