A nurse is caring for a client on mechanical ventilation and finds the client agitated and thrashing about. What action by the nurse is most appropriate?
- A. Assess the cause of the agitation
- B. Reassure the client that he or she is safe
- C. Restrain the client's hands
- D. Sedate the client immediately

The nurse caring for mechanically ventilated clients uses best practices to prevent ventilator-associated pneumonia. What actions are included in this practice? (Select all that apply.)
- A. Adherence to proper hand hygiene
- B. Administering anti-ulcer medication
- C. Elevating the head of the bed
- D. Providing oral care per protocol
- E. Suctioning the client on a regular schedule
Correct Answer: A,B,C,D

A client has been brought to the emergency department with a life-threatening chest injury. What action by the nurse takes priority?
- A. Apply oxygen at 100%
- B. Assess the respiratory rate
- C. Ensure a patent airway
- D. Start two large-bore IV lines
Correct Answer: C
Rationale: For chest trauma, the priority follows the ABCs (airway, breathing, circulation). Ensuring a patent airway is the first step to stabilize the client.
A client is on mechanical ventilation and the client's spouse wonders why ranitidine (Zantac) is needed since the client only has lung problems. What response by the nurse is best?
- A. It will increase the motility of the gastrointestinal tract
- B. It will keep the gastrointestinal tract functioning normally
- C. It will prepare the gastrointestinal tract for enteral feedings
- D. It will prevent ulcers from the stress of mechanical ventilation
Correct Answer: D
Rationale: Ranitidine, a histamine blocker, is used prophylactically to prevent stress ulcers, which are common in mechanically ventilated clients due to physiological stress.
A student nurse is preparing to administer enoxaparin (Lovenox) to a client. What action by the student requires immediate intervention by the supervising nurse?
- A. Assessing the client's platelet count
- B. Choosing an 18-gauge, 2-inch needle
- C. Not aspirating prior to injection
- D. Swabbing the injection site with alcohol
Correct Answer: B
Rationale: Enoxaparin is administered subcutaneously, requiring a smaller needle (e.g., 25"?26 gauge, 5/8 inch). An 18-gauge, 2-inch needle is inappropriate and could cause harm.
A nurse answers a call light and finds a client anxious, short of breath, reporting chest pain, and having a blood pressure of 88/52 mm Hg. What action by the nurse is best?
- A. Administer oxygen at 2 L/min via nasal cannula
- B. Obtain a STAT chest X-ray
- C. Prepare to administer thrombolytic therapy
- D. Monitor the client's blood pressure every 15 minutes
Correct Answer: C
Rationale: The client's symptoms of anxiety, shortness of breath, chest pain, and hypotension suggest a pulmonary embolism, which can significantly impair gas exchange. Thrombolytic therapy is indicated for a large pulmonary embolism causing hemodynamic instability, as it can dissolve the clot and restore oxygenation.
