1. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?

• A. 300 mL
• B. 480 mL
• C. 800 mL
• D. 950 mL

Correct answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.

2. The provider requests the nurse to start an infusion of an inotropic agent on a client. How should the nurse explain the action of these drugs to the client and spouse?

• A. It constricts vessels, improving blood flow.
• B. It dilates vessels, which lessens the work of the heart.
• C. It increases the force of the heart's contractions.
• D. It slows the heart rate down for better filling.

Correct answer: C

Rationale: An inotropic agent is a medication that increases the force of the heart's contractions, which helps improve cardiac output. Choice A and B are incorrect as inotropic agents do not constrict or dilate vessels. Choice D is also incorrect as inotropic agents do not slow down the heart rate but rather enhance the heart's contractility.

3. A nurse working on a cardiac unit delegated taking vital signs to an experienced unlicensed assistive personnel (UAP). Four hours later, the nurse notes the client's blood pressure is much higher than previous readings & the client's mental status has changed. What action by the nurse would most likely have prevented this negative outcome?

• A. Determining if the UAP knew how to take blood pressure
• B. Double-checking the UAP by taking another blood pressure
• C. Providing more appropriate supervision of the UAP
• D. Taking the blood pressure instead of delegating the task

Correct answer: C

Rationale: The most likely action by the nurse that would have prevented the negative outcome is providing more appropriate supervision of the UAP. Supervision is essential in delegation as it involves directing, evaluating, and following up on delegated tasks. By providing adequate supervision, the nurse can ensure that tasks are performed correctly and promptly identify any issues or abnormalities, such as a significant change in vital signs or the client's mental status. This proactive approach can help prevent adverse outcomes and enhance patient safety.

4. The client with a chest tube after a coronary artery bypass graft has significantly slowed drainage. What action is most important for the nurse to take?

• A. Increase the setting on the suction.
• B. Notify the provider immediately.
• C. Re-position the chest tube.
• D. Take the tubing apart to assess for clots.

Correct answer: B

Rationale: If the drainage from the chest tube decreases significantly, it may indicate a blockage by a clot, potentially leading to cardiac tamponade. The nurse's priority action should be to notify the healthcare provider immediately for further evaluation and intervention. Increasing suction, re-positioning the chest tube, or disassembling the tubing independently are not appropriate actions without healthcare provider guidance in this situation.

5. When reviewing the provider's orders, a nurse recognizes that clarification is needed for which of the following medications in a client experiencing an exacerbation of asthma?

• A. Propranolol
• B. Theophylline
• C. Montelukast
• D. Prednisone

Correct answer: A

Rationale: The correct answer is Propranolol. Propranolol is a beta-blocker that can potentially exacerbate asthma symptoms due to its mechanism of action. It can cause bronchoconstriction, which is harmful for a client experiencing an asthma exacerbation. Theophylline, Montelukast, and Prednisone are commonly used in the treatment of asthma exacerbations and would not typically require clarification in this context.
