1. 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.
2. A client with a chest tube connected to a closed drainage system needs to be transported to the x-ray department. Which of the following actions should the nurse take?
- A. Clamp the chest tube prior to transferring the client to a wheelchair.
- B. Disconnect the chest tube from the drainage system during transport.
- C. Keep the drainage system below the level of the client's chest at all times.
- D. Empty the collection chamber prior to transport.
Correct answer: C
Rationale: When transporting a client with a chest tube connected to a closed drainage system, it is crucial to keep the drainage system below the level of the client's chest at all times. This positioning prevents the backflow of drainage into the client's chest, reducing the risk of complications. Clamping the chest tube, disconnecting it from the drainage system, or emptying the collection chamber are incorrect actions and can potentially harm the client or lead to complications.
3. A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: A
Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.
4. How does the pain of a myocardial infarction (MI) differ from stable angina?
- A. Accompanied by shortness of breath
- B. Feelings of fear or anxiety
- C. Lasts about 3-5 minutes
- D. Relieved by taking nitroglycerin
Correct answer: A
Rationale: The pain of an MI is often accompanied by shortness of breath and feelings of fear or anxiety. It typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Unlike stable angina, the pain of an MI occurs without a known cause such as exertion.
5. When preparing a client for transfer to the ICU for placement of a pulmonary artery catheter, the nurse should explain that this catheter is used to monitor which of the following conditions?
- A. Intracranial pressure
- B. Spinal cord perfusion
- C. Renal function
- D. Hemodynamic status
Correct answer: D
Rationale: A pulmonary artery catheter is primarily used to monitor hemodynamic status. It provides essential information on cardiac output, preload, afterload, and overall cardiovascular function. This data helps healthcare providers manage the client's fluid status, cardiac function, and guide treatment interventions in critically ill patients. Monitoring intracranial pressure, spinal cord perfusion, or renal function would require different monitoring devices and techniques, not a pulmonary artery catheter.
