Lidocaine is a medication frequently ordered for the client experiencing
- A. Atrial tachycardia
- B. Ventricular tachycardia
- C. Heart block
- D. Ventricular bradycardia
Correct Answer: B
Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

How should Lasix be administered to prevent hypotension?
- A. By administering it over 1-2 minutes
- B. By hanging it IV piggyback
- C. With normal saline only
- D. By administering it through a venous access device
Correct Answer: A
Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.
After a client undergoes a left lower lobe lung resection for lung cancer, which post-operative measure would typically be included in the plan?
- A. Closed chest drainage
- B. A tracheostomy
- C. A mediastinal tube
- D. Percussion vibration and drainage
Correct Answer: A
Rationale: After a lung resection, such as the removal of the left lower lobe for lung cancer, closed chest drainage is a common post-operative measure to help drain any excess air or fluid from the chest cavity. A tracheostomy is not typically needed for this procedure, so choice B is incorrect. Similarly, a mediastinal tube is not routinely inserted following a left lower lobe lung resection, making choice C incorrect. Percussion vibration and drainage are not indicated for this type of surgery, so choice D is also incorrect. Therefore, the correct answer is closed chest drainage.
The nurse is making assignments for the day. Which client should be assigned to the pregnant nurse?
- A. The client receiving linear accelerator radiation therapy for lung cancer
- B. The client with a radium implant for cervical cancer
- C. The client who has just been administered soluble brachytherapy for thyroid cancer
- D. The client who returned from placement of iridium seeds for prostate cancer
Correct Answer: A
Rationale: The pregnant nurse should not be assigned to any client with radioactivity present. The client receiving linear accelerator therapy is the correct choice because the radiation stays in the department, and the client is not radioactive. Choices B, C, and D involve clients who are radioactive or pose a risk due to radioactivity. The client with a radium implant for cervical cancer (choice B) is radioactive, the client who has just been administered soluble brachytherapy for thyroid cancer (choice C) is radioactive for approximately 72 hours, and the client who returned from placement of iridium seeds for prostate cancer (choice D) is also radioactive, especially right after the procedure. These options are not suitable for assignment to the pregnant nurse.
The nurse is assisting the RN with discharge instructions for a client with an implantable defibrillator. What discharge instruction is essential?
- A. "You can eat food prepared in a microwave."?
- B. "You should avoid moving the shoulder on the side of the defibrillator site for 6 weeks."?
- C. "You should use your cellphone on your right side."?
- D. "You will be able to fly on a commercial airliner with the defibrillator in place."?
Correct Answer: C
Rationale: The essential discharge instruction for a client with an implantable defibrillator is to use any battery-operated machinery on the opposite side, including cellphones. This is to prevent interference with the device. Additionally, the client should monitor their pulse rate and report any dizziness or fainting, which could indicate issues with the defibrillator. Choices A, B, and D are incorrect because clients with implantable defibrillators can eat food prepared in the microwave, move their shoulder on the affected side after the initial healing period, and are allowed to fly on commercial airliners with the defibrillator in place.
A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure?
- A. Bradycardia
- B. Tachycardia
- C. Premature ventricular beats
- D. Heart block
Correct Answer: A
Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.
