Extract:
Question 1 of 5
A nurse is reviewing the EKG strip of a client who is hypertensive and is complaining of muscle weakness. Which of the following abnormalities on the clients EKG should the nurse interpret as a sign of hyperkalemia?
Correct Answer: A
Rationale: Peaked T waves are a classic sign of hyperkalemia on an EKG. As potassium levels rise, the T waves become taller, more pointed, and narrow, indicating changes in the heart's electrical conduction. This is one of the earliest and most characteristic EKG changes seen with hyperkalemia.
Question 2 of 5
A client with a diagnosis of multiple sclerosis is scheduled to receive plasmapheresis treatments. A nurse explains to the client's spouse that the purpose of plasmapheresis is to:
Correct Answer: D
Rationale: Plasmapheresis works by removing circulating antibodies from the bloodstream. In multiple sclerosis, the immune system mistakenly targets the myelin sheath, and plasmapheresis helps to remove the antibodies responsible for this autoimmune response. This can provide temporary relief of symptoms during acute flare-ups of MS by reducing the immune system's attack on the nervous system.
Question 3 of 5
A nurse is caring for a client who develops the rhythm below. The client is unresponsive, pulseless, and apneic. Which of the following actions should the nurse expect to do first?
Correct Answer: A
Rationale: Defibrillation is the priority for ventricular fibrillation, a life-threatening arrhythmia, to restore a perfusing rhythm in an unresponsive, pulseless client.
Question 4 of 5
The nurse supervises the care of a patient with a temporary radioactive cervical implant. Which action by unlicensed assistive personnel (UAP), if observed by the nurse, would require immediate intervention?
Correct Answer: A
Rationale: This action requires immediate intervention because of the potential radiation exposure to the UAP. A temporary radioactive cervical implant involves placing a radioactive source in or near the patient's cervix. Prolonged close contact increases the risk of radiation exposure.
Question 5 of 5
A nurse is teaching a client who has angina pectoris about starting therapy with nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: C
Rationale: Taking nitroglycerin at the first sign of chest pain ensures rapid relief by dilating coronary arteries.
