Extract:
Question 1 of 5
A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor. The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T wave.
Correct Answer: A
Rationale: The T wave, representing ventricular repolarization, is the prominent upward wave following the QRS complex. Hyperkalemia may cause tall, peaked T waves.
Question 2 of 5
The nursing assistant reports to the registered nurse (RN) that an older adult client who has been alert and oriented has become increasingly confused over the past 3 hours. What would be the best nursing action to perform next?
Correct Answer: A
Rationale: Hypoxia is a common cause of acute confusion in older adults, making oxygen saturation a priority assessment. B, C, and D are secondary to addressing potential hypoxia.
Question 3 of 5

Correct Answer: B
Rationale: Cough, sputum changes, dyspnea, and chest pain are hallmark symptoms of pneumonia due to lung infection and inflammation. A is related to hypoglycemia, C is more indicative of tuberculosis, and D suggests gastrointestinal issues.

Question 5 of 5
A nurse is reviewing blood pressure classifications with a group of nurses at an in-service meeting. Which of the following should the nurse include as a risk factor for the development of hypertension?
Correct Answer: B
Rationale: Obstructive sleep apnea contributes to hypertension by causing repeated episodes of hypoxia, sympathetic nervous system activation, and increased vascular resistance. High potassium intake helps lower blood pressure, HDL of 70 mg/dL is protective, and benazepril treats hypertension, not causes it.
