Question 1 of 5
A nurse is caring for a client in a cardiac unit. Using the five criteria for ECG analysis information, the nurse interprets the client's ECG as which of the following rhythm interpretations?
Correct Answer: D
Rationale: A heart rate of 102 bpm indicates tachycardia. Regular rhythm, P waves present, PR interval 0.20 sec, and QRS 0.10 sec indicate normal sinus conduction, making it sinus tachycardia.
Question 2 of 5
The nurse is caring for a client diagnosed with Raynaud's phenomena. The nurse will prioritize educating the client about implementing which intervention?
Correct Answer: A
Rationale: Avoiding cold exposure is critical because cold can trigger vasospasms of small arteries in the fingers and toes, leading to pain, pallor, cyanosis, and numbness. Stress is a major trigger for Raynaud's episodes, loose warm gloves are recommended, and caffeine is a vasoconstrictor that can worsen symptoms.
Question 3 of 5
A nurse is reinforcing teaching with a client regarding reduction of risk factors for coronary artery disease. Which of the following statements by the client indicates an understanding of the teaching? (Select all that apply.)
Correct Answer: A,B,C
Rationale: Limiting fast foods reduces unhealthy fats, monitoring weight helps manage cardiovascular risks, and stopping smoking significantly lowers CAD risk. Moderate alcohol consumption may be beneficial, and exercise should be increased, not limited.
Question 4 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 5 of 5
A nurse is caring for a client whose arterial blood gas results show a pH of 7.5, an HCO3 of 22, and a PaCO2 of 25 mm Hg. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Correct Answer: B
Rationale: A pH of 7.5 indicates alkalosis, and a low PaCO2 of 25 mm Hg suggests hyperventilation, pointing to respiratory alkalosis. A would show elevated HCO3, C would have low pH and HCO3, and D would have low pH and high PaCO2.
