Extract:
Question 1 of 5
A nurse is performing an ECG on a client who is experiencing chest pain. Which of the following statements should the nurse make?
Correct Answer: B
Rationale: Electrodes applied to the chest and extremities detect the electrical activity of the heart, necessary for accurate ECG readings and diagnosing potential cardiac issues.
Question 2 of 5
Review the EKG shown below, which displays rapid, erratic electrical impulses causing ineffective quivering instead of coordinated contraction. What should be the nurse's initial intervention?
Correct Answer: B
Rationale: Initiating CPR and preparing for defibrillation are crucial for ventricular fibrillation, a life-threatening arrhythmia requiring immediate intervention.
Question 3 of 5
A nurse is providing discharge teaching to a client who has peripheral arterial disease (PAD). Which of the following instructions should the nurse include in the teaching?
Correct Answer: D
Rationale: A warm environment helps to prevent vasoconstriction. Cold temperatures can cause the arteries to constrict, reducing blood flow to the extremities. A consistent warm environment supports improved blood circulation.
Question 4 of 5
A client who has a history of myocardial infarction (MI) is prescribed aspirin 325 mg. The nurse recognizes that the aspirin is given due to which of the following actions of the medication?
Correct Answer: B
Rationale: Aspirin acts as an antiplatelet agent by irreversibly inhibiting cyclooxygenase-1 (COX-1) enzyme, reducing thromboxane A2 production, thereby preventing platelet aggregation and thrombus formation.
Question 5 of 5
A nurse is caring for a client who reports an area of redness, warmth, tenderness and pain in the right calf. The nurse anticipates which of the following orders when notifying the provider of this finding?
Correct Answer: C
Rationale: Venous duplex ultrasound is the gold standard for diagnosing DVT as it visualizes blood flow and identifies thrombi within the veins, providing accurate and non-invasive detection.
