A nurse is caring for a client who has developed a thrombus and is receiving heparin by continuous N infusion. The client asks the nurse how long will it take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
"Heparin does not dissolve clots. It stops new clots from forming"
"Heparin will begin dissolving clots over the next 24 hours
"A pharmacist would be a better fit to answer that question.
"It usually takes heparin at least 3 to 4 days to reach a therapeutic blood level."
The Correct Answer is A
Choice A rationale: Heparin is an anticoagulant that prevents new clots from forming but does not dissolve existing clots23.
Choice B rationale: Heparin does not directly dissolve clots23.
Choice C rationale: While a pharmacist can provide medication information, it is incorrect to say they would be a better fit to answer this question as nurses are trained in medication education23.
Choice D rationale: While it’s true that it takes time for heparin to reach a therapeutic blood level, this statement could be misleading because heparin does not dissolve clots23.
So, the correct answer is Choice A, after analysing all choices.

Correct Answer is B
Explanation
Choice A rationale: Epinephrine is a potent vasoconstrictor and is typically used in emergency situations such as cardiac arrest. It is not the first-line treatment for symptomatic bradycardia1.
Choice B rationale: Atropine is the first-line medication for the treatment of bradycardia. It increases the heart rate by blocking the effects of the vagus nerve on the heart1.
Choice C rationale: Adenosine is primarily used to treat supraventricular tachycardia, not bradycardia1.
Choice D rationale: Verapamil is a calcium channel blocker used to treat high blood pressure, angina, and certain heart rhythm disorders, not typically used for bradycardia1.
Correct Answer is D
Explanation
Choice A rationale: The “ANALYZE” button is typically used to allow the defibrillator to analyze the heart rhythm. It would not ensure that the electricity is delivered on the R wave6.
Choice B rationale: The “SHOCK” button is used to deliver a shock during defibrillation or cardioversion. However, it does not specifically ensure that the shock is delivered on the R wave6.
Choice C rationale: The “ON” button is typically used to turn the device on or off. It does not control the timing of the electrical delivery6.
Choice D rationale: The “SYNC” button is used in synchronized cardioversion to match the delivery of the shock to the R wave of the ECG, which is the peak of the electrical wave during which the ventricular cells are depolarized6.
So, the correct answer is D, after analysing all choices.
