A nurse in a coronary care unit is admitting a patient who has had CPR following a cardiac arrest.
The patient is receiving lidocaine IV at 2 mg/min.
When the patient asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
Relieves pain.
Slows intestinal motility.
Dissolves blood clots.
Prevents dysrhythmias.
The Correct Answer is D
Choice A rationale
Lidocaine does not primarily serve to relieve pain when administered intravenously. It is primarily used as an antiarrhythmic agent.
Choice B rationale
Lidocaine does not slow intestinal motility. This is not one of its primary actions.
Choice C rationale
Lidocaine does not dissolve blood clots. It is not an anticoagulant.
Choice D rationale
Lidocaine prevents dysrhythmias. It is an antidysrhythmic medication that delays the conduction in the heart and reduces the automaticity of heart tissue.

Correct Answer is ["B","D","E"]
Explanation
Choice A rationale
Standing directly in front of a patient who has a history of anger and aggression can be perceived as threatening and may escalate the situation.
Choice B rationale
Knowing the layout of the facility can help the nurse to plan for safe exits or to put barriers between themselves and the patient if needed.
Choice C rationale
Bringing security for all patient interactions can escalate the situation and should only be done if there is a clear threat to safety.
Choice D rationale
Providing immediate verbal feedback for escalating behavior can help to de-escalate the situation and reassure the patient.
Choice E rationale
Avoiding wearing necklaces during patient care can reduce the risk of injury to the nurse.
Correct Answer is A
Explanation
Choice A rationale
Drinking a full glass of water after taking the medication is a good practice when taking calcium carbonate antacids. This helps to ensure that the medication is fully swallowed and reaches the stomach, where it can neutralize stomach acid.
Choice B rationale
Limiting sodium intake is not directly related to the use of calcium carbonate antacids. While a low-sodium diet may be recommended for other health reasons, it is not a specific recommendation for patients taking this medication.
Choice C rationale
Consuming the medication alongside dairy products to enhance absorption is not recommended. Calcium carbonate antacids can interact with dairy products, potentially leading to an excessive intake of calcium.
Choice D rationale
Reducing dietary fiber to counteract the potential side effect of diarrhea is not a typical recommendation for patients taking calcium carbonate antacids. While calcium carbonate can cause constipation in some people, it does not typically cause diarrhea.
