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 A
Explanation
The first action the nurse should take when caring for a patient with gastrointestinal bleeding is to assess orthostatic blood pressure. This can help determine the extent of the patient’s blood loss and whether they are experiencing hypovolemia.
Correct Answer is C
Explanation
Choice A rationale
Encouraging self-care is important, but it may not be the immediate priority if the patient is exhibiting manic behavior and has recently experienced significant personal stressors.
Choice B rationale
Assisting the patient in identifying coping behaviors is a key part of treatment, but it may not be the immediate priority if the patient is at risk of self-harm.
Choice C rationale
Preventing self-directed violence is the priority action. Patients exhibiting manic behavior may have impaired judgment and impulse control, putting them at risk of self-harm.
Choice D rationale
Identifying support systems is important, but it may not be the immediate priority if the patient is at risk of self-harm.
