The nurse and the other members of the team are caring for a client in the ED who converted to ventricular fibrillation (VF). The client was defibrillated unsuccessfully and the client remains in VF. Which medication should the nurse be prepared to administer?
Sodium Bicarbonate
Amiodarone
Epinephrine
Lidocaine
The Correct Answer is C
A. Sodium Bicarbonate is incorrect as it is not a first-line treatment for VF. It may be considered in cases of severe acidosis or hyperkalemia.
B. Amiodarone is incorrect as it is used as an antiarrhythmic, but epinephrine is administered first during cardiac arrest to increase perfusion.
C. Epinephrine is correct because it is the first-line drug given in ventricular fibrillation that persists after defibrillation. It increases coronary and cerebral perfusion and enhances the effectiveness of subsequent defibrillation attempts.
D. Lidocaine is incorrect as it is an antiarrhythmic that may be considered after epinephrine and amiodarone, but it is not the first choice.

Correct Answer is B
Explanation
A. Limiting all nutrients is not recommended for patients on dialysis. While certain nutrients like potassium and phosphorus may need to be restricted, dialysis patients usually require adequate nutrition, especially protein, to support healing and prevent malnutrition.
B. Ensuring an adequate amount of protein is correct. Dialysis patients often experience protein loss through dialysis and need additional protein to prevent catabolism and muscle wasting. Protein intake should be carefully monitored to meet their nutritional needs while avoiding excessive waste buildup.
C. Increasing fluids is not typically advised for dialysis patients, as they often have fluid restrictions due to reduced kidney function and the risk of fluid overload.
D. Encouraging potassium-rich foods is not advisable for patients with renal disease, particularly if they are on dialysis, as they often have issues with potassium retention, which could lead to dangerous hyperkalemia.
Correct Answer is B
Explanation
A. A blood pressure of 130/90 mm Hg is slightly elevated but not immediately life-threatening and is not typically an urgent triage concern.
B. Respirations of 6 breaths/min indicate severe respiratory distress and inadequate ventilation, which is a critical finding that requires immediate attention. This finding justifies placing the patient in the urgent triage category.
C. Body temperature of 104°F (40°C) may indicate infection or other serious conditions, but it is not as immediately life-threatening as significantly impaired respiratory function.
D. Heart rate of 70 beats/min is normal and does not indicate an urgent need for care.
