A nurse is caring for a client who has a life-threatening ventricular dysrhythmia. Which of the following medications should the nurse anticipate administering?
Verapamil
Digoxin
Dopamine
Amiodarone
The Correct Answer is D
A. Verapamil: Verapamil is a calcium channel blocker primarily used to treat supraventricular
tachycardias, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular dysrhythmias.
B. Digoxin: Digoxin is a cardiac glycoside used primarily for atrial fibrillation and heart failure, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular
dysrhythmias.
C. Dopamine: Dopamine is a sympathomimetic medication used for hemodynamic support in hypotension and shock. While it may be used in some cases of unstable bradycardia, it is not the first-line medication for life-threatening ventricular dysrhythmias.
D. Amiodarone: Amiodarone is an antiarrhythmic medication used for the treatment of various ventricular and supraventricular dysrhythmias, including life-threatening ventricular
dysrhythmias such as ventricular tachycardia and ventricular fibrillation. It is often used as a first-line medication for these conditions due to its efficacy and safety profile. Therefore, the nurse should anticipate administering amiodarone for the client's life-threatening ventricular dysrhythmia.

Correct Answer is C
Explanation
A. Prior episode of kidney stones: A history of kidney stones is not a contraindication to prednisone therapy. However, it may require monitoring due to potential fluid and electrolyte imbalances associated with corticosteroid use.
B. Taking levothyroxine orally: Taking levothyroxine orally is not a contraindication to prednisone therapy. However, concurrent use of corticosteroids and levothyroxine may require dosage adjustments of both medications due to potential interactions.
C. Has a systemic fungal infection: Corticosteroids like prednisone can suppress the immune system, increasing the risk of fungal infections and worsening existing fungal infections.
Therefore, the presence of a systemic fungal infection is a contraindication to corticosteroid therapy.
D. History of asthma: Asthma is not a contraindication to prednisone therapy. In fact, prednisone is commonly used as a treatment for asthma exacerbations. However, caution may be needed in individuals with asthma to avoid exacerbating symptoms or complications.
Correct Answer is C
Explanation
A. Hang the TPN solution to gravity to infuse: TPN solutions are typically administered using an infusion pump to control the rate of infusion accurately. Hanging the solution to gravity is not recommended because it may lead to inconsistent flow rates and inaccurate delivery of nutrients.
B. Titrate TPN solution to blood pressure: TPN solutions are not titrated based on blood pressure.
The composition and rate of TPN infusion are typically determined by the client's nutritional needs and metabolic status, not blood pressure.
C. Monitor the client's weight daily: Monitoring the client's weight daily is essential when administering TPN to assess for fluid balance, nutritional status, and response to therapy. Changes in weight can indicate fluid retention, dehydration, or changes in nutritional status, which may require adjustments to the TPN regimen.
D. Obtain the client's blood glucose level weekly: Blood glucose levels should be monitored frequently in clients receiving TPN, as hyperglycemia is a common complication. Weekly monitoring may not be sufficient to detect and manage hyperglycemia promptly. Therefore,
blood glucose levels are typically monitored more frequently, such as multiple times daily or according to institutional protocols.
