The nurse is evaluating the following rhythm strip on a client in the telemetry unit. The client is alert and oriented but complains of slight nausea after eating breakfast. What is the nurse's best action?
Perform a 12 lead EKG and request an order for bumetanide 0.5 mg IV
Administer pantoprazole sodium 40 mg by mouth to decrease GI distress
Administer carvedilol 10 mg by mouth and reassess in 30 minutes
Complete the remainder of the assessment and continue to monitor
The Correct Answer is D
A. The 12-lead EKG might be unnecessary right now, especially since the client has no other alarming symptoms. Bumetanide is also not indicated for nausea or tachycardia in this scenario.
B. There is no clear indication that the nausea is related to acid reflux or GI distress that would justify pantoprazole.
C. The tachycardia could be physiological, and treating it with a beta-blocker is unnecessary unless there is a more concerning underlying cause (like heart failure or ischemia). The priority here is not pharmacological intervention but monitoring the client's overall condition.
D. This action allows for appropriate monitoring of the client's condition. Sinus tachycardia may resolve on its own without intervention, and the client doesn't exhibit severe symptoms requiring immediate pharmacologic treatment.

Correct Answer is ["11"]
Explanation
The patient weighs 121 lbs, which is approximately 55 kilograms (121 ÷ 2.2).
Next, multiply the patient's weight in kilograms by the dosage prescribed, which is 20 units/kg. This results in a total dosage of 1100 units (55 kg × 20 units/kg).
The medication is supplied as 25,000 units in 250 mL, so to find out how many mL of medication is needed, set up a proportion: 25,000 units is to 250 mL as 1100 units is to X mL. Solving for X gives you 11 mL (1100 units × 250 mL ÷ 25,000 units).
Therefore, the nurse will administer 11 mL of Heparin to the patient.
Correct Answer is C
Explanation
A. Hypermagnesemia can cause bradycardia and hypotension, but it is less commonly associated with PVCs. This does not align with the lab results provided.
B. Hypocalcemia can cause arrhythmias, but it is not the most likely cause of PVCs in this case, considering other findings.
C. Hypokalemia (low potassium) is a known cause of PVCs. The patient's potassium level is 2.8 mEq/L, which is significantly low and most likely contributing to the PVCs.
D. Although hyperglycemia can affect cardiac function, it is less commonly linked to PVCs compared to electrolyte imbalances, such as hypokalemia.
