The client has been ordered a nonselective beta-blocking agent called propranolol, PO. Propranolol is used in the treatment of which disorders (Select All that Apply.)
Hypoglycemia
Arrhythmias
Hypertension
Hypokalemia
Angina
Correct Answer : B,C,E
A) Hypoglycemia:
Propranolol, a nonselective beta-blocking agent, can mask some of the symptoms of hypoglycemia, such as tachycardia and tremors, by blocking the sympathetic response. Therefore, it is not typically used in the treatment of hypoglycemia and may even exacerbate low blood sugar levels.
B) Arrhythmias:
Propranolol is commonly used in the treatment of various cardiac arrhythmias. By blocking beta-adrenergic receptors in the heart, it reduces the heart rate and myocardial contractility, thereby helping to control arrhythmias such as atrial fibrillation and ventricular tachycardia.
C) Hypertension:
Propranolol is effective in lowering blood pressure and is often prescribed for the management of hypertension. Its beta-blocking action reduces cardiac output and suppresses renin release, leading to decreased systemic vascular resistance and blood pressure.
D) Hypokalemia:
Propranolol does not have a direct role in the treatment of hypokalemia. While it can potentially exacerbate hypokalemia through its effects on potassium metabolism, it is not a primary treatment for this electrolyte imbalance.
E) Angina:
Propranolol is indicated for the treatment of angina pectoris, particularly in cases of stable angina. By reducing myocardial oxygen demand through its negative chronotropic and inotropic effects, it helps relieve anginal symptoms and improve exercise tolerance."

Correct Answer is ["675"]
Explanation
1. Convert client weight from pounds to kilograms (kg):
We know 1 kg = 2.205 pounds.
Client weight (kg) = 198 lb / 2.205 lb/kg = 90 kg (round to nearest whole number for this calculation).
2. Calculate the total daily dosage:
Prescribed dosage per kg per day: 15 mg/kg/day
Client weight (kg): 90 kg (rounded value from step 1)
Total daily dosage (mg): Dosage (mg/kg/day) x Client weight (kg)
Total daily dosage (mg): 15 mg/kg/day x 90 kg = 1350 mg/day
3. Since the dosage is divided equally every 12 hours, calculate the amount per dose:
Frequency of administration: Every 12 hours
Total daily dosage (mg): 1350 mg/day
Dosage per dose (mg) = Total daily dosage (mg) / Frequency (doses/day)
Dosage per dose (mg) = 1350 mg/day / 2 doses/day
Dosage per dose (mg) = 675 mg/dose (round to nearest whole number as requested)
Therefore, the nurse should administer approximately 675 mg of vancomycin with each dose.
Correct Answer is ["100"]
Explanation
We are given the following information:
Medication: Ticarcillin/clavulanate 3.1 g
Administration route: Intermittent IV bolus over 30 minutes
Available solution: Ticarcillin/clavulanate 3.1 g in 50 mL 0.9% sodium chloride (NSS)
However, the IV pump controls the rate of delivery over time (usually in hours). An intermittent bolus means the medication is infused all at once over a shorter period (30 minutes in this case).
The pump rate calculation here focuses on the total volume of the available solution containing the medication to be delivered, not necessarily on the medication amount itself.
Therefore, we need to find the rate at which the total volume of 50 mL solution should be delivered over 30 minutes.
Conversion is necessary because pump rates are typically set in hours (hr).
Time (hours) = 30 minutes / 60 minutes/hour = 0.5 hours
Now, calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)
Flow rate (mL/hr) = 50 mL / 0.5 hours = 100 mL/hr
Round to the nearest whole number as requested.
Therefore, the nurse should set the pump to deliver approximately 100 mL/hr. This ensures the total 50 mL solution containing the 3.1 g of ticarcillin/clavulanate is delivered over the intended 30-minute period.
