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 A
Explanation
A) "I will weigh myself daily and report significant changes in weight":
This statement demonstrates an understanding of the nurse's teaching about diuretics. Diuretics are medications that promote diuresis, leading to increased urine output and fluid loss. Monitoring weight daily can help the client identify fluid retention or volume overload, which are common concerns in individuals taking diuretics. Significant changes in weight, such as sudden increases, may indicate fluid retention or worsening heart failure and should be reported to the healthcare provider promptly for further evaluation.
B) "If my leg gets swollen again, I'll be sure to take an additional pill":
This statement indicates a misunderstanding of the nurse's teaching. Taking an additional pill without healthcare provider guidance can lead to medication overdose and potential adverse effects. It's important for clients to follow the prescribed dosage regimen and consult their healthcare provider before making any changes to their medication regimen.
C) "I will take my medication before bedtime":
While taking diuretics before bedtime may be appropriate for some individuals, it is not a universal recommendation. The timing of diuretic administration can vary depending on the specific type of diuretic prescribed, the client's individual needs, and the presence of any coexisting conditions. Therefore, this statement does not necessarily indicate an understanding of the nurse's teaching about diuretics.
D) "I will have to limit my high sugar foods":
This statement does not directly relate to the nurse's teaching about diuretics. While dietary modifications may be necessary for certain health conditions, such as diabetes, they are not specifically related to the mechanism of action or management of diuretic therapy. Therefore, this statement does not demonstrate an understanding of the nurse's teaching about diuretics.
Correct Answer is ["32"]
Explanation
Find the concentration of heparin in the solution:
Total heparin (units): 25,000 units
Volume of solution (mL): 500 mL
Heparin concentration (units/mL) = Total heparin (units) / Volume of solution (mL)
Heparin concentration (units/mL) = 25,000 units / 500 mL = 50 units/mL
Set up the flow rate equation:
Desired heparin infusion rate (units/hr): 1600 units/hr
Heparin concentration in solution (units/mL): 50 units/mL
Flow rate (mL/hr): We need to solve for this
Flow rate (mL/hr) = Desired heparin infusion rate (units/hr) / Heparin concentration (units/mL)
Calculate the flow rate (mL/hr):
Flow rate (mL/hr) = 1600 units/hr / 50 units/mL = 32 mL/hr (round to nearest whole number as requested)
Therefore, the nurse should set the IV pump to deliver approximately 32 mL/hr.
