If the patient PTT lab level is too long and greater than 80 seconds, the nurse should notify the doctor.
Which doctor’s order should the nurse anticipate?

Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling.However, diuretics may have some side effects, such as loss of potassium, which can affect the heart and require regular blood tests and dietary changes.Diuretics can also cause other electrolyte abnormalities, such as hyponatremia, hypomagnesemia, hypocalcemia, and metabolic alkalosis. Electrolyte disturbances can have serious consequences for the heart function and rhythm, as well as other organs.

Choice A is wrong because fluid retention is the opposite of what diuretics do.

Diuretics reduce fluid retention by increasing urine output and decreasing blood volume.

Choice B is wrong because hypotension is not a direct effect of diuretics on the heart, but rather a consequence of reduced blood volume and vasodilation.

Hypotension can occur with diuretic use, especially if the dose is too high or the patient is dehydrated, but it is not a specific condition caused by diuretics.

Choice C is wrong because hyperglycemia is not related to diuretics or heart failure.

Hyperglycemia is a condition of high blood sugar, which can be caused by diabetes or other factors.

Diuretics do not affect blood sugar levels directly, although some diuretics may interact with diabetes medications and affect their efficacy.

Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the management of hypertension.They work by preventing the hormone norepinephrine from tightening the muscles in the walls of smaller arteries and veins, thus lowering the blood pressure.Some examples of alpha 1 blockers are doxazosin, prazosin, and terazosin.

Choice A is wrong because alpha 3 adrenergic blockers do not exist.There are only two subtypes of alpha receptors: alpha 1 and alpha 2.

Choice B is wrong because alpha 2 adrenergic antagonists are not used for hypertension.They are used for conditions like attention deficit hyperactivity disorder (ADHD) and opioid withdrawal.Alpha 2 antagonists block the negative feedback mechanism of norepinephrine release, thus increasing the amount of norepinephrine in the blood and raising the blood pressure.

Choice C is wrong because alpha 1 adrenergic agonists have the opposite effect of alpha 1 blockers.They stimulate the alpha 1 receptors and cause vasoconstriction, which increases the blood pressure.Alpha 1 agonists are used for conditions like nasal congestion and hypotension.
