The nurse has provided information to a patient with diabetes who has been prescribed a non-selective beta-adrenergic blocker. Which statement is correct?
I may have low blood sugars.
My dosage may need adjustment if I start taking any NSAIDs.
I will need to be evaluated in a few weeks to see if my dosage is effective.
If I get dizzy, I will stop taking the medication.
The Correct Answer is A
Choice A reason: This is the correct statement. Non-selective beta-adrenergic blockers can interfere with the signs and symptoms of hypoglycemia (low blood sugar), such as tachycardia, tremors, and sweating. They can also impair the glucose metabolism and insulin secretion in the body. Therefore, patients with diabetes who take non-selective beta-adrenergic blockers need to monitor their blood glucose levels closely and adjust their insulin or oral hypoglycemic agents accordingly.
Choice B reason: This is not a correct statement. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, do not interact with non-selective beta-adrenergic blockers. However, they can reduce the effectiveness of other antihypertensive medications, such as diuretics or ACE inhibitors, by causing fluid retention and decreasing renal blood flow.
Choice C reason: This is not a correct statement. Non-selective beta-adrenergic blockers have a rapid onset of action and can lower the blood pressure within hours of administration. Therefore, patients do not need to wait for a few weeks to see if their dosage is effective. However, they may need periodic follow-up visits to monitor their blood pressure, heart rate, and other vital signs.
Choice D reason: This is not a correct statement. Dizziness is a common side effect of non-selective beta-adrenergic blockers, especially when the patient changes position or stands up quickly. This is due to the orthostatic hypotension (a drop in blood pressure when standing up) caused by the vasodilation effect of the medication. However, this does not mean that the patient should stop taking the medication, as this can cause rebound hypertension and other complications. Instead, the patient should rise slowly from a sitting or lying position, drink plenty of fluids, and report any severe or persistent dizziness to their health care provider.

Correct Answer is ["B","C"]
Explanation
Choice A reason: Oliguria is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to reduced renal perfusion and activation of the renin-angiotensin-aldosterone system.
Choice B reason: Increased heart rate is a forward effect of left ventricular heart failure. It is a compensatory mechanism that occurs due to reduced cardiac output and sympathetic stimulation.
Choice C reason: Wet cough is a forward effect of left ventricular heart failure. It is a sign of pulmonary congestion and edema that result from increased pressure in the pulmonary veins and capillaries.
Choice D reason: Confusion is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to reduced cerebral perfusion and hypoxia.
Choice E reason: Jugular venous distention is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to increased pressure in the right atrium and vena cava.
Correct Answer is D
Explanation
Choice A reason: Abnormally dilated arteries and veins are not a result of atherosclerosis. They are a sign of aneurysms or varicose veins, which are caused by different factors.
Choice B reason: Arterial wall thinning and weakening are not a result of atherosclerosis. They are a sign of arteriosclerosis, which is a general term for the loss of elasticity and flexibility of the arteries.
Choice C reason: Autonomic nervous system imbalances are not a result of atherosclerosis. They are a sign of dysautonomia, which is a disorder of the nervous system that affects the regulation of vital functions.
Choice D reason: Abnormal thickening and hardening of vessel walls are a result of atherosclerosis. They are caused by the accumulation of plaque, which is composed of cholesterol, fatty substances, calcium, and other materials.
