While dopamine can be used to treat some types of dysrhythmias, the primary therapeutic goal of a continuous IV infusion of dopamine is not to decrease dysrhythmias but to increase blood flow to vital organs.

An increase in pulse is a possible side effect of dopamine but is not considered a therapeutic effect. The therapeutic goal of dopamine is to improve perfusion, not necessarily to increase heart rate.

Dopamine typically causes vasodilation in lower doses and vasoconstriction in higher doses, which can lead to increased blood pressure, not decreased. It is more likely to raise blood pressure rather than lower it.

Lidocaine does not dissolve blood clots; thrombolytics such as tissue plasminogen activator (tPA) are used for clot dissolution.

Lidocaine does not slow intestinal motility. It is primarily used for managing arrhythmias, not gastrointestinal motility.

Although lidocaine can be used in certain pain management situations, its primary role in this case is to prevent dysrhythmias rather than relieve pain.

Blurred vision is not a common adverse effect of simvastatin. It is important to monitor for other symptoms like muscle pain or weakness when taking this medication.

Orthostatic hypotension is not typically associated with simvastatin use. Statins primarily affect lipid levels and not blood pressure.

Urinary retention is not a known side effect of simvastatin. It is more commonly associated with medications like antihistamines or opioids.

Atropine is used to treat bradycardia, not elevated INR levels. It does not affect the coagulation process.

Epinephrine is used in cases of severe allergic reactions or cardiac arrest but is not used to reverse the effects of warfarin or to manage elevated INR levels.

Protamine is used to reverse the effects of heparin, not warfarin. Since the client is on warfarin, vitamin K is the appropriate treatment.

Captopril can be taken with or without food. However, it is generally recommended to take it on an empty stomach for better absorption.

While it is important to monitor for hypotension, counting the pulse rate is not typically necessary with captopril. The primary focus should be on blood pressure.

Weight gain is not a common side effect of captopril. If a client experiences unexplained weight gain, it should be reported as it could indicate fluid retention or heart failure.

This statement is incorrect because the combination of metoprolol (a beta-blocker) and hydrochlorothiazide (a diuretic) does not eliminate the need for weight management. Lifestyle changes, including diet and exercise, remain important for managing hypertension.

The presence of extra letters in the name of the medication does not necessarily indicate a stronger dose. It refers to the additional drug (hydrochlorothiazide) included in the combination, which has a different mechanism of action than metoprolol alone.

This statement is incorrect. The new combination medication includes an additional diuretic, which may require the client to make changes in their lifestyle, such as monitoring for signs of dehydration or changes in electrolyte levels.

Propranolol is sometimes used to treat migraines as it can reduce the frequency and severity of attacks. It is not contraindicated for clients with a history of migraines.

Propranolol is not contraindicated in clients with glaucoma, although caution may be required as beta-blockers can potentially increase intraocular pressure.

Propranolol is not contraindicated in clients with depression, though it can have mood-related side effects. Depression is not an absolute contraindication, but it should be monitored closely.

Potassium iodide is used in certain conditions such as thyroid disorders or radiation exposure, but it does not impact potassium levels. Administering potassium iodide is not appropriate for a client with elevated potassium levels.

Lisinopril, an ACE inhibitor, can contribute to hyperkalemia in some patients.

Digoxin should be used cautiously with elevated potassium levels because hyperkalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. The nurse should monitor potassium closely before administering digoxin.

Vitamin K is used to reverse the effects of warfarin, not heparin. Heparin's effects can be reversed with protamine sulfate, which is an antidote specifically for heparin.

Acetylcysteine is used to treat acetaminophen overdose and is not effective for reversing the effects of heparin.

Deferasirox is used to treat iron overload, not to reverse heparin’s anticoagulant effects.
