The nurse provides patient teaching for a patient who has a new order for nadolol (Corgard) to treat hypertension. What statement by the patient concerning nadolol (Corgard) would indicate that the teaching has been effective?

Correct Answer: C

Rationale: A patient receiving an adrenergic blocker must be aware that abruptly stopping the medication may result in a serious reaction. When changing medications or discontinuing their use, these drugs need to be tapered off gradually. This drug is not associated with photophobia or the anticholinergic effect of dry mouth. If the teaching were effective, the patient would be aware that he would need to continue lifestyle modifications, including diet and exercise.

Correct Answer: A

Rationale: Ondansetron, which is commonly used to prevent nausea and vomiting, can be administered via three routes: Orally (PO), Intravenously (IV), and Rectally (Rectal). These routes allow for flexible administration based on the patient's condition and needs. Intramuscular (IM) administration is not a recognized route for ondansetron administration.

Correct Answer: D

Rationale: Heparin is an anticoagulant medication that can lead to excessive bleeding if overdosed. Protamine sulfate is the specific antidote for heparin overdose. It works by binding to heparin and neutralizing its anticoagulant effects. This helps to reverse the effects of heparin and prevent further bleeding complications. In cases of heparin overdose or when rapid reversal of heparin's anticoagulant effects is required, protamine sulfate should be administered. Naloxone is used as an antidote for opioid overdose, Ibutilide is a antiarrhythmic medication used for atrial fibrillation, and Methylphenidate is a stimulant medication used for ADHD.

Correct Answer: C

Rationale: Mast cell stabilizers prevent histamine release . Decongestants relieve, not prevent. C offers proactive prevention, making it key.

Correct Answer: D

Rationale: Spironolactone is a potassium-sparing diuretic that works by blocking the reabsorption of sodium and water in the kidneys while retaining potassium. This mechanism can lead to an increased risk of hyperkalemia, a condition characterized by high levels of potassium in the blood. Therefore, patients taking spironolactone should be closely monitored for signs and symptoms of hyperkalemia, such as muscle weakness, fatigue, and abnormal heart rhythms. In contrast, diuretics like hydrochlorothiazide (choice A), furosemide (choice B), and acetazolamide (choice C) are not typically associated with the risk of hyperkalemia.
