Nursing Elites

1. What is the antidote for Heparin?

• A. Protamine sulfate
• B. Narcan
• C. Romazicon
• D. Naloxone

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant medication used to prevent blood clots. In cases of overdose or excessive bleeding due to Heparin, protamine sulfate is administered as the specific antidote. Protamine sulfate works by neutralizing Heparin's anticoagulant activity. Choices B, C, and D are incorrect. Narcan (Naloxone) is used to reverse opioid overdose, Romazicon (Flumazenil) is used to reverse benzodiazepine overdose, and Naloxone is also used to reverse opioid overdose but is not the antidote for Heparin.

2. A client has a new prescription for Captopril. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid foods high in potassium.
• C. Take this medication on an empty stomach.
• D. Increase your intake of sodium-rich foods.

Correct answer: C

Rationale: Captopril should be taken on an empty stomach for better absorption. The client should be instructed to take it 1 hour before or 2 hours after meals to optimize its effectiveness. Taking it with food can reduce its absorption and efficacy.

3. To which pharmacologic classification does the drug propranolol belong?

• A. Beta Blockers
• B. Cholinergics
• C. Immune globulins
• D. Barbiturates

Correct answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

4. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:

• A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
• B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
• C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
• D. To lower blood glucose by stimulating the release of insulin

Correct answer: A

Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.

5. A client is being taught by a healthcare professional about preventing Otitis Externa. Which of the following instructions should the healthcare professional include?

• A. Clean the ear with a cotton-tipped swab daily
• B. Place earplugs in the ears when sleeping at night
• C. Use a cool water irrigation solution to remove earwax
• D. Tip the head to the side to remove water from the ears after showering

Correct answer: D

Rationale: To prevent Otitis Externa, it is important to remove water from the ears after showering or swimming. This helps reduce the risk of moisture buildup in the ear canal, which can lead to infection. Cleaning the ear with a cotton-tipped swab daily can actually increase the risk of injury or infection. Placing earplugs in the ears when sleeping at night may trap moisture and promote bacterial growth. Using a cool water irrigation solution to remove earwax is not recommended as it can disrupt the natural balance of the ear canal.
