Nursing Elites

1. Which of the following is the antidote for lead poisoning?

• A. Naloxone
• B. Nitrite
• C. CaEDTA
• D. Dialysis

Correct answer: C

Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.

2. What is the expected outcome of Valproate therapy?

• A. Decreased fever
• B. Decreased sense of anxiety
• C. Decreased blood pressure
• D. Decreased seizure activity

Correct answer: D

Rationale: The correct answer is D: Decreased seizure activity. Valproate is commonly used in the treatment of epilepsy to help control and reduce seizure frequency. Choices A, B, and C are incorrect because Valproate is not primarily used to treat fever, anxiety, or blood pressure issues.

3. A client has a prescription for Nitroglycerin. Which of the following instructions should the nurse include?

• A. Take one tablet every 15 minutes until pain is relieved.
• B. Take one tablet every 5 minutes, up to three doses.
• C. Take one tablet at bedtime.
• D. Take one tablet on an empty stomach.

Correct answer: B

Rationale: The correct administration of Nitroglycerin involves taking one tablet at the onset of chest pain, then another tablet every 5 minutes for up to three doses. This protocol aims to relieve angina symptoms. Choice A is incorrect because waiting 15 minutes between doses may delay symptom relief. Choice C is incorrect as Nitroglycerin is not typically taken at bedtime but rather during angina episodes. Choice D is incorrect because Nitroglycerin is usually taken sublingually, so it doesn't need to be taken on an empty stomach.

4. 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.

5. What is the classification of furosemide?

• A. Loop diuretic
• B. Anticoagulant
• C. Iron supplement
• D. Anticonvulsant

Correct answer: A

Rationale: Furosemide is classified as a loop diuretic, not an anticoagulant, iron supplement, or anticonvulsant. Loop diuretics, like furosemide, act in the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine output. This mechanism makes them effective in treating conditions such as edema and hypertension. Therefore, the correct classification for furosemide is a loop diuretic (Choice A).
