Nursing Elites

1. A client in the emergency department has Benzodiazepine toxicity due to an overdose. Which of the following actions is the nurse's priority?

• A. Administer flumazenil.
• B. Identify the client's level of orientation.
• C. Infuse IV fluids.
• D. Prepare the client for gastric lavage.

Correct answer: B

Rationale: In a situation where a client presents with Benzodiazepine toxicity, the priority action for the nurse is to assess the client. By identifying the client's level of orientation, the nurse can gather crucial information about the client's mental status, which is essential for determining the appropriate care and interventions needed. Administering flumazenil is used to reverse the effects of benzodiazepines but should be based on a comprehensive assessment. Infusing IV fluids and preparing for gastric lavage may be necessary interventions but should follow a thorough assessment of the client's condition to ensure proper prioritization of care.

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

• A. Brush and floss your teeth regularly.
• B. Avoid drinking grapefruit juice.
• C. Take this medication with food.
• D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.

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

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect decreased urination within the first few days.
• D. Avoid foods high in potassium.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.

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. Which medication is a beta blocker?

• A. Atenolol (Tenormin)
• B. Verapamil (Calan)
• C. Captopril (Capoten)
• D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.
