1. A drug ending in the suffix (tidine) is considered a ______.

A. Antidepressant
B. Protease inhibitor
C. Beta antagonist
D. H antagonist

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.

2. A client has a new prescription for Albuterol and Beclomethasone inhalers for the control of asthma. Which of the following instructions should the nurse include in the teaching?

A. Take the albuterol at the same time each day.
B. Administer the albuterol inhaler before using the beclomethasone inhaler.
C. Use beclomethasone if experiencing an acute episode.
D. Avoid shaking the beclomethasone before use.

Correct answer: B

Rationale: When a client is prescribed an inhaled beta2-agonist (such as albuterol) and an inhaled glucocorticoid (such as beclomethasone) for asthma control, the beta2-agonist should be administered first. Administering the beta2-agonist before the glucocorticoid helps promote bronchodilation and enhances the absorption of the glucocorticoid, maximizing its effectiveness in the lungs. Choice A is incorrect because albuterol is usually taken as needed for quick relief of asthma symptoms and not necessarily at the same time each day. Choice C is incorrect as beclomethasone is a controller medication used for long-term asthma management, not for acute episodes. Choice D is incorrect as shaking the beclomethasone inhaler before use helps ensure proper medication dispersion for effective inhalation.

3. A client has a new prescription for Metformin to treat type 2 diabetes. Which of the following laboratory results should be monitored?

A. Hemoglobin A1C
B. Liver function tests
C. Electrolyte levels
D. Kidney function

Correct answer: D

Rationale: Metformin is excreted by the kidneys, and impaired kidney function can lead to an increased risk of lactic acidosis, a serious side effect. Therefore, it is important to monitor kidney function regularly while a client is on Metformin. Hemoglobin A1C is used to monitor long-term glucose control, but kidney function is the priority for monitoring Metformin therapy.

4. What is the antidote for copper toxicity?

A. Glucagon
B. Aminocaproic acid
C. Atropine
D. Penicillamine

Correct answer: D

Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.

5. A client is receiving treatment with etoposide. Which of the following findings should the nurse monitor?

A. Hypotension
B. Hyperkalemia
C. Hyperglycemia
D. Hypertension

Correct answer: A

Rationale: Etoposide, a chemotherapeutic agent, commonly causes hypotension as an adverse effect. It is crucial for the nurse to monitor the client for signs of hypotension, such as dizziness, lightheadedness, or a drop in blood pressure, to promptly intervene and prevent complications.
