1. A nurse is caring for a client with hypertension who asks about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients with a history of which of the following conditions?

• A. Asthma
• B. Glaucoma
• C. Depression
• D. Migraines

Correct answer: A

Rationale: Corrected Rationale: Propranolol is contraindicated in clients with a history of asthma because it can cause bronchospasms due to its non-selective beta-blocking properties. By blocking beta-2 receptors in the lungs, propranolol can lead to bronchoconstriction, potentially triggering asthma symptoms and exacerbating respiratory issues. Asthma patients should avoid medications like propranolol that can worsen their condition. Choices B, C, and D are incorrect as propranolol is not contraindicated in clients with glaucoma, depression, or migraines. In fact, propranolol is sometimes used in the treatment of migraines and certain types of glaucoma.

2. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

3. 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.

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

• A. Take this medication at bedtime.
• B. Increase your intake of calcium-rich foods.
• C. Brush and floss your teeth regularly.
• D. Avoid eating foods high in potassium.

Correct answer: C

Rationale: The correct answer is C: 'Brush and floss your teeth regularly.' Phenytoin can cause gingival hyperplasia, a condition that leads to overgrowth of gum tissue. Good oral hygiene practices such as regular brushing and flossing can help prevent or minimize this side effect. In contrast, choices A, B, and D are not directly related to managing the side effects of Phenytoin. Taking the medication at bedtime (choice A) is not a specific instruction related to oral hygiene. Increasing calcium-rich foods intake (choice B) may be beneficial for bone health but is not directly related to preventing gingival hyperplasia. Avoiding foods high in potassium (choice D) is not a necessary instruction for a client taking Phenytoin.

5. What is the classification of Ondansetron?

• A. Antihypertensive
• B. Antiarrhythmic
• C. Antiemetic
• D. Antiulcer agent

Correct answer: C

Rationale: Ondansetron is classified as an antiemetic. It is commonly used to prevent nausea and vomiting, especially in patients undergoing chemotherapy or surgery. Choice A, Antihypertensive, is incorrect as Ondansetron is not used to treat high blood pressure. Choice B, Antiarrhythmic, is incorrect as Ondansetron is not used to manage heart rhythm abnormalities. Choice D, Antiulcer agent, is incorrect as Ondansetron is not primarily indicated for treating ulcers.
