Question 1 of 5
Which of the following pharmacologic classifications does the drug propranolol fall under?
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, specifically by blocking beta receptors. Propranolol, in particular, is a non-selective beta blocker that is commonly used to treat conditions such as hypertension, angina, and arrhythmias. It is also used off-label for anxiety and migraine prevention.
Question 2 of 5
Which of the following is an amide type of local anesthetics:
Correct Answer: B
Rationale: Articaine is an amide type of local anesthetic. Local anesthetics can be classified into two main categories: esters and amides. Articaine belongs to the amide group of local anesthetics, along with lidocaine, bupivacaine, and others. Amide local anesthetics tend to have longer duration of action and are less likely to cause allergic reactions compared to ester local anesthetics. In the given choices, Procaine, Amethocaine, and Benzocaine are ester-type local anesthetics, while Cocaine is a unique example of a local anesthetic with mixed properties.

Question 4 of 5
A patient who has been taking a benzodiazepine as a sleep aid for several months wishes to stop taking the medication. The nurse will suggest that the patient taper the dose gradually to avoid which effect?
Correct Answer: D
Rationale: When a patient has been taking a benzodiazepine for an extended period, abruptly stopping the medication can lead to withdrawal symptoms. These symptoms may include anxiety, irritability, agitation, insomnia, tremors, sweating, and in severe cases, seizures. To avoid these withdrawal effects, the nurse will recommend tapering the dose gradually under medical supervision. This approach allows the body to adjust slowly and reduces the likelihood of experiencing withdrawal symptoms. It is essential to follow a tapering schedule under the guidance of a healthcare provider to ensure a smooth transition off the medication and minimize the risk of withdrawal.
Question 5 of 5
A nurse is providing discharge instructions to a patient who is taking atenolol (Tenormin) to treat hypertension. What would the nurse teach the patient regarding a possible drug-drug interaction?
Correct Answer: C
Rationale: A decreased hypertensive effect can occur if a beta-selective adrenergic blocking agent is used in combination with NSAIDs. If this combination is used, the patient should be monitored closely and dosage adjustments made. Antibiotics, oral contraceptives, and antifungal agents are not known to have a drug-drug interaction. The nurse should educate the patient about potential interactions and advise them to consult their healthcare provider before starting any new medications.
