1. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?

• A. Heparin
• B. Alprazolam
• C. Digoxin
• D. Levothyroxine

Correct answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

2. 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.

3. When a client is starting long-term oral prednisone for chronic asthma, what adverse effect should the nurse instruct the client to monitor for?

• A. Weight gain
• B. Nervousness
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: Weight gain is a common adverse effect of oral prednisone due to sodium and water retention, which can lead to fluid retention. Monitoring weight changes is important as it helps in early identification of this adverse effect, enabling timely interventions to manage it. Choice B, nervousness, is not typically associated with oral prednisone use. Bradycardia (Choice C) is unlikely as prednisone usually causes tachycardia or increased heart rate. Constipation (Choice D) is not a common adverse effect of prednisone compared to weight gain.

4. A client has a new prescription for Levothyroxine to treat hypothyroidism. Which of the following instructions should be included in the teaching?

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Expect to see results in 1 week.
• D. Do not discontinue the medication without consulting the provider.

Correct answer: D

Rationale: The correct instruction for a client with a new prescription for Levothyroxine to treat hypothyroidism is not to discontinue the medication without consulting the provider. Abrupt cessation could lead to the return of hypothyroid symptoms, emphasizing the importance of medical guidance when considering any changes to the treatment plan. Choice A is incorrect because Levothyroxine should be taken on an empty stomach, typically in the morning. Choice B is incorrect as it contradicts the timing of administration for Levothyroxine. Choice C is inaccurate as it usually takes a few weeks for the full effects of Levothyroxine to be seen, not just 1 week.

5. When teaching a client how to use nitroglycerin transdermal ointment for angina, which instruction should the nurse include?

• A. Remove the prior dose before applying a new dose.
• B. Rub the ointment directly into your skin until it is no longer visible.
• C. Cover the applied ointment with a clean gauze pad.
• D. Apply the ointment to the same skin area each time.

Correct answer: A

Rationale: The correct instruction is to remove the prior dose before applying a new dose. This helps prevent toxicity by ensuring the client does not inadvertently apply an excessive amount of nitroglycerin.
