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. When teaching a patient to take their own pulse, which medication should the nurse instruct them to monitor? (Hint: if pulse is <60 or >100, the patient should contact their healthcare provider before taking the medication)
- A. Digoxin
- B. Lithium
- C. Montelukast
- D. Phenytoin
Correct answer: A
Rationale: It is essential for patients taking Digoxin to monitor their pulse regularly. If their pulse falls below 60 or exceeds 100 beats per minute, they should contact their healthcare provider immediately. This is crucial due to Digoxin's potential to affect heart rate, making pulse monitoring a vital aspect of patient care while on this medication.
3. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?
- A. Hemoglobin
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.
4. A client has a new prescription for Enfuvirtide to treat HIV infection. The nurse should monitor the client for which of the following adverse reactions?
- A. Bone marrow suppression
- B. Pancreatitis
- C. Pancreatitis
- D. Bone marrow suppression
Correct answer: D
Rationale: While bone marrow suppression is not typically associated with Enfuvirtide, a more relevant concern is the risk of severe allergic reactions such as anaphylaxis. Enfuvirtide, an HIV fusion inhibitor, can cause local injection site reactions and systemic allergic responses. Monitoring for signs of allergic reactions, such as rash, fever, and difficulty breathing, is crucial to ensure the client's safety.
5. A client has a new prescription for erythromycin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should take this medication with a full glass of water.
- B. I should avoid direct sunlight while taking this medication.
- C. I will take this medication on an empty stomach.
- D. I should take an antacid 30 minutes before taking this medication.
Correct answer: C
Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with a full glass of water (Choice A) is incorrect. Avoiding direct sunlight (Choice B) is not related to erythromycin use. Taking an antacid before the medication (Choice D) can interfere with its absorption.
