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 should Montelukast be taken?
- A. At least two hours before exercise
- B. Daily in the evening
- C. Two hours before exercise or daily in the evening
- D. None of the above
Correct answer: B
Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.
3. While caring for a client taking Propylthiouracil, for which of the following adverse effects should the nurse monitor?
- A. Bradycardia
- B. Insomnia
- C. Heat intolerance
- D. Weight loss
Correct answer: A
Rationale: When a client is taking Propylthiouracil, the nurse should monitor for bradycardia as it is an adverse effect of this medication. Propylthiouracil can lead to a decrease in heart rate, which is known as bradycardia. Monitoring for this adverse effect is crucial to ensure the client's safety and well-being while on this medication. The other options, such as insomnia, heat intolerance, and weight loss, are not commonly associated adverse effects of Propylthiouracil. Therefore, they are incorrect choices for monitoring while the client is on this medication.
4. At what amount does Acetaminophen stop effectively controlling pain?
- A. Over 1,000 mg
- B. 750 mg
- C. Over 1,500 mg
- D. 150 mg
Correct answer: A
Rationale: Acetaminophen is known to lose its effectiveness in controlling pain beyond a dosage of 1,000 mg. Taking more than 1,000 mg will not provide additional pain relief but can increase the risk of adverse effects. Choice B (750 mg) is incorrect because this amount is within the typical recommended dose range for Acetaminophen. Choice C (Over 1,500 mg) is incorrect as it suggests a higher dose than the point at which Acetaminophen starts to lose its effectiveness. Choice D (150 mg) is too low a dose to effectively control pain for most adults.
5. A client has a new prescription for Zolpidem. Which of the following instructions should the nurse include?
- A. Notify the provider if you plan to become pregnant.
- B. Take the medication 1 hr before you plan to go to sleep.
- C. Allow at least 6 hr for sleep when taking Zolpidem.
- D. To increase the effectiveness of Zolpidem, take it with a bedtime snack.
Correct answer: A
Rationale: Zolpidem is classified under Pregnancy Risk Category C. It is essential for the client to inform the provider if she plans to become pregnant as Zolpidem use during pregnancy may pose risks to the fetus. This precaution allows for appropriate assessment and possible adjustments to the treatment plan to ensure the safety of both the client and the developing baby. Choice B is incorrect because Zolpidem is usually taken immediately before bedtime, not 1 hour before. Choice C is incorrect as Zolpidem is known for its quick onset of action, and the client does not need to allocate a specific amount of time for sleep. Choice D is incorrect as taking Zolpidem with food, especially a bedtime snack, may delay its onset of action.
