1. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Take this medication at bedtime.
- C. Take this medication on an empty stomach.
- D. Take this medication with antacids.
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption. By taking Levothyroxine on an empty stomach, the client ensures optimal absorption and effectiveness of the medication.
2. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
3. What is the pharmacological class of Lithium?
- A. Antidiabetics, biguanides
- B. Mood stabilizers
- C. Antiarrhythmics, anticonvulsants
- D. Vascular headache suppressants
Correct answer: B
Rationale: Lithium is classified as a mood stabilizer due to its primary use in managing bipolar disorder, where it helps stabilize mood swings and prevent episodes of mania and depression. While it can have other effects on the body, its main therapeutic role lies in its mood-stabilizing properties. Choices A, C, and D are incorrect as lithium is not classified as antidiabetics, biguanides, antiarrhythmics, anticonvulsants, or vascular headache suppressants. Its main pharmacological class is mood stabilizers.
4. Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?
- A. To prevent stroke in high-risk patients, such as those with prosthetic heart valves
- B. To decrease blood pressure
- C. To increase heart rate
- D. To provide antiplatelet activity in patients who cannot tolerate aspirin
Correct answer: D
Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.
5. A client is taking Ritonavir, a protease inhibitor, to treat HIV infection. The nurse should monitor for which of the following adverse effects of this medication?
- A. Increased TSH level
- B. Decreased ALT level
- C. Hypoglycemia
- D. Hyperlipidemia
Correct answer: D
Rationale: The correct answer is D: Hyperlipidemia. Ritonavir, a protease inhibitor used in HIV treatment, can lead to hyperlipidemia, characterized by increased cholesterol and triglyceride levels. Monitoring lipid levels is crucial to identify and manage this potential adverse effect. Choices A, B, and C are incorrect because Ritonavir is not known to cause an increased TSH level, decreased ALT level, or hypoglycemia as adverse effects.
