1. When teaching a client with a new prescription for Clopidogrel, which laboratory value should the nurse monitor to assess for potential adverse effects?
- A. White blood cell count
- B. Platelet count
- C. Hemoglobin
- D. Blood glucose
Correct answer: B
Rationale: Clopidogrel is an antiplatelet medication that works by reducing the formation of blood clots. Therefore, the nurse should monitor the client's platelet count to assess for potential bleeding complications. A decrease in platelet count could indicate a risk of bleeding, which is an adverse effect associated with Clopidogrel therapy. Monitoring other laboratory values like white blood cell count, hemoglobin, and blood glucose is important for assessing overall health status but is not directly related to the potential adverse effects of Clopidogrel.
2. When educating a client with a new prescription for Amlodipine, which instruction should the nurse provide?
- A. Increase your intake of dairy products.
- B. Avoid driving until you see how the medication affects you.
- C. Stop taking the medication if you develop a dry cough.
- D. Take the medication at bedtime.
Correct answer: B
Rationale: The correct answer is to advise the client to avoid driving until they understand the medication's effects. Amlodipine can cause dizziness, making it unsafe to drive until the client knows how the medication affects them. This instruction promotes client safety and prevents potential accidents due to medication side effects.
3. What does it mean when a medication has a half-life?
- A. It only lasts for 30 minutes after the medication is given
- B. How long it takes for half of the dose to be eliminated from the bloodstream
- C. It is the peak of how effective the medicine is
- D. Drug is greatly reduced before it reaches the systemic circulation
Correct answer: B
Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.
4. When teaching a client with a prescription for Phenytoin, which of the following instructions should the nurse include?
- A. Expect the development of a mild rash.
- B. Take the medication on an empty stomach.
- C. Monitor for signs of gingival hyperplasia.
- D. Increase your intake of calcium.
Correct answer: C
Rationale: Phenytoin is known to cause gingival hyperplasia, a condition characterized by overgrowth of gum tissue. The nurse should instruct the client to monitor for signs of gingival hyperplasia, such as swollen or bleeding gums. Good oral hygiene practices are essential to prevent or manage this side effect. Choices A, B, and D are incorrect. Phenytoin does not typically cause a mild rash, should be taken with food to reduce gastrointestinal upset, and does not warrant an increase in calcium intake.
5. Which of the following is the antidote for lead poisoning?
- A. Naloxone
- B. Nitrite
- C. CaEDTA
- D. Dialysis
Correct answer: C
Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.
