1. 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.
2. A client is being educated by a healthcare provider about Terbutaline. Which of the following statements by the client indicates understanding of the teaching?
- A. This medication will stop my contractions.
- B. This medication will prevent vaginal bleeding.
- C. This medication will promote blood flow to my baby.
- D. This medication will increase my prostaglandin production.
Correct answer: A
Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. It is commonly used to delay preterm labor. Choice B is incorrect because Terbutaline is not used to prevent vaginal bleeding. Choice C is incorrect because Terbutaline's primary action is not related to promoting blood flow to the baby. Choice D is incorrect because Terbutaline does not increase prostaglandin production; instead, it works by blocking beta2-adrenergic receptors.
3. A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?
- A. A headache indicates a serious allergic reaction to nitroglycerin.
- B. The client will not have a headache if the nitroglycerin is taken with a high-fat meal.
- C. Nitroglycerin does not cause a headache.
- D. The most common side effect of nitroglycerin is a headache.
Correct answer: D
Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.
4. When teaching a client with a new prescription for Furosemide, which instruction should the nurse include?
- A. Take this medication at bedtime.
- B. Avoid eating foods high in potassium.
- C. Change positions slowly.
- D. Take this medication with meals.
Correct answer: C
Rationale: The correct instruction for a client with a new prescription for Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these potential adverse effects. Choices A, B, and D are incorrect. Taking Furosemide at bedtime (Choice A) is not necessary as it can be taken at any time of the day. Avoiding foods high in potassium (Choice B) is more relevant for clients taking potassium-sparing diuretics. Taking Furosemide with meals (Choice D) may lead to increased diuretic effects and frequent urination.
5. When teaching a client with schizophrenia strategies to cope with anticholinergic effects of Fluphenazine, which of the following should the nurse suggest to minimize anticholinergic effects?
- A. Take the medication in the morning to prevent insomnia.
- B. Chew sugarless gum to moisten the mouth.
- C. Use cooling measures to decrease fever.
- D. Take an antacid to relieve nausea.
Correct answer: B
Rationale: The correct answer is B: 'Chew sugarless gum to moisten the mouth.' Chewing sugarless gum can help alleviate dry mouth, which is a common anticholinergic effect of Fluphenazine. Dry mouth can be uncomfortable and affect the client's oral health. Options A, C, and D are incorrect because they do not directly address anticholinergic effects. Taking the medication in the morning to prevent insomnia (Option A) is unrelated to anticholinergic effects. Using cooling measures to decrease fever (Option C) is not a common anticholinergic effect of Fluphenazine. Taking an antacid to relieve nausea (Option D) does not specifically target anticholinergic effects.
