1. A patient on a medical-surgical unit administers a hypnotic medication to an older adult client at 2100. The next morning, the client is drowsy and wants to sleep instead of eating breakfast. Which of the following factors should the nurse identify as a possible reason for the client's drowsiness?
- A. Reduced cardiac function
- B. First-pass effect
- C. Reduced hepatic function
- D. Increased gastric motility
Correct answer: C
Rationale: In older adults, reduced hepatic function can lead to prolonged effects of medications metabolized by the liver. This prolonged effect may result in drowsiness the next morning. Adjusting the dosage of the hypnotic medication may be necessary for this client. Choices A, B, and D are incorrect. Reduced cardiac function (Choice A) is not typically associated with drowsiness due to medication effects. The first-pass effect (Choice B) relates to the initial metabolism of a drug in the liver before reaching systemic circulation, which is not directly linked to drowsiness the next morning. Increased gastric motility (Choice D) does not commonly cause drowsiness as described in the scenario.
2. 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.
3. A client with asthma has new prescriptions for cromolyn and albuterol by nebulizer. Which statement by the client indicates an understanding of the teaching?
- A. If my breathing begins to feel tight, I will use the cromolyn immediately.
- B. I will be sure to take the albuterol before taking the cromolyn.
- C. I will use both medications immediately after exercising.
- D. I will administer the medications 10 minutes apart.
Correct answer: B
Rationale: The correct answer is B. Taking albuterol before cromolyn ensures that the airways are open, allowing the cromolyn to reach the lungs effectively. Choice A is incorrect because cromolyn is a preventive medication and should be used regularly, not just when symptoms worsen. Choice C is incorrect because medications should be used as prescribed, not based on a specific event like exercising. Choice D is incorrect because there is no need to wait 10 minutes between administering these two medications when using a nebulizer.
4. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?
- A. Warfarin
- B. Amlodipine
- C. Nitroglycerin
- D. Clopidogrel
Correct answer: A
Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.
5. A client has a new prescription for Propranolol. Which of the following statements should the nurse include in teaching the client?
- A. You may experience a rapid heart rate while taking this medication.
- B. Take the medication with food.
- C. Avoid sudden changes in position.
- D. Increase your intake of high-sodium foods.
Correct answer: C
Rationale: The correct statement to include when teaching a client about Propranolol is to avoid sudden changes in position. Propranolol, a beta-blocker, can lead to dizziness and lightheadedness, particularly when changing positions. Therefore, clients should be advised to change positions slowly to prevent falls and related injuries. Choice A is incorrect because Propranolol actually helps lower heart rate and blood pressure. Choice B is not a specific requirement for taking Propranolol. Choice D is also incorrect as increasing high-sodium foods is not recommended with Propranolol which can affect blood pressure control.
