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. When teaching a client about a new prescription for Celecoxib, which of the following information should the nurse include?
- A. Increases the risk for a myocardial infarction
- B. Decreases the risk of stroke
- C. Inhibits COX-1
- D. Increases platelet aggregation
Correct answer: A
Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. Celecoxib belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Choice B is incorrect because Celecoxib does not decrease the risk of stroke. Choice C is incorrect because Celecoxib selectively inhibits COX-2 rather than COX-1. Choice D is incorrect because Celecoxib does not increase platelet aggregation; in fact, it inhibits platelet aggregation.
3. A healthcare professional is preparing to administer a dose of Hydromorphone IV to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication over 5 minutes.
- B. Administer a dose of Naloxone prior to giving the Hydromorphone.
- C. Assess the client's blood pressure prior to administration.
- D. Inject the medication into the client's subcutaneous tissue.
Correct answer: A
Rationale: The healthcare professional should administer IV Hydromorphone slowly over 5 minutes to reduce the risk of hypotension and respiratory depression. Rapid administration can lead to adverse effects due to its potency. Choice B is incorrect because Naloxone is used as an antidote for opioid overdose, not routinely administered with Hydromorphone. Choice C is important but not specific to the administration of Hydromorphone. Choice D is incorrect as Hydromorphone is intended for intravenous use, not subcutaneous injection.
4. A client is taking Paroxetine to treat PTSD and reports teeth grinding at night. Which interventions should the nurse implement to manage Bruxism? (Select all that apply.)
- A. Concurrent administration of buspirone.
- B. Administration of a different SSRI.
- C. Use of a mouth guard.
- D. Changing to a different class of antidepressant medication.
Correct answer: A
Rationale: The correct interventions to manage Bruxism associated with Paroxetine use include A: Concurrent administration of buspirone. Buspirone can help alleviate the side effect of Bruxism. Additionally, C: Use of a mouth guard is recommended to prevent oral damage from teeth grinding. B: Administration of a different SSRI is not necessary since the issue is specific to Paroxetine. D: Changing to a different class of antidepressant medication may be considered in severe cases, but the initial step should be to add buspirone to address the Bruxism caused by Paroxetine.
5. A client has a new prescription for Verapamil to treat angina. The nurse should instruct the client to monitor for which of the following adverse effects?
- A. Muscle pain
- B. Dry cough
- C. Peripheral edema
- D. Increased urination
Correct answer: C
Rationale: Verapamil, a calcium channel blocker, can cause peripheral edema due to vasodilation. Clients should monitor for this adverse effect characterized by swelling in the extremities. Muscle pain (choice A) is not a common adverse effect of Verapamil. Dry cough (choice B) is more commonly associated with ACE inhibitors. Increased urination (choice D) is not a typical adverse effect of Verapamil. Therefore, the correct answer is monitoring for peripheral edema.
