1. Reteplase (Retavase) has been ordered for a client diagnosed with an MI. The nurse understands that this drug needs to be administered within which time frame following the onset of symptoms?
- A. 45 minutes to 18 hours
- B. 30 minutes to 12 hours
- C. 90 minutes to 36 hours
- D. 60 minutes to 24 hours
Correct answer: B
Rationale: Reteplase (Retavase) is a thrombolytic medication used in the treatment of myocardial infarction (MI). It is crucial to administer this drug within 30 minutes to 12 hours following the onset of symptoms to achieve optimal therapeutic effects and improve patient outcomes. Administering Reteplase within this time frame helps in restoring blood flow to the affected areas of the heart by dissolving blood clots, reducing myocardial damage, and potentially preventing further complications associated with MI.
2. A client has a new diagnosis of Fibromyalgia. Which of the following medications should the nurse anticipate being prescribed for this client?
- A. Colchicine
- B. Hydroxychloroquine
- C. Auranofin
- D. Duloxetine
Correct answer: D
Rationale: The correct answer is Duloxetine. Duloxetine is commonly used to treat fibromyalgia as a serotonin-norepinephrine reuptake inhibitor. It is also indicated for depression and diabetic peripheral neuropathy. Colchicine, Hydroxychloroquine, and Auranofin are not typically prescribed for fibromyalgia. Colchicine is primarily used to treat gout, Hydroxychloroquine for conditions like malaria and rheumatoid arthritis, and Auranofin for rheumatoid arthritis.
3. What is the action of Metformin?
- A. Decreasing intestinal glucose absorption
- B. Increasing sensitivity to insulin
- C. Decreasing hepatic glucose production
- D. All of the above
Correct answer: D
Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.
4. A client has a new prescription for Valproic Acid. The client should be informed that which of the following laboratory tests need to be completed periodically? (Select all that apply.)
- A. Thrombocyte count.
- B. Hematocrit.
- C. Amylase.
- D. Liver function tests.
Correct answer: A
Rationale: Valproic acid can lead to thrombocytopenia, making it essential to monitor the client's thrombocyte count periodically. Additionally, valproic acid can cause pancreatitis, necessitating the monitoring of amylase levels. Furthermore, valproic acid carries a risk of hepatotoxicity, requiring regular monitoring of liver function tests.
5. What is pharmacodynamics?
- A. The medical reference summarizing standards of drug purity, strength, and directions for synthesis
- B. The drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions
- C. The maximum response that a drug can produce
- D. Movements of the drugs throughout the body
Correct answer: B
Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.
