ATI Pharmacology Proctored Exam 2023 Quizlet
1. A nurse is caring for a client with hypertension who asks about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients with a history of which of the following conditions?
- A. Asthma
- B. Glaucoma
- C. Depression
- D. Migraines
Correct answer: A
Rationale: Corrected Rationale: Propranolol is contraindicated in clients with a history of asthma because it can cause bronchospasms due to its non-selective beta-blocking properties. By blocking beta-2 receptors in the lungs, propranolol can lead to bronchoconstriction, potentially triggering asthma symptoms and exacerbating respiratory issues. Asthma patients should avoid medications like propranolol that can worsen their condition. Choices B, C, and D are incorrect as propranolol is not contraindicated in clients with glaucoma, depression, or migraines. In fact, propranolol is sometimes used in the treatment of migraines and certain types of glaucoma.
2. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take?
- A. Monitor the client's respiratory rate every 15 minutes.
- B. Monitor the client's blood pressure every 30 minutes.
- C. Monitor the client's oxygen saturation every hour.
- D. Monitor the client's heart rate every 5 minutes.
Correct answer: A
Rationale: The correct action for the nurse is to monitor the client's respiratory rate every 15 minutes while on Morphine IV to promptly detect respiratory depression, a critical adverse effect associated with this medication. Respiratory depression is a common side effect of opioid medications like Morphine and can be life-threatening. Monitoring the respiratory rate frequently enables the nurse to identify early signs of respiratory compromise and intervene promptly. Monitoring other vital signs like blood pressure, oxygen saturation, or heart rate is important but not as crucial as monitoring respiratory rate when a client is on Morphine IV.
3. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?
- A. Vitamin K
- B. Calcium carbonate
- C. Acetaminophen
- D. Ranitidine
Correct answer: C
Rationale: The correct answer is Acetaminophen (Choice C). Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking Warfarin. It can potentiate the anticoagulant effect of Warfarin, leading to an increased risk of bleeding. Vitamin K (Choice A) is actually used to reverse the effects of Warfarin in case of over-anticoagulation, so it does not increase the risk of bleeding. Calcium carbonate (Choice B) and Ranitidine (Choice D) do not significantly interact with Warfarin to increase the risk of bleeding.
4. A healthcare provider is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?
- A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
- B. Obtain help from another healthcare provider to confirm the correct client and blood product.
- C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
- D. Stay with the client for the first 15 to 30 minutes of the transfusion.
Correct answer: B
Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction. Choices A, C, and D are important aspects of transfusion safety but are not directly related to preventing acute hemolytic reactions. Ensuring a patent IV line, monitoring vital signs, and staying with the client are all essential during transfusion but do not specifically address the risk of ABO or Rh incompatibility reactions.
5. 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.
