1. Which drug is the antidote for Alprazolam?
- A. Physostigmine
- B. Protamine sulfate
- C. Flumazenil
- D. Acetylcysteine
Correct answer: C
Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.
2. What is the pharmacological action of metformin?
- A. Blocks stimulation of beta1 and beta2.
- B. Blocks vasoconstriction and aldosterone.
- C. Acts at many levels in the CNS to produce an anxiolytic effect.
- D. Decreases hepatic glucose production.
Correct answer: D
Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
3. A client is taking Propylthiouracil. For which of the following adverse effects of this medication should the nurse monitor?
- A. Bradycardia
- B. Insomnia
- C. Heat intolerance
- D. Weight loss
Correct answer: A
Rationale: Propylthiouracil is a medication used to treat hyperthyroidism. One of the adverse effects of Propylthiouracil is bradycardia, which is a slower than normal heart rate. Since the medication works by decreasing thyroid hormone production, it can lead to hypothyroidism as a side effect, causing bradycardia. Therefore, the nurse should monitor the client for signs and symptoms of bradycardia while taking Propylthiouracil. Choices B, C, and D are incorrect because insomnia, heat intolerance, and weight loss are not typically associated adverse effects of Propylthiouracil.
4. When teaching a client with a prescription for long-term use of oral prednisone for chronic asthma, the nurse should instruct the client to monitor for which of the following adverse effects of this medication?
- A. Weight gain
- B. Nervousness
- C. Bradycardia
- D. Constipation
Correct answer: A
Rationale: The correct answer is weight gain. Weight gain and fluid retention are common adverse effects of oral prednisone due to sodium and water retention. Patients on long-term prednisone therapy should be advised to monitor their weight closely and report any significant changes to their healthcare provider. Choice B, 'Nervousness,' is not typically associated with oral prednisone use. Choice C, 'Bradycardia,' refers to a slow heart rate, which is not a common adverse effect of prednisone. Choice D, 'Constipation,' is not a typical adverse effect of oral prednisone; instead, gastrointestinal disturbances like increased appetite or even peptic ulcer disease may occur.
5. A client with Graves' disease is being educated by a nurse about her prescribed medications. Which of the following statements by the client indicates an understanding of the use of Propranolol in the treatment of Graves' disease?
- A. Propranolol helps increase blood flow to my thyroid gland.
- B. Propranolol is used to prevent excess glucose in my blood.
- C. Propranolol will decrease my tremors and fast heartbeat.
- D. Propranolol promotes a decrease of thyroid hormone in my body.
Correct answer: C
Rationale: The correct answer is C. Propranolol is a beta-adrenergic antagonist that is commonly used in Graves' disease to decrease symptoms such as tremors and fast heart rate. Choice A is incorrect because Propranolol does not increase blood flow to the thyroid gland. Choice B is incorrect as Propranolol is not used to prevent excess glucose in the blood. Choice D is also incorrect as Propranolol does not directly decrease thyroid hormone levels in the body.
