1. What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct answer: D
Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.
2. What is the expected pharmacological action of propranolol?
- A. Block stimulation of beta1 receptors
- B. Alter water and electrolyte transport in the large intestine
- C. Block stimulation of beta2 receptors
- D. Both A and C are correct
Correct answer: D
Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.
3. When administering Amitriptyline to a client experiencing cancer pain, for which of the following adverse effects should the nurse monitor?
- A. Decreased appetite
- B. Explosive diarrhea
- C. Decreased pulse rate
- D. Orthostatic hypotension
Correct answer: D
Rationale: The correct answer is 'Orthostatic hypotension.' When administering Amitriptyline, the nurse should monitor for orthostatic hypotension. This condition can occur due to the drug's anticholinergic effects, leading to a sudden drop in blood pressure when standing up. Symptoms may include dizziness, lightheadedness, and an increased risk of falls. Monitoring for signs of orthostatic hypotension is crucial to prevent complications. Choices A, B, and C are incorrect as decreased appetite, explosive diarrhea, and decreased pulse rate are not typically associated with the administration of Amitriptyline.
4. A nurse manager is reviewing the facility's policies for IV therapy with the members of his team. The nurse manager should remind the team that which of the following techniques helps minimize the risk of catheter embolism?
- A. Performing hand hygiene before and after IV insertion
- B. Rotating IV sites at least every 72 hours
- C. Minimizing tourniquet time
- D. Avoiding reinserting the needle into an IV catheter
Correct answer: D
Rationale: To minimize the risk of catheter embolism, it is crucial to avoid reinserting the needle into an IV catheter. This practice can potentially sever the end of the catheter, leading to catheter embolism. Proper insertion techniques, securement, and avoiding unnecessary manipulations of the catheter can help prevent this serious complication.
5. What is the correct definition of drug absorption?
- A. Movement of a drug from the site of administration to various tissues of the body
- B. Describes the absorption, distribution, metabolism, and excretion of drugs
- C. These types of drugs can be taken over the counter
- D. This addresses how various drugs affect different forms of the body
Correct answer: A
Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.
