1. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
2. A client is starting therapy with topotecan. Which of the following findings should the nurse instruct the client to report?
- A. Hair loss
- B. Fatigue
- C. Sore throat
- D. Red urine
Correct answer: C
Rationale: The nurse should instruct the client to report a sore throat because it can indicate an infection due to the immunosuppressive effects of topotecan. Monitoring for signs of infection is crucial to prevent complications during therapy. Choices A, B, and D are less critical findings compared to a sore throat. Hair loss is a common side effect of chemotherapy, fatigue is expected with cancer treatment, and red urine is a known harmless effect of topotecan.
3. A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
- A. Monitor for signs of bleeding.
- B. Avoid taking the medication with food.
- C. Expect to have increased urination.
- D. Take the medication with an antacid.
Correct answer: A
Rationale: Corrected Rationale: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. The client should monitor for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stool, and report them promptly to their healthcare provider for further evaluation and management. Choice B is incorrect because Clopidogrel can be taken with or without food. Choice C is incorrect as increased urination is not a common side effect of Clopidogrel. Choice D is incorrect as taking Clopidogrel with an antacid may reduce its effectiveness.
4. What are the actions of the drug metformin?
- A. Decreases hepatic glucose production and intestinal glucose absorption
- B. Increases sensitivity to insulin
- C. Short-term sedation
- D. Both A and B
Correct answer: D
Rationale: Metformin has dual actions by decreasing hepatic glucose production and intestinal glucose absorption, which helps in reducing blood glucose levels. Additionally, it increases sensitivity to insulin, aiding in its proper utilization within the body. Choice A is correct as metformin acts by decreasing hepatic glucose production and intestinal glucose absorption. Choice B is also correct as metformin increases sensitivity to insulin. Choice C, short-term sedation, is incorrect as metformin is not known for causing sedation. Therefore, the correct answer is D because metformin performs both of these actions.
5. A client with Addison's disease is being admitted for a total hip arthroplasty. The client takes hydrocortisone for Addison's disease. What is the nurse's priority action?
- A. Administering a supplemental dose of hydrocortisone
- B. Instructing the client about coughing and deep breathing
- C. Collecting additional information from the client about his history of Addison's disease
- D. Inserting an indwelling urinary catheter
Correct answer: A
Rationale: The nurse's priority in this situation is to administer a supplemental dose of hydrocortisone. Clients with Addison's disease taking hydrocortisone are at risk of acute adrenal insufficiency during times of stress such as surgery. Administering supplemental doses of hydrocortisone helps prevent acute adrenal insufficiency (adrenal crisis) in these situations, making it the priority action to ensure the client's safety. Instructing the client about coughing and deep breathing is important postoperatively but not the priority at this time. Collecting additional information about the client's history of Addison's disease is important but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority in this situation.
