1. Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?
- A. Increased pulse
- B. Diarrhea
- C. Constipation
- D. Mydriasis
Correct answer: B
Rationale: Atropine, an anticholinergic drug, commonly causes side effects like increased pulse, mydriasis (dilated pupils), and constipation due to its inhibitory effect on the parasympathetic nervous system. Diarrhea is not typically a side effect of Atropine, making it the correct answer.
2. When educating a client starting Simvastatin, which instruction should the nurse provide?
- A. Take this medication in the evening.
- B. Change positions slowly when rising from a chair.
- C. Maintain a consistent intake of green leafy vegetables.
- D. Limit fluid intake to 1 L per day.
Correct answer: A
Rationale: The correct answer is to take Simvastatin in the evening. This timing is important because the body synthesizes the most cholesterol at night. By taking the medication in the evening, its effectiveness is increased, leading to better outcomes for the client.
3. A hospitalized client has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should be prepared for transfusion?
- A. Whole blood
- B. Platelets
- C. Fresh frozen plasma
- D. Packed red blood cells
Correct answer: C
Rationale: Fresh frozen plasma is the appropriate blood product for a client with an elevated aPTT as it contains various coagulation factors that can help correct coagulopathies and prevent bleeding. Elevated aPTT indicates a deficiency in specific clotting factors, and fresh frozen plasma is rich in these factors. Whole blood, platelets, and packed red blood cells do not contain the necessary coagulation factors to correct an elevated aPTT, so they are not indicated in this situation.
4. A hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?
- A. Vitamin K1
- B. Atropine
- C. Protamine
- D. Calcium gluconate
Correct answer: C
Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.
5. A client is taking metformin for type 2 diabetes. Which of the following findings should indicate to the nurse that the medication is effective?
- A. Increased urine output
- B. Decreased fasting blood glucose
- C. Decreased hemoglobin A1C
- D. Decreased polyuria
Correct answer: C
Rationale: A decrease in hemoglobin A1C is a more specific indicator of metformin's effectiveness in controlling blood glucose levels over a longer period compared to fasting blood glucose levels. Hemoglobin A1C reflects average blood sugar levels over the past 2-3 months, providing a more comprehensive view of glycemic control. Increased urine output (choice A) is not a direct indicator of metformin's effectiveness and can be influenced by various factors. Decreased fasting blood glucose (choice B) can fluctuate due to various reasons and may not provide a reliable long-term assessment of metformin's efficacy. Decreased polyuria (choice D) refers to a symptom rather than a direct measure of metformin's effectiveness in managing diabetes.
