1. After returning the client to bed following a cardiac catheterization procedure with the left femoral vessel as the access site, the nurse places a sign above the bed instructing the client to remain on bed rest and in which position?
- A. In semi-Fowler's position
- B. With the head of the bed elevated 45 degrees
- C. With the head of the bed elevated no more than 15 degrees
- D. With the foot of the bed elevated as much as tolerated by the client
Correct answer: C
Rationale: After cardiac catheterization via the femoral vessel, it is crucial to keep the head of the bed elevated no more than 15 degrees to prevent bleeding at the access site. This position helps maintain pressure on the femoral artery, reducing the risk of bleeding and complications post-procedure. Choices A, B, and D are incorrect because they do not provide the necessary pressure on the femoral artery to prevent bleeding, which is essential after a cardiac catheterization procedure with a femoral access site.
2. The client is receiving intravenous heparin for the treatment of a pulmonary embolism. Which medication should the nurse ensure is readily available?
- A. Protamine sulfate
- B. Vitamin K
- C. Calcium gluconate
- D. Magnesium sulfate
Correct answer: A
Rationale: Protamine sulfate is the antidote for heparin, used to reverse its anticoagulant effects. It should be readily available in case of bleeding complications, as it can rapidly neutralize the effects of heparin and prevent excessive bleeding. Vitamin K is used to reverse the effects of warfarin, not heparin (Choice B). Calcium gluconate is used to treat calcium deficiencies, not indicated for heparin therapy (Choice C). Magnesium sulfate is used for conditions like preeclampsia and eclampsia, not for reversing heparin effects (Choice D).
3. A client is admitted to the hospital with a venous stasis leg ulcer. The nurse inspects the ulcer expecting to note which observation?
- A. The ulcer has a pale-colored base.
- B. The ulcer is deep, with even edges.
- C. The ulcer has little granulation tissue.
- D. The ulcer has a brownish or 'brawny' appearance.
Correct answer: D
Rationale: When assessing a venous stasis leg ulcer, the nurse should expect to note a brownish or 'brawny' appearance. This discoloration is often due to hemosiderin deposits. The correct answer is not A because venous stasis ulcers typically do not have a pale-colored base. Choice B is incorrect as venous stasis ulcers usually have irregular, shallow edges, not deep and even edges. Choice C is incorrect as venous stasis ulcers often have excess granulation tissue, not little granulation tissue. Recognizing the brownish or 'brawny' appearance is crucial for accurate diagnosis and appropriate treatment of venous stasis leg ulcers.
4. A client diagnosed with angina pectoris returns to the nursing unit after experiencing an angioplasty. The nurse reinforces instructions to the client regarding the procedure and home care measures. Which statement by the client indicates an understanding of the instructions?
- A. I am considering cutting my workload.
- B. I need to cut down on cigarette smoking.
- C. I am so relieved that my heart is repaired.
- D. I need to adhere to my dietary restrictions.
Correct answer: B
Rationale: The correct answer is B because cutting down on cigarette smoking is crucial for improving heart health after angioplasty. Smoking cessation helps in reducing the risk of complications and promotes better outcomes. Choices A and C are not directly related to post-angioplasty care. While reducing workload may be beneficial, it is not specifically related to the client's cardiac health. Feeling relieved that the heart is repaired is a positive emotional response but does not reflect understanding of the necessary measures. Adhering to dietary restrictions is important, but in this scenario, smoking cessation takes higher priority due to its immediate impact on heart health.
5. The client with myocardial infarction should reduce intake of saturated fat and cholesterol. Which food items from the dietary menu would assist the nurse in helping the client comply with diet therapy?
- A. Cheeseburger, pan-fried potatoes, whole kernel corn, sherbet
- B. Pork chop, baked potato, cauliflower in cheese sauce, ice cream
- C. Baked haddock, steamed broccoli, herbed rice, sliced strawberries
- D. Spaghetti and sweet sausage in tomato sauce, vanilla pudding (with 4% milk)
Correct answer: C
Rationale: Option C, which includes baked haddock, steamed broccoli, herbed rice, and sliced strawberries, is the most appropriate choice for a client with myocardial infarction looking to reduce saturated fat and cholesterol intake. This meal is low in saturated fats and cholesterol, making it a heart-healthy option that aligns with the dietary recommendations for such clients. Choices A, B, and D contain foods high in saturated fats and cholesterol, which are not suitable for a client with myocardial infarction trying to adhere to a diet therapy aimed at reducing these components.
