1. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of citrus fruits.
- D. Avoid high-sodium foods.
Correct answer: A
Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.
2. A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?
- A. Administer regular insulin intravenously.
- B. Give oral hypoglycemic agents.
- C. Administer sodium bicarbonate.
- D. Provide a high-calorie diet.
Correct answer: A
Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Administering oral hypoglycemic agents is not appropriate in the acute setting of DKA as they may not work quickly enough compared to intravenous insulin. While sodium bicarbonate may be used to correct acidosis, insulin administration is the priority to address both hyperglycemia and acidosis simultaneously. Providing a high-calorie diet is not suitable initially in DKA management; the main focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.
3. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?
- A. Refer her for an exploratory laparotomy
- B. Measure serum gastrin in response to secretin infusion
- C. Treat her for H. pylori
- D. Obtain a dedicated small bowel series
Correct answer: B
Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.
4. A client with myelogenous leukemia is receiving an autologous bone marrow transplantation (BMT). What is the priority intervention that the nurse should implement when the bone marrow is repopulating?
- A. Administer sargramostim (Leukine, Prokine).
- B. Infuse PRBC and platelet transfusions.
- C. Give parenteral prophylactic antibiotics.
- D. Maintain a protective isolation environment.
Correct answer: D
Rationale: Maintaining a protective isolation environment is crucial during the repopulation of bone marrow post-transplant to reduce the risk of infections. The client's immune system is compromised during this period, making them highly susceptible to infections. By implementing protective isolation measures, the nurse can help prevent exposure to pathogens, safeguarding the client's health and supporting the success of the transplantation.
5. When implementing patient teaching for a patient admitted with hyperglycemia and newly diagnosed diabetes mellitus scheduled for discharge the second day after admission, what is the priority action for the nurse?
- A. Instruct about the increased risk of cardiovascular disease.
- B. Provide detailed information about dietary glucose control.
- C. Teach glucose self-monitoring and medication administration.
- D. Give information about the effects of exercise on glucose control.
Correct answer: C
Rationale: The priority action for the nurse when time is limited is to focus on essential teaching. In this scenario, the patient should be educated on how to self-monitor glucose levels and administer medications to control glucose levels. This empowers the patient with immediate skills for managing their condition. Instructing about the increased risk of cardiovascular disease (choice A) is important but not as urgent as teaching self-monitoring and medication administration. Providing detailed information about dietary glucose control (choice B) can be beneficial but is secondary to ensuring the patient can monitor and manage their glucose levels. Teaching about the effects of exercise (choice D) is relevant but not as critical as immediate self-monitoring and medication administration education.
