Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. The nurse is analyzing laboratory values for the assigned clients. Which finding, based on the client's medical history, indicates the need for immediate follow-up?

• A. Client with chronic kidney disease and serum creatinine of 1.6 mg/dL
• B. Client with diabetes mellitus and a glycosylated hemoglobin A1c (HbA1c) of 7.0%
• C. Client with heart failure and a B-type natriuretic peptide (BNP) of 140 pg/mL
• D. Client who is male and has anemia with hemoglobin of 16.5 g/dL and hematocrit of 45%

Correct answer: B

Rationale: An HbA1c of 7.0% in a client with diabetes mellitus indicates poor long-term glucose control, necessitating immediate follow-up. Choice A, chronic kidney disease with a serum creatinine of 1.6 mg/dL, though concerning, does not indicate an immediate need for follow-up. Choice C, heart failure with a BNP of 140 pg/mL, may require monitoring but not immediate follow-up. Choice D, a male client with anemia and normal hemoglobin and hematocrit levels, does not warrant immediate attention based on the provided information.

3. Why may patients with hiatal hernia develop anemia?

• A. Iron absorption is reduced
• B. Gastritis may cause bleeding
• C. Iron stores turn over more quickly
• D. Patients have an aversion to foods that are good sources of iron

Correct answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can occur due to the reflux of stomach acid into the esophagus. This gastritis can lead to gastrointestinal bleeding, resulting in anemia. Choice A is incorrect because iron absorption is not necessarily reduced in hiatal hernia. Choice C is incorrect as iron stores turnover rate is not directly related to the development of anemia in this context. Choice D is incorrect as an aversion to iron-rich foods is not a common reason for anemia in patients with hiatal hernia.

4. A patient with diabetes should be advised to avoid which type of carbohydrate?

• A. Simple carbohydrates
• B. Complex carbohydrates
• C. Fiber-rich carbohydrates
• D. All carbohydrates

Correct answer: A

Rationale: A patient with diabetes should be advised to avoid simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels due to their quick absorption, which can be challenging to manage for individuals with diabetes. Complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes as they are absorbed more slowly, leading to more stable blood glucose levels. Avoiding all carbohydrates is not necessary or recommended, as carbohydrates are an essential source of energy and nutrients in a balanced diet.

5. Which situation(s) are classified as natural disasters?

• A. Blizzards
• B. Blizzards, Volcanic eruptions
• C. Volcanic eruptions
• D. Structural collapse

Correct answer: B

Rationale: Blizzards and volcanic eruptions are classified as natural disasters because they are caused by natural forces beyond human control. In contrast, structural collapses are typically a result of man-made factors, making them not classified as natural disasters. Therefore, the correct answer is B.
