Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse offers diet teaching to a female college student who was diagnosed with iron-deficiency anemia following her voluntary adoption of a lacto-vegetarian diet. What nutrients should the nurse suggest this client eat to best meet her nutritional needs while allowing her to adhere to a lacto-vegetarian diet?

• A. Drink whole milk instead of skim milk to enhance the body's production of amino acids
• B. Take vitamin K 10mg PO daily to enhance production of red blood cells
• C. Increase amounts of dark yellow vegetables such as carrots to fortify iron stores
• D. Combine several legumes and grains such as beans and rice to form complete proteins

Correct answer: D

Rationale: Combining legumes and grains ensures the client receives all essential amino acids to form complete proteins, which is crucial in a vegetarian diet. Options A, B, and C are incorrect. Option A is not necessary as there are plant-based sources of essential amino acids in a lacto-vegetarian diet. Option B suggests vitamin K, which is not directly related to enhancing red blood cell production. Option C mentions increasing dark yellow vegetables, which are sources of non-heme iron, but combining legumes and grains is more effective in addressing the protein needs of a lacto-vegetarian.

3. The nurse is performing a physical assessment of a male client who has chronic renal failure. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Client reports difficulty breathing
• B. Client reports shortness of breath when lying flat
• C. Client reports swelling in the feet and ankles
• D. Client reports a metallic taste in the mouth

Correct answer: A

Rationale: In a client with chronic renal failure, difficulty breathing is the most critical finding to report. This symptom may indicate fluid overload or pulmonary edema, which can be life-threatening. Shortness of breath when lying flat (orthopnea) is also concerning but less urgent than difficulty breathing. Swelling in the feet and ankles (edema) is a common finding in renal failure but may not be as immediately critical as difficulty breathing. A metallic taste in the mouth is associated with uremia, a common complication of chronic renal failure, but it is not as urgent as respiratory distress.

4. A client who has had three spontaneous abortions is requesting information about possible causes. The nurse's response should be based on which information?

• A. Chromosomal abnormalities are the most common cause of early spontaneous abortions
• B. Incompetent cervix can cause spontaneous abortions
• C. An infection can cause spontaneous abortions
• D. Nutritional deficiencies are the most common cause of early spontaneous abortions

Correct answer: A

Rationale: The correct answer is A: Chromosomal abnormalities are the most common cause of early spontaneous abortions. Spontaneous abortions, also known as miscarriages, often occur due to chromosomal abnormalities in the fetus. These abnormalities are a common cause of early pregnancy loss. Choice B is incorrect because an incompetent cervix typically leads to late miscarriages, not early spontaneous abortions. Choice C is incorrect as while infections can be a cause of spontaneous abortions, they are not the most common cause. Choice D is incorrect as nutritional deficiencies are not the most common cause of early spontaneous abortions.

5. A client with chronic renal failure is being discharged with a prescription for erythropoietin (Epogen). Which statement indicates that the client understands the action of this medication?

• A. It helps my body make red blood cells
• B. It helps prevent infections
• C. It helps my kidneys excrete excess fluid
• D. It helps me breathe easier

Correct answer: A

Rationale: The correct answer is A: 'It helps my body make red blood cells.' Erythropoietin is a medication that stimulates the production of red blood cells in the body. Clients with chronic renal failure often develop anemia due to decreased erythropoietin production by the kidneys. This medication helps address that issue by increasing red blood cell production. Choices B, C, and D are incorrect because erythropoietin does not prevent infections, help kidneys excrete excess fluid, or assist with breathing; its primary action is to boost red blood cell production.
