Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. A client with hypocalcemia is receiving calcium gluconate. What assessment finding requires immediate intervention?

• A. Decreased deep tendon reflexes.
• B. Wheezing and stridor.
• C. Decreased bowel sounds.
• D. Positive Chvostek's sign.

Correct answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.

3. A client receiving chemotherapy for cancer treatment is experiencing nausea and vomiting. What is the nurse's best intervention to manage these symptoms?

• A. Offer frequent, small meals
• B. Administer antiemetics before meals
• C. Encourage the client to eat a high-fat diet
• D. Provide the client with cold, carbonated beverages

Correct answer: B

Rationale: Administering antiemetics before meals is the best intervention to manage nausea and vomiting in clients receiving chemotherapy. This proactive approach helps control symptoms by preventing nausea from occurring, rather than waiting to treat it once symptoms have already started. Offering frequent, small meals (choice A) may worsen symptoms in some cases due to increased stomach activity. Encouraging a high-fat diet (choice C) can be difficult for nauseated clients and may not alleviate symptoms. Providing cold, carbonated beverages (choice D) could exacerbate nausea further due to the temperature and carbonation.

4. A client with chronic kidney disease is receiving erythropoietin injections. What laboratory value should the nurse monitor to evaluate the effectiveness of the treatment?

• A. Serum potassium
• B. Hemoglobin
• C. White blood cell count
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Hemoglobin. Erythropoietin stimulates the production of red blood cells, leading to an increase in hemoglobin levels. Monitoring hemoglobin is crucial to assess the effectiveness of the treatment. Choices A, C, and D are incorrect. Serum potassium levels are often monitored in chronic kidney disease, but it is not the primary parameter to evaluate the effectiveness of erythropoietin therapy. White blood cell count and platelet count are not directly influenced by erythropoietin injections for chronic kidney disease.

5. A 48-year-old client with chronic alcoholism is admitted to the hospital. The nurse would anticipate that the client may be deficient in which vitamins?

• A. Vitamin B and vitamin C
• B. Vitamin D and vitamin E
• C. Vitamin K and vitamin A
• D. Vitamin A and vitamin E

Correct answer: A

Rationale: The correct answer is A. Chronic alcoholism commonly leads to deficiencies in B vitamins, particularly thiamine, and vitamin C. Thiamine deficiency can result in serious neurological issues like Wernicke-Korsakoff syndrome, while vitamin C deficiency can lead to scurvy. Choices B, C, and D are incorrect because vitamin D and E deficiencies are not typically associated with chronic alcoholism.
