Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A healthcare professional is preparing to administer a dose of potassium chloride. Which of the following should the professional do?

• A. Administer it as a bolus
• B. Dilute the medication
• C. Give it rapidly
• D. Monitor respiratory rate

Correct answer: B

Rationale: Correct Answer: Dilute the medication. Potassium chloride should always be diluted before administration to avoid irritation and complications. Choice A is incorrect because administering it as a bolus can lead to adverse effects. Choice C is incorrect as giving it rapidly can be dangerous. Choice D is incorrect as monitoring the respiratory rate is not directly related to administering potassium chloride.

3. A nurse is reviewing the laboratory results for a client who has a prescription for filgrastim. The nurse should recognize that an increase in which of the following values indicates a therapeutic effect of this medication?

• A. Erythrocyte count
• B. Neutrophil count
• C. Lymphocyte count
• D. Thrombocyte count

Correct answer: B

Rationale: Filgrastim is used to increase neutrophil production in clients undergoing chemotherapy or with bone marrow suppression. A rise in neutrophil count indicates the medication is working effectively to boost immune response. Choices A, C, and D are incorrect as filgrastim primarily targets neutrophils, not erythrocytes, lymphocytes, or thrombocytes.

4. A client is taking levothyroxine. Which of the following findings should indicate that the medication is effective?

• A. Weight loss
• B. Decreased blood pressure
• C. Absence of seizures
• D. Decreased inflammation

Correct answer: A

Rationale: The correct answer is A: Weight loss. Levothyroxine is used to treat hypothyroidism, which is characterized by symptoms such as weight gain. Therefore, weight loss in a client taking levothyroxine indicates that the medication is effective in managing hypothyroidism. Choices B, C, and D are incorrect because levothyroxine primarily affects thyroid function and metabolism, not blood pressure, seizures, or inflammation.

5. A client is receiving digoxin therapy. Which of the following should the nurse monitor?

• A. Liver function
• B. Serum electrolytes
• C. Blood pressure
• D. All of the above

Correct answer: D

Rationale: When a client is receiving digoxin therapy, it is crucial for the nurse to monitor liver function, serum electrolytes (especially potassium levels), and blood pressure. Digoxin is known to affect the heart's electrical activity and can lead to toxic effects if not managed properly. Monitoring liver function helps to assess the drug's metabolism and excretion. Checking serum electrolytes, especially potassium, is essential because digoxin toxicity can be exacerbated by electrolyte imbalances, particularly hypokalemia. Monitoring blood pressure is necessary because digoxin can influence cardiac contractility and heart rate, potentially affecting blood pressure. Therefore, monitoring all these parameters is vital to ensure the client's safety and therapeutic effectiveness of digoxin. Choices A, B, and C are incorrect because monitoring only one or two of these parameters may not provide a comprehensive assessment of the client's response to digoxin therapy.
