Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?

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

Correct answer: D

Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.

2. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?

• A. Jaundice.
• B. Ascites.
• C. Spider angiomas.
• D. Asterixis.

Correct answer: D

Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.

3. A client begins taking an antidepressant drug during the second day of hospitalization. Which assessment is most important for the nurse to include in this client's plan of care while the client is taking the antidepressant?

• A. Appetite
• B. Mood
• C. Withdrawal
• D. Energy level

Correct answer: B

Rationale: Corrected Rationale: Monitoring the client's mood is essential when starting an antidepressant to assess for any changes or adverse effects related to the medication. Changes in mood can indicate the effectiveness of the antidepressant or potential side effects. Assessing appetite (Choice A) is important but not as crucial as monitoring mood in this context. Withdrawal symptoms (Choice C) are more relevant when discontinuing antidepressants rather than starting them. Energy level (Choice D) can be influenced by various factors and may not directly reflect the client's response to the antidepressant.

4. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?

• A. Increase the oxygen flow rate if shortness of breath occurs
• B. Use oxygen only when experiencing shortness of breath
• C. Do not adjust the oxygen flow rate without consulting a healthcare provider
• D. Use a humidifier with the oxygen to prevent dry mucous membranes

Correct answer: C

Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.

5. A client with a diagnosis of hypertension is prescribed a thiazide diuretic. Which potential side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypoglycemia

Correct answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Thiazide diuretics commonly cause potassium loss, which can lead to hypokalemia. Monitoring potassium levels is essential when a client is taking thiazide diuretics to prevent complications such as cardiac dysrhythmias. Choices A, B, and D are incorrect. Hyperkalemia (choice A) is an elevated level of potassium, which is not typically associated with thiazide diuretics. Hypernatremia (choice B) is an elevated level of sodium, and hypoglycemia (choice D) is low blood sugar, neither of which are directly linked to thiazide diuretic use.
