Nursing Elites

1. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?

• A. White blood cell count
• B. Liver function tests
• C. Kidney function tests
• D. Complete blood count

Correct answer: B

Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.

2. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.

3. A client with cirrhosis is admitted with jaundice and ascites. Which laboratory value requires immediate intervention?

• A. Serum albumin of 3.0 g/dL
• B. Serum bilirubin of 3.0 mg/dL
• C. Serum ammonia level of 80 mcg/dL
• D. Serum sodium level of 135 mEq/L

Correct answer: C

Rationale: A serum ammonia level of 80 mcg/dL is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. High serum ammonia levels can lead to altered mental status, confusion, and even coma. Serum albumin (choice A) is often decreased in cirrhosis but does not require immediate intervention. Serum bilirubin (choice B) elevation is expected in cirrhosis and may not require immediate intervention unless very high. Serum sodium (choice D) within the given range is generally acceptable and does not require immediate intervention.

4. A client who is at 10-weeks gestation calls the clinic because she has been vomiting for the past 24 hours. The nurse determines that the client has no fever. Which instructions should the nurse give to this client?

• A. Come to the clinic to be seen by a healthcare provider
• B. Increase your fluid intake and rest at home
• C. Take over-the-counter antiemetics as needed
• D. Monitor your symptoms and call if they worsen

Correct answer: A

Rationale: The correct answer is to advise the client to come to the clinic to be seen by a healthcare provider. Persistent vomiting during pregnancy can lead to dehydration, which requires medical evaluation. Choice B is incorrect because solely increasing fluid intake and resting at home may not be sufficient to address the potential dehydration and underlying causes of vomiting. Choice C is not recommended without medical evaluation, as over-the-counter antiemetics should be used under healthcare provider guidance during pregnancy. Choice D is not the best option here because with persistent vomiting and risk of dehydration, immediate medical assessment is crucial to ensure the well-being of both the client and the fetus.

5. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be monitored closely?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.5 mEq/L
• C. Serum creatinine of 1.8 mg/dl
• D. Serum glucose of 200 mg/dl

Correct answer: C

Rationale: In a client with left-sided heart failure, monitoring serum creatinine is crucial to evaluate kidney function and fluid balance. Elevated creatinine levels can indicate impaired kidney function, which is common in heart failure due to decreased cardiac output and renal perfusion. Serum sodium levels (choice A) are important but are more closely associated with fluid balance and heart failure exacerbation. Serum potassium (choice B) is also important to monitor, but it is more closely linked to cardiac arrhythmias rather than kidney function. Serum glucose levels (choice D) are significant but are not the priority for monitoring in left-sided heart failure.
