Nursing Elites

1. A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?

• A. Liver function tests
• B. Complete blood count
• C. Serum creatinine
• D. Prothrombin time

Correct answer: C

Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.

2. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

3. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. What action should the nurse take?

• A. Encourage the UAP to remain in the client's room until the hand rub is completed.
• B. Explain that the hand rub can be completed in less than 2 minutes.
• C. Inform the UAP that handwashing helps to promote better asepsis.
• D. Determine why the UAP was not wearing gloves in the client's room.

Correct answer: B

Rationale: The correct answer is B. Alcohol-based hand rubs are effective with a shorter rub time, typically around 20-30 seconds. Standing at the bedside for 2 minutes to rub hands thoroughly is unnecessary and can lead to wastage of resources. It's essential for the nurse to educate the UAP on proper hand hygiene techniques to ensure efficient and effective infection control practices. Choices A, C, and D are incorrect because encouraging the UAP to remain in the client's room, discussing handwashing instead of hand rubs, and questioning glove use are not the most appropriate actions in this scenario.

4. An older female client tells the nurse that her muscles have gradually been getting weaker. What is the best initial response by the nurse?

• A. Explain that this is an expected occurrence with aging.
• B. Observe the lower extremities for signs of muscle atrophy.
• C. Review the medical record for recent diagnostic test results.
• D. Ask the client to describe the changes that have occurred.

Correct answer: D

Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.

5. In a client with liver cirrhosis admitted with ascites and jaundice, which laboratory value is most concerning to the nurse?

• A. Serum albumin of 3.0 g/dl
• B. Bilirubin of 3.0 mg/dl
• C. Ammonia level of 80 mcg/dl
• D. Prothrombin time of 18 seconds

Correct answer: C

Rationale: An elevated ammonia level of 80 mcg/dl is most concerning in a client with liver cirrhosis because it may indicate hepatic encephalopathy, a serious complication. Serum albumin, though low, is expected in cirrhosis and contributes to ascites. Bilirubin elevation is common in liver disease but may not be the most concerning in this case. Prothrombin time is typically prolonged in liver disease but may not be as acute as an elevated ammonia level suggesting hepatic encephalopathy.
