Nursing Elites

1. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?

• A. Serum potassium of 3.0 mEq/L
• B. Serum glucose of 200 mg/dl
• C. Serum pH of 7.30
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.

2. 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.

3. A client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). Which laboratory value should the nurse monitor closely?

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

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen), monitoring serum potassium levels closely is crucial. Epoetin alfa stimulates red blood cell production, which can lead to an increase in potassium levels. Hyperkalemia is a potential risk in these clients. Monitoring hemoglobin levels (choice A) is important in assessing the effectiveness of epoetin alfa therapy, but it is not the laboratory value that poses an immediate risk related to the medication. White blood cell count (choice B) and serum creatinine (choice D) are not directly affected by epoetin alfa therapy and are not the priority laboratory values to monitor in this case.

4. 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.

5. The nurse is administering an IV medication to a client with a history of anaphylaxis. Which intervention is most important for the nurse to implement?

• A. Stay with the client throughout the infusion.
• B. Keep emergency resuscitation equipment at the bedside.
• C. Obtain the client's allergy history.
• D. Ask the client about past allergic reactions to medications.

Correct answer: B

Rationale: Keeping emergency resuscitation equipment at the bedside is crucial in case the client experiences anaphylaxis during the infusion. While staying with the client throughout the infusion (Choice A) is important, having immediate access to emergency equipment takes priority in this situation. Obtaining the client's allergy history (Choice C) and asking about past allergic reactions to medications (Choice D) are relevant but do not address the immediate need for emergency intervention in case of anaphylaxis.
