Nursing Elites

1. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?

• A. Use of accessory muscles
• B. Oxygen saturation of 94%
• C. Carbon dioxide level of 45 mmHg
• D. Respiratory rate of 20 breaths per minute

Correct answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

2. The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?

• A. Serum creatinine of 1.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Hemoglobin of 12 g/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.

3. 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.

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

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Serum glucose level

Correct answer: B

Rationale: In a client with left-sided heart failure, monitoring serum potassium levels is crucial. This helps in assessing kidney function and fluid balance. Elevated potassium levels can result from impaired kidney function, which is common in heart failure. Monitoring sodium levels (choice A) is important in heart failure but not specifically related to left-sided heart failure. Serum creatinine (choice C) reflects kidney function but is not the most critical value to monitor in this case. Serum glucose level (choice D) is important but not the priority when assessing left-sided heart failure.

5. Following discharge teaching, a male client with a duodenal ulcer tells the nurse he will drink plenty of dairy products to help coat and protect his ulcer. What is the best follow-up action by the nurse?

• A. Remind the client that it is also important to switch to decaffeinated coffee and tea.
• B. Suggest that the client also plans to eat frequent small meals to reduce discomfort.
• C. Review with the client the need to avoid foods that are rich in milk and cream.
• D. Reinforce this teaching by asking the client to list a dairy food that he might select.

Correct answer: C

Rationale: The correct answer is C because diets rich in milk and cream stimulate gastric acid secretion, which can exacerbate a duodenal ulcer. Therefore, it is essential to avoid foods that are rich in milk and cream. Choice A is incorrect because switching to decaffeinated coffee and tea does not address the issue of avoiding milk and cream products. Choice B is incorrect because while eating frequent small meals can help with discomfort, it does not address the specific issue of avoiding milk and cream. Choice D is incorrect as it does not address the need to avoid milk and cream products.
