Nursing Elites

1. A client with severe COPD is receiving oxygen therapy at 2 liters per minute via nasal cannula. The client's oxygen saturation level drops to 88% during ambulation. What action should the nurse take first?

• A. Increase the oxygen flow rate to 4 liters per minute.
• B. Instruct the client to rest until the oxygen saturation improves.
• C. Discontinue ambulation and return the client to bed.
• D. Encourage the client to breathe more deeply.

Correct answer: C

Rationale: In this scenario, the client's oxygen saturation level dropping during ambulation indicates an inadequate oxygen supply. The first action the nurse should take is to discontinue ambulation and return the client to bed. This helps stabilize the oxygen level by reducing the oxygen demand placed on the client during physical activity. Increasing the oxygen flow rate without addressing the underlying issue of oxygen saturation dropping may not be effective. Instructing the client to rest is not enough to address the immediate need for stabilization of oxygen levels. Encouraging the client to breathe more deeply may not be sufficient to overcome the oxygen saturation drop caused by inadequate oxygen supply during ambulation.

2. The nurse is caring for a client with chronic kidney disease (CKD). Which laboratory value should be reported to the healthcare provider immediately?

• A. Serum creatinine of 2.0 mg/dl
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.5 mEq/L
• D. Blood glucose of 150 mg/dl

Correct answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

3. The nurse enters a client's room to administer scheduled daily medications and observes the client leaning forward and using pursed lip breathing. Which action is most important for the nurse to implement first?

• A. Evaluate the oxygen saturation.
• B. Administer a bronchodilator.
• C. Assist the client to sit upright.
• D. Encourage slow, deep breathing.

Correct answer: A

Rationale: In this scenario, the nurse should first evaluate the oxygen saturation. This action is crucial as it provides immediate information on the client's respiratory status. Assessing the oxygen saturation can help determine the adequacy of oxygenation and guide further interventions. Administering a bronchodilator (Choice B) may be necessary based on assessment findings, but it should not be the first action without knowing the oxygen saturation level. While assisting the client to sit upright (Choice C) is generally beneficial for respiratory function, in this case, assessing oxygen saturation takes precedence. Encouraging slow, deep breathing (Choice D) can be helpful, but it is secondary to evaluating the oxygen saturation in this situation.

4. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding is most concerning to the nurse?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: 'Use of accessory muscles.' In a client with a history of COPD, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure, necessitating immediate intervention. This finding is concerning as it suggests the client is struggling to breathe adequately. Oxygen saturation of 90% (choice A) is low but may be expected in COPD patients; it requires monitoring and intervention but is not as immediately concerning as the use of accessory muscles. A respiratory rate of 24 breaths per minute (choice B) is within a normal range and, although slightly elevated, may be a typical response to pneumonia. Inspiratory crackles (choice D) can be a common finding in pneumonia and are not as indicative of impending respiratory failure as the use of accessory muscles.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Serum magnesium level

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.
