Nursing Elites

1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dL

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

2. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

3. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which intervention should the nurse implement first?

• A. Obtain a blood glucose level.
• B. Administer an anticoagulant as prescribed.
• C. Perform a neurological assessment.
• D. Administer aspirin as prescribed.

Correct answer: C

Rationale: Performing a neurological assessment is the priority in this situation as it helps in evaluating the cause of the new onset of confusion in a client with atrial fibrillation. This assessment will provide crucial information about the client's neurological status, which can guide further interventions. Obtaining a blood glucose level (Choice A) is important but should not be the first step when dealing with a new onset of confusion. Administering an anticoagulant (Choice B) or aspirin (Choice D) may be necessary depending on the underlying cause, but assessing the neurological status comes first to determine the appropriate course of action.

4. The nurse is preparing to administer an IV dose of ciprofloxacin to a client with a urinary tract infection. Which client data requires the most immediate intervention by the nurse?

• A. Serum creatinine of 4.5 mg/dL (398 μmol/L SI)
• B. Temperature of 101.3°F
• C. Blood pressure of 140/90 mmHg
• D. Heart rate of 88 bpm

Correct answer: A

Rationale: A serum creatinine level of 4.5 mg/dL indicates severe renal impairment, which requires immediate attention before administering ciprofloxacin. Elevated serum creatinine levels suggest decreased kidney function, and giving ciprofloxacin can further harm the kidneys. Monitoring and addressing renal function are crucial to prevent worsening of renal impairment and potential drug toxicity. The temperature, blood pressure, and heart rate are important parameters to assess, but in this scenario, the priority is to address the severe renal impairment before proceeding with ciprofloxacin administration.

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.
