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. During the initial visit, which intervention is most important for the nurse to implement?

• A. Determine how the client is cared for when the caregiver is not present.
• B. Develop a client needs assessment and review it with the caregiver.
• C. Evaluate the caregiver's ability to care for the client's needs.
• D. Review with the caregiver the interventions provided each day.

Correct answer: A

Rationale: The most important intervention for the nurse to implement during the initial visit is to determine how the client is cared for when the caregiver is not present. This is crucial for ensuring continuous and adequate care, especially for a bed-bound client with multiple sclerosis who relies heavily on the caregiver. While developing a client needs assessment (choice B) and evaluating the caregiver's ability (choice C) are important, understanding the care plan in the caregiver's absence takes precedence. Reviewing daily interventions with the caregiver (choice D) is valuable but not as critical as knowing the care plan during the caregiver's absence.

4. A male client with hypertension, who received new antihypertensive prescriptions at his last visit, returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him 'feel bad'. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?

• A. Blindness due to cataracts
• B. Acute kidney injury due to glomerular damage
• C. Stroke secondary to hemorrhage
• D. Heart block due to myocardial damage

Correct answer: C

Rationale: The correct answer is C, 'Stroke secondary to hemorrhage.' Uncontrolled hypertension can lead to the weakening of blood vessels in the brain, increasing the risk of a stroke due to hemorrhage. This can result in serious neurological deficits or even death. Choices A, B, and D are incorrect because while hypertension can have various complications including vision changes, kidney damage, and heart problems, the most immediate and severe risk associated with uncontrolled hypertension is a stroke from cerebral hemorrhage.

5. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which intervention should the nurse implement first?

• A. Elevate the head of the bed.
• B. Administer oxygen therapy as prescribed.
• C. Assess the client's oxygen saturation.
• D. Obtain an arterial blood gas (ABG) sample.

Correct answer: C

Rationale: Assessing the client's oxygen saturation is the first priority in managing a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. Monitoring oxygen saturation levels helps in determining the effectiveness of the oxygen therapy and if adjustments are needed. Elevating the head of the bed can help with breathing but is not the first priority. Administering oxygen therapy as prescribed is important, but assessing the current oxygen saturation comes before administering more oxygen. Obtaining an arterial blood gas (ABG) sample may provide valuable information, but it is not the initial intervention needed in this situation.
