Nursing Elites

1. 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.

2. A client with end-stage renal disease (ESRD) is receiving hemodialysis. Which laboratory value should the nurse monitor closely?

• A. Serum calcium level of 9 mg/dl
• B. Serum potassium level of 4.5 mEq/L
• C. Serum creatinine level of 2.0 mg/dl
• D. Serum sodium level of 138 mEq/L

Correct answer: C

Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.

3. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dl
• D. Blood glucose of 150 mg/dl

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with CKD as it indicates hyperkalemia, which requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, particularly in patients with impaired kidney function. Serum sodium, creatinine, and blood glucose levels, while important, are not as acutely dangerous as severe hyperkalemia in this context.

4. The nurse is caring for a client following a myelogram. Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Complaint of headaches and stiff neck.
• B. Complaint of dizziness and nausea.
• C. Increased pain at the puncture site.
• D. Mild redness around the puncture site.

Correct answer: A

Rationale: The correct answer is A: Complaint of headaches and stiff neck. Headaches and stiff neck following a myelogram may indicate a cerebrospinal fluid (CSF) leak or other complications that require prompt medical attention. Reporting this finding immediately is crucial to prevent further complications. Choices B, C, and D are incorrect because while they may warrant monitoring and intervention, they are not as indicative of a potentially serious complication as the symptoms described in choice A.

5. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.
