1. While a child is hospitalized with acute glomerulonephritis, the parents ask why blood pressure readings are taken so often. Which response by the nurse is most accurate?
- A. Elevated blood pressure must be anticipated and identified quickly
- B. Frequent monitoring helps ensure the medication is effective
- C. It is standard protocol for all hospitalized children
- D. We need to monitor for any potential kidney damage
Correct answer: A
Rationale: The correct answer is A: 'Elevated blood pressure must be anticipated and identified quickly.' Acute glomerulonephritis can lead to significant hypertension, making it crucial to monitor blood pressure frequently to promptly identify any elevation. Choice B is incorrect because while monitoring can help assess medication effectiveness, the primary reason for frequent blood pressure checks in this case is to detect elevated blood pressure. Choice C is incorrect as not all hospitalized children require such frequent blood pressure monitoring. Choice D is incorrect as the primary reason for monitoring blood pressure is to detect hypertension, rather than solely focusing on potential kidney damage.
2. The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which intervention should the nurse implement first?
- A. Encourage fluid intake to thin secretions.
- B. Administer a mucolytic agent.
- C. Increase humidity in the client's room.
- D. Perform deep suctioning as needed.
Correct answer: C
Rationale: Increasing humidity in the client's room is the first priority in managing thick, tenacious secretions in a client with a tracheostomy to facilitate airway clearance. This intervention helps to moisten secretions, making them easier to clear. Encouraging fluid intake (Choice A) can be beneficial, but increasing humidity should be addressed first. Administering a mucolytic agent (Choice B) and performing deep suctioning (Choice D) are interventions that can be considered after addressing humidity if necessary, but they are not the initial priority.
3. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?
- A. Serum potassium of 4.0 mEq/L
- B. Blood glucose of 200 mg/dl
- C. Serum creatinine of 1.5 mg/dl
- D. Serum potassium of 3.2 mEq/L
Correct answer: D
Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.
4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which clinical finding is most concerning to the nurse?
- A. Kussmaul respirations
- B. Blood glucose level of 300 mg/dl
- C. Serum potassium of 3.2 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.
5. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?
- A. White blood cell count
- B. Liver function tests
- C. Kidney function tests
- D. Complete blood count
Correct answer: B
Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.
