Adult Health 2 Exam 1
1. A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?
- A. Administer insulin as prescribed
- B. Provide a carbohydrate-controlled snack
- C. Encourage physical activity
- D. Recheck the blood sugar
Correct answer: A
Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.
2. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?
- A. Serum glucose of 180 mg/dL
- B. Blood pH of 7.30
- C. Positive urine ketones
- D. Serum bicarbonate of 25 mEq/L
Correct answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
3. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?
- A. Phenytoin level
- B. Sodium level
- C. Hemoglobin level
- D. White blood cell count
Correct answer: A
Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.
4. The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?
- A. Pursed-lip breathing
- B. Hyperresonance on percussion
- C. Bradycardia
- D. High-pitched inspiratory crackles
Correct answer: A
Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.
5. A client with heart failure is prescribed a low-sodium diet. The nurse notices the client's meal tray contains high-sodium foods. What action should the nurse take?
- A. Educate the client about the importance of a low-sodium diet
- B. Replace the meal with a low-sodium option
- C. Report the error to the dietary department
- D. Encourage the client to avoid eating the high-sodium foods
Correct answer: B
Rationale: The correct action for the nurse to take in this situation is to replace the high-sodium meal with a low-sodium option. This immediate intervention ensures that the client adheres to the prescribed low-sodium diet, crucial for managing heart failure and preventing fluid retention. Educating the client (Choice A) about the diet is important but not as urgent as ensuring they receive the correct meal. Reporting the error to the dietary department (Choice C) can be done after addressing the immediate issue. Encouraging the client to avoid high-sodium foods (Choice D) is not as effective as replacing the current meal with a suitable alternative.
