1. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?
- A. Serum glucose of 350 mg/dL.
- B. Serum potassium of 2.8 mEq/L.
- C. Serum sodium of 136 mEq/L.
- D. Serum bicarbonate of 20 mEq/L.
Correct answer: B
Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.
2. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?
- A. The client's extremities are paralyzed.
- B. The peripheral nerve stimulator causes twitching.
- C. The client clenches fist upon command.
- D. The client's Glasgow Coma Scale score is 14.
Correct answer: A
Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.
3. A client with a history of chronic heart failure is experiencing severe shortness of breath and has pink, frothy sputum. Which action should the nurse take first?
- A. Administer morphine sulfate.
- B. Place the client in a high Fowler's position.
- C. Initiate continuous ECG monitoring.
- D. Prepare the client for intubation.
Correct answer: B
Rationale: In a client with chronic heart failure experiencing severe shortness of breath and pink, frothy sputum, the priority action for the nurse is to place the client in a high Fowler's position. This position helps improve lung expansion, ease breathing, and enhance oxygenation by reducing venous return and decreasing preload on the heart. It is crucial to address the client's respiratory distress promptly before considering other interventions. Administering morphine sulfate (choice A) may be appropriate later to relieve anxiety and reduce the work of breathing, but positioning is the priority. Continuous ECG monitoring (choice C) and preparing for intubation (choice D) are important but secondary to addressing the respiratory distress and optimizing oxygenation.
4. A client who has just started taking levodopa-carbidopa (Sinemet) for Parkinson's disease reports experiencing nausea. What should the nurse recommend to the client?
- A. Take the medication on an empty stomach.
- B. Consume a low-protein snack with the medication.
- C. Increase your intake of dairy products.
- D. Stop taking the medication and notify your healthcare provider.
Correct answer: B
Rationale: Nausea is a common side effect of levodopa-carbidopa (Sinemet). Consuming a low-protein snack with the medication can help reduce nausea. The protein in food can compete with levodopa for absorption, so taking it with a low-protein snack may improve its effectiveness and reduce gastrointestinal side effects. Option A is incorrect as taking the medication on an empty stomach may exacerbate nausea. Option C is incorrect because increasing intake of dairy products is not recommended to alleviate nausea. Option D is incorrect because abruptly stopping the medication without healthcare provider guidance can lead to adverse effects.
5. In a patient with chronic kidney disease (CKD) receiving erythropoietin therapy, what laboratory result should the nurse monitor to evaluate the effectiveness of this therapy?
- A. Serum creatinine
- B. White blood cell count
- C. Hemoglobin level
- D. Serum potassium
Correct answer: C
Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.
