1. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

Correct answer: D

Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.

2. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

Correct answer: A

Rationale: Corrected Rationale: An electrocardiogram (ECG) should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify changes indicative of cardiac ischemia or infarction. Chest X-ray (Choice B) is not the initial diagnostic test for assessing chest pain related to myocardial infarction. Arterial blood gases (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for myocardial infarction. An echocardiogram (Choice D) may provide valuable information about cardiac structure and function, but it is not the first-line diagnostic test for acute chest pain in a client with a history of myocardial infarction.

3. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

4. The nurse is assessing a female client's blood pressure because she reported feeling dizzy. The blood pressure cuff is inflated to 140 mm Hg and as soon as the cuff is deflated a Korotkoff sound is heard. Which intervention should the nurse implement next?

Correct answer: A

Rationale: If a Korotkoff sound is heard immediately upon deflation, it may indicate an inaccurate reading. Waiting and palpating the systolic pressure can help confirm the accuracy of the measurement. Choice A is the correct intervention because it allows the nurse to ensure the accuracy of the blood pressure reading. Choice B is incorrect as increasing the inflation pressure is not necessary in this situation. Choice C is also incorrect as switching to a larger cuff is not warranted based on the information provided. Choice D is incorrect because documenting the finding as normal without further verification could lead to inaccurate information.

5. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

Correct answer: A

Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium closely is essential. Erythropoietin therapy can lead to increased red blood cell production, which may cause potassium levels to rise, potentially resulting in hyperkalemia. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because they are not directly impacted by erythropoietin therapy in the context of CKD.
