Nursing Elites

1. 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?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 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.

2. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?

• A. Serum potassium of 3.0 mEq/L
• B. Serum glucose of 200 mg/dl
• C. Serum pH of 7.30
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.

3. A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of CAD and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify signs of ischemia or a heart attack. While other diagnostic tests like chest X-ray, arterial blood gases, and echocardiogram may also be necessary in the evaluation of chest pain, they do not provide the initial direct assessment of cardiac ischemia that an ECG does.

4. A client with acute pancreatitis is admitted with severe abdominal pain. Which assessment finding requires immediate intervention?

• A. Severe abdominal distention
• B. Decreased urine output
• C. Decreased bowel sounds
• D. Increased heart rate

Correct answer: A

Rationale: Severe abdominal distention is a sign of worsening pancreatitis and can indicate complications like bowel obstruction or fluid accumulation. Immediate intervention is necessary to prevent further deterioration. Decreased urine output (Choice B) could indicate renal impairment, decreased bowel sounds (Choice C) are expected in pancreatitis due to paralytic ileus, and an increased heart rate (Choice D) is a common response to pain or stress in acute pancreatitis but may not require immediate intervention unless it is extremely high or persistent.

5. In a client with cirrhosis admitted with ascites and jaundice, which clinical finding requires immediate intervention?

• A. Peripheral edema
• B. Confusion and altered mental status
• C. Increased abdominal girth
• D. Yellowing of the skin

Correct answer: B

Rationale: Confusion and altered mental status in a client with cirrhosis and associated ascites and jaundice are indicative of hepatic encephalopathy, a serious complication that requires immediate intervention. This condition can progress rapidly and lead to coma if not addressed promptly. Peripheral edema (choice A) and increased abdominal girth (choice C) are common manifestations of fluid retention in cirrhosis but may not require immediate intervention unless severe. Yellowing of the skin (choice D) is a classic sign of jaundice, which is already known in this client and may not necessitate immediate intervention unless associated with other concerning symptoms.
