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 type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning?

• A. Serum glucose of 500 mg/dl
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.

3. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.

4. A client is admitted with a diagnosis of pneumonia and is receiving IV antibiotics. Which assessment finding indicates that the treatment is effective?

• A. Client reports less chest pain.
• B. Client's white blood cell count is decreasing.
• C. Client has a decreased respiratory rate.
• D. Client has clear breath sounds.

Correct answer: D

Rationale: The correct answer is D. Clear breath sounds indicate that the pneumonia is resolving and the treatment is effective. Breath sounds are often muffled or crackling in pneumonia due to the presence of fluid or inflammation in the lungs. Clear breath sounds suggest that the air is moving freely through the lungs, indicating improvement. Choices A, B, and C are less specific indicators of pneumonia resolution. While less chest pain and a decreasing white blood cell count can be positive signs, they are not as direct in indicating the effectiveness of pneumonia treatment as the presence of clear breath sounds. A decreased respiratory rate could be seen in various conditions and may not solely indicate the resolution of pneumonia.

5. A client with cirrhosis is admitted with hepatic encephalopathy. Which clinical finding is most concerning?

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

Correct answer: A

Rationale: Confusion and altered mental status are the most concerning clinical findings in a client with hepatic encephalopathy. These symptoms indicate worsening liver function and potential neurological complications, requiring immediate medical attention. Increased abdominal girth may suggest ascites, yellowing of the skin can indicate jaundice, and peripheral edema may be related to fluid retention, but in the context of hepatic encephalopathy, confusion and altered mental status take precedence due to the risk of rapid deterioration and the need for prompt management.
