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. In preparing assignments for the shift, which client is best for the charge nurse to assign to a practical nurse (PN)?

• A. An older client who fell yesterday and is now complaining of diplopia.
• B. An adult newly diagnosed with type 1 diabetes and high cholesterol.
• C. A client with pancreatic cancer who is experiencing intractable pain.
• D. An older client post-stroke who is aphasic with right-sided hemiplegia.

Correct answer: D

Rationale: The best client for the charge nurse to assign to a practical nurse (PN) is an older client post-stroke who is aphasic with right-sided hemiplegia. This client is stable and suitable for care by a PN under supervision. Choices A, B, and C present clients with more complex and acute conditions that would require a higher level of nursing expertise and intervention.

3. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.8 mg/dL
• D. Blood glucose of 200 mg/dL

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.

4. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?

• A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
• B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
• C. The additive effect of multiple medications has caused the blood pressure to drop too low.
• D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.

Correct answer: C

Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.

5. At 0600 while admitting a woman for a scheduled repeat cesarean section (C-Section), the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Ensure preoperative lab results are available
• B. Start prescribed IV with lactated Ringer's
• C. Inform the anesthesia care provider
• D. Contact the client's obstetrician

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the anesthesia care provider. The patient's ingestion of coffee violates the NPO (nothing by mouth) guidelines before surgery, which increases the risk of aspiration during anesthesia. Informing the anesthesia care provider promptly allows for appropriate assessment and decision-making regarding the patient's anesthesia plan. Ensuring preoperative lab results, starting an IV, or contacting the obstetrician can be important steps but addressing the NPO violation and its implications on anesthesia safety take precedence.
