Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A healthcare professional is preparing to administer an IV fluid bolus of 500 mL over 4 hours to a client who is dehydrated. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 75 mL/hr.
• B. 100 mL/hr.
• C. 125 mL/hr.
• D. 150 mL/hr.

Correct answer: C

Rationale: Setting the IV pump to 125 mL/hr ensures the correct infusion rate for delivering 500 mL over 4 hours. To calculate the mL/hr rate, divide the total volume to be infused (500 mL) by the total time for infusion (4 hours): 500 mL / 4 hours = 125 mL/hr. Choice A (75 mL/hr) is too low and would result in an insufficient infusion rate, potentially delaying fluid resuscitation. Choice B (100 mL/hr) would also be too low and not deliver the fluid within the specified time frame. Choice D (150 mL/hr) is too high and would infuse the fluid too quickly, potentially causing fluid overload and complications.

3. A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the unit due to a staffing shortage. Which of the following clients should the nurse delegate to the LPN?

• A. A client who has an Hgb of 6.3 g/dl and a prescription for packed RBCs.
• B. A client who sustained a concussion and has unequal pupils.
• C. A client who is postoperative following a bowel resection with an NG tube.
• D. A client who fractured his femur yesterday and is experiencing shortness of breath.

Correct answer: C

Rationale: The correct answer is C because a client who is postoperative following a bowel resection with an NG tube can be delegated to an LPN as this involves routine postoperative care. Option A involves administering packed RBCs which requires assessment and monitoring for potential adverse reactions, not suitable for delegation to an LPN. Option B requires neurological assessment and close monitoring due to the concussion, which is beyond the scope of an LPN. Option D involves a client with a recent fracture and shortness of breath, which requires urgent assessment and intervention beyond the LPN's scope of practice.

4. A client with bipolar disorder and experiencing mania is under the care of a nurse. Which intervention should the nurse include in the plan?

• A. Encourage the client to spend time in the day room.
• B. Withdraw the client's TV privileges if they do not attend group therapy.
• C. Encourage the client to take frequent rest periods.
• D. Place the client in seclusion when they exhibit signs of anxiety.

Correct answer: C

Rationale: Encouraging the client to take frequent rest periods is the appropriate intervention when caring for a client with bipolar disorder experiencing mania. During manic episodes, individuals often exhibit hyperactivity and may become exhausted. Rest periods can help reduce these symptoms. Choices A, B, and D are incorrect. Spending time in the day room may not address the client's need for rest, withdrawing TV privileges is not directly related to managing mania symptoms, and placing the client in seclusion when anxious can escalate the situation rather than promoting a calming environment.

5. A nurse is caring for a newborn who is 1-day-old and receiving phototherapy for jaundice. Which of the following actions should the nurse take?

• A. Feed the infant 30 ml (1 oz) of glucose water every 2 hours.
• B. Keep the infant's head covered with a cap.
• C. Ensure that the newborn wears a diaper.
• D. Apply lotion to the newborn every 4 hours.

Correct answer: C

Rationale: The correct action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent skin irritation during phototherapy. Choice A is incorrect as newborns should be breastfed or formula-fed, not given glucose water. Choice B is unnecessary and may interfere with the effectiveness of phototherapy. Choice D is inappropriate as lotions can interfere with the phototherapy and increase the risk of skin damage.
