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 client at 32 weeks of gestation with preeclampsia is receiving teaching from a nurse. Which statement by the client indicates an understanding of the teaching?

• A. I will take a daily aspirin to prevent blood clots.
• B. I will call my provider if I experience swelling in my hands.
• C. I should increase my calcium intake to prevent seizures.
• D. I will restrict my protein intake to prevent further kidney damage.

Correct answer: B

Rationale: The correct answer is B because swelling in the hands is a potential sign of worsening preeclampsia, and the client should report this to their provider. Choice A is incorrect since aspirin is not recommended in preeclampsia. Choice C is incorrect as calcium intake is not directly related to preventing seizures in preeclampsia. Choice D is incorrect because protein restriction is not the standard management for preventing further kidney damage in preeclampsia.

3. What is the first intervention for a patient experiencing anaphylactic shock?

• A. Administer epinephrine
• B. Administer corticosteroids
• C. Administer antihistamines
• D. Administer oxygen

Correct answer: A

Rationale: The correct answer is to administer epinephrine as the first intervention for a patient experiencing anaphylactic shock. Epinephrine is crucial in reversing the allergic reaction and restoring cardiovascular stability. Corticosteroids (Choice B) are not the first-line treatment for anaphylactic shock but may be used as an adjunct therapy. Antihistamines (Choice C) can help relieve itching and hives but are not as effective as epinephrine in treating the systemic effects of anaphylaxis. Oxygen (Choice D) may be necessary to support breathing in severe cases of anaphylaxis, but administering epinephrine takes precedence in the management of anaphylactic shock.

4. 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.

5. A nurse is assessing a client who is receiving a blood transfusion. Which of the following findings should the nurse identify as an indication of a hemolytic transfusion reaction?

• A. Low back pain.
• B. Bradycardia.
• C. Chills.
• D. Distended neck veins.

Correct answer: A

Rationale: The correct answer is A: Low back pain. Low back pain is a common sign of a hemolytic transfusion reaction, indicating the destruction of red blood cells. This finding requires immediate intervention as it can lead to serious complications such as renal failure. Bradycardia (choice B) is not typically associated with a hemolytic transfusion reaction. Chills (choice C) can be seen in febrile non-hemolytic transfusion reactions. Distended neck veins (choice D) are more indicative of fluid overload rather than a hemolytic reaction.
