Nursing Elites

1. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

2. A client diagnosed with type 1 diabetes receives insulin. He asks the nurse why he can't just take pills instead. What is the best response by the nurse?

• A. Insulin must be injected because it needs to work quickly.
• B. Insulin can't be in a pill because it is destroyed in stomach acid.
• C. Have you talked to your doctor about taking pills instead?
• D. I know it is tough, but you will get used to the shots soon.

Correct answer: B

Rationale: The correct answer is B because insulin cannot be taken orally as it gets destroyed by stomach acid. Choice A is incorrect as the speed of action is not the reason why insulin can't be in pill form. Choice C is incorrect as it doesn't address the nature of insulin. Choice D is incorrect as it doesn't provide a factual reason why insulin can't be in pill form.

3. A nurse manager is leading a discussion about ethical dilemmas. Which of the following situations should the nurse manager include as an example of an ethical dilemma?

• A. A visitor experiences a minor burn after spilling coffee
• B. A client receives an operation on the wrong side of her body
• C. A parent wants her 14-year-old adolescent to receive radiation treatment against his will
• D. A nurse witnesses another nurse administer an incorrect medication

Correct answer: C

Rationale: An ethical dilemma involves a situation where moral principles conflict, such as in the case of a parent wanting their adolescent to receive treatment against their will. In option A, a minor burn from spilled coffee does not present a conflict of moral principles. Option B describes a medical error, not necessarily a conflict of moral principles. Option D involves an issue of professional practice and patient safety but does not inherently pose a conflict of moral principles.

4. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

5. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.
