ATI N100 Fundamentals Exam Questions
Extract:
Question 1 of 5
A nurse is caring for a client with severe hypokalemia. The provider places an order for IV potassium chloride (KCI) 60 mEq x1 now. Which action should the nurse take when caring for this client?
Correct Answer: C
Rationale: KCI should be administered via a central venous line to reduce vein irritation and ensure safe delivery.
Question 2 of 5
A nurse is providing dietary teaching for a client who takes furosemide (Lasix), a loop diuretic. The nurse should recommend which of the food is a great source of potassium?
Correct Answer: C
Rationale: Baked potatoes are an excellent source of potassium. A medium-sized baked potato with the skin can provide a significant amount of potassium, which is essential for maintaining normal heart function and muscle contraction.
Question 3 of 5
A nurse is caring for a client who is a long-term alcoholic. The client presents to the emergency department with vomiting and diarrhea for several days. Which findings would the nurse expect to find in this client?
Correct Answer: C
Rationale: Hypomagnesemia is common in long-term alcoholics due to poor dietary intake and gastrointestinal losses from vomiting and diarrhea, affecting cardiovascular and neuromuscular function.
Question 4 of 5
A nurse is caring for a client who has hypernatremia and requires IV fluid therapy. Which solution should the nurse prepare to infuse for this client?
Correct Answer: D
Rationale: Hypotonic solutions, such as 0.45% sodium chloride (half-normal saline) or dextrose 5% in water (D5W), are appropriate for treating hypernatremia. These solutions help dilute the excess sodium in the blood, reduce serum sodium levels, and facilitate a gradual correction of the imbalance.
Question 5 of 5
A nurse is caring for a client with a current blood potassium level of 5.4 mEq/L (3.5-5 mEq/L). Which finding would this client have?
Correct Answer: D
Rationale: Hyperkalemia can cause paresthesias, which are sensations of tingling or numbness, particularly in the extremities. This occurs due to the effect of elevated potassium levels on nerve and muscle function. As potassium is essential for maintaining normal neuromuscular function, deviations from normal levels can disrupt action potentials and lead to sensory disturbances like paresthesias.
