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 (KCl) 60 mEq x 1 now. Which action should the nurse take when caring for this client?
Correct Answer: C
Rationale: Potassium chloride is ideally administered through a central venous line because it is irritating to veins and can cause damage if given through a peripheral line. A central line reduces the risk of irritation and allows for safer infusion of potassium.
Question 2 of 5
A nurse is caring for a client with severe anemia. The provider placed an order for one unit of packed red blood cells (PRBCs) x 1 now. The nurse should anticipate the blood will be completely infused after how much time?
Correct Answer: D
Rationale: The standard time to infuse one unit of PRBCs is typically between 1.5 to 2 hours. This duration helps ensure the effective delivery of red blood cells while minimizing the risk of transfusion reactions.
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: Chronic alcohol use often results in nutritional deficiencies, and vomiting and diarrhea can further exacerbate this by depleting electrolytes. Hypomagnesemia is a common finding in long-term alcoholics due to poor dietary intake, gastrointestinal losses, and renal losses.
Question 4 of 5
A nurse is calculating a client's body mass index (BMI). Which of the following information does the nurse require?
Correct Answer: C
Rationale:
To calculate BMI, the client's height is essential. BMI is determined by dividing weight in kilograms by the square of height in meters (kg/m²). Accurate height measurement is crucial for this calculation.
Question 5 of 5
A nurse is caring for a client who is 1 day postoperative following a subtotal thyroidectomy. This morning's labs show a calcium level of 3 mg/dL (9-10.5 mg/dL). Which assessment would the nurse anticipate to be positive?
Correct Answer: D
Rationale: Chvostek's sign is a clinical indicator of hypocalcemia, where tapping on the facial nerve causes twitching of the facial muscles. With the client's calcium level of 3 mg/dL, which is significantly low, Chvostek's sign would likely be positive.
