ATI Nursing 100 Day Exam 4 Fundamentals Questions
Extract:
Question 1 of 5
A client has a serum potassium level of 6.3 mEq/L. The nurse recognizes that the highest priority intervention(s) for this client are to:
Correct Answer: C,E
Rationale: Hyperkalemia (6.3 mEq/L above normal 3.5-5.0 mEq/L) risks cardiac dysrhythmias and neuromuscular issues requiring immediate assessment for muscle weakness/flaccid paralysis and cardiac monitoring to detect life-threatening arrhythmias. Diluting potassium or encouraging potassium-rich foods worsens hyperkalemia and intake/output monitoring is secondary.
Question 2 of 5
The nurse recognizes that which is not a necessary feature of a team?
Correct Answer: C
Rationale: Teams can function effectively across departments as collaboration is based on shared goals not physical proximity. Shared responsibility ensures collective accountability mutual interdependence allows individual contributions toward team goals and a common purpose aligns efforts all of which are essential for team dynamics.
Question 3 of 5
It is most critical for the nurse to use a filtered needle when preparing a parenteral medication that:
Correct Answer: A
Rationale: A filtered needle prevents glass particles from an ampule (broken to access medication) entering the syringe reducing risks of tissue damage or embolism. Mixing medications reconstitution or clear solutions do not inherently produce particles requiring filtration.
Question 4 of 5
The nurse is assessing a client who exhibits positive Trousseau's and Chvostek's signs. What laboratory value would validate these clinical findings? A serum:
Correct Answer: D
Rationale: Low calcium (6.9 mg/dL below normal 8.5-10.2 mg/dL) causes neuromuscular excitability leading to Trousseau’s (arm spasm with cuff inflation) and Chvostek’s (facial twitching) signs. Normal potassium (3.5-5.0 mEq/L) phosphate (2.5-4.5 mg/dL) and magnesium (1.8-2.5 mEq/L) do not explain these findings.
Question 5 of 5
The nurse is transcribing a medication order and schedules dosing for 10:00 AM 2:00 PM and 6:00 PM. Which medication order is consistent with this schedule?
Correct Answer: B
Rationale: Diazepam three times daily fits the 10:00 AM 2:00 PM and 6:00 PM schedule for three doses within a day. Twice daily (Propranolol) requires wider intervals q4 hours (Cephalexin Morphine) implies every 4 hours not specific times and Morphine is PRN not scheduled.
