ATI Nursing 4650 Comprehensive Exam Questions
Extract:
Question 1 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
Correct Answer: D
Rationale: An abnormally prominent U wave is a classic EKG finding in hypokalemia, as it prolongs the repolarization phase. Inverted P waves, wide QRS, and elevated ST segments are not typically associated with hypokalemia.
Question 2 of 5
A school nurse identifies that a child has pediculosis capitis and educates the child's parents about the condition. Which of the following statements by the parents indicates an understanding of the teaching?
Correct Answer: C
Rationale: Washing clothing, bedding, and towels in hot water kills lice and eggs, preventing reinfestation. While being lice-free before school return and treating family members are important, they are less comprehensive. Throwing out toys is unnecessary if they can be sealed or cleaned.
Question 3 of 5
A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hr. The drop factor of the manual IV tubing is 15 gtts/mL. The nurse should adjust the flow rate to deliver how many drops per minute? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale: The calculation involves dividing the total volume (250 mL) by the infusion time (120 minutes) and multiplying by the drop factor (15 gtts/mL). Simplified, this yields approximately 2 gtts/minute after rounding to the nearest whole number.
