ATI RN Fundamentals Exam 6 Questions
Extract:
Question 1 of 5
A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1200 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero is applicable. Do not use a trailing zero.)
Correct Answer: 150
Rationale: The formula for the infusion rate is: (volume in mL / time in hours) x drop factor in gtts/mL = infusion rate in gtts/min. The drop factor is usually given on the IV tubing package and varies depending on the type of tubing used. For this question we can assume a drop factor of 15 gtts/mL which is common for macrodrip tubing. Plugging in the numbers we get: (1200 mL / 8 hr) x 15 gtts/mL = 2250 gtts/hr.
To convert from gtts/hr to mL/hr we divide by the drop factor: 2250 gtts/hr / 15 gtts/mL = 150 mL/hr.
Therefore the nurse should set the IV pump to deliver 150 mL/hr.
Question 2 of 5
A nurse is performing an assessment of an older adult client in an assisted living facility. Which of the following findings is the highest priority for the nurse to address when planning care?
Correct Answer: A
Rationale: An unsteady gait increases the risk of falls which can lead to serious injuries in older adults. Ensuring safety and preventing falls is a priority. Short-term memory loss is common in older adults but it may not pose an immediate risk to safety. Hearing loss while important may not be an immediate safety concern unless it significantly impacts the individual's ability to communicate or hear warnings. Frequent constipation is a common concern in older adults but may not pose an immediate threat to safety. Falls prevention takes precedence in this scenario.
Question 3 of 5
A nurse is teaching a client who is to receive transcutaneous electrical nerve stimulation (TENS) for pain management. The nurse should inform the client that TENS relieves pain by
Correct Answer: C
Rationale: TENS does not primarily work by providing distraction from pain. While relaxation may be a secondary effect the primary mechanism of TENS is not to elicit a relaxation response. TENS works by modulating the transmission of the pain impulse disrupting pain signals from reaching the brain. TENS does not primarily work by promoting increased circulation to the painful area.
Question 4 of 5
A nurse is caring for a client who has a dysrhythmia. Which of the following techniques is appropriate for the nurse to use to assess for a pulse deficit?
Correct Answer: A
Rationale: Obtaining apical and radial rates simultaneously allows the nurse to assess for a pulse deficit by comparing the two rates. A pulse deficit is present when the apical rate (heard with a stethoscope) is greater than the radial rate (palpated at the wrist). Palpating pulses in the lower extremities is not specific for assessing a pulse deficit and may not accurately reflect the cardiac output. Checking blood pressure in left and right arms assesses for blood pressure differences but does not specifically address a pulse deficit. Comparing the pulse strength in the upper extremities does not directly assess for a pulse deficit; simultaneous assessment of apical and radial rates is more appropriate.
Question 5 of 5
A nurse is assessing a client's lower extremities and notes 6 mm pitting edema. Which of the following is appropriate documentation of this assessment finding?
Correct Answer: C
Rationale: 1+ pitting edema is mild with a slight indentation. 4+ pitting edema is severe with a deep indentation that lasts a long time. 3+ pitting edema is moderate with a deeper indentation that takes some time to rebound. 2+ pitting edema is moderate with a slight indentation that rebounds fairly quickly.
