Question 1 of 5
A nurse is collecting data from a client who has isotonic fluid-volume deficit. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Isotonic fluid-volume deficit reduces blood volume, leading to a weak, thready pulse due to decreased cardiac output.
Question 2 of 5
At 0330, a nurse is caring for a client who is postoperative. The client's IV fluids are infusing at 120 mL/hr. How many mL of IV fluid should infuse by 0600? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: From 0330 to 0600 is 2.5 hours; 120 mL/hr × 2.5 hr = 300 mL.
Question 3 of 5
A nurse is monitoring a client who has dehydration and is receiving IV fluid replacement. Which of the following findings should the nurse identify as effectiveness of the treatment?
Correct Answer: B
Rationale: Urine output of 200 mL/4 hr (50 mL/hr) indicates improved kidney perfusion and hydration, suggesting effective treatment.
Question 4 of 5
A nurse is monitoring a client who is dehydrated. Which of the following laboratory findings should the nurse report to the provider?
Correct Answer: C
Rationale: An elevated BUN level (25 mg/dL) is above the normal range (10-20 mg/dL) and indicates dehydration due to increased protein breakdown and decreased renal perfusion, requiring immediate reporting to the provider.
Question 5 of 5
A nurse is collecting data from a client who has dehydration. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Cool skin is a typical finding in dehydration due to reduced peripheral circulation and vasoconstriction as the body maintains core temperature and blood pressure.
