Extract:
Question 1 of 5
A nurse is preparing to administer dextrose 5% in water (DSW) 100 mL to infuse over 1 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: B
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 100 mL / 60 min × 15 gtt/mL = 25 gtt/min.
Question 2 of 5
A nurse is assisting with the care of a client who has hypocalcemia. For which of the following signs should the nurse monitor?
Correct Answer: B
Rationale: Chvostek's sign, facial muscle twitching when the facial nerve is tapped, is a classic indicator of hypocalcemia.
Question 3 of 5
A nurse is assisting with the care of a client who is hypovolemic due to blood loss following a motor-vehicle crash and needs a blood transfusion immediately. The nurse should anticipate a prescription for which of the following IV solutions while awaiting blood from a type and cross-match?
Correct Answer: B
Rationale: Lactated Ringer's, an isotonic solution, restores fluid volume and electrolytes, making it suitable for hypovolemic shock while awaiting blood.
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 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.
