Question 1 of 5
Which of the following complications can occur if a clotted cannula is flushed too aggressively?
Correct Answer: B
Rationale: Aggressively flushing a clotted cannula can dislodge a clot into the bloodstream, potentially causing serious complications like embolism.
Question 2 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 3 of 5
A nurse is collecting data from a client who has a calcium level of 8 mg/dL (9.0-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Tetany, involving muscle cramps and spasms, is a common manifestation of hypocalcemia due to increased neuromuscular excitability at low calcium levels.
Question 4 of 5
A nurse is collecting data from a client who has a sodium level of 128 mEq/L (136-145 mEq/L) Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Hyponatremia causes cellular swelling in the brain, leading to headaches and other neurological symptoms.
Question 5 of 5
A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 400 mL / (8 × 60) × 60 gtt/mL = 50 gtt/min.
