Question 1 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.
Question 2 of 5
A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Tingling of the lips is a classic sign of hypocalcemia, resulting from increased neuromuscular excitability causing paresthesia.
Question 3 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 4 of 5
A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Tingling of the lips is a classic sign of hypocalcemia, resulting from increased neuromuscular excitability causing paresthesia.
Question 5 of 5
A nurse reviewing the laboratory of a client who had a total thyroidectomy discovers that his calcium level is 7 mg/dL (9-10.5 mg/dL). Which of the following client findings should the nurse expect?
Correct Answer: C
Rationale: Hypocalcemia, common post-thyroidectomy, can cause muscle tetany due to increased neuromuscular excitability.
