Question 1 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.
Question 2 of 5
While assessing an older adult patient with fluid excess, the nurse notes the following: T = 98.6°F, P = 92, R = 18, BP = 166/88 mm Hg, bilateral crackles, oxygen saturation = 95%. Which action should the nurse take first?
Correct Answer: C
Rationale: Placing the patient in a high Fowler position maximizes lung expansion and alleviates dyspnea caused by fluid overload.
Question 3 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 4 of 5
A nurse is preparing to administer lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?(Round to the nearest whole number.)
Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
Question 5 of 5
A nurse is collecting data from a client. Which of the following findings should the nurse report to the charge nurse as an indicator of dehydration?
Correct Answer: C
Rationale: Skin tenting is a classic sign of dehydration, indicating reduced skin turgor due to fluid volume depletion.
