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 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.
Question 3 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 4 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 5 of 5
A nurse is caring for a client whose serum potassium level is 5.3 mEq/L (3.5-5 mEq/L). The nurse should anticipate a prescription for which of the following medications?
Correct Answer: C
Rationale: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by lowering serum potassium levels through ion exchange in the intestines.
