Question 1 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 2 of 5
A nurse is collecting data from a client who has dehydration. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Cool skin is a typical finding in dehydration due to reduced peripheral circulation and vasoconstriction as the body maintains core temperature and blood pressure.
Question 3 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.
Question 4 of 5
Which is the most reliable method for monitoring improvement when restoring fluid balance?
Correct Answer: D
Rationale: Daily weights directly reflect changes in fluid retention or loss, providing the most reliable measure of fluid balance.
Question 5 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.
