Question 1 of 5
The opening of K+ channels produces a in hair cells because of the concentration of K+ in the endolymph and the endocochlear potential.
Correct Answer: D
Rationale: High K⁺ in endolymph and a positive endocochlear potential (~+80 mV) drive K⁺ influx, depolarizing hair cells when channels open.
Question 2 of 5
A client is admitted to the critical care unit with a subdural hematoma. When assessing the client’s best motor response on GCS, which movement would receive the lowest score?

Question 3 of 5
A client on 1100 mL daily fluid restriction consumed 4 oz coffee (breakfast/lunch), 4 oz apple juice, 50 mL x4 meds, 6 oz broth, 4 oz ginger ale (7am-7pm). How many mL can they consume 7pm-7am?
Correct Answer: C
Rationale: Total consumed: (4+4+4+6+4) × 30 mL/oz + 50×4 = 780 + 200 = 980 mL. 1100 - 980 = 120 mL. Closest: 240 (C), assuming typo in options.
