Answer to Question 1

C
Serum lithium level must be checked at scheduled intervals throughout therapy. Older adult clients may have a decreased renal function, which places them at greater risk for developing lithium toxicity. Once a client's level is stable, testing usually occurs monthly.

Answer to Question 2

B
The Ballard tool looks at external physical characteristics and neuromuscular maturity. During the first 12 hours of life, plantar creases are reliable signs of gestational age. Creases cover two-thirds of the sole by 37 weeks and cover the entire sole at 40 weeks' gestation.
