The lithium level is too low
The lithium level is therapeutic
Lithium is not usually monitored with blood levels
The lithium level is too high
The Correct Answer is B
A. A lithium level of 0.9 mEq/L falls within the therapeutic range for lithium, so it is not too low.
B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.

Correct Answer is ["28"]
Explanation
2 cups of coffee: 2 cups 8 oz/cup = 16 oz
1 soft drink: 12 oz
Total intake from 1500 to 2100 = 16 oz (coffee) + 12 oz (soft drink) = 28 oz
From 2100 to 2300 (2 hours):
No additional intake mentioned in the question.
Total intake from 1500 to 2300 = 28 oz (from 1500 to 2100)
Therefore, the total intake from 1500 to 2300 is 28 ounces.
Correct Answer is A
Explanation
A. The benefit to eating frequent small meals during the day: Nonselective beta-blockers can mask symptoms of hypoglycemia, making it harder for patients with diabetes to recognize low
blood sugar levels. Eating frequent small meals can help stabilize blood sugar levels and reduce the risk of hypoglycemia.
B. Perform more frequent blood glucose checks due to effects of the drug: While it's important for patients with diabetes to monitor their blood glucose levels regularly, this instruction doesn't directly address the potential masking of hypoglycemia symptoms by beta-blockers.
C. The need to weight himself once per week at the same time of the day: Weight monitoring is important for overall health management but is not specifically related to the use of nonselective beta-blockers in diabetes management.
D. The correct method for taking their own apical pulse: Knowing how to take one's own apical pulse is important for some individuals, but it's not directly related to the management of
diabetes with nonselective beta-blockers.
