The physician orders atropine sulfate 300 mcg IM for preoperative medication. Looking at the label, how many milliliters will you administer?
The Correct Answer is ["3"]
Order: Atropine sulfate 300 mcg IM
Label: 0.5 mg (0.1 mg/mL)
Conversion:
0.5 mg = 500 mcg
Concentration: 0.1 mg/mL = 100 mcg/mL
Desired dose: 300 mcg
Volume to administer: 300 mcg ÷ 100 mcg/mL = 3 mL

Correct Answer is A
Explanation
a) Fluid retention: A weight increase of 6 pounds in 1 day is significant and may indicate fluid retention, which is commonly seen in conditions like heart failure or kidney disease.
b) Increased nutritional intake: A 6-pound weight gain is unlikely to be due to nutritional intake alone, especially over just a two-day period. This would more likely be seen over a longer timeframe.
c) Anorexia: Anorexia is associated with weight loss, not weight gain.
d) Weight loss: The patient has gained weight, not lost it.
Correct Answer is D
Explanation
a) Chloride 100 mEq/L: A chloride level of 100 mEq/L is within the normal range (98-107 mEq/L) and would not be concerning in this context.
b) Sodium 138 mEq/L: A sodium level of 138 mEq/L is within the normal range (135-145 mEq/L) and would not be concerning in this context.
c) Potassium 4.1 mEq/L: A potassium level of 4.1 mEq/L is within the normal range (3.5-5.0 mEq/L) and would not be concerning in this context.
d) Magnesium 1.0 mEq/L: A magnesium level of 1.0 mEq/L is low (normal range: 1.5-2.5 mEq/L), and low magnesium can cause neuromuscular symptoms such as tremors. This would be a concerning result in the context of the patient's hand and face tremors.
