Using abbreviations and the rules of the metric system, express the following quantities correctly: Six hundredth:
600 g
0.06 g
0.006
0.6 g
The Correct Answer is B
A) 600 g
This is incorrect because it represents the quantity 600 grams, which is a significantly larger amount than "six hundredth." The phrase "six hundredth" refers to six out of 100, or 0.06 in decimal form. In the metric system, 600 grams would indicate a much higher quantity, far from what is requested. Therefore, this option does not fit the definition of "six hundredth."
B) 0.06 g
The term "six hundredth" refers to six parts out of one hundred, which is mathematically expressed as 0.06. In the metric system, it is common to represent small quantities of mass, such as grams, in decimal form. The number 0.06 is precisely six hundredths, and the proper representation for this in terms of grams is 0.06 g. This is the correct scientific notation for the given quantity, as it accurately reflects six hundredths of a gram.
C) 0.006 g
This is incorrect because 0.006 grams represents six thousandths, not six hundredths. In decimal notation, six thousandths would be represented as 0.006, which is one order of magnitude smaller than six hundredths. The difference between 0.006 and 0.06 is significant. While both numbers are small, 0.006 would refer to an even smaller quantity than 0.06, which is not in line with the intended meaning of "six hundredth."
D) 0.6 g
While 0.6 grams may appear similar at first glance, it represents six-tenths (6/10), not six hundredths (6/100). The number 0.6 is much larger than 0.06, and it would be used to indicate a weight that is 60% of a gram, not a small fraction like six hundredths.

Correct Answer is B
Explanation
Given:
Ordered volume of Isomil: 12 oz
Step 1: Determine the volume of Isomil needed for 1/4 strength:
Volume of Isomil for 1/4 strength = Original volume x (1/4)
Volume of Isomil for 1/4 strength = 12 oz x (1/4)
Volume of Isomil for 1/4 strength = 3 oz
Step 2: Calculate the volume of solvent (water) needed:
Solvent volume = Original volume - Volume of Isomil for 1/4 strength
Solvent volume = 12 oz - 3 oz
Solvent volume = 9 oz
Step 3: Convert ounces to milliliters:
1 oz = 29.5735 mL
Solvent volume (mL) = 9 oz x 29.5735 mL/oz
Solvent volume (mL) = 266.1615 mL
Step 4: Round to the nearest whole number:
Solvent volume (mL) ≈ 270 mL
Correct Answer is C
Explanation
A) Yes. Antacids can help alleviate heartburn caused by digoxin.
While antacids can help relieve heartburn, they do not directly alleviate heartburn caused by digoxin. In fact, antacids can interact with digoxin in a way that affects its absorption, potentially leading to suboptimal therapeutic effects.
B) Yes, you can take antacids with digoxin without any interactions.
Antacids can interact with digoxin and reduce its absorption, particularly those that contain aluminum, magnesium, or calcium. Therefore, it is important to space the administration of these medications to avoid potential drug interactions.
C) Yes, but make sure to take the antacid at least 2 hours before or after taking digoxin.. Antacids, especially those containing aluminum, calcium, or magnesium, can decrease the absorption of digoxin, reducing its effectiveness. To prevent this interaction, the nurse should advise the client to take the antacid at least 2 hours before or after taking digoxin to ensure that digoxin is properly absorbed and remains effective.
D) No, antacids can decrease the absorption of digoxin and result in a decreased drug effect.
While this statement is partly true in that antacids can decrease digoxin absorption, it is too absolute to recommend avoiding antacids altogether. The key is proper timing—taking antacids at least 2 hours apart from digoxin.
