A client is ordered digoxin 0.25mg po. daily. On hand is a liquid in a dropper bottle labeled 500mcg/10mL. How many milliliters will be administered?
The Correct Answer is ["5"]
Given:
Desired dose: Digoxin 0.25 mg PO daily
Available concentration: Digoxin 500 mcg/10 mL
To find:
Volume to administer (in mL)
Step 1: Convert desired dose to micrograms
We know that 1 milligram (mg) is equal to 1000 micrograms (mcg). Therefore, to convert the desired dose from mg to mcg, we multiply by 1000:
Desired dose (mcg) = Desired dose (mg)x 1000
Desired dose (mcg) = 0.25 mg x 1000 = 250 mcg
Step 2: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 3: Substitute the values
Plugging in the given values, we get:
(250 mcg) / (500 mcg/10 mL) = Volume to administer
Step 4: Simplify
To simplify, we can invert the denominator and multiply:
(250 mcg) x (10 mL / 500 mcg) = Volume to administer
The "mcg" units cancel out, leaving us with:
(250 x 10 mL) / 500 = Volume to administer
Step 5: Calculate
Performing the multiplication and division, we get:
2500/ 500 = Volume to administer
5 mL = Volume to administer

Correct Answer is D
Explanation
A) At the umbilicus:
After delivery, the fundus is typically located at or just below the umbilicus in the immediate postpartum period, but it will gradually descend over the next few days. By 8 hours postpartum, the fundus is often slightly below the umbilicus, not directly at the umbilicus. The fundus will continue to shrink in size and move downward toward the pelvic region as the uterus contracts and involutes.
B) At a non-palpable depth:
A fundus that is non-palpable is generally expected later in the postpartum period, typically by 10-14 days after delivery, as the uterus contracts and returns to its pre-pregnancy size. At 8 hours postpartum, the fundus is still palpable, generally just below the umbilicus, and should be evaluated for firmness and position.
C) Just above the symphysis pubis:
The fundus is usually higher than the symphysis pubis at 8 hours postpartum, as it is still in the process of descending from the higher position it occupied during pregnancy. It would be expected to be just below the umbilicus or about 1 to 2 finger widths below it. By the second or third day postpartum, the fundus begins to move lower toward the symphysis pubis as it continues to involute.
D) Just below the umbilicus:
Eight hours after delivery, the nurse should expect to palpate the fundus just below the umbilicus. This is a typical finding as the uterus begins to contract and shrink after the delivery of the placenta. The fundus will descend about 1-2 cm per day postpartum, so by 8 hours, it is usually just slightly below the level of the umbilicus.
Correct Answer is B
Explanation
A) Milia:
Milia are tiny white or yellowish cysts that appear on a newborn's face, particularly on the nose, chin, or forehead. They are caused by the accumulation of keratin under the skin. Milia usually disappear within a few weeks of life and are not related to the pinkish marks described in the question.
B) Telangiectatic nevi (stork bites):
This finding is consistent with telangiectatic nevi, also known as stork bites. These are flat, irregular, pinkish-red marks often found on the forehead, eyelids, and nape of the neck. They are caused by dilated capillaries in the skin and are common in newborns. The marks blanch when pressed and are usually harmless, disappearing within the first 1-2 years of life. This is the correct answer based on the description provided in the question.
C) Nevus flammeus (port wine stain):
A port wine stain is a dark red to purple, flat birthmark caused by capillary malformations. Unlike stork bites, a port wine stain does not blanch when pressed and is typically present for life. It usually appears on the face, neck, or arms, and the coloration remains the same over time.
D) Nevus vasculosus (strawberry mark):
A strawberry mark is a raised, red, and bumpy birthmark that results from proliferation of capillaries. These marks typically appear in the first few weeks of life and grow in size before eventually shrinking and disappearing by the age of 5-10 years. Strawberry marks are not flat, pinkish, or blanchable, making this option unlikely in the scenario described.
