A client is ordered ampicillin 0.5 g po every 6 hours. On hand are ampicillin capsules labeled 250mg. How many capsules will the nurse administer for single dose?
The Correct Answer is ["2"]
Given:
Desired dose: Ampicillin 0.5 g PO
Available concentration: Ampicillin capsules 250 mg each
To find:
Number of capsules to administer for a single dose
Step 1: Convert desired dose to milligrams
We know that 1 gram (g) is equal to 1000 milligrams (mg). Therefore, to convert the desired dose from grams to milligrams, we multiply by 1000:
Desired dose (mg) = Desired dose (g) x 1000
Desired dose (mg) = 0.5 g x 1000 = 500 mg
Step 2: Calculate the number of capsules
To find the number of capsules, we divide the desired dose by the strength of each capsule:
Number of capsules = Desired dose / Capsule strength
Number of capsules = 500 mg / 250 mg/capsule = 2 capsules

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.
Correct Answer is A
Explanation
A) Practicing effleurage on the abdomen:
It is an excellent non-pharmacological pain management technique that can help distract the mother, reduce anxiety, and alleviate some of the discomfort associated with early labor. It also promotes relaxation and can help manage early labor pain effectively without the need for medications. This technique is easy to perform and can be done by the nurse or the partner, providing emotional support along with pain relief.
B) Beginning epidural anesthesia:
Epidural anesthesia is typically not initiated in the early phase of labor unless there is a specific indication or a desire for significant pain relief early in the process. An epidural is more commonly offered in the later stages of labor, when the pain is more intense and the cervix is further dilated. Starting an epidural too early could expose the mother to unnecessary risks and is generally not recommended unless it's requested or deemed medically necessary.
C) Using an opioid antagonist, such as Butorphanol:
Opioids, including Butorphanol, can have side effects such as drowsiness, nausea, and respiratory depression in both the mother and fetus. These medications are more commonly used in later stages of labor or when more potent pain relief is required. Additionally, opioid antagonists like Butorphanol may not be the best choice for a client who is experiencing anxiety and mild to moderate pain in the early phase, as they may not provide the relaxation and coping support that non-pharmacological methods like effleurage offer.
D) Immersing the client in hot water in a pool or Jacuzzi:
While immersion in water can be a helpful method of pain relief, especially during labor, it is generally recommended in the later stages of labor or when the cervix is dilated enough for water immersion to be safely utilized. Immersion in hot water may not be appropriate for all patients and could potentially lead to risks like overheating or changes in blood pressure. Additionally, the early phase of labor often involves less intense pain, and less invasive methods like effleurage are usually preferred first to manage discomfort and reduce anxiety.
