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","E"]
Explanation
A) Fusion of labia in female genitalia:
Fusion of the labia in a female newborn is not an expected finding. This could indicate a condition such as labial adhesion or an abnormality in the development of the genitalia. Normally, the labia in a female newborn are separated. Any signs of fusion would require further evaluation by the healthcare provider.
B) Erythema toxicum on newborn's skin:
Erythema toxicum is a common and expected finding in newborns, usually appearing within the first 2–3 days of life. It consists of small, red papules or pustules on a red base, often described as a "flea-bitten" appearance. This rash is benign and resolves on its own within a few days to weeks. It is not associated with any infection or underlying health issues.
C) Hypospadias is noted in the male newborn:
Hypospadias, a condition where the urethral opening is located on the underside of the penis rather than at the tip, is not an expected finding in all newborn males. While it occurs in a small percentage of male infants, it is a congenital anomaly that would require further assessment and possibly surgical correction. It is not considered a normal finding in a newborn.
D) Presence of syndactyly in extremities:
Syndactyly, the condition where two or more fingers or toes are fused together, is not a normal finding in newborns. While it is a congenital anomaly that can occur in some infants, it is not expected and requires further evaluation and possibly surgical intervention depending on the severity.
E) Negative Ortolani sign:
A negative Ortolani sign is an expected and normal finding in a newborn. The Ortolani maneuver is used to assess for hip dislocation, and a negative result indicates that the hip is stable and not dislocated. If the Ortolani sign were positive, it would suggest the presence of a developmental hip dysplasia, which would require further diagnostic evaluation. A negative sign is considered typical and reassuring.
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.
