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 C
Explanation
A) Goodell’s sign:
Goodell's sign refers to the softening of the cervix that occurs early in pregnancy, typically around 4–6 weeks. It is a probable sign of pregnancy due to increased vascularity and hormonal changes. However, it does not describe the movement of the fetus or the sensation felt by the provider when pressure is applied to the cervix.
B) Lightening:
Lightening refers to the sensation of the fetus dropping or descending into the pelvic cavity, which typically happens in the later stages of pregnancy (around 36 weeks or later). It is not related to the fetal movement felt by the provider through upward pressure on the cervix, but rather to the physical repositioning of the fetus as it prepares for labor.
C) Ballottement:
Ballottement is the correct term for the movement of the fetus that can be felt by the provider when upward pressure is applied to the cervix. This technique involves a gentle tapping or pushing on the cervix, causing the fetus to rise and then "bounce" back. This is a probable sign of pregnancy, typically noticeable between 16 and 18 weeks gestation.
D) Chadwick's sign:
Chadwick’s sign refers to the bluish discoloration of the cervix, vagina, and vulva due to increased blood flow and is often an early sign of pregnancy. It does not relate to the movement of the fetus felt by the provider, but rather to changes in the color of the genital tissues.
Correct Answer is D
Explanation
A) Sublimation:
Sublimation refers to a defense mechanism where a person redirects potentially negative emotions or impulses into socially acceptable behaviors or activities. While this is a psychological concept, it does not apply to the father’s behavior immediately after birth. The father's actions, such as gazing at his baby and bonding, are not a result of sublimation but rather a normal part of bonding and attachment.
B) Claiming:
Claiming refers to the process where parents identify specific traits or characteristics in their newborn that they feel emotionally connected to, such as "He has my eyes" or "She has your nose." While the father might be engaging in claiming behaviors as he bonds with his baby, this term is more focused on recognizing physical attributes, rather than the intense emotional connection and captivation that is reflected in the scenario.
C) Mutuality:
Mutuality involves the reciprocal relationship between the newborn and the parents, where both give and receive emotional responses. It develops as the baby and parent interact, such as through eye contact, touch, and vocalizations. However, mutuality is a broader, ongoing process, while the father's behavior in this instance reflects a more specific emotional attachment and admiration, which aligns more closely with engrossment.
D) Engrossment:
Engrossment refers to the intense fascination and preoccupation that a parent, especially a father, feels toward their newborn. This process is characterized by behaviors such as gazing at the baby, holding them closely, and being captivated by their every movement. The father’s behavior in this scenario—staring into his baby’s eyes and showing deep emotional engagement—fits the definition of engrossment, which is a common and normal part of the bonding process immediately after birth.
