A nurse is preparing to administer 250 mg of an antibiotic IM to a pregnant client for a STI. Available is 3 g/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
Volume= desired dose/available concentration per ml Available concentration per ml= 3g/5ml= 0.6g/ml
1g= 1000mg 0.6g= 600mg
Volume= 250mg/600mg per ml Volume= 0.4166ml
Therefore, the nurse should administer 0.4mls of antibiotic.

Correct Answer is C
Explanation
C. The rooting reflex is essential for breastfeeding. When the newborn's cheek or lip is stroked, the baby will turn their head toward the stimulus and open their mouth in preparation for breastfeeding. This reflex helps the newborn find the nipple and initiate feeding by latching onto it.

A. The Moro reflex, also known as the startle reflex, is triggered by a sudden noise, movement, or change in position that causes the newborn to extend their arms, arch their back, and then bring their arms back toward their body. This reflex is not directly involved in promoting newborn latching during breastfeeding. It typically occurs in response to stimuli unrelated to feeding.
B. The Babinski reflex is elicited by stroking the sole of the newborn's foot, causing the toes to fan out and the big toe to dorsiflex while the other toes spread out. This reflex is also not involved in breastfeeding and does not contribute to latching.
D. The stepping reflex occurs when the newborn is held upright with their feet touching a flat surface. The baby will make stepping movements as if walking. This reflex is unrelated to breastfeeding and does not assist in latching.
Correct Answer is D
Explanation
D. This response is appropriate for a breastfeeding mother with a family history of food allergies. Peanuts are among the common allergenic foods, and some guidelines recommend that mothers with a family history of food allergies or infants at high risk of developing allergies consider avoiding peanuts and other allergenic foods during breastfeeding. This cautious approach aims to reduce the risk of allergic sensitization in the infant.
A. Increased sleepiness alone is not a reliable indicator of a food allergy in infants. Common symptoms of a food allergy in breastfed infants include rash, hives, vomiting, diarrhea, or respiratory symptoms. Sleep patterns alone are not diagnostic of food allergies.
B. Rice cereals are generally well-tolerated and are commonly recommended as a first solid food for infants due to their hypoallergenic properties. They are not typically problematic during lactation unless the mother or infant has a specific sensitivity or allergy to rice.
C. The foods a breastfeeding mother consumes can indeed affect breast milk composition. Certain foods can transfer flavors to breast milk and may potentially cause reactions in sensitive infants. If the mother consumes allergenic foods like peanuts, cow's milk, or eggs, small amounts of allergenic proteins can pass into breast milk and potentially trigger allergic reactions in susceptible infants.
