The student nurse learns that the hormone necessary for milk production is

Choice A reason:

10% to 15% of their birth weight. This is incorrect because this range is too high for a normal newborn weight loss. Losing more than 10% of their birth weight may indicate dehydration, inadequate feeding, or other problems. • Choice B reason:

20% of their birth weight. This is incorrect because this percentage is way too high for a normal newborn weight loss. Losing 20% of their birth weight would be a serious sign of illness or malnutrition. • Choice C reason:

15% to 18% of their birth weight. This is incorrect because this range is also too high for a normal newborn weight loss. Losing 15% to 18% of their birth weight would be a cause for concern and require further evaluation. • Choice D reason:

5% to 10% of their birth weight. This is correct because this range is within the normal limits for a newborn weight loss. Newborns lose some weight as a result of insufficient caloric intake, fluid loss, and metabolic adjustments in the first week after birth. They usually regain their birth weight by the second week.

Choice A reason:

This is the best response because it shows that the nurse is providing nonpharmacological pain relief measures and supporting the client's coping mechanisms. Breathing and imagery techniques can help the client relax and focus on something other than the pain. Moaning, screaming, and vocalizing are normal and acceptable ways of expressing pain during labor, and the nurse should not try to suppress them.

Choice B reason:

This is not the best response because it does not address the husband's concern or offer any intervention for the client's pain. Asking the client to rate her pain on a scale of 0 to 10 is a subjective assessment tool that may not reflect the true intensity of her pain. Furthermore, it may be difficult for the client to answer this question while she is in the second stage of labor.

Choice C reason:

This is not the best response because it may not be feasible or appropriate to administer more pain medication to the client in the second stage of labor. The obstetrician may not be available to evaluate the client's pain, and increasing the dose of pain medication may have adverse effects on the client and the fetus, such as respiratory depression, hypotension, and decreased uterine contractility.

Choice D reason:

This is not the best response because it does not acknowledge the husband's feelings or provide any comfort or education for him. Reassuring him that his wife will be fine may sound dismissive and insensitive, and offering to stay with her while he takes a walk may imply that he is not needed or wanted in the birthing room. The nurse should involve the husband in the care of his wife and explain to him what is happening and what to expect during labor.
