What is the most significant risk factor for clubfoot?

Choice A reason:

Attachment phase is not one of Rubin's phases of role attachment. Rubin's theory of maternal role adaptation describes three stages that the mother goes through during the postpartum period: taking in, taking hold and letting go.

Choice B reason:

Letting go phase is the last stage of Rubin's theory of role attachment. It occurs when the mother accepts her new role and gives up her old roles. She also comes to terms with the reality of the birthing experience and the characteristics of her baby.

Choice C reason:

Taking hold phase is the second stage of Rubin's theory of role attachment. It occurs when the mother becomes interested in caring for the infant and learning about her baby and herself. She may be critical about her care-giving abilities and need positive reinforcement.

Choice D reason:

Taking in phase is the first stage of Rubin's theory of role attachment. It occurs right after the birth of the child, when the mother is passive and focused on her own needs, especially sleeping and eating. She may have limited interactions with her infant and prefer to talk about her experiences during labor, birth, and pregnancy. This matches the description of the new mother in the question, so this is the correct answer.

Choice A reason:

Diminished deep-tendon reflexes are a sign of magnesium toxicity, not safety. Magnesium sulfate is a central nervous system depressant that can cause muscle weakness, respiratory depression, and cardiac arrest if given in excess. The nurse should monitor the client's deep-tendon reflexes and stop the infusion if they are absent or reduced.

Choice B reason:

A respiratory rate of 16/min is a normal finding and indicates that the client is not experiencing respiratory depression from magnesium sulfate. The nurse should monitor the client's respiratory rate and stop the infusion if it falls below 12/min.

Choice C reason:

A heart rate of 60/min is a normal finding and indicates that the client is not experiencing bradycardia from magnesium sulfate. The nurse should monitor the client's heart rate and stop the infusion if it falls below 50/min.

Choice D reason:

Urine output of 50 mL in 4 hr is a sign of oliguria, not safety. Magnesium sulfate can cause renal impairment and fluid retention if given in excess. The nurse should monitor the client's urine output and stop the infusion if it falls below 30 mL/hr.
