Correct Answer: A

Rationale: The nurse should advise the client to use an alternative form of contraception until a new diaphragm that fits correctly post-pregnancy is obtained. It is essential to ensure proper fit for effective contraception, making it crucial to use an alternative method until the diaphragm is resized.

Correct Answer: A

Rationale: In Duchenne muscular dystrophy, a key characteristic is the progressive weakness in the lower legs, leading to a waddling, unsteady gait. The nurse should focus on teaching about this aspect as it helps in understanding the disease's progression and managing the symptoms effectively.

Correct Answer: D

Rationale: When parents report that their newborn is trying to walk, the nurse should understand that newborns exhibit a stepping reflex, which is a normal developmental response. Explaining this reflex to the parents helps them understand that it is a typical behavior seen in newborns rather than true attempts to walk. Encouraging the parents to report this to the healthcare provider (Choice A) may cause unnecessary concern since the stepping reflex is a normal part of newborn development. Acknowledging the parents' observation (Choice B) is a good communication strategy but providing education on the normal reflex is essential. Scheduling the newborn for further neurological testing (Choice C) is not indicated in this scenario as the stepping reflex is a typical finding in newborns.

Correct Answer: A

Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.

Correct Answer: B

Rationale: Changing the client's position is the priority intervention for variable decelerations as it can relieve pressure on the umbilical cord, potentially resolving the deceleration and improving fetal oxygenation. Assessing cervical dilation, administering oxygen via facemask, and turning off the oxytocin infusion are important interventions but addressing the fetal distress caused by variable decelerations takes precedence.
