A two-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

Correct Answer: B

Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.

Correct Answer: A

Rationale: The best nursing intervention for a pregnant woman with hyperemesis gravidarum is to administer the prescribed IV solution. Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. Administering IV fluids helps in managing dehydration, replenishing electrolytes, and providing the necessary hydration for both the mother and the fetus. Giving oral rehydration solution (Choice B) may not be sufficient for severe cases of hyperemesis gravidarum where IV fluids are required. Encouraging small, frequent meals (Choice C) may not be effective as the woman may not be able to tolerate oral intake. Offering ginger tea (Choice D) is not the most appropriate intervention for hyperemesis gravidarum, as it may not provide adequate hydration or electrolyte balance needed in severe cases.

Correct Answer: A

Rationale: To confirm respiratory distress syndrome (RDS) in a newborn, the nurse should assess diaphragmatic breathing. In RDS, the baby may have difficulty breathing due to immature lungs, leading to shallow, rapid breathing movements. Assessing diaphragmatic breathing directly evaluates the respiratory effort and can help identify the presence of RDS. Choice B, assessing heart sounds, is not specific to diagnosing RDS but could be relevant for other conditions. Choice C, monitoring blood oxygen levels, is important but alone may not confirm RDS. Choice D, checking for signs of infection, is not a direct indicator of RDS but rather suggests a different issue.

Correct Answer: B

Rationale: When mothers smoke during pregnancy, it is associated with intrauterine growth restriction, which leads to lower birth weights in infants. Maternal smoking can restrict the flow of oxygen and nutrients to the fetus, affecting its growth and development. This can result in babies being born with lower birth weights, which can have various health implications for the newborn. Choices A, C, and D are incorrect as smoking during pregnancy is primarily linked to intrauterine growth restriction and lower birth weights in infants, rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

Correct Answer: D

Rationale: The client at 40 weeks of gestation with a 6 cm cervical dilation and a presenting part that is not engaged requires the most caution during an enema procedure. An unengaged presenting part increases the risk of cord prolapse, which can be a serious complication during the procedure. This situation demands careful attention to prevent potential complications and ensure the safety of the client and fetus. Choice A is incorrect as being in early labor does not pose the same level of risk as an unengaged presenting part. Choice B describes a client at 37 weeks with signs of early labor but does not indicate the same level of risk as an unengaged presenting part. Choice C involves a client at 1 cm cervical dilation and a 0 station with no mention of an unengaged presenting part, making it a less critical situation compared to an unengaged presentation, as in Choice D.
