A first-time father is changing the diaper of his 1-day-old daughter. He asks the nurse, "What is this black, sticky stuff in her diaper?" The nurse's best response is:

Choice A) "Oh, don't worry about that. It's okay." is incorrect because this is not a helpful or informative response for a first-time father who is changing the diaper of his 1-day-old daughter. This response does not explain what the black, sticky stuff in the diaper is, why it is there, or how long it will last. It also does not address the father's concern or curiosity, and may make him feel dismissed or ignored. Therefore, this response is inadequate and inappropriate.

Choice B) "That's meconium, which is your baby's first stool. It's normal." is correct because this is a clear and accurate response for a first-time father who is changing the diaper of his 1-day-old daughter. This response explains what the black, sticky stuff in the diaper is, which is meconium. Meconium is a substance that consists of amniotic fluid, mucus, bile, and other waste products that accumulate in the baby's intestines before birth. It is usually passed within the first 24 to 48 hours after birth, and then replaced by transitional or regular stools. Meconium has a dark green or black color and a thick, sticky consistency. It does not have any odor or bacteria. It is normal and harmless for most babies, unless they inhale it during delivery, which can cause breathing problems or infection. Therefore, this response reassures and educates the father about his baby's condition.

Choice C) "That's transitional stool." is incorrect because this is not a true or complete response for a first-time father who is changing the diaper of his 1-day-old daughter. This response does not identify what the black, sticky stuff in the diaper is, which is meconium. Transitional stool is a type of stool that appears after meconium and before regular stools. It usually occurs between the second and fifth day after birth, and then changes to yellow or brown stools. Transitional stool has a greenish-brown color and a loose, seedy consistency. It may have some odor or bacteria. It indicates that the baby's digestive system is maturing and adapting to breast milk or formula. Therefore, this response confuses and misleads the father about his baby's condition.

Choice D) "That means your baby is bleeding internally." is incorrect because this is not a valid or appropriate response for a first-time father who is changing the diaper of his 1-day-old daughter. This response does not describe what the black, sticky stuff in the diaper is, which is meconium. Bleeding internally means that blood vessels are damaged or ruptured inside the body, causing blood loss and shock. This can be caused by various factors such as trauma, infection, clotting disorder, or medication. Bleeding internally can manifest as blood in the stool, urine, vomit, or saliva. However, it does not cause black, sticky stools like meconium. Moreover, this response scares and alarms the father without any evidence or reason. Therefore, this response is false and unethical.

Choice A) Wrap the cord loosely with a sterile towel saturated with warm normal saline: This is not an appropriate action because it does not relieve the compression of the cord, which can cause fetal hypoxia and acidosis. The cord should be kept moist, but not wrapped around anything.

Choice B) Place a sterile gloved hand into the vagina and hold the presenting part off the cord while calling for assistance: This is the correct action because it prevents further descent of the fetus and reduces the pressure on the cord, which can improve fetal oxygenation and blood flow. The nurse should also elevate the woman's hips and place her in a knee-chest or Trendelenburg position to reduce gravity. The nurse should call for immediate assistance and prepare for an emergency cesarean section.

Choice C) Increase the IV drip rate: This is not an appropriate action because it does not address the cause of the variable decelerations, which is cord compression. Increasing the IV fluid may cause fluid overload and worsen maternal and fetal outcomes.

Choice D) Administer oxygen to the woman via mask at 8 to 10 L/minute: This is not an appropriate action because it does not relieve the cord compression, which is the main threat to fetal well-being. Oxygen administration may be helpful in some cases of fetal distress, but it is not sufficient in this situation.
