A nurse is caring for a client who is in active labor and notes the FHR baseline has been 100/min for the past 15 min.
The nurse should identify which of the following conditions as a possible cause of fetal bradycardia?
Maternal hypoglycemia.
Maternal fever.
Chorioamnionitis.
Fetal anemia.
The Correct Answer is A
The correct answer is choice a. Maternal hypoglycemia.
Choice A rationale:
Maternal hypoglycemia can lead to fetal bradycardia, causing a sustained low fetal heart rate. Hypoglycemia in the mother can affect the fetus by reducing the availability of glucose, which is essential for fetal metabolism and heart function.
-
Choice B rationale:
Maternal fever is more commonly associated with fetal tachycardia rather than bradycardia. Fever in the mother can lead to an increased fetal heart rate, not a decreased one.
-
Choice C rationale:
Chorioamnionitis is an infection of the fetal membranes and amniotic fluid, which can lead to fetal distress and tachycardia rather than bradycardia.
-
Choice D rationale:
Fetal anemia can also cause bradycardia, but in this scenario, maternal hypoglycemia is a more immediate concern as it directly affects the fetal heart rate by impacting the fetal metabolic processes.

Correct Answer is C
Explanation
Enoxaparin is a blood thinner that helps prevent the formation of blood clots in people who have certain medical conditions or who are undergoing certain procedures. Enoxaparin can increase the risk of bleeding, especially if taken with other medications that affect blood clotting, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin.
Therefore, the nurse should instruct the client to avoid taking pain relievers such as naproxen sodium (choice A), ibuprofen (choice B), or aspirin (choice D) while on enoxaparin. These pain relievers can make the client more likely to bleed when on enoxaparin. Acetaminophen (choice C) is a pain reliever that does not affect blood clotting and can be taken safely with enoxaparin. However, the client should follow the directions on the box to make sure they do not take more than the recommended amount of acetaminophen, as it can cause liver damage in high doses.
Correct Answer is C
Explanation
The correct answer is choice C. “Perform chest percussion and postural drainage at least twice daily.” This is because chest percussion and postural drainage are airway clearance techniques that help remove thick mucus from the lungs of children who have cystic fibrosis. This can prevent respiratory infections and improve lung function.
Choice A is wrong because a bronchodilator should be administered before airway clearance therapy, not after. A bronchodilator helps open up the airways and make it easier to cough up mucus.
Choice B is wrong because pancreatic enzymes should be administered with meals and snacks, not on an empty stomach.
Pancreatic enzymes help digest fats, proteins, and carbohydrates in children who have cystic fibrosis. This can prevent malnutrition and growth failure.
Choice D is wrong because there is no need to restrict gluten intake for children who have cystic fibrosis, unless they also have celiac disease.
Gluten is a protein found in wheat, barley, and rye that can cause intestinal damage in people who have celiac disease. Cystic fibrosis does not affect the ability to tolerate gluten.
