A nurse is providing discharge teaching to the parents of a toddler who has cystic fibrosis.

Which of the following instructions should the nurse include?

“Use a nebulizer to administer a bronchodilator following airway clearance therapy.”.

“Administer pancreatic enzymes on an empty stomach.”.

“Perform chest percussion and postural drainage at least twice daily.”.

“Restrict intake of foods that contain gluten.”.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

, dizziness.

Dizziness is a manifestation of hypovolemia, which is a decrease in blood volume due to fluid loss.

Hypovolemia can cause orthostatic hypotension, which is a drop in blood pressure when changing positions. This can lead to dizziness, lightheadedness, or fainting.

Choice A, epistaxis, is wrong because it is not a sign of hypovolemia, but rather a possible cause of it. Epistaxis is a nosebleed that can result from trauma, infection, dryness, or coagulation disorders.

Choice B, headache, is wrong because it is not a specific sign of hypovolemia, but rather a nonspecific symptom that can have many causes. Headache can be associated with dehydration, but it can also be caused by stress, infection, inflammation, or other factors.

Choice D, shortness of breath, is wrong because it is not a sign of hypovolemia, but rather a sign of fluid volume excess.

Fluid volume excess is an increase in blood volume due to fluid retention or overload. Fluid volume excess can cause dyspnea, which is difficulty breathing or shortness of breath.

Normal ranges for blood pressure are 90/60 mm Hg to 120/80 mm Hg for adults.

Normal ranges for heart rate are 60 to 100 beats per minute for adults.

A. Maternal hypoglycemia. B. Maternal fever. C. Chorioamnionitis. D. Fetal anemia.

Correct Answer is A

Explanation

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.
