A nurse is educating a family about bleeding disorders while they await the results of their child's laboratory testing. Which of the following statements accurately describes the differences in the causes of hemophilia A, hemophilia B, and von Willebrand disease? (Select All that Apply.)
Hemophilia A is a result of insufficient or absent factor VIII.
Von Willebrand disease is a disorder that occurs because of excess production of von Willebrand Factor.
Hemophilia B results from insufficient or absent factor IX.
Von Willebrand disease is a disorder that occurs because of absent or insufficient von Willebrand Factor.
Hemophilia A is a result of insufficient or absent fibrinogen.
Correct Answer : A,C,D
A. Hemophilia A is a result of insufficient or absent factor VIII is correct. Hemophilia A is caused by a deficiency or absence of clotting factor VIII, which impairs the ability of blood to clot properly.
B. Von Willebrand disease is a disorder that occurs because of excess production of von Willebrand Factor is incorrect. Von Willebrand disease is actually caused by a deficiency or dysfunction of von Willebrand Factor, which is necessary for platelet adhesion and clotting.
C. Hemophilia B results from insufficient or absent factor IX is correct. Hemophilia B is caused by a deficiency of clotting factor IX, similar to hemophilia A, but involves a different clotting factor.
D. Von Willebrand disease is a disorder that occurs because of absent or insufficient von Willebrand Factor is correct. This disorder involves a deficiency or dysfunction of von Willebrand Factor, which leads to impaired clotting and easy bleeding.
E. Hemophilia A is a result of insufficient or absent fibrinogen is incorrect. Hemophilia A is caused by a deficiency of factor VIII, not fibrinogen, which is involved in the final steps of the clotting cascade.

Correct Answer is C
Explanation
A. White rice is typically recommended during diarrhea as it is easy to digest and helps bind stools. It is part of the BRAT diet (bananas, rice, applesauce, toast), which is often advised during gastrointestinal upset.
B. Applesauce is also commonly recommended as part of the BRAT diet during diarrhea. It is gentle on the stomach and can help firm up stools.
C. Fruit juice should be avoided during diarrhea. It contains high levels of sugar and can worsen diarrhea by increasing the osmotic load in the intestines, potentially leading to more fluid loss.
D. Bananas are a good option during diarrhea as they are gentle on the stomach, provide potassium, and help bind stools. They are also part of the BRAT diet, which is often recommended for children with diarrhea.
Correct Answer is C
Explanation
A. Keep the infant supine is incorrect. After cleft palate repair, it is generally recommended to keep the infant in a position that minimizes pressure on the surgical site. Keeping the infant in a supine position may cause pressure on the repaired area, so side or semi-prone positioning is preferred.
B. Suction the mouth with an oral suction tube is incorrect. Suctioning should be avoided unless absolutely necessary because it can irritate the surgical site and cause trauma to the newly repaired palate.
C. Apply elbow restraints and release them periodically is correct. Elbow restraints are commonly used after cleft palate surgery to prevent the infant from touching or putting pressure on the surgical site. These restraints should be periodically released to allow for movement and prevent skin breakdown.
D. Feed the infant with a spoon for 48 hours is incorrect. After cleft palate repair, feeding should be done carefully. Special feeding bottles or cups are typically used to avoid trauma to the surgical site. Feeding with a spoon may cause pressure on the repair and should be avoided.
