Which structural defects constitute tetralogy of Fallot?
A. Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy.
Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy. This choice is incorrect because it includes "aortic hypertrophy" and "left ventricular hypertrophy," which are not components of the tetralogy of Fallot. Aortic hypertrophy is not a recognized structural defect in tetralogy of Fallot, and left ventricular hypertrophy is not a characteristic feature of this congenital heart condition.
B. Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This is the correct choice. Tetralogy of Fallot is characterized by four specific structural defects: pulmonic stenosis (narrowing of the pulmonary valve), ventricular septal defect (hole between the right and left ventricles), overriding aorta (aorta positioned over the ventricular septal defect, receiving blood from both ventricles), and right ventricular hypertrophy (enlargement of the right ventricle due to increased workload).
C. Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This choice is incorrect because it includes "aortic stenosis," which is not part of the tetralogy of Fallot. In tetralogy of Fallot, the stenosis occurs at the pulmonary valve, not the aortic valve.
D. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy.
Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy. This choice is incorrect. While "overriding aorta" is present in tetralogy of Fallot, "atrial septal defect" and "left ventricular hypertrophy" are not part of this condition. Atrial septal defects involve a hole between the two atria, not the ventricles, and left ventricular hypertrophy is not typically seen in tetralogy of Fallot.

Full Explanation
The correct answer is choice B: Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Choice A rationale:
Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy. This choice is incorrect because it includes "aortic hypertrophy" and "left ventricular hypertrophy," which are not components of the tetralogy of Fallot. Aortic hypertrophy is not a recognized structural defect in tetralogy of Fallot, and left ventricular hypertrophy is not a characteristic feature of this congenital heart condition.
Choice B rationale:
Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This is the correct choice. Tetralogy of Fallot is characterized by four specific structural defects: pulmonic stenosis (narrowing of the pulmonary valve), ventricular septal defect (hole between the right and left ventricles), overriding aorta (aorta positioned over the ventricular septal defect, receiving blood from both ventricles), and right ventricular hypertrophy (enlargement of the right ventricle due to increased workload).
Choice C rationale:
Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This choice is incorrect because it includes "aortic stenosis," which is not part of the tetralogy of Fallot. In tetralogy of Fallot, the stenosis occurs at the pulmonary valve, not the aortic valve.
Choice D rationale:
Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy. This choice is incorrect. While "overriding aorta" is present in tetralogy of Fallot, "atrial septal defect" and "left ventricular hypertrophy" are not part of this condition. Atrial septal defects involve a hole between the two atria, not the ventricles, and left ventricular hypertrophy is not typically seen in tetralogy of Fallot.

The nurse is caring for a school-age girl who has had a cardiac catheterization. The child tells the nurse that her bandage is "too wet." The nurse finds the bandage and bed soaked with blood. What is the most appropriate initial nursing action?
A. Place the child in the Trendelenburg position.
is wrong because placing the child in the Trendelenburg position is not an appropriate initial nursing action in this scenario. This position can increase intracranial pressure and is typically used for patients experiencing shock or hypotension.
B. Apply a new bandage with more pressure.
is wrong because applying a new bandage with more pressure might be a subsequent action, but the priority is to apply direct pressure to slow down the bleeding.
C. Notify the physician.
is wrong because notifying the physician is important, but the nurse should first take immediate action to control the bleeding and minimize potential harm to the patient.
D. Apply direct pressure above the catheterization site.
The first action should be to apply direct pressure above the catheterization site to help control the bleeding and minimize blood loss. This will also give the nurse time to prepare additional interventions or supplies if necessary.

Pancreatic enzymes are administered to the child with cystic fibrosis. What information should be included in patient education concerning the administration of these enzymes?
A. Administer pancreatic enzymes between meals if at all possible.
Administer pancreatic enzymes between meals if at all possible. This is the correct choice. When educating the parents and child with cystic fibrosis about the administration of pancreatic enzymes, it's important to emphasize that these enzymes should be given between meals whenever feasible. Administering them between meals, when the stomach is less acidic and less likely to release the enzymes prematurely, ensures optimal digestion of food and absorption of nutrients. This approach aligns with the physiological need to supplement pancreatic enzyme function due to the inadequate natural enzyme production in cystic fibrosis.
B. Pancreatic enzymes can be swallowed whole or sprinkled on a small amount of food taken at the beginning of a meal.
Pancreatic enzymes can be swallowed whole or sprinkled on a small amount of food taken at the beginning of a meal. This choice is a valid option for administering pancreatic enzymes. While it's true that the enzymes can be taken either by swallowing the capsules whole or by opening them and sprinkling the contents on a small amount of food at the start of a meal, this method can vary based on individual preferences and abilities. However, the primary focus should be on timing (between meals) to achieve the best enzymatic action.
C. Do not administer pancreatic enzymes if the child is receiving antibiotics.
Do not administer pancreatic enzymes if the child is receiving antibiotics. This statement is not accurate. There is no general contraindication to administering pancreatic enzymes while a child is on antibiotics. However, it's important for the healthcare provider to be aware of all the medications the child is taking to ensure there are no potential drug interactions or effects on absorption. Always consult with the healthcare team before adjusting the administration of any medication.
D. Decrease the dose of pancreatic enzymes if the child is having frequent, bulky stools.
Decrease the dose of pancreatic enzymes if the child is having frequent, bulky stools. This statement is not consistent with typical practice. If a child is experiencing frequent, bulky stools, it may actually indicate that the pancreatic enzyme dosage needs adjustment (increasing the dose rather than decreasing). Bulky stools can suggest poor digestion and absorption, which might require more enzymes to properly break down nutrients. Dosage adjustments should always be made under the guidance of the healthcare provider based on factors such as stool consistency, weight gain, and nutritional status.

Which action by the school nurse is important in the prevention of rheumatic fever?
A. Recommend salicylates instead of acetaminophen for minor discomforts.
Recommending salicylates instead of acetaminophen for minor discomforts is not relevant to the prevention of rheumatic fever. Rheumatic fever is primarily associated with untreated streptococcal infections, particularly streptococcal pharyngitis (strep throat), which can lead to complications such as rheumatic fever if left untreated. The choice of pain relievers like salicylates or acetaminophen doesn't play a significant role in preventing rheumatic fever.
B. Encourage routine cholesterol screenings.
Encouraging routine cholesterol screenings is not relevant to the prevention of rheumatic fever. Rheumatic fever is an immune-mediated inflammatory response to certain strains of Streptococcus bacteria, particularly Streptococcus pyogenes. Cholesterol screenings are more related to assessing cardiovascular risk and are not directly linked to preventing rheumatic fever.
C. Conduct routine blood pressure screenings.
Conducting routine blood pressure screenings is not directly related to the prevention of rheumatic fever. Blood pressure screenings are important for identifying hypertension and other cardiovascular risk factors, but they do not have a direct impact on preventing rheumatic fever, which is primarily a complication of untreated streptococcal infections.
D. Refer children with sore throats for throat cultures.
Refer children with sore throats for throat cultures. This is the correct choice. Rheumatic fever often develops as a result of untreated streptococcal pharyngitis (strep throat). Throat cultures are crucial for diagnosing streptococcal infections and determining the appropriate course of treatment with antibiotics. By identifying and treating streptococcal infections promptly, the risk of developing rheumatic fever can be significantly reduced.
