A nurse is caring for an infant who has Tetralogy of Fallot and notes that the infant is easily fatigued when eating. Which defect is not present in this cardiac congenital malformation?
Overriding aorta
Pulmonary stenosis
Left ventricular hypertrophy
Ventricular septal defect
The Correct Answer is C
A. Overriding aorta: In Tetralogy of Fallot, the aorta is positioned over the ventricular septal defect (VSD), rather than solely over the left ventricle as it would be in a normal heart. This is called overriding aorta, which allows blood from both the right and left ventricles to enter the aorta.
B. Pulmonary stenosis: This is a critical component of Tetralogy of Fallot. Pulmonary stenosis refers to narrowing of the pulmonary valve or the area just below it, which restricts blood flow from the right ventricle to the pulmonary artery. This results in decreased blood flow to the lungs for oxygenation.
C. Left ventricular hypertrophy: This choice is not typically associated with Tetralogy of Fallot. Left ventricular hypertrophy refers to an enlargement or thickening of the muscular wall of the left ventricle of the heart. It is often seen in conditions where the left ventricle has to work harder to pump blood, such as in hypertension or aortic stenosis, but it is not a characteristic feature of Tetralogy of Fallot.
D. Ventricular septal defect: This defect is one of the four components of Tetralogy of Fallot. A ventricular septal defect (VSD) is a hole in the septum, the muscular wall that separates the left and right ventricles of the heart. In Tetralogy of Fallot, the VSD allows oxygen-poor blood from the right ventricle to flow directly into the left ventricle and out to the body.

Correct Answer is B
Explanation
A. "I will elevate the affected area if possible."
This statement is correct. Elevating the affected area can help reduce swelling and minimize bleeding by promoting venous return. Elevating the limb above the level of the heart can aid in controlling bleeding and is a recommended intervention.
B. "I will apply warm compresses over the site."
This statement is incorrect. Applying warm compresses is generally not recommended for controlling bleeding in hemophilia. Heat can increase blood flow to the area, potentially exacerbating bleeding. Cold compresses or ice packs are typically recommended to help constrict blood vessels and reduce bleeding.
C. "I will have my child rest."
This statement is correct. Resting is an essential component of managing bleeding episodes in children with hemophilia. Physical activity and exertion can increase the risk of injury and bleeding, so it's important for children with hemophilia to avoid strenuous activities during bleeding episodes.
D. "I will promptly mobilize the involved area to relieve pain & decrease bleeding."
Immobilizing the affected area can help control bleeding and reduce pain by minimizing movement. This is also an appropriate response.
Correct Answer is ["B","C"]
Explanation
A. "You should begin to manipulate the infant's bedtime based on the hospital's visiting hours."
This statement is incorrect. Manipulating the infant's bedtime based on hospital visiting hours may disrupt the infant's regular sleep schedule, potentially causing discomfort and distress. It's important to maintain the infant's routine as much as possible to promote comfort and well-being.
B. "You should bring the infant's favorite blanket to the hospital."
This statement is correct. Bringing the infant's favorite blanket or comfort item can provide familiarity and comfort during the hospital stay. Having familiar items from home can help soothe the infant and reduce anxiety associated with the new environment.
C. "You should read the child a story about hospitalization."
This statement is correct. Reading a story about hospitalization to the child can help prepare them for the upcoming experience and alleviate fear or anxiety. Choosing age-appropriate books that explain what to expect during a hospital stay can help normalize the experience and provide reassurance to the infant and parents.
D. "You will need to go home when it is not visiting hours."
This statement is incorrect. Parents are typically allowed to stay with their infant throughout the hospitalization, especially in the case of pediatric patients. Family presence is important for providing comfort and support to the infant and facilitating bonding during the hospital stay.
