A client is diagnosed with an atrial septal defect (ASD).
What is a likely symptom associated with this condition?

Prepare for emergency surgery.

Choice A rationale:

Administer oxygen therapy immediately.

Administering oxygen therapy would provide temporary relief to the patient's cyanosis, but it does not address the underlying issue in Tetralogy of Fallot (TOF).

TOF is a congenital heart defect characterized by a combination of four heart abnormalities, one of which is a ventricular septal defect (VSD) that allows oxygen-poor blood to mix with oxygen-rich blood.

Administering oxygen will increase the oxygen saturation in the blood but will not fix the structural problem.

The immediate priority for a patient with TOF experiencing a hypercyanotic spell is to address the heart defect itself.

Choice B rationale:

Prepare for emergency surgery.

In Tetralogy of Fallot, hypercyanotic spells, also known as "tet spells," are a medical emergency.

These spells occur due to a sudden decrease in systemic vascular resistance, causing more blood to flow into the right ventricle, leading to increased right-to-left shunting, further decreasing oxygenation.

The most appropriate intervention is to prepare for emergency surgery to correct the underlying cardiac defects, such as closing the VSD and relieving right ventricular outflow obstruction.

Surgery is the definitive treatment for TOF and should be performed promptly during a tet spell to prevent severe hypoxia and potential long-term complications.

Choice C rationale:

Monitor vital signs closely.

While monitoring vital signs is essential in the care of a patient with TOF, it is not the most immediate response in the scenario of a hypercyanotic spell.

Monitoring alone will not address the critical need for intervention to improve oxygenation and prevent hypoxia.

Choice D rationale:

Administer prescribed medication.

Administering prescribed medication may be part of the overall management of a patient with TOF, but it is not the immediate response during a hypercyanotic spell.

Medications can help manage symptoms and stabilize the patient, but the definitive treatment for TOF is surgical correction.

"This murmur is a sign of a heart defect called coarctation of the aorta (COA).”.

Choice A rationale:

"This murmur is a sign of a heart defect called coarctation of the aorta (COA).”.

A systolic ejection murmur heard at the left upper sternal border can be indicative of coarctation of the aorta (COA).

Coarctation of the aorta is a congenital heart defect characterized by a narrowing or constriction of the aorta, typically near the site of the ductus arteriosus.

This narrowing leads to increased pressure and turbulence in the left ventricle and aorta, resulting in the systolic ejection murmur.

Informing the client about the likely diagnosis is a good approach as it helps provide them with essential information about their condition.

Choice B rationale:

"This murmur is a sign of a heart defect called atrial septal defect (ASD).”.

An atrial septal defect (ASD) typically presents with a different type of murmur, not a systolic ejection murmur heard at the left upper sternal border.

ASD is characterized by a fixed, split second heart sound (S2) and a mid-systolic murmur at the upper left sternal border.

The description in the question does not align with the typical findings of an ASD.

Choice C rationale:

"This murmur is a sign of a heart defect called ventricular septal defect (VSD).”.

A ventricular septal defect (VSD) also presents with a different type of murmur, typically a harsh holosystolic murmur heard at the lower left sternal border.

The description of the murmur in the question, a systolic ejection murmur at the left upper sternal border, is not characteristic of a VSD.

Choice D rationale:

"This murmur is a sign of a heart defect called tetralogy of Fallot (TOF).”.

Tetralogy of Fallot (TOF) is characterized by a different set of heart defects, including a ventricular septal defect (VSD), overriding aorta, right ventricular outflow tract obstruction, and right ventricular hypertrophy.

The murmur described in the question is not specific to TOF and is more indicative of coarctation of the aorta (COA) due to its location and characteristics.
