Bryce is a child diagnosed with coarctation of aorta. While assessing him, Nurse Zach would expect to find which of the following?

Correct Answer: B

Rationale: Coarctation of the aorta is a congenital heart defect where there is a narrowing of the aorta, usually near the insertion of the ductus arteriosus. This narrowing can lead to decreased blood flow to the lower body. A common finding in a child with coarctation of the aorta is absent or diminished femoral pulses due to the obstruction of blood flow through the narrowed aorta. Other symptoms may include high blood pressure in the arms, weak lower body pulses, and heart murmur. Squatting posture, severe cyanosis at birth, and cyanotic ("tet") episodes are not typically associated with coarctation of the aorta.

Correct Answer: D

Rationale: The main purpose of a hearing aid is to improve the patient's ability to hear. Hearing aids are devices designed to amplify sound for individuals with hearing loss or difficulty hearing. They do not amplify background noise or musical sounds specifically; instead, they are meant to enhance the overall perception of sounds to help individuals better understand speech and communicate effectively. Moreover, hearing aids do not occlude the ear, but rather are used to transmit sound into the ear canal to make sounds louder and clearer for the wearer.

Correct Answer: A

Rationale: In the situation described, the best equipment at James' bedside to address the dislodged tracheostomy and the removal of both the inner and outer cannulas would be a new set of tracheostomy tubes and an oxygen tank.

Correct Answer: C

Rationale: A neonatal heart rate of 170 is above the normal range (90-160 bpm), which is concerning for dehydration.

Correct Answer: D

Rationale: Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when there is not enough insulin in the body. In the absence of sufficient insulin, the body is unable to use glucose for energy, leading to the breakdown of fats for fuel. This results in the excessive production of ketone bodies, specifically acetoacetate and beta-hydroxybutyrate. As the ketone bodies accumulate in the blood, they lower the blood pH, leading to acidosis. This is what causes the characteristic symptoms of DKA, such as fruity breath, deep rapid breathing, and abdominal pain. Therefore, the excessive accumulation of ketone bodies from fat metabolism is the primary cause of diabetic ketoacidosis.
