A 14-year-old boy and his parents are concerned about bilateral breast enlargement. The nurse's discussion of this should be based on which statement?

Correct Answer: A

Rationale: The correct statement is that bilateral breast enlargement in a 14-year-old boy is usually benign and temporary. This condition, known as gynecomastia, is commonly seen during puberty due to hormonal changes. It typically resolves on its own without the need for intervention. It is important for the nurse to reassure the boy and his parents that this is a normal occurrence and should not be a cause for major concern. It is crucial to address any underlying anxieties and provide education on the natural course of puberty-related changes.

Correct Answer: D

Rationale: Hypospadias is a congenital condition where the opening of the urethra is located on the ventral surface of the penis instead of the tip. This results in the ventral placement of the urethral meatus compared to the normal dorsal position. It can typically be visually identified when examining the newborn's genitalia. A key characteristic of hypospadias is the abnormal positioning of the urethral opening, which distinguishes it from other conditions affecting the male genitalia.

Correct Answer: B

Rationale: Uremic frost is a term used to describe the presence of urea crystals on the skin of individuals with chronic renal failure. As kidney function declines in chronic renal failure, the body is unable to effectively excrete waste products such as urea. Urea can then be deposited on the skin when sweating, leading to the formation of white or frost-like crystals, giving the appearance of "uremic frost." This condition is a visible indicator of severe kidney dysfunction and the buildup of waste products in the body.

Correct Answer: A

Rationale: The ductus arteriosus is a fetal blood vessel that allows blood to bypass the lungs while in utero. After birth, the ductus arteriosus should close to redirect blood flow through the lungs for oxygenation. Surgical closure of the ductus arteriosus is performed to prevent the shunting of unoxygenated blood from the pulmonary artery to the aorta, therefore stopping the loss of unoxygenated blood to the systemic circulation. This helps to ensure that oxygenated blood is properly circulated to the body tissues and organs.

Correct Answer: C

Rationale: If evidence of cardiac tamponade is found in a child after heart surgery, it is crucial for the nurse to immediately report this to the physician. Cardiac tamponade is a serious condition where excess fluid or blood accumulates in the pericardial sac, compressing the heart and affecting its ability to pump effectively. Prompt recognition and intervention are essential to prevent potential life-threatening outcomes. The physician would need to assess the child's condition, consider performing procedures to relieve the tamponade such as pericardiocentesis, and provide appropriate treatment to stabilize the child. Delaying reporting and action in cases of cardiac tamponade can lead to further complications and worsen the child's condition.
