Hemangiomas are the most common benign tumors of infancy, occurring more in full-term infants. Of the following, the most common risk factor of development of hemangioma is

Correct Answer: B

Rationale: Female infants are at higher risk for developing hemangiomas.

Correct Answer: A

Rationale: Vitamin K plays a crucial role in the production of clotting factors in the liver. Patients undergoing a splenectomy may be at an increased risk of bleeding during and after surgery due to the decreased availability of these clotting factors. Administering Vitamin K before the surgery helps to correct any potential clotting problems, ensuring proper hemostasis and reducing the risk of excessive bleeding during the procedure. This preoperative intervention can help optimize the patient's coagulation status and improve their outcomes postoperatively.

Correct Answer: A

Rationale: The sympathetic nervous system is responsible for the body's "fight or flight" response. Tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation during times of stress or danger. These physiological responses prepare the body for action, such as running away from a threat.

Correct Answer: C

Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heart rhythms. One of the therapeutic effects of digoxin is an improvement in cardiac output, leading to better tissue perfusion. As the heart's pumping ability improves, blood flow to the kidneys also increases, resulting in an increase in urine output. Therefore, an increase in urine output is a positive indication that digoxin is effective for the patient. Monitoring urine output can be a valuable way for nurses to assess the response to digoxin therapy and the overall cardiac function of the patient.

Correct Answer: B

Rationale: A nursing intervention to promote parent-newborn attachment should include explaining individual differences among newborns to the parents. This is important because understanding a newborn's unique characteristics, behaviors, and needs can help parents feel more confident and responsive in caring for their baby. By educating parents about individual differences, nurses can empower them to create a strong bond with their newborn and provide appropriate care based on the baby's specific cues and signals. This can lead to a positive and nurturing parent-newborn relationship, which is crucial for the baby's development and well-being.
