Correct Answer: D

Rationale: The presentation described, including a well-demarcated, hyperpigmented patch with irregular borders, asymmetric color distribution, and increase in size over a short period, is concerning for melanoma. Melanoma is a type of skin cancer that arises from melanocytes, the cells that produce pigment in the skin. The irregular borders, color variation, and growth over time are classic signs of melanoma. Melanomas are potentially dangerous and should be evaluated promptly by a healthcare provider for proper diagnosis and treatment. It is important to distinguish melanoma from other benign lesions like melanocytic nevus (mole), lentigo simplex, and seborrheic keratosis, as early detection and treatment of melanoma can significantly impact patient outcomes.

Correct Answer: C

Rationale: The barrier to goal setting between the nurse and the family in this scenario is the failure of the family to perceive the existence of the problem. Goal setting in healthcare generally requires mutual agreement and understanding between the healthcare provider (nurse) and the patient/family. If the family does not perceive that there is an existing problem that needs to be addressed, there will likely be resistance or lack of motivation to set goals and work towards resolving the issue. This barrier can hinder effective communication, collaboration, and ultimately, the successful achievement of healthcare goals. It is important for the nurse to address this barrier through education, communication, and building trust to ensure that all parties are on the same page and actively participate in goal setting and care planning.

Correct Answer: C

Rationale: Nurse Minda should alert the unit staff to closely observe the fan because the occasional sparking may be a sign of an impending issue that could lead to a more serious problem. By closely monitoring the fan, the staff can ensure the safety of those in the unit and take necessary actions if the situation worsens. It is important to address potential safety hazards promptly to prevent any harm or damage.

Correct Answer: D

Rationale: Physiologic jaundice among newborn babies typically occurs between the 2nd and the 3rd day after birth. This type of jaundice is considered normal and harmless and is caused by the breakdown of red blood cells and the immaturity of the newborn baby's liver in processing bilirubin. The bilirubin levels rise in the blood, leading to a yellowish discoloration of the skin and eyes. This type of jaundice usually peaks around the 3rd to 4th day after birth and then gradually resolves without treatment within the first week of life. It is important for healthcare providers to monitor bilirubin levels and ensure that they do not reach dangerous levels that could potentially harm the newborn.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.
