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: A

Rationale: Beta-blockers are medications commonly used in the management of heart failure. One of the therapeutic effects of beta-blockers is to decrease the heart rate. By blocking the action of adrenaline on the heart, beta-blockers help to slow down the heart rate, reduce the workload on the heart, and improve overall heart function. In patients with heart failure, a decreased heart rate is a favorable outcome as it can help improve cardiac output and reduce symptoms of heart failure such as fatigue and shortness of breath. Monitoring the heart rate is an important assessment parameter to evaluate the effectiveness of beta-blocker therapy in patients with heart failure. Therefore, a decreased heart rate would indicate a therapeutic effect of beta-blocker therapy in this patient.

Correct Answer: C

Rationale: Introducing solid food to a three-month-old baby is considered a poor healthcare attitude as it goes against the recommended guidelines for infant feeding. The World Health Organization (WHO) and other health authorities suggest exclusive breastfeeding for the first six months of a baby's life, followed by the introduction of safe and appropriate complementary foods. Introducing solid food too early can increase the risk of food allergies, obesity, and other health issues in babies. Therefore, a young mother introducing solid food to her three-month-old baby is evidence of a poor family coping index related to healthcare attitudes.
