Nokea
A patient presents with a well-demarcated, hyperpigmented patch with irregular borders and asymmetric color distribution on the face. The lesion has increased in size over the past few months. Which of the following conditions is most concerning for this presentation?
- A. Melanocytic nevus (mole)
- B. Lentigo simplex
- C. Seborrheic keratosis
- D. Melanoma
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.

Which of the following structures is responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates?
- A. Liver
- B. Gallbladder
- C. Salivary glands
- D. Pancreas
Correct Answer: C
Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.
What is the BEST urine sample to be used for an accurate result of pregnancy test done at home?
- A. First-voided evening urine
- B. First-voided morning urine
- C. Mid-afternoon urine sample
- D. Random urine sample
Correct Answer: B
Rationale: First-voided morning urine is the best urine sample to be used for an accurate result of a pregnancy test done at home because it is more concentrated compared to urine samples collected at other times of the day. Overnight, the hCG hormone (human chorionic gonadotropin) builds up in a woman's body, making the early morning urine more likely to contain higher levels of hCG if a woman is pregnant. The concentrated nature of first-morning urine reduces the chances of false-negative results since it provides a higher concentration of the hormone that the test is designed to detect. Therefore, using first-morning urine increases the sensitivity of the pregnancy test and improves the accuracy of the results.
Healthy physical development is dependent upon nutrition, brain development, muscle and bone. Which of the following is NOT APPROPRIATE for physical development of a pre schooler?
- A. Sleeps 6 to 8 hours of sleep each day
- B. Assists in brushing and flossing teeth
- C. Gains 5 pounds per year
- D. Eruption of the primary teeth
Correct Answer: A
Rationale: For a preschooler, it is recommended that they get more than 8 hours of sleep each day. Adequate sleep is crucial for their physical development, overall health, and cognitive function. Preschoolers typically need around 10-13 hours of sleep per day to support their growth and development. Getting less than the recommended amount of sleep can lead to issues such as behavioral problems, difficulty concentrating, and poor physical development. Therefore, ensuring that a preschooler gets enough sleep is vital for their physical well-being.
Which of the following conditions is characterized by an imbalance between bone resorption and formation, resulting in bone thinning and increased risk of fractures?
- A. Osteoarthritis
- B. Osteomyelitis
- C. Osteoporosis
- D. Osteomalacia
Correct Answer: C
Rationale: Osteoporosis is a condition characterized by an imbalance between bone resorption (breakdown of bone tissue) and bone formation, leading to bone thinning and increased risk of fractures. In osteoporosis, bones become weak and porous, making them more prone to fractures even with minor trauma. This condition is common in postmenopausal women and older individuals. Risk factors for osteoporosis include age, gender, family history, lack of physical activity, low calcium and vitamin D intake, smoking, excessive alcohol consumption, and certain medications. Treatment typically involves lifestyle modifications, including adequate calcium and vitamin D intake, weight-bearing exercises, and sometimes medication to help slow down bone loss and reduce fracture risk. Early detection and management of osteoporosis are crucial to prevent fractures and maintain bone health.
