Which clinical manifestation, when found in newborns, may indicate the presence of cystic fibrosis?
Meconium ileus
Cyanosis
Yellow, seedy, loose stools
Coughing
The Correct Answer is A
A. Meconium ileus is a common early sign of cystic fibrosis in newborns. It occurs when the meconium, which is the first stool of a newborn, becomes thick and sticky, leading to a blockage in the intestines. This is often one of the first signs of cystic fibrosis in infants.
B. Cyanosis, while indicative of oxygenation problems, is not a specific sign of cystic fibrosis in newborns. It may be seen in many respiratory or cardiac conditions.
C. Yellow, seedy, loose stools are more commonly associated with normal newborn digestion or conditions like lactose intolerance or gastrointestinal infections, not specifically cystic fibrosis.
D. Coughing is a symptom of cystic fibrosis, but it typically develops later as the disease progresses and affects the lungs, rather than being an early sign in newborns.

Correct Answer is D
Explanation
A. Osteoclasts are responsible for bone resorption, not formation. Increased osteoclast activity leads to excessive bone breakdown, not enhanced formation.
B. Osteoblasts are responsible for bone formation. In osteoporosis, osteoblast activity is not increased; rather, it is osteoclast activity that is dysregulated, leading to bone loss.
C. Enhanced bone formation is typically seen in conditions like osteopetrosis or during bone healing. Osteoporosis is characterized by an imbalance in favor of bone resorption, not formation.
D. Osteoporosis is characterized by increased bone resorption, which is primarily driven by osteoclast activity. This leads to a decrease in bone density and an increased risk of fractures.
Correct Answer is A
Explanation
A. Dehydration increases the risk of renal calculi (kidney stones) because it leads to concentrated urine, which promotes the formation of stones. When there is insufficient fluid intake, the kidneys cannot dilute substances like calcium and oxalate, which can form crystals and eventually stones.
B. A sedentary lifestyle is a risk factor for a variety of health issues, including obesity, but it does not directly increase the risk of kidney stones. Physical inactivity can contribute to weight gain, which in turn may increase the risk of developing stones, but it is not as direct a cause as dehydration.
C. Drinking 32 ounces of milk per day does not directly increase the risk for kidney stones. In fact, moderate calcium intake can help prevent the formation of certain types of kidney stones. However, excessive calcium intake from supplements (rather than food) may increase the risk.
D. Running 5 miles does not increase the risk of kidney stones. In fact, regular physical activity can help prevent the formation of kidney stones by promoting overall health and hydration.
