Cystic fibrosis (CF) is suspected in a toddler. Which test is essential in establishing this diagnosis?

Bronchoscopy

Serum calcium

Urine creatinine

Sweat chloride test

Answer and Explanation

The Correct Answer is D

This test measures the amount of chloride in the sweat, which is abnormally high in people with cystic fibrosis (CF). CF is an inherited disorder that affects the cells that produce mucus, sweat, and digestive juices.

Choice A is wrong because bronchoscopy is a procedure that allows the doctor to examine the airways and lungs, but it is not essential for diagnosing CF.

Choice B is wrong because serum calcium is a blood test that measures the level of calcium in the blood, which is not related to CF.

Choice C is wrong because urine creatinine is a test that measures the amount of creatinine in the urine, which reflects the kidney function, but it is not relevant to CF.

Normal ranges for sweat chloride test are:

Less than 40 millimoles per liter (mmol/L) for children and adults
Less than 30 mmol/L for infants younger than 6 months

A sweat chloride level of more than 60 mmol/L is considered positive for CF.

Correct Answer is ["A","B"]

Explanation

Pitocin and Methergine are both medications used to manage postpartum hemorrhage (PPH) by causing the uterus to contract and reduce bleeding. Pitocin is the most effective and preferred medication for PPH prevention and treatment.

Choice C is wrong because Terbutaline is a medication that relaxes the uterus and is used to stop preterm labor, not PPH.

Choice D is wrong because Hemabate is a brand name for carboprost, which is a prostaglandin that can be used for PPH, but it has more side effects and contraindications than Pitocin or Methergine.

Choice E is wrong because Magnesium sulfate is a medication that prevents seizures in women with preeclampsia or eclampsia, not PPH.

A. Weight loss B. Sleepiness or Fatigue C. Diarrhea D. Puffiness around the eyes E. Limited hair growth

Correct Answer is ["B","D"]

Explanation

Sleepiness or fatigue and puffiness around the eyes are symptoms associated with hypothyroidism. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, which regulate the body’s metabolism and energy levels.

Choice A is wrong because weight loss is more likely to occur in hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormones.

Choice C is wrong because diarrhea is also more likely to occur in hyperthyroidism, as the excess thyroid hormones speed up the digestive system.

Choice E is wrong because limited hair growth is not a specific symptom of hypothyroidism. Hair loss or thinning may occur in both hypothyroidism and hyperthyroidism, depending on the severity and duration of the condition.

Normal ranges for thyroid hormones are:

TSH: 0.4 to 4.0 mIU/L
T3: 100 to 200 ng/dL
T4: 4.5 to 11.2 mcg/dL
