質問 21
A 67-year-old female presents to your clinic complaining of fatigue, diarrhea, headaches and a loss of appetite.
Upon examination you find that she is having some cognitive difficulty. Laboratory results reveal: MCV: 109fL; Hgb: 9g/dL; MMA and homocystine are both elevated. Shilling test is positive.
What is the next best step in the management of this patient?

  • A. Give corticosteroids and iron supplementation
  • B. Lifelong Vitamin B12 supplementation
  • C. Iron supplementation for 4-6 months
  • D. Lifelong folic acid supplementation
  • E. Obtain a Coomb's test

正解: B

解説:
Lifelong Vitamin B12 supplementation. Vitamin B12 (cyanocobalamin) deficiency generally presents in patients as fatigue, diarrhea and headaches but can also be the cause of cognitive changes (difficulty concentrating, even mild dementia). Pernicious anemia is a macrocytic anemia, therefore laboratory findings indicate an increased mean corpuscular volume (MCV), with a decreased hemoglobin. A positive Schilling test indicates that the B12 deficiency is due to a lack of intrinsic factor. Lifelong cyanocobalamin supplementation (either orally or via injections) is needed to treat pernicious anemia. A is incorrect. Folic acid deficiency anemia is another common type of macrocytic anemia. However, cognitive deficits are not typically seen with folic acid deficiency. Furthermore, a schilling test would be negative and the methylmalonic acid (MMA) would be normal, rather than elevated. C is incorrect. Iron deficiency anemia causes a microcytic anemia, characterized by a decreased MCV. D is incorrect. A Coomb's test is used to detect autoimmune hemolysis that may be suspected in patients with normocytic anemia (anemia with an MCV in the normal range). E is incorrect.
Corticosteroids and iron supplementation are indicated as treatment in hemolytic anemia.

 

質問 22
You receive an order for 40mg/kg/dose of Amoxicillin every 12 hours. Pt's weight is 18 lbs. You have
250mg/5ml of amoxicillin suspension.
Calculate the total amount in milliliters needed for 10-day supply. Round up your answer to the nearest 1.

  • A. 96 mls
  • B. 14 mls
  • C. 132 mls
  • D. 36 mls
  • E. 86 mls

正解: C

解説:
Explanation
If 40mg of amoxicillin are needed per kg of body weight, then the dose of amoxicillin is 40mg multiplied by the patient's body weight. This patient weighs 18 lbs, based on the conversion of 2.2 lbs = 1 kg, the patient weighs
8.2 kg. 40 mg multiplied by 8.2 kg is equal to 328 mg, this is one dose of amoxicillin. If the amoxicillin comes in 250 mg/5 mL, then it needs to be determined how many mLs it will take to get 328 mg of amoxicillin. In order to do this 328 mg needs to be divided by 250 mg to get a ratio. This comes out to be 1.312. This ratio can be multiplied by the number of mLs it takes to make up 250 mg, which is 5 mLs. 1.312 multiplied by 5 mLs is 6.56 mL, this is how many mLs it will take to have 328 mg. This volume is for 1 single dose of amoxicillin. The patient is receiving 2 doses per day and for a total of 10 days, this means the patient will be receiving 20 doses. 20 doses multiplied by 6.56 mL doses equals the total volume the patient will be receiving, which is
131.2 mL.

質問 37
Which of the following class of antidiabetic medications can increase triglycerides?

  • A. Thiazolidinediones
  • B. Alpha-glucosidase inhibitors
  • C. Bile acid sequestrant
  • D. SGLT2 Inhibitor
  • E. GLP-1 agonist

正解: C

解説:
Explanation
The only bile acid sequestrant, colesevelam (Welchol), has been shown to increase triglycerides through mechanism of: activation of phosphatidic acid phosphatase with promotes triglyceride synthesis. GLP-1 agonists work on GLP 1 receptors to increase insulin secretion, decrease glucagon secretion, and increase satiety. Thiazolidinediones activate nuclear transcription factor PPAR gamma to increase insulin sensitivity.
SGLT2 inhibitors inhibit glucose reabsorption in the kidney. Alpha-glucosidase inhibitors slow down digestion and absorptions of carbs in the gut.
