PROMETRIC EXAM QUESTIONS WITH EXPLANATION 

Q: Which of the following capsule sizes has the largest size suitable for human patient?

1. No.0
   
2. No.1
3. No.5
4. No.000

Explanation: Capsule sizes are standardized and numbered, with 000 being the largest and 5 being the smallest. A larger number indicates a smaller capsule size. Therefore, size 000 capsules are the largest size commonly used for human consumption. 

So Option 4 is the correct answer.

Q: Which of the following is the exact date for a drug to be safely taken if its expiration date is December 2018?

1. December 1,2018
2. December 15, 2018
3. December 31, 2018
4. January 1st , 2019

Explanation: Unless otherwise specified on the pack, expiration dates on medications generally mean that the medication should not be taken after the end of the month listed. In this case, since the expiration is given as "December 2018," it implies that the drug's potency and safety are not guaranteed after December 31, 2018. The expiration date on medicine indicates the last day the manufacturer guarantees its full effectiveness and safety. It's not necessarily the date the medicine becomes ineffective or unsafe, but it's the date until which the manufacturer has tested and confirmed its quality. 

 So Option 3 is the correct answer.

Q: A 2-year-old boy was found with an empty bottle of 100 chewable multivitamins. Each tablet contained 18 mg iron. He is asymptomatic at time of presentation to the emergency department. Which of the following methods of gastrointestinal decontamination would be most appropriate?

1. Gastric lavage (Gastric lavage, also known as stomach pumping, is a procedure where the stomach is emptied and cleaned using a tube inserted through the mouth or nose. It is primarily used in cases of poisoning or drug overdose.)
2. Activated Charcoal (Activated charcoal is a fine, odorless, black powder often used in emergency rooms to treat overdoses.)
3. Whole Bowel Irrigation (This involves using a special solution to flush the entire gastrointestinal tract, helping to remove iron tablets from the small intestine.) 
4. Multi-dose Activated Charcoal (Multiple-dose activated charcoal (MDAC) refers to the administration of two or more sequential doses of activated charcoal for enhanced elimination of the ingested toxin.)

Explanation: Although iron poisoning is a clinical diagnosis, serum iron levels are useful in predicting the clinical course as well as helping to guide treatment. In the treatment of iron poisoning, consider both bowel decontamination with whole bowel irrigation and chelation using intravenous deferoxamine. 

Charcoal doesn't bind to iron so option 2 and 4 are ruled out.

Gastric lavage can be used but it's not primary treatment due to its limitations (large size tablets of iron, risk of irritation of gastric mucosa especially considering the age and its not effective in removing iron if it has passed to small intestine) & availability of safer mechanisms.

WBI involves administering large volumes of a special solution (like polyethylene glycol electrolyte lavage solution) through a nasogastric tube to flush out the gastrointestinal tract. This helps to remove the unabsorbed iron tablets and reduce the risk of further absorption into the bloodstream. 

In addition to WBI, other treatments for iron poisoning may include deferoxamine, a chelating agent that binds to iron and helps eliminate it from the body.    So Option 3 is the correct answer.

Q: A physician prescribed heparin at a dose of 75 units/kg every six hours for a child weighing 15 kg, heparin is available in 2.5 ml vial containing 12,500 units. How many milliliters of heparin solution would be administered every day?

1. 0.5
2. 0.9
3. 1.5
4. 1.8

Explanation: As the child is 15kg so the total units required per dose would be 75x15=1125units. The dose has to be administered every six hours so a total of 4 doses per day and the total units to be administered per day would become 1125x4= 4500units/day.
The vial of 2.5ml have 12500 units so the ml of heparin administered from it would be 0.9ml.

So Option 2 is the correct answer.

Q:  An order for amoxicillin 500 mg three times daily for 7 days is prescribed. The pharmacy only stocks amoxicillin 250 mg capsules. Which of the following is the number of capsules the pharmacist should dispense?

1. 21
2. 42
3. 64
4. 80

Explanation: Daily dose of 500mg prescribed is 3 capsules which makes the weekly dose a total of 21 capsules. As the available capsule in stock has a strength of 250mg so the patient has to take 2 capsules at a time which will make the total capsules dispensed double i.e. 42.

So Option 2 is the correct answer.
