What gastrointestinal side effects are associated with antisecretory drugs such as proton pump inhibitors?
- A. Nausea and vomiting
- B. Gastroparesis
- C. Dumping syndrome
- D. Flatulence
Correct Answer: A
Rationale: Proton pump inhibitors (PPIs) are a type of antisecretory drug that can cause nausea and vomiting by altering stomach acid production. These are common side effects associated with PPIs. Gastroparesis (B) is a condition that affects the stomach muscles and prevents proper stomach emptying; it is not a side effect of PPIs. Dumping syndrome (C) is a group of symptoms that can occur after having part of your stomach removed and is not a side effect of PPIs. While some people might experience flatulence (D) when taking PPIs, it is not as commonly associated with these drugs as the effects of nausea and vomiting.

What chronic disease has been associated with increased risks of dental problems?
- A. diabetes mellitus
- B. chronic obstructive pulmonary disease
- C. Addison's disease
- D. asthma
Correct Answer: A
Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.
Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?
- A. TRUE
- B. FALSE
- C. Not applicable
- D. Not applicable
Correct Answer: A
Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.
With which of the following should fluoride supplements never be taken?
- A. Water
- B. Juice
- C. Milk
- D. Soda
Correct Answer: C
Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.
Which systolic blood pressure measurement is classified as prehypertension?
- A. 106 mmHg
- B. 119 mmHg
- C. 130 mmHg
- D. 141 mmHg
Correct Answer: B
Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.
Which condition is most closely associated with a high rate of gastroesophageal reflux disease?
- A. Pregnancy
- B. Anorexia
- C. Hypertension
- D. Diabetes mellitus
Correct Answer: A
Rationale: Pregnancy is the correct answer as it is most closely associated with a high rate of gastroesophageal reflux disease (GERD). During pregnancy, the growing fetus exerts pressure on the stomach, leading to the backflow of stomach acid into the esophagus, causing GERD. This physiological change is a common occurrence in pregnant individuals. Conversely, anorexia, hypertension, and diabetes mellitus are not typically linked to a high rate of GERD. While these conditions have their own effects on the body, they do not directly contribute to the mechanisms that cause GERD, unlike the physical changes associated with pregnancy. Therefore, choices B, C, and D are incorrect.
