EE Chapter 02 Gastrointestinal System Q&A (1 OF 39) Sample Questions
1. Deficiency of parietal cell can cause?
- A. Deficiency of vitamin D
- B. Deficiency of vitamin K
- C. Achlorhydric
- D. Chlorhydric
Tips: Parietal cell produces HCL and intrinsic factors. Achlorhydria or hypochlorhydria refers to states where the production of hydrochloric acid in gastric secretions of the stomach and other digestive organs is absent or low, respectively.
Strategic thinking: in answering this type of question:
1. Read the question.
2. Make an association of the function of the cells, in this case parietal, with what is expected to happen if the body has less of these. As discussed from the TIPS, parietal cells play a major role in the stomach’s acidity.
3. Choose the option that describes a condition of low acidity, as this is the consequence of decreased parietal cells.
(Refer from your Misbah’s Evaluating review book the cells that play an important function in the normal physiology of the body system they belong. Knowing these would help you determine the consequences in cases where there is either deficiency or excess of these. In addition, note the surgical alteration/removal of the organs that secrete these cells as this will largely aid you analyze problems expected to arise when a patient is under medication. Example: Gastrectromy: partial or complete removal of the stomach. Patient is taking an antifungal, (i.e. Ketoconazole) which requires acidic environment for optimal absorption. )
