1. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.
- A. Both the statement and the reason are correct and related
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct answer: A
Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.
2. 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.
3. In one of your home visit to Mr. JUN, you found out that his son is sick with cholera. There is a great possibility that other member of the family will also get cholera. This possibility is a/an:
- A. Foreseeable crisis
- B. Health threat
- C. Health deficit
- D. Crisis
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. The most energy-rich nutrient is:
- A. carb
- B. fat
- C. protein
- D. water
Correct answer: B
Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.
5. What physiologic role does magnesium play in the body?
- A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
- B. Calcium homeostasis, structural integrity of heart muscle
- C. No known metabolic function, caries-preventing properties
- D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance
Correct answer: B
Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.
