1. Which organ produces and secretes bicarbonate ions and insulin?
- A. Stomach
- B. Pancreas
- C. Large intestine
- D. Small intestine
Correct answer: B: Pancreas
Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.
2. Which of the following is a factor that affects Basal Metabolic Rate (BMR)?
- A. Age
- B. Sleep
- C. Fasting/Starvation
- D. Activity Level
Correct answer: All of the above
Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.
3. A mother asks about healthy snacks for her three children under 4 years old. All are wise choices the dental hygienist can recommend, except one. Which is the exception?
- A. Low-fat milk or yogurt
- B. Whole-grain cereals
- C. Raw vegetable sticks
- D. Nuts and seeds
Correct answer: D
Rationale: Nuts and seeds pose a choking hazard for children under 4 years old, making them an unsafe snack choice for young children. While low-fat milk or yogurt, whole-grain cereals, and raw vegetable sticks are healthy snack options suitable for children under 4 years old, nuts and seeds should be avoided due to the risk of choking, especially in young children who may not have fully developed chewing abilities.
4. Myxedema coma is a life-threatening complication of long-standing and untreated hypothyroidism with one of the following characteristics.
- A. Hyperglycemia
- B. Hypothermia
- C. Hyperthermia
- D. Hypoglycemia
Correct answer: A
Rationale: Myxedema coma is associated with hypothermia, not hyperthermia. Therefore, the correct characteristic of myxedema coma is hypothermia. This condition is a medical emergency that requires prompt recognition and intervention to prevent serious complications. The presence of hyperglycemia is not a defining characteristic of myxedema coma, making choice A the correct answer in this case. Hyperthermia and hypoglycemia are not typically seen in myxedema coma and are not consistent with the clinical presentation of this condition.
5. Nurse DMLM is correct in identifying the correct sequence of events during abdominal assessment if she identifies which of the following?
- A. Inspection, Auscultation, Percussion, Palpation
- B. Inspection, Percussion, Palpation, Auscultation
- C. Inspection, Palpation, Percussion, Auscultation
- D. Inspection, Auscultation, Palpation, Percussion
Correct answer: D
Rationale: The correct sequence for abdominal assessment is Inspection, Auscultation, Percussion, Palpation. Start with Inspection to observe any visible abnormalities, followed by Auscultation to listen for bowel sounds, then Percussion to assess the density of underlying structures, and finally Palpation to feel for any tenderness or masses. Choices A, B, and C have the incorrect sequence of assessment techniques.
