1. The type of medicine that proposes that a person's inherent "life force" can foster self-healing is known as _____ medicine.
- A. homeopathic
- B. integrative
- C. naturopathic
- D. Ayurvedic
Correct answer: C
Rationale: Naturopathic medicine is based on the belief that a person's inherent "life force" can promote self-healing, often using natural therapies and lifestyle changes.
2. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?
- A. Semipermeable membranes.
- B. Hydration.
- C. Osmotic pressure.
- D. Perspiration.
Correct answer: C
Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.
3. What does a QRS Complex represent in an ECG reading?
- A. Atrial depolarization
- B. Ventricular repolarization
- C. Ventricular depolarization
- D. End of ventricular depolarization
Correct answer: C
Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.
4. Theresa, a mother with a 2-year-old daughter, asks, 'At what age can I start taking my daughter's blood pressure as a routine procedure, since hypertension is common in our family?' What would your answer be?
- A. At 2 years old, you may
- B. As early as 1 year old
- C. When she's 3 years old
- D. When she's 6 years old
Correct answer: D
Rationale: Regular blood pressure checks generally start from age 3, but in the case of a family history of hypertension, they should start when the child is around 6 years old. This is because the readings will be more reliable and indicative of the child's health condition at this age. The other options are incorrect because they suggest earlier ages for routine blood pressure checks. While blood pressure can be measured at any age, it is not typically included as part of a routine health check-up for very young children unless there are specific health concerns.
5. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?
- A. Zinc
- B. Iron
- C. Sodium
- D. Potassium
Correct answer: B
Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.
