Anatomy

1. Bradycardia refers to a heart rate that is:

Correct answer: D

Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.

2. What is the SI unit of measurement for momentum?

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).

3. Which hormone, produced by the adrenal glands, prepares the body for a "fight or flight" response by increasing heart rate, dilating airways, and mobilizing energy stores?

Correct answer: c

Rationale: The correct answer is C: Epinephrine. Epinephrine, also known as adrenaline, is the hormone produced by the adrenal glands that prepares the body for a 'fight or flight' response. It increases heart rate to pump more blood to muscles, dilates airways to improve oxygen intake, and mobilizes energy stores to provide immediate fuel for physical activity. Cortisol is a hormone involved in stress response and metabolism regulation, but it does not directly trigger the rapid physiological changes associated with 'fight or flight.' Aldosterone regulates salt and water balance, while insulin regulates blood sugar levels, neither of which are directly involved in preparing the body for a rapid response to danger or stress.

4. Which of the following is NOT a function of the integumentary system?

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

5. A lab report shows a potassium level of 4.5 millimoles per liter (mmol/L). Is this within the normal range of 3.5 to 5.3 mmol/L?

Correct answer: B

Rationale: The potassium level of 4.5 mmol/L falls within the normal range provided (3.5 to 5.3 mmol/L). 5. An infant's feeding schedule prescribes 120 milliliters of formula every 3 hours. How many ounces of formula should be prepared for a 24-hour period?

6. Functional nursing has some advantages, which one is an EXCEPTION?

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.
