Question 2

A patient is experiencing muscle cramps due to an imbalance of sodium and potassium ions. Which process is most directly responsible for maintaining the proper concentration of these ions across the cell membrane?

Accepted Answer

Active transport via the sodium-potassium pump

Question 3

Which of the following equations correctly represents the relationship between pH and hydrogen ion concentration $$[H^+]$$?

Accepted Answer

$$pH = -\log_{10} [H^+]$$

Question 4

Which of the following is a function of the integumentary system?

Accepted Answer

Regulation of body temperature

Question 5

A burn patient presents with damage to both the epidermis and the entire dermis. Which type of burn does this describe?

Accepted Answer

Third-degree burn

Question 6

Which of the following best explains why water is considered a polar molecule?

Accepted Answer

It has a partial positive charge on hydrogen and a partial negative charge on oxygen.

Question 7

Which of the following is TRUE regarding bone growth in children compared to adults?

Accepted Answer

Children have both interstitial and appositional bone growth, while adults primarily have appositional growth.

Question 8

Which of the following best describes the process of keratinization in the epidermis?

Accepted Answer

Cells in the epidermis fill with keratin, lose their nuclei, and die as they move toward the surface.

Question 9

A cell is placed in a solution with a higher concentration of solutes than inside the cell. What will happen to the cell?

Accepted Answer

It will shrink as water leaves the cell by osmosis.

Question 10

Which of the following is a correct comparison between positive and negative feedback loops in physiology?

Accepted Answer

Positive feedback amplifies the original stimulus, while negative feedback reduces it.

Question 11

Which of the following molecules is most likely to diffuse freely across a plasma membrane?

Accepted Answer

Small nonpolar molecules

Question 12

Which equation correctly represents the calculation of body mass index (BMI)?

Accepted Answer

$$BMI = \frac{weight\ (kg)}{$$height^2$$\ (m^2$)}$$

Question 13

Which of the following best describes the role of melanocytes in the skin?

Accepted Answer
