Time Elapsed 40 minutes out of 40 minutes
Question 1
0 out of 1 points
A student asks for an explanation of the absolute refractory period of the action potential. What
response by the professor is best?
Answer: Inactivated voltage-gated sodium channels
Question 2
1 out of 1 points
A patient’s electrocardiogram (ECG) shows tall, peaked T waves. What lab value or assessment
,would the healthcare professional correlate with this finding?
- Hyperkalemia clinically manifests with cardiovascular changes such as bradycardia,
, hypotension, and electrocardiogram (ECG) changes that include missed P waves,
tall T waves, prolonged PR intervals, and wide QRS complexes.
Question 3
1 out of 1 points
What does the loss of the adenosine triphosphate (ATP) during ischemia cause cells to do?
- Swell because of the influx of sodium chloride (NaCl). A reduction in ATP levels causes
the plasma membrane's sodium-potassium (Na+-K+) pump and sodium-calcium
exchange to fail, which leads to an intracellular accumulation of sodium and calcium
and diffusion of potassium out of the cell. Sodium and water can then freely enter
the cell, and cellular swelling results.
Question 4
1 out of 1 points
An amniocentesis indicates a neural tube defect when an increase in which protein is evident?
- Alpha fetoprotein
, Question 5
1 out of 1 points
In somatic cell gene therapy, what type of vector is most commonly used to alter a specific set
of an individual’s somatic cells?
- Viruses
Question 6
1 out of 1 points
Physiologic pH is maintained at approximately 7.4 because bicarbonate (HCO 3) and carbonic
acid (H 2CO 3) exist in what ratio?
- 20 HCO3 to 1 H2CO3 – 20:1 ratio
Question 7
1 out of 1 points
A major determinant of the resting membrane potential necessary for the transmission of nerve
impulses is the ratio between what?
- The ratio between intracellular potassium (K+) and extracellular potassium
Question 8
1 out of 1 points
What advantage is derived from human genome sequencing on genetic disorders? (Select all
that apply.)
- Identification of the mutated gene; Diagnosis of the existing disorder; Appropriate treatment.
(The complete human genome sequence will facilitate gene identification, diagnosis, and
disease treatment.)
Question 9
1 out of 1 points
How do free radicals cause cell damage?
- Free radicals can cause damage to parts of cells such as proteins, DNA,
and cell membranes by stealing their electrons through a process called oxidation.
Question 10
1 out of 1 points
What is the difference between DNA sequence mutations and epigenetic modifications?
Question 11
1 out of 1 points
Which type of cancer is said to aggregate among families?
