Question 1 of 5
What is the main function of the mitochondria in a cell?
Correct Answer: A
Rationale: The correct answer is A:
To produce energy in the form of ATP. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This energy is essential for various cellular activities.
Choice B is incorrect because protein synthesis primarily occurs in the ribosomes.
Choice C is incorrect as the genetic information is stored in the cell's nucleus.
Choice D is incorrect as the regulation of cell growth involves various other organelles and processes within the cell.
Question 2 of 5
A patient is prescribed acyclovir (Zovirax) for the treatment of genital herpes. What is the expected outcome of this medication?
Correct Answer: C
Rationale: The expected outcome of acyclovir (Zovirax) for the treatment of genital herpes is decreased viral shedding. Acyclovir is an antiviral medication that works by inhibiting the replication of the herpes virus, thereby reducing viral shedding and helping to control outbreaks.
Choice A, decreased testosterone production, and
Choice B, decreased libido, are unrelated outcomes of acyclovir treatment for genital herpes.
Choice D, decreased bacterial replication, is also incorrect as acyclovir specifically targets viruses and does not affect bacterial replication.
Question 3 of 5
When a healthcare professional notices that a patient has type O blood, they realize that anti-_____ antibodies are present in the patient's body.
Correct Answer: C
Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens.
Therefore, the correct answer is C.
Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies.
Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.
Question 4 of 5
A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse monitor during this therapy?
Correct Answer: A
Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events like heart attacks and strokes, especially in older patients.
Choice B, increased risk of liver dysfunction, is not a common adverse effect of testosterone therapy.
Choice C, increased risk of prostate cancer, is a concern when using testosterone therapy in patients with existing prostate cancer, but not a general adverse effect.
Choice D, increased risk of bone fractures, is not typically associated with testosterone therapy.
Question 5 of 5
A woman with severe visual and auditory deficits is able to identify individuals by running her fingers lightly over her face. Which source is most likely to provide the input that allows for the woman's unique ability?
Correct Answer: C
Rationale: The correct answer is C, special visceral afferent cells. These cells are responsible for functions like taste and smell. In individuals with severe visual and auditory deficits, their other sensory abilities, such as touch, can be heightened. Special somatic afferent fibers (choice
A) are involved in sensations like touch and vibration from the skin and muscles, but they are not specific to the face. General somatic afferents (choice
B) transmit sensory information from the skin, muscles, and joints, but they are not specialized for the unique ability described. General visceral afferent neurons (choice
D) are responsible for transmitting sensory information from internal organs, not relevant to the woman's ability to identify individuals through touch on her face.
