Which of the following is/are an example(s) of asexual reproduction?
- A. Fission.
- B. Fragmentation.
- C. Budding.
- D. All of the abov
Correct Answer: D
Rationale: The correct answer is D: All of the above. Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes or fertilization.
- Fission: Organism splits into two or more parts, each regenerating into a new individual.
- Fragmentation: Parent organism breaks into fragments, with each fragment developing into a new individual.
- Budding: New individuals develop as outgrowths or buds from the parent organism.
All these processes result in genetically identical offspring, making them examples of asexual reproduction.
While you are orienting a new RN to the medical-surgical unit, you observe the orientee accomplishing all of the following actions while caring for a client with severe pelvic inflammatory disease (PID), who has been admitted to the hospital for administration of IV antibiotics. Which one will require that you intervene most quickly?

- B. The new RN offers the client an ice pack to decrease her abdominal pain.
- C. The new RN positions the client flat in bed while helping her take a bath.
- D. The new RN teaches the client she should not have intercourse for 2 months.

How many autosomes does a human primary spermatocyte have?
- A. 34
- B. 44
- C. 54
- D. 33
Correct Answer: B
Rationale: The correct answer is B (44 autosomes) because a human primary spermatocyte is a diploid cell containing a total of 44 autosomes. This is because humans have 22 pairs of autosomes in their somatic cells. During meiosis I, the primary spermatocyte undergoes replication and recombination, resulting in 22 pairs of autosomes (44 autosomes) that will be divided into two haploid secondary spermatocytes. Choices A, C, and D are incorrect because they do not reflect the correct number of autosomes present in a human primary spermatocyte.
Large process on the femur that is present for attachment of muscles is
- A. condyle
- B. tubercle
- C. bone head
- D. trochanter
Correct Answer: B
Rationale: The correct answer is B: tubercle. A tubercle is a small rounded projection on a bone where muscles and ligaments can attach. In this case, the large process on the femur that serves as an attachment site for muscles is a tubercle.
Condyle (choice A) is a rounded prominence at the end of a bone, typically for articulation with another bone. Bone head (choice C) refers to the rounded end of a bone, usually forming a joint. Trochanter (choice D) is a large, blunt process on the femur that serves as an attachment point for muscles, but it is not the specific term for the large process on the femur mentioned in the question.
After arriving for your shift in the emergency department (ED), you receive change-of-shift report about all of these clients. Which one do you need to assess first?
- A. A 19-year-old client with scrotal swelling and severe pain that has not decreased with elevation of the scrotum.
- B. A 25-year-old client who has a painless indurated lesion on the glans penis.
- C. A 44-year-old client with an elevated temperature, chills, and back pain associated with recurrent prostatitis.
- D. A 77-year-old client with abdominal pain and acute bladder distention.
Correct Answer: A
Rationale: Severe scrotal pain unrelieved by elevation suggests testicular torsion, a urologic emergency.
