A cell called the ______ is a fertilized cell with 46 chromosomes.
- A. spermatozoon
- B. polar body
- C. ovum
- D. zygote
Correct Answer: D
Rationale: The correct answer is D: zygote. A zygote is formed when a sperm cell fertilizes an egg cell, resulting in a single cell with a full set of 46 chromosomes. This process is called fertilization and marks the beginning of a new individual. The other choices (A: spermatozoon, B: polar body, C: ovum) are not correct because a spermatozoon is a mature sperm cell with 23 chromosomes, a polar body is a byproduct of meiosis in the female reproductive system and has only 23 chromosomes, and an ovum is an unfertilized egg cell also containing 23 chromosomes.

Vaginal candidacies are suspected in a young woman who complains of severe vaginal itching. Which of the following nursing actions should be performed first when assisting in the collection of a vaginal smear for microscopic examination?
- A. Inspect the external genitalia
- B. Don gloves
- C. Wash hands
- D. Label the specimen

Infertility could develop when the sperm cells display _____.
- A. a count of 120 million per ml semen
- B. increased acrosomal activity
- C. normal morphology
- D. a count of less than 20 million per ml semen
Correct Answer: D
Rationale: The correct answer is D because a low sperm count (less than 20 million per ml semen) can lead to infertility as it decreases the chances of successful fertilization. A high sperm count (choice A) is actually beneficial for fertility. Increased acrosomal activity (choice B) can enhance fertilization potential. Normal morphology (choice C) refers to the shape and size of sperm, which is important for fertility but not the primary factor in infertility due to low sperm count. Overall, a low sperm count is the most significant factor in infertility.
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.
Which assessment technique does a nurse use to assess the inguinal region and femoral area of a male patient as he is standing and straining?
- A. Palpates the femoral artery
- B. Palpates the inguinal lymph nodes
- C. Observes for a bulge through the inguinal region
- D. Observes for discoloration of the inguinal ring
Correct Answer: C
Rationale: The correct answer is C because when a nurse assesses the inguinal region and femoral area of a male patient standing and straining, they are checking for hernias. By observing for a bulge through the inguinal region, the nurse can identify any potential hernias, such as inguinal hernias. Palpating the femoral artery (choice A) is not relevant to assessing hernias. Palpating the inguinal lymph nodes (choice B) is not appropriate for assessing hernias in this scenario. Observing for discoloration of the inguinal ring (choice D) is not a typical sign of hernias. Therefore, choice C is the most appropriate assessment technique in this situation.
