Concerning Muller’s cells, all are true except:
- A. They share in the formation of the limiting membranes.
- B. They are nerve cells.
- C. They have long processes.
- D. Their nuclei are present in the inner nuclear layer.
Correct Answer: B
Rationale: B: They are nerve cells.
Rationale: Muller's cells are a type of glial cell in the retina, not nerve cells. They provide structural support and play a role in maintaining the retinal environment. Other choices are true: A) They form limiting membranes, C) They have long processes, and D) Their nuclei are in the inner nuclear layer.

The condition of a hidden testicle is of which type of tissue?
- A. skeletal muscle
- B. phimosis.
- C. epithelial tissue
- D. orchiditis.
Correct Answer: D
Rationale: The correct answer is D: orchiditis. Orchiditis refers to inflammation of the testicle, which is a type of tissue found in the male reproductive system. This condition specifically affects the testicular tissue, leading to pain, swelling, and possible complications. Skeletal muscle (choice A) is not related to the testicle, phimosis (choice B) is a condition of the foreskin, and epithelial tissue (choice C) primarily covers the surface of organs, not the testicle itself. Therefore, orchiditis is the most relevant choice for a condition affecting testicular tissue.
A 50-year-old patient asks the nurse about her risk of developing a cancer of the reproductive system. What is the appropriate response by the nurse?
- A. Human papilloma virus infection and cigarette smoking are major risk factors for cervical cancer.
- B. Some of the risk factors for endometrial cancer include being age 40 or older and having a history of infertility.
- C. Ovarian cancer is not often seen in women under age 50 or those who have a family history of breast cancer.
- D. Women who have had menstrual irregularities for many years are at lower risk of developing any of the reproductive system cancers.
Correct Answer: A
Rationale: Step 1: Human papilloma virus (HPV) infection and cigarette smoking are major risk factors for cervical cancer.
Step 2: The patient is 50 years old, which puts her at risk for cervical cancer.
Step 3: HPV infection and smoking increase the risk of cervical cancer.
Step 4: Therefore, the appropriate response by the nurse is A.
Summary:
B: Endometrial cancer risk factors include obesity, not age 40, and infertility is not a primary risk factor.
C: Ovarian cancer can occur in women under 50 and family history of breast cancer is not a definitive protective factor.
D: Menstrual irregularities do not necessarily lower the risk of reproductive system cancers.
While performing a breast examination on a 22-year-old client, you obtain all of these data. Which information is of most concern?
- A. Both breasts have many nodules in the upper, outer quadrants.
- B. Client complains of bilateral breast tenderness with palpation.
- C. The breast on the right side is slightly larger than the left breast.
- D. An irregularly shaped, nontender lump is palpable in the left breast.
Correct Answer: D
Rationale: An irregularly shaped, nontender lump may indicate malignancy, requiring further investigation.
The general meaning of the term "corpus" is best described by which of the following?
- A. Abdomen
- B. Body
- C. Death
- D. Head
Correct Answer: B
Rationale: The correct answer is B: Body. Corpus commonly refers to a collection of written or spoken texts, which together form a body of work. "Body" is the best choice as it encompasses the idea of a collection or group of related items. A is incorrect as it refers specifically to the abdomen, not the general term. C, Death, and D, Head, are unrelated to the general meaning of "corpus" as they do not convey the idea of a body or collection.
Benign tumors originating in the myometrium are
- A. Fibroids
- B. Rhabdomyoma
- C. Leiomyoma
- D. Both a & c
Correct Answer: D
Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
