The nurse will plan to teach a 51-yr-old man who is scheduled for an annual physical examination about a(n)
- A. increased risk for testicular cancer.
- B. possible changes in erectile function.
- C. normal decreases in testosterone level.
- D. prostate specific antigen (PSA) testing.
Correct Answer: C
Rationale: The correct answer is C: normal decreases in testosterone level. At the age of 51, it is important to educate the man about the normal age-related decline in testosterone levels, which can affect various aspects of health. This information will help manage expectations and address potential symptoms. Option A is incorrect as testicular cancer risk typically decreases with age. Option B may be a concern but is not the primary focus of education for a routine physical exam. Option D (PSA testing) is more relevant for prostate health, which is not the main focus of education for a 51-year-old man's annual physical exam.
Which cell has been fertilized by a sperm cell?
- A. primary oocyte
- B. secondary oocyte
- C. ovum
- D. oogonia
Correct Answer: C
Rationale: The correct answer is C (ovum) because the ovum is the mature and fertilized egg cell resulting from the fusion of a sperm cell and an egg cell during fertilization. The primary oocyte (A) is an immature egg cell that has not undergone fertilization. The secondary oocyte (B) is the egg cell released during ovulation but has not yet been fertilized. Oogonia (D) are the precursor cells that give rise to primary oocytes through the process of oogenesis. Therefore, the ovum is the only choice that accurately represents a fertilized egg cell.
Your 30 year old female patient is c/o bad-smelling vaginal discharge with mild itching for about 3 weeks. Douching did not help. Denies painful urination or intercourse. She noticed the smell increased after intercourse and during her period last week. There are no lesions on the perineum. No lymphadenopathy. On speculum examination, there is a thin gray-white discharge. The pH of the discharge is over 4.5 and there is a fishy odor when potassium hydroxide (KOH) is applied to the vaginal secretions on the slide. Wet prep shows epithelial cells with stippled border (clue cells). What type of vaginitis best describes the findings?
- A. Trichomonas vaginitis
- B. Candida vaginitis
- C. Bacterial vaginosis
- D. Atrophic vaginitis
Correct Answer: C
Rationale: The correct answer is C: Bacterial vaginosis. The key findings in this scenario point towards bacterial vaginosis. The presence of thin gray-white discharge, fishy odor with KOH, pH over 4.5, and clue cells on wet prep are classic for bacterial vaginosis. Trichomonas vaginitis (choice A) typically presents with yellow-green frothy discharge and motile trichomonads on microscopy. Candida vaginitis (choice B) is characterized by thick, white, cottage cheese-like discharge and budding yeast or pseudohyphae on microscopy. Atrophic vaginitis (choice D) usually occurs in menopausal women due to estrogen deficiency and presents with thin, pale vaginal walls and vaginal dryness. In this case, the absence of these findings makes bacterial vaginosis the most likely diagnosis.
How many fused parts form sacrum?
- A. 4
- B. 5
- C. 6
- D. 3
Correct Answer: A
Rationale: The sacrum is formed by the fusion of 5 originally separate sacral vertebrae. However, the coccyx is the result of the fusion of 4 originally separate coccygeal vertebrae. Therefore, the sacrum itself is formed by the fusion of 4 parts, making choice A correct. Choices B, C, and D are incorrect as they do not accurately reflect the anatomical structure of the sacrum.
