Which situation would be part of the normal reproductive cycle of a human?
- A. the presence of testosterone regulating gamete production in a male
- B. estrogen in concentrations that would produce sperm in a female
- C. a high progesterone level in a male
- D. a low insulin level in either a male or a female
Correct Answer: A
Rationale: Step 1: Testosterone is a hormone primarily produced by the testes in males, regulating sperm production.
Step 2: Gametes are reproductive cells (sperm in males), crucial for the reproductive cycle.
Step 3: Therefore, the presence of testosterone regulating gamete production in a male is a normal part of the reproductive cycle.
Summary:
- Option B is incorrect as estrogen, a female sex hormone, does not produce sperm.
- Option C is incorrect as progesterone is a hormone mainly involved in the menstrual cycle and pregnancy, not in males.
- Option D is incorrect as insulin is a hormone related to glucose metabolism, not directly involved in the reproductive cycle.

About the Fallopian tubes we can state the following:
- A. are funnel-shaped, with edges flared towards the uterus;
- B. the medial extremity displays flares;
- C. it is linked to the uterus through the uterine ostium;
- D. the lateral extremity opens in the abdominal cavity;
Correct Answer: A
Rationale: The correct answer is A because Fallopian tubes are indeed funnel-shaped, with edges flared towards the uterus. This shape helps capture the released egg from the ovary and guide it towards the uterus for potential fertilization. The other choices are incorrect because the medial extremity does not display flares (B), the Fallopian tube is not directly linked to the uterus through the uterine ostium (C), and the lateral extremity does not open in the abdominal cavity (D). Therefore, choice A is the most accurate description of the Fallopian tubes based on their anatomy and function.
Anterior to the vagina and urethral openings is the
- A. Labia majora
- B. Labia minor
- C. Mons pubis
- D. Cervical sphincter
Correct Answer: A
Rationale: The correct answer is A: Labia majora. The labia majora are located anterior to the vagina and urethral openings, providing protection and support. The labia minora are internal to the labia majora. The mons pubis is the rounded mass of fatty tissue located over the pubic symphysis. Cervical sphincter is not a relevant anatomical structure in this context. Therefore, the labia majora is the correct choice based on its anatomical location and function.
Which is a sign of benign prostatic hyperplasia?
- A. Weight loss
- B. Bone pain
- C. Fever
- D. Nocturia
Correct Answer: D
Rationale: The correct answer is D: Nocturia. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, leading to urinary symptoms like frequent urination, especially at night (nocturia). Weight loss, bone pain, and fever are not typical signs of BPH. Nocturia is a common symptom due to the prostate gland pressing against the urethra, causing urinary retention. It is important to differentiate BPH symptoms from other potential causes to provide appropriate treatment.
After a 26-yr-old patient has been treated for pelvic inflammatory disease, the nurse will plan to teach about the
- A. use of hormone therapy (HT).
- B. potential complication of infertility.
- C. irregularities in the menstrual cycle
- D. changes in secondary sex characteristics.
Correct Answer: B
Rationale: The correct answer is B - potential complication of infertility. Pelvic inflammatory disease (PID) can lead to scarring and damage to the reproductive organs, increasing the risk of infertility. Teaching about this potential complication is crucial for the patient's understanding of the long-term consequences of PID. Option A (use of hormone therapy) is not directly related to PID treatment. Option C (irregularities in the menstrual cycle) may occur but is not the primary concern post-PID treatment. Option D (changes in secondary sex characteristics) is not a common complication of PID. Therefore, option B is the most appropriate choice for teaching post-PID treatment.
During pregnancy, the uterine smooth muscle is quiescent. During the 9th month of gestation the uterine muscle becomes progressively more excitable. What factors contribute to the increase in excitability?
- A. Placental estrogen synthesis rises to high rates
- B. Progesterone synthesis by the placenta decreases
- C. Uterine blood flow reaches its highest rate
- D. Prostaglandin E2 synthesis by the placenta decreases
Correct Answer: B
Rationale: The correct answer is B: Progesterone synthesis by the placenta decreases. Progesterone maintains uterine quiescence during pregnancy by inhibiting uterine contractions. As progesterone levels decline towards the end of pregnancy, the uterine muscle becomes more excitable. Placental estrogen synthesis (Choice A) does not directly affect uterine excitability. Uterine blood flow (Choice C) is not a direct factor in uterine muscle excitability. Prostaglandin E2 (Choice D) actually increases towards the end of pregnancy, contributing to uterine contractions rather than decreasing excitability.
