What is the primary purpose of a semen analysis in an infertility evaluation?
- A. To assess sperm count, motility, and morphology.
- B. To determine the presence of infections in the reproductive tract.
- C. To measure hormone levels affecting sperm production.
- D. To identify potential genetic anomalies in sperm.
Correct Answer: A
Rationale: The primary purpose of a semen analysis in an infertility evaluation is to assess sperm count, motility, and morphology. This is crucial as these factors directly impact male fertility. Sperm count indicates the quantity of sperm present, motility relates to their ability to move effectively towards the egg, and morphology assesses the shape and structure of sperm, which can affect their ability to fertilize an egg. Evaluating these parameters helps identify potential issues causing infertility. Other choices are incorrect as semen analysis primarily focuses on assessing sperm quality, not infections, hormone levels, or genetic anomalies in sperm.

A 44-year-old woman presents with an unexpected pregnancy. She asks the nurse, 'Is my baby going to have a birth defect? My third cousin has Down syndrome.' What is the nurse's best response?
- A. Tell the patient she is at risk for gene mutation because a birth defect in a distant relative places the woman at increased risk.
- B. Discuss the potential risk for intrauterine growth retardation due to the mother's advanced age.
- C. Discuss the patient's situation with the physician to ask for a referral to high-risk obstetrics.
- D. Discuss the potential risk for a chromosomal abnormality based on the patient's advanced age.
Correct Answer: D
Rationale: Step 1: The correct answer is D because advanced maternal age (AMA), generally defined as 35 years or older, is a well-known risk factor for chromosomal abnormalities, such as Down syndrome.
Step 2: Down syndrome is more common in babies born to mothers over the age of 35 due to the increased likelihood of errors in cell division during egg development.
Step 3: Given the patient's age of 44, she falls into the category of AMA and is at an increased risk for chromosomal abnormalities in her baby.
Step 4: Option A is incorrect as the risk is not solely based on gene mutation but rather on the increased chance of chromosomal abnormalities due to age.
Step 5: Option B is incorrect as it focuses on intrauterine growth retardation, which is not directly related to the patient's query about birth defects.
Step 6: Option C is incorrect as a referral to high-risk obstetrics may not be necessary solely based on the patient's
Lori, who is 32 years old, is taking clomiphene citrate to induce ovulation and presents to the office for a vaginal ultrasound. As the nurse is walking Lori to ultrasound, Lori mentions that over the past 12 hours she has experienced abdominal bloating, nausea, and weight gain of 5 pounds. The nurse recognizes these signs and symptoms to be associated with what condition?
- A. Ovulation
- B. Premenstrual syndrome
- C. Ovarian hyperstimulation syndrome
- D. Failed ovulation induction
Correct Answer: C
Rationale: The correct answer is C: Ovarian hyperstimulation syndrome (OHSS). OHSS is a potential complication of ovulation induction with medications like clomiphene citrate. The symptoms Lori is experiencing (abdominal bloating, nausea, and weight gain) are classic signs of moderate OHSS. The mechanism involves excessive response to the ovulation induction medication leading to enlarged ovaries and fluid accumulation in the abdomen. It is crucial to monitor patients on ovulation induction therapy for signs of OHSS to prevent severe complications.
Choice A: Ovulation - This is incorrect because the symptoms described are not typical of ovulation itself.
Choice B: Premenstrual syndrome - This is incorrect because the symptoms are not specific to premenstrual syndrome and are more indicative of a complication related to medication.
Choice D: Failed ovulation induction - This is incorrect because the symptoms suggest a response to the medication rather than a failure of ovulation.
What is the function of the highlighted region on the drawing below?
- A. It produces a fluid that nourishes the sperm.
- B. It secretes a fluid that neutralizes the acidic environment of the vagina.
- C. It is the reservoir where sperm mature.
- D. It contracts during ejaculation
Correct Answer: D
Rationale: The highlighted region likely refers to the bulbospongiosus muscle or related structures that contract during ejaculation to expel semen.
Assessment of a woman in labor reveals cervical dilation of 3 cm, cervical effacement of 30%, and contractions occurring every 7 to 8 minutes, lasting about 40 seconds. The nurse determines that this client is in:
- A. latent phase of the first stage.
- B. active phase of the first stage.
- C. pelvic phase of the second stage.
- D. early phase of the third stage.
Correct Answer: A
Rationale: The client's cervical dilation, effacement, and contraction pattern indicate that she is in the latent phase of the first stage of labor. This phase is characterized by cervical dilation of 0 to 3 cm, effacement of 0% to 40%, and contractions every 5 to 10 minutes lasting 30 to 40 seconds. The active phase of the first stage occurs with cervical dilation of 4 to 7 cm, effacement of 40% to 80%, and contractions every 2 to 5 minutes lasting 45 to 60 seconds. The perineal phase of the second stage and early phase of the third stage have different characteristics, making them incorrect choices.
What is the purpose of progesterone in supporting early pregnancy?
- A. To increase fetal growth rates.
- B. To maintain the uterine lining and prevent menstrual shedding.
- C. To stimulate ovulation during the menstrual cycle.
- D. To regulate the release of other reproductive hormones.
Correct Answer: B
Rationale: The correct answer is B because progesterone plays a crucial role in maintaining the uterine lining to support implantation and prevent menstrual shedding. Progesterone prepares the uterus for the potential implantation of a fertilized egg by thickening the endometrium. If fertilization occurs, progesterone continues to support the pregnancy by ensuring the uterine lining remains intact to provide a nurturing environment for the developing embryo. Choices A, C, and D are incorrect because progesterone's main function in early pregnancy is not to increase fetal growth rates, stimulate ovulation, or regulate the release of other reproductive hormones.
