Which of the following is a potential cause of male infertility?
- A. Varicocele
- B. Cryptorchidism
- C. Testicular cancer
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D - All of the above. Varicocele, Cryptorchidism, and Testicular cancer are all potential causes of male infertility. Varicocele is an abnormal enlargement of the veins within the scrotum, which can lead to reduced sperm quality. Cryptorchidism is a condition where one or both testicles fail to descend into the scrotum, affecting sperm production. Testicular cancer can also impact fertility by affecting the function of the testes. Therefore, all three conditions can contribute to male infertility. Choices A, B, and C are incorrect because each of them individually can cause male infertility, making D the most comprehensive and correct answer.

A nurse is assessing a client who is postpartum and has idiopathic thrombocytopenia purpura (ITP). Which of the following findings should the nurse expect?
- A. Decreased platelet count.
- B. Increased erythrocyte sedimentation rate (ESR).
- C. Decreased megakaryocytes.
- D. Increased WBC.
Correct Answer: A
Rationale: Idiopathic thrombocytopenia purpura (ITP) is characterized by a decreased platelet count, which can lead to an increased risk of bleeding.
Which hormone is responsible for stimulating the growth and development of the ovarian follicles?
- A. Estrogen
- B. Progesterone
- C. Follicle-stimulating hormone (FSH)
- D. Luteinizing hormone (LH)
Correct Answer: C
Rationale: The correct answer is C: Follicle-stimulating hormone (FSH). FSH stimulates the growth and development of ovarian follicles by promoting the production of estrogen in the ovaries. It helps in the maturation of the follicles and ultimately leads to ovulation. Estrogen (A) and Progesterone (B) are hormones produced by the ovaries but do not directly stimulate the growth of ovarian follicles. Luteinizing hormone (LH) (D) is responsible for triggering ovulation and the formation of the corpus luteum, not for the growth and development of ovarian follicles.
A nurse is caring for a newborn who is experiencing neonatal abstinence syndrome. Which of the following actions should the nurse take?
- A. Decrease the lighting levels in the nursery.
- B. Wrap the newborn loosely in a blanket.
- C. Provide frequent stimulation for the newborn.
- D. Encourage frequent eye contact with the newborn during feedings
Correct Answer: A
Rationale: Decreasing lighting levels helps reduce overstimulation, which can exacerbate symptoms of neonatal abstinence syndrome.
A nurse is preparing to assess fetal heart tones for a client who is at 12 weeks of gestation. Which of the following actions should the nurse take?
- A. Place the client in a side-lying position prior to assessing the fetal heart rate
- B. Measure the fundal height to determine the placement of the ultrasound stethoscope.
- C. Position the ultrasound stethoscope above the symphysis pubis to assess the fetal heart rate.
- D. Perform Leopold maneuvers prior to auscultating the fetal heart rate.
Correct Answer: C
Rationale: At 12 weeks of gestation, the fetal heart rate is best assessed using an ultrasound stethoscope positioned above the symphysis pubis. Leopold maneuvers are not necessary at this early stage.
A nurse is assessing a late preterm newborn. Which of the following manifestations is an indication of hypoglycemia?
- A. Hypertonia
- B. Increased feeding
- C. Hyperthermia
- D. Respiratory distress
Correct Answer: D
Rationale: Respiratory distress in a late preterm newborn can be a sign of hypoglycemia, as low blood sugar levels can impair respiratory function.
