When describing the events associated with the determination of sex of a fetus, which of the following would the nurse most likely include in the discussion?
- A. Genes on the Y chromosome
- B. Formation of ovaries
- C. Rising testosterone levels
- D. Neurochemical inhibition
Correct Answer: A
Rationale: Genes on the Y chromosome (A), particularly the SRY gene, initiate male sex determination by triggering testicular development. Ovary formation (B) and testosterone rise (C) are outcomes, not primary events, and neurochemical inhibition (D) is not relevant.

A woman comes to the clinic for a routine visit. While interviewing the client and obtaining a sexual history, the client states, I?ve always wondered what is happening in my body when I become sexually aroused. The nurse would incorporate an understanding of which of the following as the control mechanism?
- A. Sympathetic nervous system
- B. Endocrine system
- C. Parasympathetic nervous system
- D. Central nervous system
Correct Answer: C
Rationale: The parasympathetic nervous system (C) controls sexual arousal by promoting vasodilation and lubrication. The sympathetic system (A) is involved in orgasm, the endocrine system (B) plays a secondary role, and the central nervous system (D) is too broad.
A nurse is reviewing the medical record of a client with a sexual dysfunction. Which of the following if noted in the client?s history would the nurse identify as a possible contributing factor? Select all that apply.
- A. Antihypertensive therapy
- B. Diabetes
- C. Peptic ulcer disease
- D. Appendectomy at age 15 years
- E. Occasional alcohol use
Correct Answer: A,B,E
Rationale: Antihypertensives (A), diabetes (B), and alcohol use (E) can contribute to sexual dysfunction by affecting vascular, neurological, or hormonal function. Peptic ulcer disease (C) and a distant appendectomy (D) are unlikely contributors.
A client with premature ejaculation is prescribed sertraline as part of the treatment plan. The nurse explains the medication to the client, informing him that the effectiveness of the drug will most likely be evident in approximately which time frame?
- A. 5 to 7 days
- B. 1 to 2 weeks
- C. 3 to 4 weeks
- D. 6 to 8 weeks
Correct Answer: C
Rationale: Sertraline, an SSRI, typically takes 3 to 4 weeks (C) to achieve therapeutic effects for premature ejaculation by modulating serotonin levels. Shorter time frames (A, B) are too brief, and 6 to 8 weeks (D) is more typical for depression.
A sexual history of a female client reveals that the client has a normal sex drive and reports of orgasm through means other than intercourse. The client also has a history of being raped several years ago. The client reports spasms of the perineal and outer vaginal muscles when vaginal intercourse is attempted. The nurse interprets these findings as suggesting which of the following?
- A. Priapism
- B. Dyspareunia
- C. Sexual aversion disorder
- D. Vaginismus
Correct Answer: D
Rationale: Vaginismus (D) involves involuntary vaginal muscle spasms preventing intercourse, often linked to trauma like rape. Priapism (A) is male-specific, dyspareunia (B) is pain during intercourse, and sexual aversion disorder (C) involves avoidance of sexual activity.
A nurse is preparing a presentation for a local senior group about sexuality and sexual behaviors in older adults. Which of the following would the nurse need to address? Select all that apply.
- A. Decreased vaginal lubrication
- B. Decreased amount of sperm
- C. Enhanced clitoral response
- D. Thickening of vaginal mucosa
- E. Increased ejaculation time
Correct Answer: A,B,E
Rationale: Aging causes decreased vaginal lubrication (A), reduced sperm production (B), and increased ejaculation time (E). Clitoral response (C) typically decreases, and vaginal mucosa thins (D), not thickens, with age.
