An 86-year-old woman had an anterior and posterior colporrhaphy (A and P repair) several days ago. The client has been unwilling to ambulate or cough effectively. Her retention catheter was discontinued 8 hours ago. Which information obtained during your assessment has the most immediate implications for her care?
- A. Oral temperature is 100.7°F.
- B. Abdomen is firm and tender to palpation above the symphysis pubis.
- C. Breath sounds are decreased with fine crackles audible at both bases.
- D. Apical pulse is 86 and slightly irregular.
Correct Answer: B
Rationale: A firm, tender abdomen suggests urinary retention, requiring immediate action.

A newborn infant obtains maternal antibodies from the mother's
- A. laguno.
- B. colostrum.
- C. rubell
- D. placent
Correct Answer: B
Rationale: The correct answer is B: colostrum. Colostrum is the first milk produced by the mother after giving birth. It is rich in antibodies, providing passive immunity to the newborn. This helps protect the infant from infections until its own immune system fully develops.
A: laguno - Not a substance related to maternal antibodies.
C: rubell - Incorrect spelling and not relevant to maternal antibodies.
D: placent - While the placenta does provide nutrients and oxygen to the fetus, it is not the source of maternal antibodies transferred to the newborn.
At what point in life does a female begin her monthly ovarian cycle?
- A. At birth
- B. At puberty
- C. At middle age
- D. At menopause
Correct Answer: B
Rationale: The correct answer is B: At puberty. The monthly ovarian cycle, also known as the menstrual cycle, begins at puberty when a female's body matures and starts ovulating. This is typically around the age of 11-14. At birth (A), females already have all their eggs but do not start ovulating until puberty. Middle age (C) refers to the period around 40-65, which is not when the cycle begins. Menopause (D) is the cessation of the menstrual cycle, marking the end of reproductive years, typically around the age of 45-55.
With respect to ejaculation which of the following statements is incorrect.
- A. ejaculation is the result of para-sympathetic stimulation
- B. ejaculation results from the summation of synaptic potentials
- C. during ejaculation semen is expelled by rapid contraction of the urethral smooth muscle
- D. ejaculation results is the discharge of sperm, seminal vesicle and prostatic secretions
Correct Answer: A
Rationale: The correct answer is A because ejaculation is primarily controlled by the sympathetic nervous system, not the para-sympathetic system. The sympathetic nervous system triggers the contraction of smooth muscles to allow for ejaculation. Choice B is incorrect because ejaculation is not a result of summation of synaptic potentials, but rather a coordinated response. Choice C is incorrect because semen is expelled by rhythmic contractions of the pelvic floor muscles, not the urethral smooth muscle. Choice D is incorrect because ejaculation involves the discharge of sperm, seminal vesicle, prostatic secretions, and other fluids from the reproductive system.
A scientist studying developmental physiology performs an experiment in which a substance is given to pregnant rats that give birth to pups that have XY chromosomes but female genital organs. What was the substance given to the rats?
- A. An antibody that blocked the effect of human chorionic gonadotropin in the embryo and fetus
- B. A large quantity of estrogen-like compounds
- C. Follicle-stimulating hormone
- D. Testosterone
Correct Answer: A
Rationale: The correct answer is A: An antibody that blocked the effect of human chorionic gonadotropin in the embryo and fetus. Human chorionic gonadotropin (hCG) is crucial for male sexual differentiation. Blocking its effects would lead to the development of female genital organs in pups with XY chromosomes. Estrogen-like compounds (B) and follicle-stimulating hormone (C) are not directly involved in male sexual differentiation. Testosterone (D) is responsible for male sexual development, so giving testosterone would not result in female genital organs in XY pups.
The ovary:
- A. is a gland with mixed role;
- B. has exocrine role, secreting the female sexual hormones;
- C. has endocrine role, generating the ovules;
- D. represents the female gonad;
Correct Answer: D
Rationale: The correct answer is D because the ovary is indeed the female gonad responsible for producing eggs and releasing female sex hormones like estrogen and progesterone. This is its primary function, making it the most accurate choice. Choice A is incorrect as the ovary's main role is reproductive rather than mixed. Choice B is incorrect as the ovary secretes both female sex hormones and eggs, not just hormones. Choice C is incorrect as ovules are part of the female reproductive system but not the main function of the ovary.
