A 14-year-old boy is at the pediatric clinic for a checkup. What physical changes of puberty will the nurse indicate are related to the production of testosterone?

Decrease in production of sebaceous gland secretions

Increase in muscle mass and strength

Stimulation of production of white cells and platelets

Promotion of growth of small bones

Answer and Explanation

The Correct Answer is B

A. Decrease in production of sebaceous gland secretions is incorrect. Testosterone actually increases sebaceous gland activity, leading to an increase in oil production, which can contribute to acne during puberty.

B. Increase in muscle mass and strength is correct. Testosterone plays a key role in the development of secondary male characteristics, including increased muscle mass, strength, and the growth of larger bones.

C. Stimulation of production of white cells and platelets is incorrect. While testosterone affects many bodily functions, it does not directly stimulate the production of white cells or platelets.

D. Promotion of growth of small bones is incorrect. Testosterone is more closely associated with the growth and development of larger bones (e.g., long bones), leading to height increases during puberty. It does not promote the growth of small bones.

Correct Answer is C

Explanation

A. The middle area of the fallopian tube is not the typical site for fertilization. The fertilization process most often occurs in the outer third of the fallopian tube, closer to the ovary.

B. The lower segment of the uterus is where implantation occurs after fertilization, but fertilization itself happens earlier in the fallopian tube.

C. The outer third of the fallopian tube near the ovary is the most common site of fertilization, where the sperm meets the egg shortly after ovulation.

D. The upper portion of the uterus is where the embryo implants after fertilization, but fertilization itself takes place in the fallopian tube, not in the uterus.

A. Craniofacial abnormalities B. Low birth weight C. Hypersensitivity to noise D. Hyperactivity

Correct Answer is B

Explanation

A. Craniofacial abnormalities is incorrect. While smoking during pregnancy can lead to a variety of issues, craniofacial abnormalities are not a common direct result.

B. Low birth weight is correct. Smoking during pregnancy significantly increases the risk for low birth weight, as it can restrict fetal growth by affecting placental function and blood flow to the fetus.

C. Hypersensitivity to noise is not a typical outcome associated with smoking during pregnancy. This is more related to neurological or sensory processing issues, which may have other causes.

D. Hyperactivity is incorrect. While smoking during pregnancy is associated with long-term developmental issues such as learning difficulties and behavioral problems, hyperactivity is not the immediate concern. It is more likely to be a long-term effect on cognitive and behavioral development.
