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. A decrease in saliva production may aggravate the disorder is not correct. In fact, hyperemesis gravidarum is often associated with an increase in saliva production (ptyalism) rather than a decrease.

B. Decreasing gastric secretions lead to increased nausea is inaccurate. The issue in hyperemesis gravidarum is typically an increase in nausea and vomiting, not a direct link to decreased gastric secretions.

C. An increase in human chorionic gonadotropin (hCG) levels may contribute to this disorder is correct. Elevated hCG levels are thought to play a role in the development of hyperemesis gravidarum, as they may contribute to increased nausea and vomiting.

D. Symptoms begin and are most severe during the second trimester of pregnancy is incorrect. Hyperemesis gravidarum typically starts in the first trimester and can persist beyond that if not managed. Symptoms do not usually peak in the second trimester.

A. Supine hypotension syndrome B. Pregnancy-induced hypotension C. Anxiety D. Hypoglycemia

Correct Answer is A

Explanation

A. Supine hypotension syndrome occurs when the gravid uterus compresses the inferior vena cava when the woman is lying flat on her back, leading to decreased venous return, lowered cardiac output, and a drop in blood pressure. This can cause dizziness, lightheadedness, and sometimes fainting. It is more common in the later stages of pregnancy, such as at 38 weeks.

B. Pregnancy-induced hypotension refers to a decrease in blood pressure due to pregnancy, but it typically does not occur specifically when lying on the back, and is not the main cause of dizziness when positioned in that way.

C. Anxiety can cause dizziness, but it is not the most likely cause of dizziness related to lying flat on the back, especially in late pregnancy.

D. Hypoglycemia can cause dizziness, but it is not typically triggered by a change in position like lying on the back, making it less likely in this scenario.
