Identify substances that, when present in significant amounts in urine, may indicate a potential diabetic health issue. (Select all that apply)
A. Urea
Urea: Urea is a normal nitrogenous waste product excreted in urine; its presence alone is not indicative of diabetes (it reflects protein metabolism/kidney function).
B. Creatinine
Creatinine: Creatinine is a normal urinary waste product used to assess kidney function; its presence alone is not diagnostic of diabetes.
C. Glucose
Glucose: Glucosuria (significant glucose in urine) suggests hyperglycemia and impaired glucose handling (common in diabetes) -indicative of a diabetic problem if present in large amounts.
D. Ketones
Ketones: Ketonuria (significant ketones in urine) indicates fat breakdown/ketosis and is a sign of uncontrolled diabetes (e.g., diabetic ketoacidosis) -indicative of diabetic metabolic disturbance.

What is the primary function of the scrotum in the male reproductive system?
A. Regulating body temperature of the testes
Regulating body temperature of the testes: Correct -the scrotum suspends the testes and adjusts their position to keep testicular temperature slightly below core body temperature, which is necessary for optimal sperm production.
B. Storing urine
Storing urine: Incorrect -urine is stored in the urinary bladder, not in the scrotum.
C. Producing sperm
Producing sperm: Incorrect -sperm are produced in the seminiferous tubules inside the testes; the scrotum is a protective/powerful thermoregulatory sac, not the sperm-producing tissue.
D. Carrying sperm to the urethra
Carrying sperm to the urethra: Incorrect -ducts such as the vas (ductus) deferens carry sperm toward the urethra; the scrotum does not transport sperm.

A student is learning about the different breathing patterns and breadth depth. Which term describes the true breathing that a resting individual may have?
A. Dyspnea
Dyspnea: Dyspnea means difficult or labored breathing (shortness of breath), not normal resting breathing.
B. Eupnea
Eupnea: Eupnea refers to normal, unlabored breathing at rest.
C. Apnea
Apnea: Apnea means a temporary absence of breathing (no breathing), not normal respiration.
D. Hyperpnea
Hyperpnea: Hyperpnea means increased depth and/or rate of breathing (e.g., during exercise), not the normal resting pattern.

Progesterone is produced by the ovaries after ovulation. What is its main function?
A. Maintaining the uterine lining for potential pregnancy
Maintaining the uterine lining for potential pregnancy: Progesterone is produced by the corpus luteum after ovulation and prepares/maintains the endometrium for implantation and early pregnancy.
B. Promoting sperm production
Promoting sperm production: Sperm production is a male function driven by FSH and testosterone; progesterone does not promote spermatogenesis.
C. Inducing uterine contractions
Inducing uterine contractions: Progesterone actually inhibits uterine contractions to help maintain pregnancy; oxytocin and prostaglandins promote contractions.
D. Enhancing follicle development
Enhancing follicle development: Follicle development is primarily stimulated by FSH and estrogen during the follicular phase; progesterone is dominant after ovulation and does not enhance follicle development.
