Answer to Question 1

A
Feedback
A The first sign of pubertal changes in boys is testicular enlargement in response to
testosterone secretion, which usually occurs in Tanner stage 2 . Slight pubic hair
is present and the smooth skin texture of the scrotum is somewhat altered.
B During Tanner stages 4 and 5, facial hair appears at the corners of the upper lip
and chin.
C As testosterone secretion increases, the penis, testes, and scrotum enlarge.
D During Tanner stages 4 and 5, rising levels of testosterone cause the voice to
deepen.

Answer to Question 2

Rationale:
1. Early signs of digoxin toxicity are nausea and vomiting. Digoxin toxicity does not cause lowered blood pressure.
2. Early signs of digoxin toxicity are nausea and vomiting. Digoxin toxicity does not cause tinnitus (ringing in the ears).
3. Early signs of digoxin toxicity are nausea and vomiting. Digoxin toxicity does not cause ataxia (unsteady gait).
4. Early signs of digoxin toxicity are nausea and vomiting.
