A nurse is reviewing the medical record of an adolescent and notes a calcium level of 11.4 mEq/L. Which of the following findings should the nurse expect?
Tachycardia
Diarrhea
Positive Chvostek's sign
Muscle hypotonicity
The Correct Answer is D
A. Tachycardia: Hypercalcemia is more likely to cause bradycardia (slow heart rate) due to its depressive effects on the cardiac muscle.
B. Diarrhea: Hypercalcemia typically leads to constipation, not diarrhea.
C. Positive Chvostek's sign: This is associated with hypocalcemia, not hypercalcemia.
D. Muscle hypotonicity: Hypercalcemia can lead to muscle weakness and hypotonicity due to its effects on nerve and muscle function.

Correct Answer is A
Explanation
A. Defining a sense of self: Adolescence is characterized by the search for identity and defining a sense of self. Erikson identifies this stage as "Identity vs. Role Confusion," where individuals explore and form their own identity separate from their family and childhood roles.
B. Learning to perform tasks independently: This is more typical of early childhood (Erikson's "Autonomy vs. Shame and Doubt"). During this stage, children are learning basic independence, such as dressing and feeding themselves.
C. Learning to use creative energies: This task is more relevant to the preschool age group (Erikson's "Initiative vs. Guilt"), where children engage in imaginative play and begin exploring their own ideas and creativity.
D. Building a sense of trust: Building a sense of trust is the primary task in infancy (Erikson's "Trust vs. Mistrust"), where infants develop trust in their caregivers and the world around them.
