- B. Type 2 diabetes
- C. Gestational diabetes
- D. Maturity-onset diabetes of the young (MODY)

Peripheral precocious puberty (PPP) differs from central precocious puberty (CPP) in which manner?
- A. PPP results from a central nervous system (CNS) insult.
- B. PPP occurs more frequently in girls.
- C. PPP may be viewed as a variation in sexual development.
- D. PPP results from hormonal stimulation of the hypothalamic gonadotropin-releasing hormone (Gn-RH).
Correct Answer: C
Rationale: PPP, caused by non-hypothalamic hormone sources, may be considered a variation in sexual development. CPP stems from CNS-driven Gn-RH stimulation, is more common in girls, and isn?t a variation but a pathological early puberty.
A child with hypoparathyroidism is receiving vitamin D therapy. The parents should be advised to watch for which signs or symptoms of vitamin D toxicity?
- A. Headache and seizures
- B. Weakness and lassitude
- C. Anorexia and insomnia
- D. Physical restlessness, voracious appetite without weight gain
Correct Answer: B
Rationale: Vitamin D toxicity can cause weakness, lassitude, nausea, vomiting, and renal issues like polyuria. Headaches occur but seizures do not, anorexia and insomnia are not typical, and restlessness with appetite changes suggests hyperthyroidism, not toxicity.
What clinical manifestation is considered a cardinal sign of diabetes mellitus?
- A. Nausea
- B. Seizures
- C. Impaired vision
- D. Frequent urination
Correct Answer: D
Rationale: Frequent urination (polyuria), along with glycosuria and polydipsia, is a hallmark of diabetes mellitus due to glucose-driven osmotic diuresis. Nausea and seizures are not typical, and impaired vision is a long-term complication, not a cardinal sign.
A child with hypopituitarism is being started on growth hormone (GH) therapy. Nursing considerations should be based on which knowledge?
- A. Therapy is most successful if it is started during adolescence.
- B. Replacement therapy requires daily subcutaneous injections.
- C. Hormonal supplementation will be required throughout childs lifetime.
- D. Treatment is considered successful if children attain full stature by adolescence.
Correct Answer: B
Rationale: GH therapy involves daily subcutaneous injections, with education for self-management in school-age children. It?s most effective in younger or severely deficient children, not adolescents, and isn?t needed lifelong after final height. Success involves near-final height, not necessarily by adolescence.
