A nasal spray of desmopressin acetate (DDAVP) is used to treat which endocrine disorder of the pituitary gland?
Diabetes insipidus
Acute adrenocortical insufficiency
Hypopituitarism
Syndrome of inappropriate antidiuretic hormone
The Correct Answer is A
Choice A reason:
Diabetes insipidus: Desmopressin acetate (DDAVP) is primarily used to treat central diabetes insipidus, a condition where the body lacks sufficient antidiuretic hormone (ADH) due to issues with the pituitary gland or hypothalamus. This hormone helps regulate water balance in the body, and desmopressin acts as a synthetic replacement to reduce frequent urination and excessive thirst.
Choice B Reason:
Acute adrenocortical insufficiency: This condition, also known as Addison’s disease, involves insufficient production of cortisol and aldosterone by the adrenal glands. Desmopressin is not used to treat this condition as it does not address the hormonal deficiencies involved.
Choice C Reason:
Hypopituitarism: This condition involves the underproduction of one or more hormones by the pituitary gland. While desmopressin can be used to manage specific symptoms related to ADH deficiency, it is not a comprehensive treatment for hypopituitarism, which requires hormone replacement therapy for multiple hormones.
Choice D Reason:
Syndrome of inappropriate antidiuretic hormone (SIADH): SIADH is characterized by excessive release of ADH, leading to water retention and hyponatremia. Desmopressin is not used to treat SIADH; in fact, it would exacerbate the condition by increasing ADH levels.

Correct Answer is A
Explanation
Choice A reason:
Wearing cotton underpants is recommended to prevent urinary tract infections (UTIs) in young girls. Cotton is a breathable fabric that allows air to circulate, reducing moisture and creating an environment less conducive to bacterial growth. This helps to keep the genital area dry and clean, which is important in preventing UTIs.
Choice B reason:
Limiting trips to the bathroom is not recommended for preventing UTIs. In fact, it is important for young girls to urinate frequently to flush out bacteria from the urinary tract. Holding urine for extended periods can increase the risk of bacterial growth and infection. Therefore, encouraging regular bathroom trips is a better practice for preventing UTIs.
Choice C reason:
Decreasing salt intake is not directly related to preventing UTIs. While a healthy diet is important for overall health, there is no specific evidence linking salt intake to the prevention of urinary tract infections. The focus should be on practices that directly reduce the risk of bacterial growth and infection in the urinary tract.
Choice D reason:
Soaking in a bathtub, especially with bubble baths or perfumed soaps, can increase the risk of UTIs. These substances can irritate the urethra and create an environment conducive to bacterial growth. It is better to avoid prolonged baths with such products and instead opt for quick showers to maintain hygiene without increasing the risk of infection.
Correct Answer is C
Explanation
Choice A reason:
Foster self-care activities: Encouraging self-care activities is important for children with hemiplegic cerebral palsy as it promotes independence and self-esteem. However, it is not the highest priority compared to ensuring the child’s safety and accessibility in their home environment.
Choice B Reason:
Improve the child’s communication skills: Enhancing communication skills is crucial for the child’s social and emotional development. Effective communication can significantly improve the child’s quality of life. However, while important, it is not the most immediate priority compared to modifying the home environment for safety.
Choice C Reason:
Modify the home environment for safety and accessibility: Ensuring the home environment is safe and accessible is the top priority. Children with hemiplegic cerebral palsy may have mobility challenges, and a safe environment can prevent injuries and promote independence. This modification directly impacts the child’s daily life and overall well-being.
Choice D Reason:
Provide respite services for the parents: Offering respite services is beneficial for the parents’ mental and emotional health, allowing them to take breaks and recharge. While this is important, it is not the primary concern compared to the child’s immediate safety and accessibility needs.
