A client with diabetes insipidus (DI) has an average urinary output of 500 ml. of dilute urine every hour for the last 4 hours. Which laboratory test is most important for the nurse to monitor?
White blood cell count.
Capillary glucose.
Urine specific gravity.
Serum sodium.
The Correct Answer is D
Choice A rationale: White blood cell count monitors for infection or inflammation. While important for general health, it does not address the massive fluid loss and electrolyte imbalances specifically caused by diabetes insipidus.
Choice B rationale: Capillary glucose monitors for diabetes mellitus. Diabetes insipidus involves antidiuretic hormone deficiency, not insulin issues; therefore, glucose levels are not the priority in managing the massive dilute polyuria seen here.
Choice C rationale: Urine specific gravity will be consistently low in diabetes insipidus. While it confirms the diagnosis of dilute urine, it is less critical than monitoring the life-threatening systemic effects of dehydration.
Choice D rationale: Serum sodium is the most important lab to monitor. Massive loss of dilute urine leads to severe hemoconcentration and hypernatremia, which can cause cerebral edema, seizures, and permanent neurological damage.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"B"},"D":{"answers":"A,B"},"E":{"answers":"B"}}
Explanation
Course breath sounds - Respiratory Distress
Decreased level of consciousness - Cerebral Edema
Seizure activity - Cerebral Edema
Irritability - Both (Can be associated with both cerebral edema and respiratory distress)
Bradycardia - Cerebral Edema
Rationale:
Course breath sounds - Respiratory Distress
Course breath sounds could indicate the presence of secretions or fluid in the airways, which is a sign of respiratory distress. It suggests that there might be a problem with the airway or lung function.
Decreased level of consciousness - Cerebral Edema
A decreased level of consciousness can be a sign of cerebral edema, which is the swelling of the brain due to increased intracranial pressure. This can lead to changes in the child's mental status and responsiveness.
Seizure activity - Cerebral Edema
Seizure activity can be a manifestation of cerebral edema. Swelling and pressure in the brain can irritate brain tissue and lead to seizures.
Irritability - Both (Can be associated with both cerebral edema and respiratory distress) Irritability can be seen in both cerebral edema and respiratory distress. In cerebral edema, the pressure on the brain can cause discomfort and irritability. In respiratory distress, the child may be uncomfortable due to difficulty breathing.
Bradycardia - Cerebral Edema
Bradycardia (slow heart rate) can be associated with increased intracranial pressure and cerebral edema. It can be a response to the pressure on the brain.
Correct Answer is B
Explanation
A) Incorrect - While discussing the potential for asymptomatic partners is important, addressing the client's concerns and providing accurate information is more immediate.
B) Correct- Syphilis and other STIs are important public health concerns. The nurse should provide accurate information, answer questions, and correct any misconceptions the client might have. This approach supports the client's knowledge and understanding of their health condition and prevents the spread of misinformation.
C) Incorrect - While discussing contraceptives is relevant to sexual health education, it may not directly address the client's concerns about their prior infections.
D) Incorrect - Notifying local health departments is important for reporting communicable diseases, but it doesn't directly address the client's current situation and concerns.
