Correct Answer is A

Explanation

A. Vasopressin has a vasoconstrictive effect, which means it narrows blood vessels while nitroglycerin has a vasodilatory effect, meaning it widens blood vessels. Combining these two medications could potentially lead to a significant drop in blood pressure and increase the risk of angina or myocardial infarction.
B. While hyperglycemia and insulin use are relevant for managing diabetes, they are not directly related to the use of Vasopressin. Vasopressin's main concerns are related to fluid balance and blood pressure rather than glucose levels.
C. Vasopressin can actually help to increase blood pressure, which might be beneficial for a patient with hypotension.
D. The family history of ovarian cancer does not have a direct impact on the use of Vasopressin. Vasopressin’s use is more closely related to cardiovascular and fluid balance issues rather than cancer history.

A. Hypernatremia, and subsequent seizures B. Hyponatremia, and subsequent water intoxication C. Hyperkalemia, and subsequent seizures D. Fluid volume overload, and subsequent crackles in the lungs

Correct Answer is A

Explanation

A. Hypernatremia is a condition where the sodium level in the blood is abnormally high. This occurs in DI due to excessive water loss without adequate replacement. Seizures can be a serious complication of severe hypernatremia as it disrupts the normal function of the brain.
B. Hyponatremia is low sodium levels, which is opposite to what happens in DI.
C. Hyperkalemia is high potassium levels, unrelated to DI.
D. Fluid volume overload is also opposite to what happens in DI, as patients with DI lose excessive fluids.
