A nurse is teaching a student nurse about the effects of vasopressin that is prescribed for a client with diabetes insipidus. Which statement by the student nurse indicates an understanding of the teaching?

"This medication will increase the client's heart rate."

"This medication will decrease the client's blood pressure."

"This medication will decrease the client's urine specific gravity."

"This medication will decrease the client's urine output."

Answer and Explanation

The Correct Answer is D

A. Vasopressin does not typically increase the client's heart rate; its primary effect is on the kidneys and urine output.
B. Vasopressin generally increases blood pressure by promoting vasoconstriction, not decreases it.
C. Vasopressin will increase, not decrease, urine specific gravity by reducing urine output and concentrating the urine.
D. Vasopressin acts to decrease urine output by increasing water reabsorption in the kidneys, which helps manage diabetes insipidus.

Correct Answer is B

Explanation

A. Decreased prothrombin time is not typically associated with the emergent phase of a burn injury. Prothrombin time changes are more related to liver function or coagulation disorders.
B. Increased hematocrit is common in the emergent/resuscitative phase of burn injury due to fluid shifts and loss of plasma volume, leading to hemoconcentration.
C. Increased sodium is not typically seen in the emergent phase; instead, hyponatremia may occur due to fluid shifts and loss of sodium in the burn exudate.
D. Potassium deficit is more likely to occur later in the burn management phases. In the emergent phase, hyperkalemia is more common due to cell destruction and release of intracellular potassium.

A. Thiamine B. Vitamin C C. Vitamin K D. Folic acid

Correct Answer is C

Explanation

A. Thiamine deficiency is often associated with neurological symptoms, such as Wernicke-Korsakoff syndrome, rather than spontaneous bleeding or bruising. Thiamine does not directly impact the coagulation process.
B. Vitamin C deficiency can lead to scurvy, which includes symptoms such as bleeding gums and poor wound healing. However, it is not typically associated with the spontaneous bleeding and bruising seen in chronic liver failure.
C. Vitamin K is essential for the synthesis of clotting factors produced by the liver. In chronic liver failure, the liver's ability to produce these factors is impaired, leading to an increased risk of bleeding and bruising due to vitamin K deficiency.
D. Folic acid deficiency is more commonly linked to anemia and certain neurological issues, but it does not cause spontaneous bleeding or bruising. It does not directly affect coagulation factors as vitamin K does.
