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. The client was treated for vancomycin-resistant enterococcus (VRE) during a previous admission. B. The client had blood cultures drawn from the central line. C. The client's central line dressing was changed using clean technique. D. The client has received antibiotics and intravenous fluids through the same line.

Correct Answer is C

Explanation

A. The treatment for vancomycin-resistant enterococcus (VRE) in a previous admission is not directly related to the development of CLABSI in the current situation. The infection is more likely caused by improper handling or maintenance of the central line.
B. Drawing blood cultures from the central line, while not ideal, is not the most likely cause of CLABSI. Proper technique can mitigate the risk of introducing infection during this procedure.
C. Changing the central line dressing using clean technique instead of sterile technique increases the risk of introducing pathogens to the central line site, leading to a central line-associated bloodstream infection (CLABSI).
D. Receiving antibiotics and intravenous fluids through the same line does not typically cause CLABSI if the line is properly maintained and sterile techniques are observed during administration.
