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."
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. The time of the burn helps in understanding how long the client has been exposed and may influence the assessment of burn progression, but it does not directly determine the severity.
B. The depth of the burn is the primary factor in assessing burn severity. It determines the level of tissue damage and guides treatment decisions. Depth classifications include superficial, partial-thickness, and full-thickness burns.
C. The cause of the burn is important for treatment considerations and understanding the mechanism of injury but does not impact the assessment of burn severity.
D. The location of the burn affects the potential for complications and functional impairment but is secondary to the depth in determining overall burn severity.
Correct Answer is A
Explanation
A. Insulin lispro is a rapid-acting insulin that should be administered 15-30 minutes before a meal to manage blood glucose levels effectively. This timing helps to match the peak action of the insulin with the rise in blood glucose levels after eating.
B. Hypoglycemia from insulin lispro typically occurs within 1-3 hours of administration, not 4 hours later. Regular monitoring during this time frame is more appropriate.
C. An increase in appetite is not a direct result of insulin lispro administration and does not indicate insulin effectiveness or safety.
D. Insulin lispro and insulin glargine should not be mixed in the same syringe as they have different action profiles and pH levels, which can affect their efficacy.
