Endocrine CCRN Questions With
Accurate Answers
A pt is in the PICU w DKA. Insulin gtt, latest labs reveal glucose remains elevated
so the insulin gtt is to be continued without any changes. K+=5.1 and
Chloride=118. Which of the following changes in the maintenance fluid does the
nurse anticipate?
a. Refrain from K+ admin
b. Add K+ Chloride
c. Add K+ Acetate
d. No changes as the electrolytes are in normal range correct answer C. Add K+
Acetate
- Since the K+ level will continue to decrease as the insulin is administered, it is
anticipated the child will need additional K+ added to fluids. It should be added in
the form of acetate as the chloride is currently elevated.
All of the following can lead to DI except?
a. Neurosurgery
b. Brain tumor
c. Sickle cell disease
d. Vasopressin excess correct answer d. Vasopressin excess
- In DI, there is a deficit of vasopressin not as excess. Neurosurgery and brain
tumors are examples of central DI where the hypothalamus and the pituitary are
dysfunctional. In sickle cell disease there is damage to the kidneys causing an
altered response to ADH

A pt is in the PICU w DKA. Insulin gtt, latest labs reveal glucose remains elevated so the insulin gtt is to be continued without any changes. K+=5.1 and Chloride=118. Which of the following changes in the maintenance fluid does the nurse anticipate? a. Refrain from K+ admin b. Add K+ Chloride c. Add K+ Acetate d. No changes as the electrolytes are in normal range correct answer C. Add K+ Acetate

  • Since the K+ level will continue to decrease as the insulin is administered, it is anticipated the child will need additional K+ added to fluids. It should be added in the form of acetate as the chloride is currently elevated. All of the following can lead to DI except? a. Neurosurgery b. Brain tumor c. Sickle cell disease d. Vasopressin excess correct answer d. Vasopressin excess
  • In DI, there is a deficit of vasopressin not as excess. Neurosurgery and brain tumors are examples of central DI where the hypothalamus and the pituitary are dysfunctional. In sickle cell disease there is damage to the kidneys causing an altered response to ADH

Child w DKA admitted at 1300. BG 1124 mg/dL and pH 6.9. Insulin gtt begun at 0. U/kg/hr. At 1500, labs reveal a BG of 600 mg/dL and a pH of 7.1. After notifying the provider, the nurse anticipates the following order: a. Continue w current insulin infusion and continue to monitor. b. Continue w current insulin infusion and administer normal saline bolus of 10 ml/kg. c. Hold insulin infusion and reassess labs in 1 hour. d. Continue insulin infusion and add dextrose infusion. correct answer d. continue insulin infusion and add dextrose infusion.

  • The desired decrease in glucose levels is 80-100 mg/dl/hr. If the glucose decreases at a faster rate, the risk of cerebral edema increases. Normal saline fluids boluses are administered judiciously for signs of shock but have potential to decrease the glucose level as well. Insulin infusion should not be stopped until acidosis has been corrected. Pt in DKA. The nurse suspects an error in the report when given the lab results: a. serum pH 7. b. serum osmolality 270 c. serum K 5. d. serum HCO3 6 correct answer b. serum osmolality 270
  • serum osmolality elevated in DKA due to massive osmotic diuresis. As the body is in acidotic state, pH <7.3 and HCO3 <15. Potassium elevated due to acidosis and decreased perfusion. Pt w DKA. Serum glucose 986 at noon when IV insulin started at 0.1 u/kg/hr. At 1400, his glucose was 682. Which of the following does the nurse anticipate? a. Decrease insulin infusion to 0.5 u/kg/hr and recheck glucose in 1 hour
  • ADH stored in posterior pituitary. Allows renal collecting ducts to become more permeable to water creating a more concentrated urine. In its absence, more fluid is excreted in urine. Which of the following is true concerning osmolality? a. normal blood osmolality is 200 mOsm/L b. A normal urine osmolality is 280 mOsm/L c. Urine osmolality should be slightly higher than blood d. Blood osmolality should be slightly higher than urine correct answer C. Urine osmolality should be slightly higher than blood
  • Normal blood osmolality 280 mOsm/L, normal urine osmolality 300 mOsm/L. Which of the following is true regarding the release of insulin? a. Circulating epinephrine will prevent its release. b. It prevents glucose from being converted to glycogen. c. Its release increases the use of fats as an energy source d. It causes fatty acids to be converted to triglycerides correct answer d. It causes fatty acids to be converted to triglycerides.
  • The release of insulin causes fatty acids to be converted to triglycerides and glucose to be converted to glycogen. Epinephrine does promote its release and its release causes the body to stop using fats as an energy source. Which of the following represents the way in which osmolality is calculated? a. Na + (glucose/2.8) + (BUN/18) b. Na + (glucose/18) + (BUN/2.8) c. (NaX2) + (glucose/18) + (BUN/2.8)

d. (NaX2) + (glucose/2.8) + (BUN/18) correct answer C. (NaX2) + (glucose/18) + (BUN/2.8) Which of the following would be found in a child w DI? a. Plasma osmolality 230 b. Serum sodium 152 c. Urine osmolality 325 d. Urine spec grav 1.040 correct answer B. serum sodium 152

  • In DI the osmolality and sodium are both elevated. Urine osmolality and spec gravity are decreased.
