When the nurse is evaluating lab data for a client 1824 hours after a major thermal burn, the expected physiological changes would include which of the following?

  • A. Elevated serum sodium
  • B. Elevated serum calcium
  • C. Elevated serum protein
  • D. Elevated hematocrit

Answer : D

(A) Sodium enters the edema fluid in the burned area, lowering the sodium content of the vascular fluid. Hyponatremia may continue for days to several weeks because of sodium loss to edema, sodium shifting into the cells, and later, diuresis. (B) Hypocalcemia occurs because of calcium loss to edema fluid at the burned site (third space fluid). (C) Protein loss occurs at the burn site owing to increased capillary permeability. Serum protein levels remain low until healing occurs. (D) Hematocrit level is elevated owing to hemoconcentration from hypovolemia. Anemia is present in the postburn stage owing to blood loss and hemolysis, but it cannot be assessed until the client is adequately hydrated.

  • A. Prevention of seizures
  • B. Prevention of uterine contractions
  • C. Sedation
  • D. Fetal lung protection

Answer : A

(A) MgSO4 is classified as an anticonvulsant drug. In preeclampsia management, MgSO4 is used for prevention of seizures. (B) MgSO4 has been used to inhibit hyperactive labor, but results are questionable. (C) Negative side effects such as respiratory depression should not be confused with generalized sedation.

The nurse would need to monitor the serum glucose levels of a client receiving which of the following medications, owing to its effects on glycogenolysis and insulin release?

  • A. Norepinephrine (Levophed)
  • B. Dobutamine (Dobutrex)
  • C. Propranolol (Inderal)
  • D. Epinephrine (Adrenalin)

Which of the following findings would be abnormal in a postpartal woman?

  • A. Chills shortly after delivery
  • B. Pulse rate of 60 bpm in morning on first postdelivery day
  • C. Urinary output of 3000 mL on the second day after delivery
  • D. An oral temperature of 101F (38.3C) on the third day after delivery

(A) Frequently the mother experiences a shaking chill immediately after delivery, which is related to a nervous response or to vasomotor changes. If not followed by a fever, it is clinically innocuous. (B) The pulse rate during the immediate postpartal period may be low but presents no cause for alarm. The body attempts to adapt to the decreased pressures intra-abdominally as well as from the reduction of blood flow to the vascular bed. (C)
Urinary output increases during the early postpartal period (1224 hours) owing to diuresis.
The kidneys must eliminate an estimated 20003000 mL of extracellular fluid associated with a normal pregnancy. (D) A temperature of 100.4F (38C) may occur after delivery as a result of exertion and dehydration of labor. However, any temperature greater than 100.4F needs further investigation to identify any infectious process.

The physician has ordered that a daily exercise program be instituted by a client with type I diabetes following his discharge from the hospital. Discharge instructions about exercise should include which of the following?

  • A. Exercise should be performed 30 minutes before meals.
  • B. A snack may be needed before and/or during exercise.
  • C. Hyperglycemia may occur 2–4 hours after exercise.
  • D. The blood glucose level should be 100 mg or below before exercise is begun.

Answer : B

(A) Exercise should not be performed before meals because the blood sugar is usually lower just prior to eating; therefore, there is an increased risk for hypoglycemia. (B)
Exercise lowers blood sugar levels; therefore, a snack may be needed to maintain the appropriate glucose level. (C) Exercise lowers blood sugar levels. (D) Exercise lowers blood sugar levels. If the blood glucose level is 100 mg or below at the start of exercise, the potential for hypoglycemia is greater.
