T or F:

when administering a drug via a parenteral route, the drug would be absorbed fasted if given per the (IM) route?

Q

perceived constipation

daily laxative, use by the patient might suggest that she perceives she is constipated, and the nurse would gather further assessment data related to the client’s bowel pattern. There is not enough data to infer actual constipation

there is 24-hur urine collection in process for a client.
the nursing assistive personnel (NAP) inadvertently empties one specimen into the toilet instead of the collection “hat”.
the nurse should:

Q

on assessment of a patient with acute renal failure, the nurse finds the following:
- distended neck veins, cool and pale skin, and crackles in the lungs.

  • hypovolemia
  • hypervolemia
  • hypercalcemia
A

hypervolemia

this patient is showing signs of fluid overload.
other findings include elevated blood pressure, bounding pulse, and increased respirations due to increased intravascular volume.

Q

what are the causes and symptoms of hypervolemia?

A
  • excessive retention of sodium and water in the ECF
  • fluid volume excess can result from excessive salt intake, disease affecting kidney or liver function, or poor pumping action of the heart
  • the retained sodium increases osmotic pressure and pulls fluid from the cells into the ECF
  • BP is elevated, pulse is bound, and respirations are increased and shallow, distended neck veins, edema, skin is pale and cool.
  • urine output becomes dilute, and volume increases.
  • rapid weight gain.
  • in severe fluid overload, the patient develops moist crackles in the lungs, dyspnea, and ascites (excess peritoneal fluid)
  • orthopnea - difficulty breathing while laying flat Hemodilution causes BUN, hematocrit, and the specific gravity of the urine to decrease.
