MedSurg2 - Final Review
A nurse is caring for a client who is prescribed a computed tomography (CT) scan with iodine-based contrast. Which actions should the nurse take to prepare the client for this procedure? (Select all that apply.) a. Ensure that an informed consent is present. b. Ask the client about any allergies. c. Evaluate the client's renal function. d. Auscultate bilateral breath sounds. e. Assess hematocrit and hemoglobin levels.
ANS: A, B, C A client who is scheduled to receive iodine-based contrast should be asked about allergies, especially allergies to iodine or shellfish. The client's kidney function should also be evaluated to determine if it is safe to administer contrast during the procedure. Finally, the nurse should ensure that an informed consent is present because all clients receiving iodine-based contrast must give consent. The CT will have no impact on the client's breath sounds or hematocrit and hemoglobin levels. Findings from these assessments will not influence the client's safety during the procedure.
A nurse assesses a client who is recovering from a lumbar puncture (LP). Which complication of this procedure should alert the nurse to urgently contact the health care provider? a. Weak pedal pulses b. Nausea and vomiting c. Increased thirst d. Hives on the chest
ANS: B The nurse should immediately contact the provider if the client experiences a severe headache, nausea, vomiting, photophobia, or a change in level of consciousness after an LP, which are all signs of increased intracranial pressure. Weak pedal pulses, increased thirst, and hives are not complications of an LP.
A nurse is caring for a client with a history of renal insufficiency who is scheduled for a computed tomography scan of the head with contrast medium. Which priority intervention should the nurse implement? a. Educate the client about strict bedrest after the procedure. b. Place an indwelling urinary catheter to closely monitor output. c. Obtain a prescription for intravenous fluids. d. Contact the provider to cancel the procedure
ANS: C If a contrast medium is used, intravenous fluid may be given to promote excretion of the contrast medium. Contrast medium also may act as a diuretic, resulting in the need for fluid replacement. The client will not require bedrest. Although urinary output should be monitored closely, there is no need for an indwelling urinary catheter. There is no need to cancel the procedure as long as actions are taken to protect the kidneys.
A nurse obtains a focused health history for a client who is scheduled for magnetic resonance imaging (MRI). Which condition should alert the nurse to contact the provider and cancel the procedure? a. Creatine phosphokinase (CPK) of 100 IU/L b. Atrioventricular graft c. Blood urea nitrogen (BUN) of 50 mg/dL d. Internal insulin pump
ANS: D Metal devices such as internal pumps, pacemakers, and prostheses interfere with the accuracy of the image and can become displaced by the magnetic force generated by an MRI procedure. An atrioventricular graft does not contain any metal. CPK and BUN levels have no impact on an MRI procedure.
A patient's sudden onset of hemiplegia has necessitated a computed tomography (CT) of her head. Which assessment should the nurse complete prior to this diagnostic study? A. Assess the patient's immunization history. B. Screen the patient for any metal parts or a pacemaker. C. Assess the patient for allergies to shellfish, iodine, or dyes. D. Assess the patient's need for tranquilizers or antiseizure medications.
C Allergies to shellfish, iodine, or dyes contraindicate the use of contrast media in CT. The patient's immunization history is not a central consideration, and the presence of metal in the body does not preclude the use of CT as a diagnostic tool. The need to assess for allergies supersedes the need for tranquilizers or antiseizure medications in the majority of patients.
