1. A client is scheduled for oral cholecystography. Which one of the following actions would the nurse plan to implement before the test?
- A. Have the client drink 1000 mL of water.
- B. Ask the client about possible allergies to iodine or shellfish.
- C. Administer an intravenous contrast agent the evening before the test.
- D. Administer tap-water enemas until clear.
Correct answer: B
Rationale: Iodine compounds used as radiographic contrast agents, such as iopanoic acid (Telepaque), should not be administered to the client with iodine and seafood allergies because anaphylaxis may occur.
2. Which of the following symptoms best describes Murphy’s sign?
- A. Periumbilical ecchymosis exists
- B. On deep palpation and release, pain is elicited
- C. On deep inspiration, pain is elicited and breathing stops
- D. Abdominal muscles are tightened in anticipation of palpation
Correct answer: C
Rationale: Murphy's sign is described as pain elicited on deep inspiration when the examiner's fingers are placed under the right costal margin.
3. A home care nurse is visiting a client with a diagnosis of pernicious anemia that developed as a result of gastric surgery. The nurse instructs the client that because the stomach lining produces a decreased amount of intrinsic factor in this disorder, the client will need
- A. Vitamin B12 injections.
- B. Vitamin B6 injections.
- C. An antibiotic.
- D. An antacid.
Correct answer: A
Rationale: A lack of the intrinsic factor needed to absorb vitamin B12 occurs in pernicious anemia. Vitamin B12 is needed for the maturation of red blood cells. Vitamin B6 is not necessarily needed for pernicious anemia and can be taken orally. An antibiotic and antacids may be prescribed for certain types of gastric ulcers.
4. A nurse orientee is preparing to insert a nasogastric tube, and a nurse educator is observing the procedure. Which of the following supplies if obtained by the nurse orientee would indicate a need for further education regarding this procedure?
- A. Half-inch or one-inch tape
- B. Oil-soluble lubricant
- C. A glass of tap water with a straw
- D. A 50-mL catheter tip syringe
Correct answer: B
Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.
5. Hepatic encephalopathy develops when the blood level of which substance increases?
- A. Ammonia
- B. Amylase
- C. Calcium
- D. Potassium
