Nursing Elites

1. Which of the following conditions can cause a hiatal hernia?

• A. Increased intrathoracic pressure
• B. Weakness of the esophageal muscle
• C. Increased esophageal muscle pressure
• D. Weakness of the diaphragmic muscle

Correct answer: D

Rationale: Weakness of the diaphragmic muscle can lead to a hiatal hernia as it allows part of the stomach to push through the diaphragm into the chest cavity.

2. A 30-year-old woman is admitted to the hospital with complaints of severe abdominal cramping and diarrhea. The nurse evaluates the effectiveness of the patient's intravenous therapy. Which of the following laboratory tests BEST reflects hydration status?

• A. Erythrocyte sedimentation rate.
• B. White blood cell count.
• C. Hematocrit.
• D. Serum glucose.

Correct answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

3. You have to teach ostomy self care to a patient with a colostomy. You tell the patient to measure and cut the wafer:

• A. To the exact size of the stoma.
• B. About 1/16” larger than the stoma.
• C. About 1/8” larger than the stoma.
• D. About 1/4″ larger than the stoma.

Correct answer: C

Rationale: The wafer should be measured and cut about 1/8” larger than the stoma to ensure proper fit and prevent skin irritation.

4. 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.

5. An intubated patient is receiving continuous enteral feedings through a Salem sump tube at a rate of 60ml/hr. Gastric residuals have been 30-40ml when monitored Q4H. You check the gastric residual and aspirate 220ml. What is your first response to this finding?

• A. Notify the doctor immediately.
• B. Stop the feeding, and clamp the NG tube.
• C. Discard the 220ml, and clamp the NG tube.
• D. Give a prescribed GI stimulant such as metoclopramide (Reglan).

Correct answer: B

Rationale: If gastric residuals are high during continuous enteral feedings, the first response is to stop the feeding and clamp the NG tube.
