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. The nurse aspirates 40 mL of undigested formula from the client’s nasogastric tube. Before administering an intermittent tube feeding, the nurse understands that the 40 mL of gastric aspirate should be

• A. Discarded properly and recorded as output on the client’s intake and output record.
• B. Poured into the nasogastric tube through a syringe with the plunger removed.
• C. Mixed with the formula and poured into the nasogastric tube through a syringe with the plunger removed.
• D. Diluted with water and injected into the nasogastric tube by putting pressure on the plunger.

Correct answer: B

Rationale: After checking the residual feeding contents, the gastric contents are reinstalled into the stomach by removing the syringe bulb or plunger and pouring the gastric contents into the syringe and through the nasogastric tube. Gastric contents should be reinstalled to maintain the client’s electrolyte balance. The gastric contents should be poured into the nasogastric tube through a syringe without a plunger and not injected by putting pressure on the plunger. Gastric contents do not need to be mixed with water or should the contents be discarded.

3. Fistulas are most common with which of the following bowel disorders?

• A. Crohn’s disease
• B. Diverticulitis
• C. Diverticulosis
• D. Ulcerative colitis

Correct answer: A

Rationale: Fistulas are most common in Crohn's disease due to the transmural inflammation that characterizes this condition.

4. 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.

5. The 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 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.
