Nursing Elites

1. The client has undergone a thyroidectomy, and the nurse is providing care. Which assessment finding requires immediate intervention?

• A. Hoarseness and a sore throat.
• B. Difficulty swallowing.
• C. Numbness and tingling around the mouth.
• D. Temperature of 100.2°F (37.9°C).

Correct answer: C

Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a common complication post-thyroidectomy due to inadvertent parathyroid gland removal. Immediate intervention is required to prevent severe hypocalcemia manifestations like tetany or seizures. Hoarseness and a sore throat are common after a thyroidectomy due to surgical trauma and irritation to the vocal cords, not requiring immediate intervention. Difficulty swallowing can be expected due to postoperative swelling or edema, but it should be monitored closely. A temperature of 100.2°F is a mild fever and may be a normal postoperative response, not necessitating immediate intervention unless accompanied by other concerning symptoms.

2. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

3. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?

• A. Wilson's disease
• B. Hemochromatosis
• C. Alpha-1 antitrypsin deficiency
• D. Autoimmune hepatitis

Correct answer: B

Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.

4. The patient described in the preceding question has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?

• A. She is at low risk for reinfection with H. pylori
• B. A positive serum IgG indicates that eradication of H. pylori was successful
• C. The urease breath test is an ideal test to document failure of eradication
• D. Dyspepsia typically worsens with H. pylori eradication

Correct answer: C

Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. The serum IgG may remain positive indefinitely and cannot be used to determine failure of eradication; however, a decrease in quantitative IgG levels has been utilized to indicate treatment success. If available, either the stool antigen or urease breath test is ideal to document treatment failure due to their high sensitivity, specificity, and ease of performance. The relationship between dyspepsia and H. pylori is controversial, but generally, dyspepsia does not typically improve with H. pylori eradication.

5. Which client's laboratory value requires immediate intervention by a nurse?

• A. A client with GI bleeding who is receiving a blood transfusion and has a hemoglobin of 7 grams.
• B. A client with pancreatitis who has a fasting glucose of 190 mg/dl today and had 160 mg/dl yesterday.
• C. A client with hepatitis who is jaundiced and has a bilirubin level that is 4 times the normal value.
• D. A client with cancer who has an absolute neutrophil count < 500 today and had 2,000 yesterday.

Correct answer: D

Rationale: The correct answer is D. A sudden drop in neutrophil count to below 500 indicates severe neutropenia, putting the client at high risk for infections. Neutrophils are essential for fighting off infections, and a significant decrease in their count can compromise the client's immune response. Immediate intervention is necessary to prevent the development of serious infections in the client with neutropenia.
