Nursing Elites

1. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

2. A healthcare professional is reviewing a patient's chart and notices that the patient suffers from Lyme disease. Which of the following microorganisms is related to this condition?

• A. Borrelia burgdorferi
• B. Streptococcus pyogenes
• C. Bacillus anthracis
• D. Enterococcus faecalis

Correct answer: A

Rationale: Lyme disease, the most common vector-borne disease in the United States, is caused by the bacterium Borrelia burgdorferi. Borrelia burgdorferi is transmitted to humans through the bite of infected black-legged ticks. Streptococcus pyogenes is associated with strep throat and other infections, not Lyme disease. Bacillus anthracis causes anthrax, a separate infectious disease. Enterococcus faecalis is more commonly linked to urinary tract infections and other healthcare-associated infections, not Lyme disease.

3. A client is undergoing radiation therapy for treatment of thyroid cancer. Following the radiation, the client develops xerostomia. Which of the following best describes this condition?

• A. Cracks in the corners of the mouth
• B. Peeling skin from the tongue and gums
• C. Increased dental caries
• D. Dry mouth

Correct answer: D

Rationale: Xerostomia, also known as dry mouth, is a common side effect of radiation therapy in the head and neck region. It occurs when the salivary glands are damaged during treatment, reducing saliva production and causing a dry sensation in the mouth. The correct answer is 'Dry mouth' (option D). Choice A, 'Cracks in the corners of the mouth,' describes angular cheilitis, a condition linked to nutritional deficiencies or candida infection. Choice B, 'Peeling skin from the tongue and gums,' is more indicative of conditions like oral thrush or mucositis. Choice C, 'Increased dental caries,' is a consequence of reduced saliva flow but does not specifically describe xerostomia.

4. A mother brings her 26-month-old to the well-child clinic. She expresses frustration and anger due to her child's constant saying 'no' and refusal to follow her directions. The nurse explains this is normal for his age, as negativism is attempting to meet which developmental need?

• A. Trust
• B. Initiative
• C. Independence
• D. Self-esteem

Correct answer: C

Rationale: In Erikson's theory of development, toddlers struggle to assert independence. They often use the word 'no' even when they mean yes. This stage is called autonomy versus shame and doubt. The child's behavior of saying 'no' and resisting directions reflects the developmental need for independence, not trust (option A), initiative (option B), or self-esteem (option D). Trust is typically associated with early infancy, initiative with preschool age, and self-esteem with later childhood and adolescence.

5. Which assessment finding is of most concern for a 46-year-old woman with acute pancreatitis?

• A. Absent bowel sounds
• B. Abdominal tenderness
• C. Left upper quadrant pain
• D. Palpable abdominal mass

Correct answer: D

Rationale: The correct answer is a palpable abdominal mass. In a 46-year-old woman with acute pancreatitis, a palpable abdominal mass may indicate the presence of a pancreatic abscess, which requires rapid surgical drainage to prevent sepsis. Absent bowel sounds, abdominal tenderness, and left upper quadrant pain are common symptoms in acute pancreatitis but do not necessarily indicate an immediate need for surgical intervention. Therefore, the presence of a palpable abdominal mass is the most concerning finding in this scenario.
