Nursing Elites

1. Which of the following organs does not belong with the others?

• A. Thyroid gland
• B. Stomach
• C. Intestines
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.

2. A patient's body is not properly filtering blood. Which of the following body parts is most likely malfunctioning?

• A. Medulla
• B. Heart
• C. Nephrons
• D. Renal cortex

Correct answer: C

Rationale: Nephrons are the functional units of the kidneys responsible for filtering blood and removing waste products to form urine. If a patient's body is not properly filtering blood, it is most likely due to dysfunction or impairment in the nephrons of the kidneys. The heart is responsible for pumping blood, not filtering it, making choice B incorrect. The medulla and renal cortex are specific parts of the kidney but do not directly perform the filtration function carried out by the nephrons, making choices A and D incorrect.

3. Acids are generally characterized by a sour taste and the ability to:

• A. Turn litmus paper red
• B. Conduct electricity in solution
• C. Neutralize bases
• D. React explosively with metals

Correct answer: C

Rationale: Acids are known for their sour taste and their ability to neutralize bases, which is a defining characteristic of their acidic nature. When acids neutralize bases, salts and water are formed, highlighting the unique property of acids. The other options are incorrect: Option A, 'Turn litmus paper red,' is a test for acidity but not a defining characteristic of acids; Option B, 'Conduct electricity in solution,' pertains to the electrolytic properties of acids rather than their defining trait; Option D, 'React explosively with metals,' is not a general characteristic of acids. Therefore, the correct feature associated with acids is their capability to neutralize bases, making option C, 'Neutralize bases,' the correct answer.

4. Where would a nonpregnant patient with normal anatomy most commonly have pain in acute appendicitis?

• A. Right upper quadrant.
• B. Left upper quadrant.
• C. Right lower quadrant.
• D. Left lower quadrant.

Correct answer: C

Rationale: In acute appendicitis, nonpregnant patients with normal anatomy commonly experience pain in the right lower quadrant of the abdomen. The pain usually starts around the umbilicus or epigastric area and then migrates to the right lower quadrant as inflammation progresses in the appendix. This classic migration of pain is known as McBurney's point tenderness and is a key clinical feature in diagnosing appendicitis.

5. What term describes the front of the body, for example, the kneecap?

• A. Posterior
• B. Anterior
• C. Superior
• D. Inferior

Correct answer: B

Rationale: The correct answer is 'B: Anterior.' In anatomy, 'anterior' refers to the front of the body, like the kneecap. On the other hand, 'posterior' describes the back of the body. Choices 'C: Superior' and 'D: Inferior' relate to structures being above or below a reference point, respectively, and are not used to describe the front or back of the body. Therefore, 'Anterior' is the most appropriate term given the context provided in the question.
