Nursing Elites

1. A nurse is instructing teenage girls on the importance of adequate calcium intake throughout their life span to prevent complications. Which complication should the nurse include in the teaching?

• A. Goiter
• B. Osteoporosis
• C. Heart disease
• D. Dental caries

Correct answer: B

Rationale: The correct answer is B: Osteoporosis. Adequate calcium intake throughout life helps prevent osteoporosis, a condition characterized by weak and brittle bones, which is common in older adults. Goiter is caused by an iodine deficiency, not calcium. Heart disease is more related to factors like cholesterol and blood pressure. Dental caries are primarily influenced by oral hygiene and sugar intake, not just calcium.

2. With which type of cancer is asbestos exposure most strongly associated?

• A. Liver cancer
• B. Peritoneal cancer
• C. Skin cancer
• D. Esophageal cancer

Correct answer: B

Rationale: Asbestos exposure is most strongly associated with peritoneal cancer, a type of cancer that affects the lining of the abdomen. While asbestos can potentially contribute to other types of cancer, there is a significant body of research indicating a robust correlation between asbestos exposure and peritoneal cancer. Asbestos exposure can also lead to mesothelioma, a cancer that affects the lining of the chest. The other options - liver cancer, skin cancer, and esophageal cancer - are not typically associated with asbestos exposure.

3. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

4. Sickle cell disease is an example of an inherited mistake in the amino acid sequence.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.

5. Before and after the operation, the operating suite is managed by the:

• A. Surgeon C. Nurse Manager
• B. Nurse Supervisor D. Chief Nurse
• C.
• D.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
