Nursing Metric Conversions

1. What is 0.4 expressed in inches?

Correct answer: C

Rationale: To express 0.4 in inches, you don't need to convert it further as it is already in inches. Therefore, the correct answer is 0.4 inches. Choice A (0.04 inches) is incorrect as it represents a smaller quantity. Choice B (4 inches) and Choice D (40 inches) are incorrect as they represent larger quantities, which are not equivalent to 0.4 inches.

2. Express the solution to the following problem in decimal form:

Correct answer: C

Rationale: The correct answer is C: 0.84. To convert a percentage to a decimal, you divide the percentage value by 100. In this case, 84% divided by 100 equals 0.84. Choice A, 0.042, is not the correct conversion of 84%. Choice B, 84%, is already in percentage form and needs to be converted to a decimal. Choice D, 0.42, is not the correct conversion of 84% either. Therefore, the correct decimal form of 84% is 0.84.

3. Which of the following properties is NOT characteristic of a covalent bond?

Correct answer: B

Rationale: Covalent bonds are formed by the sharing of electrons between atoms, leading to the formation of molecules with directional bonding. This means that the atoms are held together in a specific orientation. Covalent compounds generally exhibit low melting and boiling points compared to ionic compounds due to the weaker intermolecular forces present in covalent compounds. Furthermore, covalent compounds do not conduct electricity in the solid state because the electrons are localized between the atoms and are not free to move and carry charge. Hence, high melting and boiling points are not characteristic of covalent bonds. The correct answer is 'B' because high melting and boiling points are typically associated with ionic compounds due to their strong electrostatic interactions, while covalent compounds have lower melting and boiling points. Choices A, C, and D are all characteristics of covalent bonds, making them incorrect answers for this question.

4. He also took part in the community police supervision project. He played an instrumental role in the BPP breakfast program for impoverished African American children. Which revision best combines these sentences for clarity and flow?

Correct answer: D

Rationale: The correct answer is 'D' because the phrase 'and played an instrumental role' provides a smoother transition between the two ideas. In this context, using 'and' helps to connect the two activities more effectively. Choice 'B' introduces a contrasting conjunction 'but,' which is not suitable in this context where the actions are related. Choice 'C' incorrectly separates the two actions into distinct sentences, affecting the flow and coherence of the paragraph. Therefore, 'D' is the best choice for combining the sentences for clarity and flow.

5. Which type of immune cell does the human immunodeficiency virus (HIV) target and destroy?

Correct answer: C

Rationale: HIV targets and destroys Helper T cells, which are vital for coordinating the immune response against infections. The destruction of Helper T cells weakens the immune system, leading to acquired immunodeficiency syndrome (AIDS). Neutrophils (Choice A) are primarily involved in acute inflammatory responses and fighting bacterial infections. Macrophages (Choice B) play a role in phagocytosis and antigen presentation but are not the primary target of HIV. Memory B cells (Choice D) are responsible for mounting a quicker and more robust antibody response upon re-exposure to a pathogen, but they are not the main target of HIV infection.
