1. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?

• A. Asian
• B. Hispanic
• C. American Indian
• D. African American/Black

Correct answer: B

Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.

2. The mitral valve is synonymous with the term:

• A. Left ventricle
• B. Right atrium
• C. Bicuspid valve
• D. Tricuspid valve

Correct answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

3. A patient is asked to abduct her arms. Which of the following accurately describes her arm movement?

• A. She moves her arms away from her trunk
• B. She moves her arms toward her trunk
• C. She rotates her arms at the wrists while holding them away from her body
• D. She crosses her arms over her abdomen

Correct answer: A

Rationale: Abduction refers to moving a body part away from the midline of the body. In this case, when the patient abducts her arms, she is moving them away from her trunk. Choice A is correct. Choices B, C, and D are incorrect. Choice B describes adduction, which is the movement of a body part toward the midline. Choice C describes wrist rotation, not arm abduction. Choice D describes crossing the arms over the abdomen, which is not the movement associated with abduction.

4. When are manual hematocrits done?

• A. to monitor anemia
• B. by using a microhematocrit tube.
• C. to measure the percentage of plasma to cells.
• D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

5. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?

• A. Often used to direct light into the sinuses
• B. Used to examine the structures of the internal ear
• C. Uses a short, broad speculum to help visualize the ear
• D. Directs light into the ear canal and onto the tympanic membrane

Correct answer: D

Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.
