1. After performing the appropriate client assessment, which of the following inferences would the nurse make?

• A. Client is hypotensive
• B. Respiratory rate of 20 breaths per minute
• C. Oxygen saturation of 95%
• D. Client relays anxiety about blood work

Correct answer: A

Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.

2. 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.

3. All of the following factors may contribute to client falls EXCEPT:

• A. Contact dermatitis
• B. Urinary frequency
• C. Decreased visual acuity
• D. Confusion

Correct answer: A

Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.

4. Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?

• A. One light blue, one red
• B. Two lavenders
• C. One lavender, one grey
• D. One green, one red

Correct answer: D

Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.

5. During a class on the aspects of culture, the instructor shares that culture has four basic characteristics. Which statement correctly reflects one of the characteristics of culture?

• A. Static and unchanging
• B. Members sharing similar physical characteristics
• C. Members sharing a common geographic origin and religion
• D. Adapted to specific conditions related to environmental and technical factors

Correct answer: D

Rationale: Culture has four basic characteristics, one of which is that it is adapted to specific conditions related to environmental and technical factors and to the availability of natural resources. The other three characteristics are: (1) learned from birth through the processes of language acquisition and socialization; (2) shared by all members of the cultural group; and (3) dynamic and ever-changing. Culture is not static and unchanging but is dynamic and ever-changing. Members of a culture do not necessarily share similar physical characteristics; that refers to race. Similarly, members of a culture do not necessarily share a common geographic origin and religion; that refers to ethnicity.
