Nursing Elites

1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. After a class on culture and ethnicity, the new graduate nurse reflects a correct understanding of the concept of ethnicity with which statement?

• A. "Ethnicity is dynamic and ever-changing."?
• B. "Ethnicity is the belief in a higher power."?
• C. "Ethnicity pertains to a social group that may possess shared traits such as religion and language."?
• D. "Ethnicity is learned from birth through the processes of language acquisition and socialization."?

Correct answer: C

Rationale: Ethnicity pertains to a social group that may possess shared traits such as common geographic origin, migratory status, religion, language, values, traditions, or symbols and food preferences. Culture is dynamic, ever-changing, and learned from birth through the processes of language acquisition and socialization. Religion is the belief in a higher power. Ethnicity pertains to a social group within the social system that claims to have variable traits, such as a common geographic origin, migratory status, religion, race, language, values, traditions, symbols, or food preferences.

3. The nurse should wash from the ________________________ when washing a patient's eye area.

• A. outer canthus to the inner canthus
• B. inner canthus to the outer canthus
• C. internal nares to the external nares
• D. external nares to the internal nares

Correct answer: B

Rationale: When washing a patient's eye area, it is important to start from the inner canthus (closest to the nose) and move towards the outer canthus. This direction prevents any contaminants or debris from the outer area of the eye from moving towards the inner, more sensitive area. Choices C and D are incorrect as they pertain to the nasal passages (nares), which are not relevant when washing the eye area.

4. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?

• A. Behavior
• B. Cognition
• C. Affect and mood
• D. Perceptual disturbances

Correct answer: B

Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.

5. When checking for proper blood pressure cuff size, which guideline is correct?

• A. The standard cuff size is appropriate for all sizes.
• B. The length of the rubber bladder should equal 80% of the arm circumference.
• C. The width of the rubber bladder should equal 80% of the arm circumference.
• D. The width of the rubber bladder should equal 40% of the arm circumference.

Correct answer: D

Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.
