1. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

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. A patient who is displaying the defense mechanism of Compensation would:

A. Refuse to hear unwanted information.
B. Transfer feelings of negativity to someone else.
C. Overemphasize behaviors which accommodate for perceived weaknesses.
D. Place blame on others for personal actions or mistakes.

Correct answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings. Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

4. A client who complains of nausea and seems anxious is admitted to the nursing unit. The nurse should take which of the following actions regarding completion of the admission interview?

A. Help the client to get settled and conduct the interview the next morning when the client is rested
B. Conduct the interview immediately, directing the majority of the questions to the client
C. Conduct the interview as soon as uninterrupted time is available to address the client's concerns
D. Ask the charge nurse to interview the client while the admitting nurse calls the doctor for anti-nausea and anti-anxiety medication

Correct answer: C

Rationale: When dealing with a client who is experiencing nausea and anxiety, it is important to promptly conduct the admission interview to address their concerns. This allows for the collection of accurate data while attending to the client's immediate needs. Delaying the interview until the next morning (Choice A) may not be in the best interest of the client as timely assessment and intervention are essential. Directing questions to the client's spouse (Choice B) may not provide accurate information from the client themselves. Asking another nurse to conduct the interview while administering medications (Choice D) does not prioritize building a therapeutic relationship with the client, which is crucial in addressing their concerns and providing holistic care.

5. Digestion, elimination, and ___________ are the three functions of the digestive system.

A. constriction
B. relaxation
C. absorption
D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.
