NCLEX RN Predictor Exam

1. 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.

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. Which of the following actions can help prevent a fire in the area where a healthcare professional works?

A. Using an adaptor when plugging in client equipment
B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
D. Keeping extra equipment stored in one area with other supplies and materials

Correct answer: C

Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.

4. Which statement best describes evidence-based practice?

A. Reading and analyzing research reports to determine their implementation in nursing practice
B. Collecting data to evaluate the efficiency of nursing practice in delivering quality care
C. Monitoring unit practices to ensure adherence to Joint Commission standards
D. Using the most effective, current, and applicable information to guide nursing care for the best outcomes

Correct answer: D

Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.

5. The nurse suspects that a client is withholding health-related information out of fear of discovery and possible legal problems. The nurse formulates nursing diagnoses for the client carefully, being concerned about a diagnostic error resulting from which of the following?

A. Incomplete data
B. Generalizing from experience
C. Identifying with the client
D. Lack of clinical experience

Correct answer: A

Rationale: In this scenario, the nurse is cautious about potential diagnostic errors due to incomplete data. When a client withholds information, it can lead to incomplete data, which may result in inaccurate nursing diagnoses and care planning. Therefore, the nurse's primary concern is collecting accurate data to make informed clinical decisions. Choices B, C, and D are not relevant to the situation described. Generalizing from experience, identifying with the client, and lack of clinical experience do not directly address the issue of incomplete data impacting the diagnostic process.
