NCLEX RN Predictor Exam

1. The client is a chronic carrier of infection. To prevent the spread of the infection to other clients or healthcare providers, the nurse emphasizes interventions that do which of the following? (Berman & Snyder, 2012, p. 713)

A. Eliminate the reservoir
B. Block the portal of exit from the reservoir
C. Block the portal of entry into the host
D. Decrease the susceptibility of the host

Correct answer: B

Rationale: To prevent the spread of infection from a chronic carrier, the nurse should focus on blocking the portal of exit from the reservoir, which is the carrier person. By preventing the movement of the organism from the reservoir, the infection can be contained. Eliminating the reservoir is not feasible in this case as the carrier is a chronic carrier. Blocking the portal of entry into the host or decreasing the susceptibility of the host would only impact individual prevention and not the spread from the carrier to others.

2. 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.

3. Which of these specific measurements is the best index of a child's general health?

A. Body mass index
B. Height and weight
C. Head circumference
D. Chest circumference

Correct answer: B

Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.

4. What is the purpose of MSDS sheets?

A. Contain the ordering information for each piece of equipment in the office.
B. Are required by OSHA to be accessible to all employees of the office.
C. Can be used to treat patients who have been injured in equipment accidents.
D. None of the above.

Correct answer: B

Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.

5. During a client interview, which of the following leading questions should the nurse avoid asking?

A. What medication do you take at home?
B. You are really excited about the plastic surgery, aren't you?
C. Were you aware I've had this same type of surgery?
D. What would you like to talk about?

Correct answer: B

Rationale: The nurse should avoid asking leading questions during a client interview as they can influence the client's response. Option B is a leading question as it suggests an expected response from the client, potentially biasing the information provided. This can lead to inaccurate data collection and subsequent errors in diagnostic reasoning. Choices A, C, and D are open-ended questions that encourage the client to provide unbiased information and allow for a more comprehensive assessment.
