NCLEX RN Exam Review Answers

1. What is the expected date of delivery for your pregnant client when her last menstrual period was on 10/20/2016

A. 7/7/2017
B. 8/7/2017
C. 6/7/2017
D. 8/1/2017

Correct answer: A

Rationale: The expected date of delivery is calculated using Nagle's rule which is: The first day of last menstrual period - 3 months + 7 days = the estimated date of delivery

2. The nurse is caring for a woman 2 hours after a vaginal delivery. Documentation indicates that the membranes were ruptured for 36 hours prior to delivery. What are the priority nursing diagnoses at this time?

A. Altered tissue perfusion
B. Risk for fluid volume deficit
C. High risk for hemorrhage
D. Risk for infection

Correct answer: D

Rationale: The correct answer is 'Risk for infection.' When membranes are ruptured for over 24 hours before delivery, there is a significantly increased risk of infection for both the mother and the newborn. Factors such as increased local cytokines, an imbalance in enzyme activity, and increased intrauterine pressure contribute to this risk. 'Altered tissue perfusion' is not the priority in this scenario as there is no indication of compromised blood flow. 'Risk for fluid volume deficit' is not the priority as there are no signs of excessive fluid loss. 'High risk for hemorrhage' is not the priority as the question does not suggest active bleeding as an immediate concern.

3. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

A. External light sources may cause falsely high oximetry values
B. A bright light in the client's face may cause a low pulse oximetry
C. External light sources may cause falsely low oximetry values
D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

4. Which of the following is a function of risk management?

A. To consider the problems that arise if errors happen and their effects on the healthcare environment
B. To identify how nursing care responds to specific client problems
C. To view clients as customers and decide what actions will provide a satisfying healthcare experience
D. To analyze physician-nurse relationships and determine where collaboration efforts can improve

Correct answer: A

Rationale: The function of risk management in healthcare is to assess and address potential risks that could lead to errors and their effects on the healthcare environment. This involves identifying, evaluating, and prioritizing risks to minimize their impact and prevent adverse outcomes. Choice A is correct because it aligns with the core purpose of risk management in healthcare. Choices B, C, and D are incorrect as they do not directly relate to the primary focus of risk management, which is the proactive management of risks to ensure patient safety and quality care.

5. The key to the prevention of a pandemic influenza is:

A. Early detection
B. Early antibiotic treatment
C. Vaccination of at-risk populations
D. Isolation of suspected cases

Correct answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.
