NCLEX RN Exam Preview Answers
1. The healthcare provider is reviewing theories of illness. The germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions, is a basic belief of which theory of illness?
- A. Holistic
- B. Biomedical
- C. Naturalistic
- D. Magicoreligious
Correct answer: B
Rationale: The correct answer is B: Biomedical. Among the biomedical explanations for disease is the germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions. The naturalistic or holistic perspective holds that the forces of nature must be kept in natural balance. The magicoreligious perspective holds that supernatural forces dominate and cause illness or health. Therefore, options A, C, and D are incorrect as they do not align with the germ theory explanation provided in the question.
2. In which situation would the nurse use bimanual palpation technique?
- A. Palpating the thorax of an infant
- B. Palpating the kidneys and uterus
- C. Assessing pulsations and vibrations
- D. Assessing the presence of tenderness and pain
Correct answer: B
Rationale: Bimanual palpation involves using both hands to envelop or capture specific body parts or organs like the kidneys, uterus, or adnexa. This technique is particularly useful for assessing the size, shape, consistency, and mobility of deep organs like the kidneys and uterus. Palpating the thorax of an infant (Choice A) is usually done with a different technique like gentle, single-handed palpation. Assessing pulsations and vibrations (Choice C) and assessing tenderness and pain (Choice D) typically do not require the use of bimanual palpation, making Choices A, C, and D incorrect.
3. 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.
4. After performing the appropriate client assessment, which of the following inferences would the nurse make?
- A. Client is hypotensive
- B. Respiratory rate of 20 breaths per minute
- C. Oxygen saturation of 95%
- D. Client relays anxiety about blood work
Correct answer: A
Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.
5. A patient's urine specimen tested positive for bilirubin. Which of the following is most true?
- A. The patient should be evaluated for kidney disease
- B. The specimen was probably left at room temperature for more than two hours
- C. The specimen is positive for bacteria
- D. The specimen should be stored in an area protected from light
Correct answer: D
Rationale: Bilirubin is easily broken down by light, so all samples testing positive for bilirubin should be protected from light exposure. Storing the specimen in an area protected from light helps maintain the integrity of the bilirubin levels for accurate testing. Choice A is incorrect because the presence of bilirubin in urine does not necessarily indicate kidney disease. Choice B is incorrect as the exposure to light, not room temperature, affects bilirubin levels. Choice C is incorrect as the presence of bilirubin does not indicate the presence of bacteria in the specimen.
