NCLEX-RN

NCLEX RN Predictor Exam

1. 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.

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. A 70-year-old man has a blood pressure of 150/90 mm Hg in a lying position, 130/80 mm Hg in a sitting position, and 100/60 mm Hg in a standing position. How should the nurse evaluate these findings?

A. These readings are a normal response and attributable to changes in the patient's position.
B. The change in blood pressure readings is called orthostatic hypotension.
C. The blood pressure reading in the lying position is within normal limits.
D. The change in blood pressure readings is considered within normal limits for the patient's age.

Correct answer: B

Rationale:

4. One of your patients is dependent on a mechanical ventilator for their respiratory needs. The patient cannot breathe on their own. Suddenly, the lights in the patient's room and the entire nursing unit go off. You realize that the electric power has been lost. What is the first thing that you should do for this patient?

A. Plug the ventilator into the red outlet in the room.
B. Plug the ventilator into the blue outlet in the room.
C. Use an Ambu bag to ventilate the patient.
D. Call the doctor about this emergency.

Correct answer: B

Rationale: In healthcare facilities, emergency generators are in place in case of power outages. The red outlets in patient rooms are connected to the emergency generator and provide power during such situations. By plugging the ventilator into the red outlet, you ensure that the patient's mechanical ventilation needs are met despite the power loss. Using an Ambu bag or calling the doctor should be secondary actions after ensuring the ventilator is powered correctly. Plugging the ventilator into the blue outlet is incorrect and can result in the ventilator not functioning during a power outage.

5. 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.
