a urine pregnancy test

NCLEX-RN

NCLEX RN Predictor Exam

1. A urine pregnancy test:

A. May be negative even if a blood pregnancy test is positive.
B. Is positive only during the first trimester of pregnancy.
C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
D. All of the above.

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

2. Which of the following vital signs can be expected in a child that is afebrile?

A. Rectal Temp of 100.9 degrees F.
B. Oral Temp of 38 degrees C.
C. Axillary Temp of 98.6 degrees F.
D. All of the above are incorrect.

Correct answer: C

Rationale: The correct answer is the axillary temperature of 98.6 degrees F. Afebrile means without a fever, and an axillary temperature, which is taken in the armpit, is considered normal at 98.6 degrees F. Choice A is incorrect as a rectal temperature of 100.9 degrees F indicates a fever. Choice B is incorrect as an oral temperature of 38 degrees C is also indicative of a fever. Choice D is incorrect as not all options are wrong; only choices A and B are incorrect for an afebrile child.

3. Which nursing intervention is the highest priority for a client at risk for falls in a hospital setting?

A. Keep all of the side rails up
B. Review prescribed medications
C. Complete the "get up and go"? test
D. Place the bed in the lowest position

Correct answer: D

Rationale: The highest priority nursing intervention for a client at risk for falls in a hospital setting is to place the bed in the lowest position. This action ensures that the client falls the shortest distance, reducing the risk of injury. Keeping all side rails up (Option A) may lead to a fall with injury, as the client might attempt to get over the rail and fall from a higher distance. Reviewing prescribed medications (Option B) is important as certain medications can increase the risk of falling, but it is not the best answer as it is not applicable to all clients. Completing the "get up and go"? test (Option C) can help assess a client's risk for falling but does not directly prevent injury.

4. 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.

5. 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.
