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. A healthcare professional realizes after a patient has left the office that they forgot to document the patient's complaint of a sore throat. Which of the following choices would BEST correct the error?

A. Pull out that page of the chart and rewrite it with the correct information.
B. Put one line through the original Chief Complaint, write 'ERROR,' your initials, and today's date. Make the correction by rewriting the Chief Complaint with the correct information.
C. Go to the next available line of the SOAP notes. Write the current date, then write 'Late Entry.' Place the date and time when the patient stated they had a sore throat. Sign and date the entry.
D. All of the above are incorrect.

Correct answer: C

Rationale: When adding information to a patient's chart after the encounter, using the term 'Late Entry' is essential. This clearly indicates that the information was added after the fact and helps to maintain the accuracy and integrity of the medical record. Option A is incorrect because removing a page from the chart and rewriting it can lead to inaccuracies and is not a recommended practice for correcting errors. Option B suggests marking the original Chief Complaint as an error, which may not be clear to future readers of the chart and could lead to confusion. Option D is incorrect as it dismisses the correct approach outlined in Option C, which is the best way to handle the situation of missed documentation during a patient encounter.

3. When assessing a pulse, what should be noted?

A. Rate
B. Rate and quality
C. Rate, quality, and fullness
D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.

4. As a valued member of the team on your nursing care unit, you are trying to determine whether the team is doing well. Which of the following is a sign that your team is successful?

A. Conflict occurs but is seen as an opportunity for team growth and development.
B. No negative feelings are expressed, leading to everyone being happy and satisfied.
C. Mistakes are not tolerated and result in disciplinary action.
D. People avoid taking risks and stick to the status quo.

Correct answer: A

Rationale: One of the key indicators of a successful team is the ability to handle conflict positively. Conflict, when managed well, can lead to team growth and development. Choice B is incorrect because suppressing negative feelings does not indicate team success; open communication is crucial. Choice C is incorrect as successful teams view mistakes as learning opportunities rather than resorting to disciplinary action. Choice D is incorrect because successful teams are often innovative and willing to take risks rather than maintaining the status quo.

5. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

A. "The numbers are within the normal range and are nothing to worry about."?
B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.
