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. During a heritage assessment, which question is most appropriate for the nurse to ask?

A. "Do you smoke?"?
B. "What is your religion?"?
C. "Do you have a history of heart disease?"?
D. "How many years have you lived in the United States?"?

Correct answer: D

Rationale: During a heritage assessment, it is crucial for the nurse to ask questions related to a person's country of ancestry, years in the United States, cultural practices, beliefs, and values. By asking about the number of years lived in the United States, the nurse can gain insights into the individual's cultural background and heritage. Options B, C, and A are not directly related to assessing heritage. Asking about religion only addresses one aspect of heritage, while smoking history and health history do not provide a comprehensive view of a person's heritage.

3. While percussing over the liver of a patient, the nurse notices a dull sound. What should the nurse do?

A. Consider this a normal finding
B. Palpate this area for an underlying mass
C. Reposition the hands and attempt to percuss in this area again
D. Consider this finding as abnormal and refer the patient for additional treatment

Correct answer: A

Rationale: When percussing over relatively dense organs, such as the liver or spleen, a dull sound is a normal finding due to the organ's density. This occurs because the sound waves produced by tapping on the organ travel through the dense tissue, resulting in a dull sound. Therefore, the correct action for the nurse in this scenario is to consider a dull sound over the liver as a normal finding. Palpating for an underlying mass (Choice B) is not indicated based on the percussion finding alone. Repositioning the hands and repeating the percussion (Choice C) may not change the dull sound over the liver. Referring the patient for additional treatment (Choice D) without understanding the normal percussion findings over the liver would be premature. Thus, the most appropriate action is to interpret the dull sound as a normal finding.

4. Which of the following is the correct sequence for removing personal protective equipment?

A. Remove gown, gloves, shoe covers, mask
B. Remove mask, gloves, gown, shoe covers
C. Remove gloves, gown, mask, shoe covers
D. Remove shoe covers, mask, gloves, gown

Correct answer: C

Rationale: The correct sequence for removing personal protective equipment is crucial to prevent contamination. When exiting a surgical or aseptic situation, the proper sequence is to first remove gloves, followed by the gown, mask, and finally shoe covers. This order ensures that potentially contaminated items are removed first, minimizing the risk of exposure. Choice A, 'Remove gown, gloves, shoe covers, mask,' is incorrect as gloves should be removed before the gown. Choice B, 'Remove mask, gloves, gown, shoe covers,' is incorrect as gloves should be removed first. Choice D, 'Remove shoe covers, mask, gloves, gown,' is incorrect as gloves should be the first item removed to prevent contamination.

5. Which of the following is an example of physical abuse?

A. A slap to the person's hand
B. Threatening the person
C. Ignoring and isolating a person
D. Leaving a patient soiled for hours

Correct answer: A

Rationale: The correct answer is 'A slap to the person's hand.' Slapping, hitting, and punching are clear examples of physical abuse. Physical abuse involves actions that can cause physical harm or injury to a person. Choice B, 'Threatening the person,' falls under the category of emotional or psychological abuse, where threats can cause fear and emotional distress but do not involve physical harm. Choice C, 'Ignoring and isolating a person,' is a form of neglect or emotional abuse, not physical abuse. Choice D, 'Leaving a patient soiled for hours,' is an example of neglect or lack of proper care, which is also not classified as physical abuse.
