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 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.

3. In which of the following ways can a nurse promote sleep for a client experiencing insomnia?

A. Assist the client in using the bathroom one hour after going to bed
B. Give the client a massage before bedtime
C. Tuck bed sheets and blankets tightly around the client once settled in bed
D. Give the client a pair of socks to wear if their feet become cold

Correct answer: D

Rationale: A nurse can promote sleep for a client experiencing insomnia by addressing factors that may hinder sleep. Cold feet can disrupt sleep, so providing the client with socks to keep their feet warm can enhance comfort and aid in promoting sleep. The correct answer focuses on a direct intervention to address a specific issue that can impact sleep quality. Choices A, B, and C do not directly address the issue of cold feet, which is a common problem that can interfere with sleep in individuals with insomnia. Assisting the client to use the bathroom, giving a massage in the morning, or tucking in bed sheets tightly do not target the discomfort caused by cold feet, making them less effective interventions for promoting sleep in this scenario.

4. What would be an appropriate evaluation statement for the nurse to write based on the client's ability to state only two signs of impaired circulation out of three as expected?

A. Client understands the signs of impaired circulation
B. Goal met: Client cited numbness and tingling as a sign of impaired circulation
C. Goal not met: Client able to name only two signs of impaired circulation
D. Goal not met: Client unable to describe signs of impaired circulation

Correct answer: C

Rationale: The appropriate evaluation statement for the nurse to write would be 'Goal not met: Client able to name only two signs of impaired circulation.' In this scenario, the client has only identified two out of the three signs of impaired circulation specified in the desired outcome. Therefore, the goal has not been fully achieved. It is essential in nursing practice to assess and document client progress accurately. While the client has shown some understanding by correctly identifying numbness and tingling as signs of impaired circulation, the inability to state the third sign indicates an incomplete achievement of the goal. This evaluation helps guide further interventions or educational strategies to help the client meet the desired outcome in the care plan.

5. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.
