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: May be negative even if a blood pregnancy test is positive.

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. When preparing a patient on complete bed rest to eat, at what degree angle or more should you put the head of the bed up?

A. 10
B. 15
C. 20
D. 30

Correct answer: D

Rationale: The correct answer is D: 30. When a patient is on complete bed rest, it is essential to elevate the head of the bed at a 30-degree angle or more before meals. This position helps prevent choking and aspiration of food during eating by promoting proper swallowing and digestion. Choices A, B, and C are incorrect because they do not provide the optimal elevation needed to support safe and effective feeding for a patient on complete bed rest.

3. Which action is appropriate for the nurse to delegate to unlicensed assistive personnel (UAP)?

A. Listen to a patient's lung sounds for wheezes or rhonchi.
B. Label specimens obtained during percutaneous lung biopsy.
C. Instruct a patient about how to use home spirometry testing.
D. Measure induration at the site of a patient's intradermal skin test.

Correct answer: Label specimens obtained during percutaneous lung biopsy.

Rationale: Labeling specimens obtained during a percutaneous lung biopsy is a task that can be appropriately delegated to unlicensed assistive personnel (UAP) as it does not require nursing judgment. UAP can perform this task safely under the supervision of a nurse. Listening to a patient's lung sounds for wheezes or rhonchi, instructing a patient about how to use home spirometry testing, and measuring induration at the site of a patient's intradermal skin test all require nursing judgment and interpretation of findings. These tasks should be performed by licensed nursing personnel to ensure accurate assessment and appropriate intervention.

4. When should you wear gloves?

A. preparing infant formula for a newborn baby
B. transferring breast milk into a baby bottle
C. knocking on a patient's door
D. opening a patient's door

Correct answer: transferring breast milk into a baby bottle

Rationale: You must wear gloves when transferring breast milk into a baby bottle because breast milk is considered a bodily fluid. It is essential to avoid direct contact to prevent contamination. When preparing infant formula, gloves are not required as formula is not a bodily fluid. Knocking on or opening a patient's door does not involve direct contact with bodily fluids, so gloves are unnecessary in those situations.

5. Your patient has finished a 12-ounce can of iced tea and 8 ounces of fresh orange juice. What will you record on the Intake and Output form for this patient's intake?

A. 20 cc
B. 20 cm
C. 600 cc
D. 600 cm

Correct answer: 600 cc

Rationale: You will record 600 cc of fluid intake. There are 600 cc in 20 ounces (12 ounces of iced tea + 8 ounces of orange juice) of fluid intake. Choice A and B are incorrect as they do not reflect the correct conversion of fluid intake from ounces to cubic centimeters. Choice D is incorrect as it provides the measurement in cubic centimeters but does not account for the total fluid intake accurately.
