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 statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?

A. ''This action of my lips helps to keep my airway open.''
B. ''I can expel more air when I pucker up my lips to breathe out.''
C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''

Correct answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

3. Who is most likely to arrange the discharge of a patient to their own home, a nursing home, or an assisted living facility?

A. A physical therapist
B. A speech therapist
C. A social worker
D. An occupational therapist

Correct answer: C

Rationale: Social workers play a crucial role in arranging patient discharges to suitable facilities. They collaborate with healthcare professionals to ensure that patients are transitioned to the most appropriate setting post-hospitalization. Social workers focus on the holistic needs of patients, including their social and emotional well-being, to facilitate a smooth continuum of care. Choices A, B, and D do not typically have the primary responsibility for arranging patient discharges to various facilities.

4. When is the best time for the nurse to attempt to elicit the Moro reflex during an infant examination?

A. When the infant is sleeping
B. At the end of the examination
C. Before auscultation of the thorax
D. At about the middle of the examination

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, is best elicited at the end of the examination because it can cause the infant to cry. This reflex is triggered by a sudden change in position or loud noise, and it involves the infant's arms extending and then coming back together as if embracing. By eliciting this reflex at the end of the examination, the nurse can observe the infant's response and ensure that the examination is completed without unnecessary distress. Choices A, C, and D are incorrect because the Moro reflex is typically elicited at the end of the examination to avoid disrupting the assessment process and causing unnecessary discomfort to the infant.

5. The abbreviation ac is defined as _____________.

A. before the meal
B. with the meal
C. after the meal
D. ante cibum

Correct answer: A

Rationale: The correct answer is 'before the meal.' The abbreviation 'ac' is derived from the Latin term 'ante cibum,' which translates to 'before a meal.' Choices B, C, and D are incorrect because 'ac' does not refer to 'with the meal,' 'after the meal,' or 'ante corpis.' It specifically denotes something occurring before a meal, making option A the correct choice in this context.
