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. All of the following factors may contribute to client falls EXCEPT:

A. Contact dermatitis
B. Urinary frequency
C. Decreased visual acuity
D. Confusion

Correct answer: A

Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.

3. During a work shift, how can a nurse best demonstrate the dynamic nature of the nursing process?

A. Collaborating with the client to establish healthcare goals
B. Reviewing the client's medical record history
C. Explaining the purpose of administered medications to the client
D. Rapidly resetting priorities for client care based on changes in the client's condition

Correct answer: D

Rationale: The nursing process is dynamic as it involves adapting to the changing health status of the client. Rapidly resetting priorities for client care based on changes in the client's condition exemplifies this dynamic nature by responding promptly to evolving circumstances. Collaborating with the client to establish healthcare goals (Option A), reviewing the client's medical record history (Option B), and explaining the purpose of administered medications to the client (Option C) are all essential nursing actions but do not directly showcase the dynamic nature of the nursing process.

4. Which of the following sets of word parts means 'Pain'?

A. dynia and -algia
B. a- and an
C. ia and -ac
D. pathy and -osis

Correct answer: A

Rationale: The correct answer is 'dynia and -algia.' The word parts 'dynia' and '-algia' specifically relate to pain. 'Dynia' refers to pain, and '-algia' also denotes pain. Therefore, when combined, they form the meaning 'pain.' Choices B, C, and D are incorrect because 'a-' and 'an' do not relate to pain, 'ia' and '-ac' do not specifically convey pain, and 'pathy' and '-osis' are not word parts that directly signify pain.

5. Which is the most effective action for controlling the spread of infection?

A. Thorough hand hygiene
B. Wearing gloves and masks when providing direct client care
C. Implementing appropriate isolation precautions
D. Administering broad-spectrum prophylactic antibiotics

Correct answer: A

Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.
