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. What is the first aid for frostbite?

A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
B. Run warm water over the area to rapidly rewarm the affected area.
C. Run hot water over the area to warm the area as quickly as possible.
D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.

Correct answer: A

Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.

3. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?

A. Asian
B. Hispanic
C. American Indian
D. African American/Black

Correct answer: B

Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.

4. When caring for a single client during one shift, it is appropriate for the nurse to reuse only which of the following personal protective equipment?

A. Goggles
B. Gown
C. Surgical mask
D. Clean gloves

Correct answer: A

Rationale: Goggles may be reused unless they are overly contaminated by material that has splashed in the nurse's face and cannot be effectively rinsed off. Gowns are at high risk for contamination and should be used only once and then discarded or washed. Surgical masks and gloves should never be washed or reused. Goggles provide eye protection from splashes and should be cleaned and disinfected after each use to ensure proper protection.

5. A patient has a goal of eating at least 50% of each meal. The patient refuses to eat, so a nurse force-feeds the patient in order for them to reach their goal of eating at least 50% of the meal. The nurse has committed __________ against this patient.

A. assault
B. battery
C. physical neglect
D. emotional neglect

Correct answer: B

Rationale: The correct answer is 'battery.' Battery occurs when there is unwanted physical contact or force applied to a person without their consent. In this scenario, force-feeding the patient against their will constitutes battery as the nurse is physically interfering with the patient's body without permission. Assault involves the threat of physical harm, which is not present in the situation described. Physical neglect refers to the failure to provide basic care needs, which is not the case here. Emotional neglect involves the failure to address emotional needs, which is also not applicable in this context.
