Nursing Elites

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. When checking for proper blood pressure cuff size, which guideline is correct?

• A. The standard cuff size is appropriate for all sizes.
• B. The length of the rubber bladder should equal 80% of the arm circumference.
• C. The width of the rubber bladder should equal 80% of the arm circumference.
• D. The width of the rubber bladder should equal 40% of the arm circumference.

Correct answer: D

Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.

3. The Sinoatrial Node (SA) is located within which of the following heart structures?

• A. Mitral Valve
• B. Right Ventricle
• C. Right Atrium
• D. Left Atrium

Correct answer: C

Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.

4. What is an attack using microorganisms such as bacteria or viral agents with the intent to harm others called?

• A. Assimilation
• B. Defense intervention
• C. Bioterrorism
• D. Environmental remediation

Correct answer: C

Rationale: Bioterrorism is the act of using harmful agents like bacteria or viruses with the intention to harm others. In the context of healthcare, nurses may be involved in disaster response if bioterrorism weapons affect the community. Choice A, assimilation, refers to the process of absorbing and integrating information or ideas. Choice B, defense intervention, does not specifically relate to the intentional use of microorganisms to harm others. Choice D, environmental remediation, involves the process of cleaning up pollution or contamination in the environment, which is unrelated to the deliberate use of pathogens for harmful purposes.

5. Efforts by healthcare facilities to reduce the incidence of hospital-acquired infections (HAIs) include an awareness of which of the following?

• A. The CDC requires all states to report HAI rates from each hospital.
• B. Ensure that the restraints are tied to the side rails.
• C. The gastrointestinal tract is a common site for HAIs.
• D. Joint Commission considers death or serious injury from HAIs a sentinel event.

Correct answer: D

Rationale: Efforts to reduce hospital-acquired infections (HAIs) involve being aware that the Joint Commission considers death or serious injury resulting from HAIs a sentinel event, which must be reported. While more than 20 states require reporting of HAI rates to the CDC, it is not a nationwide CDC requirement. The gastrointestinal tract is not a specific common site for HAIs; rather, bacteria are the primary cause. Ensuring restraints are properly secured is important for patient safety but not directly related to reducing HAIs.
