1. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

2. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

• A. urinalysis
• B. creatinine and blood urea nitrogen
• C. chemistry of electrolytes
• D. creatinine clearance

Correct answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

3. An LPN is having a conflict with another nurse during her shift. She has tried to discuss the issues with the nurse with no resolution. What is the most appropriate way for the LPN to proceed?

• A. Report the conflict to the director of nursing over the unit.
• B. Report the conflict to the assigned charge nurse of the unit.
• C. Report the conflict to the nurse manager of the unit.
• D. Discuss the conflict with the other nurse to attempt resolution of the issue.

Correct answer: B

Rationale: In this scenario, the most appropriate way for the LPN to proceed is to report the conflict to the assigned charge nurse of the unit. Following the chain of command is crucial in a professional setting to address conflicts effectively. Reporting the issue to the charge nurse, who is the immediate supervisor, allows for a structured approach to resolving the conflict. Reporting directly to higher levels such as the director of nursing or nurse manager may bypass the appropriate hierarchy and could create unnecessary tension. Attempting to resolve the issue independently with the other nurse may not be effective if previous attempts have failed, making it essential to involve the immediate supervisor.

4. Which cultural group has the highest incidence of inflammatory bowel disease (IBD)?

• A. Asians
• B. Caucasians
• C. Hispanics
• D. African Americans

Correct answer: B

Rationale: The correct answer is Caucasians. Studies have shown that Caucasians have the highest incidence of inflammatory bowel disease (IBD) compared to other cultural groups. While IBD can affect individuals from various backgrounds, the prevalence is notably higher in Caucasians. Asians, Hispanics, and African Americans have a lower incidence of IBD compared to Caucasians, making them incorrect choices in this context.

5. What condition is mammography used to detect?

• A. pain
• B. tumor
• C. edema
• D. epilepsy

Correct answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.
