1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?

• A. Keeping the door to the client's room closed
• B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
• C. Placing the client in a semiprivate room with a cohort client
• D. Using a surgical mask when entering the client's room

Correct answer: A

Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.

3. Which of the following NSAIDs is most commonly used for a brief period for acute pain?

• A. Advil
• B. Aleve
• C. Toradol
• D. Bextra

Correct answer: C

Rationale: Toradol is the correct answer because it is an NSAID known for its effectiveness in managing acute pain for short durations. It can be administered via intramuscular (IM), intravenous (IV), or oral (PO) routes. Advil (choice A) and Aleve (choice B) are commonly used for mild to moderate pain but may not be as effective for acute pain requiring immediate relief. Bextra (choice D) was withdrawn from the market due to safety concerns, making it an inappropriate choice for acute pain management.

4. Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be:

• A. Outbreak of Asian flu.
• B. Chemical exposure.
• C. Bacterial pneumonia.
• D. Allergic reaction.

Correct answer: B

Rationale: The most likely cause of groups of individuals suddenly experiencing similar signs of illness all at once is a chemical exposure. In this scenario, considering the sudden onset of symptoms in multiple passengers on an airliner, the symptoms are more indicative of a chemical exposure rather than Asian flu, bacterial pneumonia, or an allergic reaction. Asian flu, bacterial pneumonia, and allergic reactions do not typically manifest in a way that would affect a group of individuals simultaneously. Therefore, the correct diagnosis in this case is likely to be a chemical exposure.

5. When should the biohazard emblem be affixed to containers according to the orientation nurse educator reviewing the biohazard legend with a class of new employees?

• A. when there is presence of blood and body fluids.
• B. when there is the need for droplet precautions.
• C. when there is contact isolation.
• D. when there is the potential for airborne transmission.

Correct answer: A

Rationale: The correct answer is 'when there is presence of blood and body fluids.' When handling body substances like blood and body fluids, the risk of transmission of infections increases. Federal regulations mandate warning labels on containers to alert employees and waste collectors. The biohazard emblem consists of a three-ring symbol overlaying a central concentric ring. Blood, wound drainage, feces, and urine are examples of body fluids that can transmit infections and diseases to others. The other choices, B, C, and D, are incorrect because the presence of the biohazard emblem is specifically linked to the handling of blood and body fluids, not to droplet precautions, contact isolation, or airborne transmission.
