Nursing Elites

1. The NFPA diamond has four colors. The blue diamond:

• A. indicates hazards to health.
• B. designates that it is safe to use water to put out this type of fire.
• C. indicates that ice is necessary to treat an injury with this type of chemical.
• D. indicates that the chemical may be incinerated upon disposal.

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.

2. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?

• A. Controls stray electrical currents.
• B. Promotes efficient use of electricity.
• C. Shuts off the appliance if there is an electrical surge.
• D. Divides the electricity among the appliances in the room.

Correct answer: A

Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.

3. Which playroom activities should the nurse organize for a small group of 7-year-old hospitalized children?

• A. Sports and games with rules.
• B. Finger paints and water play.
• C. "Dress-up"? clothes and props.
• D. Chess and television programs

Correct answer: A

Rationale: For 7-year-old children, play serves an important role in developing cooperation, logical reasoning, and social skills. Organizing sports and games with rules is beneficial as it helps children understand the importance of rules, promotes teamwork, and fosters social interactions. Finger paints and water play, while fun, may not target the specific developmental needs of this age group. Similarly, 'Dress-up' clothes and props can encourage imaginative play but may not necessarily promote cooperation and logical reasoning. Chess and television programs are more suited for older children and may not engage 7-year-olds as effectively in developing the desired skills.

4. What procedure examines a portion of the large intestine with an endoscope?

• A. Colposcopy
• B. Sigmoidoscopy
• C. Upper GI
• D. Cardiac catheterization

Correct answer: B

Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.

5. When evaluating the temperature of older adults, what aspect should the healthcare provider remember about an older adult's body temperature?

• A. The body temperature of the older adult is lower than that of a younger adult.
• B. An older adult's body temperature is approximately the same as that of a young child.
• C. Body temperature varies based on the type of thermometer used.
• D. In older adults, body temperature can fluctuate widely due to less effective heat control mechanisms.

Correct answer: A

Rationale: When evaluating the temperature of older adults, it is important to note that their body temperature is usually lower than that of younger adults, with a mean temperature of 36.2�C. Choice B is incorrect because an older adult's body temperature is not approximately the same as that of a young child. Choice C is incorrect because body temperature is a physiological parameter and does not vary based on the type of thermometer used. Choice D is incorrect because while older adults may have less effective heat control mechanisms, their body temperature is typically lower, not widely fluctuating.
