Nursing Elites

1. Which of the following is NOT a recommended method for preventing healthcare-associated infections (HAIs)?

• A. Handwashing with soap and water
• B. Proper use of personal protective equipment (PPE)
• C. Disinfecting and reusing sterile medical devices
• D. Using single-use sterile medical devices

Correct answer: C

Rationale: Disinfecting and reusing sterile medical devices is not a recommended method for preventing healthcare-associated infections (HAIs). Reusing sterile medical devices can increase the risk of infections due to inadequate sterilization or potential damage to the devices during the reprocessing process. Proper sterilization and disposal of single-use medical devices are essential in preventing the transmission of infections in healthcare settings. A) Handwashing with soap and water is a crucial method for preventing HAIs as it helps to remove and reduce the number of pathogens on the hands of healthcare workers, preventing the spread of infections. B) Proper use of personal protective equipment (PPE) such as gloves, gowns, masks, and eye protection is important in preventing the transmission of infections between patients and healthcare workers. C) Disinfecting and reusing sterile medical devices is not a recommended practice as it can lead to the transmission of infections if the devices are not adequately sterilized. Using single-use sterile medical devices helps to ensure that each patient receives a sterile device, reducing the risk of infections.

2. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

3. Which of the following organs is responsible for filtering waste from the blood?

• A. Liver
• B. Kidneys
• C. Pancreas
• D. Heart

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.

4. What is the relationship between the frequency and period of a wave?

• A. They are unrelated
• B. Frequency = Period
• C. Frequency = 1/Period
• D. Period = 1/Frequency

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This relationship indicates that the period of a wave is the reciprocal of its frequency. Frequency refers to the number of complete cycles of a wave occurring in a unit of time, while the period is the time taken for one complete cycle of the wave to occur. As frequency and period are inversely related, the correct formula to express this relationship is Period = 1/Frequency. Choice A is incorrect as frequency and period are related. Choice B is incorrect as frequency and period are not equal. Choice C is incorrect as it suggests that frequency is directly proportional to period, which is not the case.

5. Which part of the neuron receives signals from other neurons?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: B

Rationale: The correct answer is B, Dendrite. Dendrites are the part of the neuron that receive signals from other neurons and transmit them to the cell body. Axons transmit signals away from the cell body, synapse is the junction between neurons where neurotransmitters are released, and myelin sheath is a fatty layer that insulates and speeds up signal conduction along the axon. Therefore, choices A, C, and D are incorrect in the context of receiving signals from other neurons.
