Nursing Elites

1. A nurse is discussing sources of vitamin K with a client. Which food should the nurse recommend?

• A. Fish
• B. Leafy greens
• C. Citrus fruits
• D. Nuts

Correct answer: B

Rationale: Leafy greens are rich in vitamin K, which is important for blood clotting.

2. Of the following neurotransmitters, which demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways?

• A. Serotonin
• B. Enkephalin
• C. Norepinephrine
• D. Acetylcholine

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

• A. Take the blood pressure reading on both arms for comparison
• B. Listen to and identify the phases of Korotkoff sounds
• C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
• D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.

4. Which of the following conditions is not caused by energy drinks?

• A. Nervousness
• B. Bradycardia
• C. Seizures
• D. Dental caries

Correct answer: B

Rationale: Energy drinks are known for causing a variety of health issues, including nervousness, seizures, and an increased risk of dental caries due to their high sugar content. However, they do not cause bradycardia, which is a slow heart rate. Instead, energy drinks are associated with causing an increased or rapid heart rate, known as tachycardia. Therefore, out of the listed options, bradycardia is the condition not caused by energy drinks.

5. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

• A. 5
• B. 5.5
• C. 6
• D. 6.5

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.
