Nursing Elites

1. Cocaine is derived from the leaves of coca plant; the nurse knows that cocaine is classified as:

• A. Narcotic
• B. Stimulant
• C. Barbiturate
• D. Hallucinogen

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

2. Overdosage of medication or anesthetic can happen even with the aid of technology like infusion pumps, sphygmomanometer, and similar devices/machines. As a staff member, how can you improve the safety of using infusion pumps?

• A. Check the functionality of the pump before use
• B. Select the brand of infusion pump carefully
• C. Allow the technician to set the infusion pump before use
• D. Verify the flow rate against your calculation

Correct answer: D

Rationale: To enhance the safety of using infusion pumps, it is crucial to verify the flow rate against your calculation. This step ensures that the prescribed dosage is being delivered accurately, reducing the risk of medication errors. Checking the functionality of the pump before use (Choice A) is also important to ensure it is working properly. Allowing the technician to set the pump (Choice C) may not always guarantee the correct settings. Selecting the brand of infusion pump carefully (Choice B) is not directly related to the safe use of the pump.

3. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

4. A nurse in a prenatal clinic is educating a client about expected changes during pregnancy. The nurse should instruct the client about which change during pregnancy is related to the slowing of the gastrointestinal tract?

• A. Diarrhea
• B. Constipation
• C. Decreased absorption of iron
• D. Decreased absorption of calcium

Correct answer: B

Rationale: During pregnancy, the hormonal changes can lead to the slowing down of the gastrointestinal tract, causing constipation. This occurs due to increased progesterone levels, which relax smooth muscles, including those in the intestines, leading to slower bowel movements. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. While there may be changes in the absorption of nutrients like iron and calcium, they are not directly related to the slowing of the gastrointestinal tract.

5. Which is NOT a characteristic or function of lipids?

• A. Involved in energy metabolism and storage
• B. Provide insulation and protection
• C. Act as hormones that regulate the body
• D. Are hydrophilic

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
