Nursing Elites

1. How often should the nurse change the intravenous tubing on total parenteral nutrition solutions?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is 'every 24 hours.' Changing the intravenous tubing on total parenteral nutrition solutions every 24 hours is crucial due to the high risk of bacterial growth. Bacterial contamination can lead to serious infections in patients receiving total parenteral nutrition. Choices B, C, and D are incorrect because waiting longer intervals between tubing changes increases the risk of bacterial contamination and infection, compromising patient safety. It is essential to maintain a strict 24-hour schedule to minimize the risk of complications associated with bacterial contamination.

2. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.

3. A nurse assisting with data collection uses the back of the hand to feel the client's skin on both arms and notes that the skin is warm. The nurse makes which determination?

• A. The client has a fever.
• B. The skin temperature is normal.
• C. The client needs to drink additional fluids.
• D. The client needs to have the blanket removed.

Correct answer: B

Rationale: To assess skin temperature, the nurse would first note the temperature of their own hands. Then, using the backs of the hands to palpate the client's skin bilaterally, warmth suggests normal circulatory status if the skin is warm and the temperature is equal bilaterally. The hands and feet may feel slightly cooler in a cool environment. Options A, C, and D are incorrect responses. A warm skin temperature does not indicate a fever, the need for additional fluids, or the need to have the blanket removed.

4. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

5. You are caring for a 78-year-old woman who is wondering why she was diagnosed with glaucoma. Although she has several risk factors, which of these is not one of them?

• A. age
• B. blood pressure reading of 143/89
• C. Mexican-American heritage
• D. 20/80 vision

Correct answer: D

Rationale: Age over 60 and Mexican-American heritage are recognized as risk factors for glaucoma. Elevated blood pressure is also a risk factor due to its potential to cause optic nerve damage. While 20/80 vision indicates poor eyesight, it is not a direct causal factor for glaucoma. Glaucoma is mainly associated with factors like age, ethnicity, and certain medical conditions, rather than a specific visual acuity measurement. Therefore, 20/80 vision is not a risk factor for glaucoma, making it the correct answer. The other choices, such as age, Mexican-American heritage, and elevated blood pressure, are established risk factors for developing glaucoma, as they are associated with an increased likelihood of the condition.
