Nursing Elites

1. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

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

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

2. An adult client tells the clinic nurse that he is susceptible to middle ear infections. About which risk factor related to infection of the ears does the nurse question this client?

• A. Loud music
• B. Use of power tools
• C. Occupational noise
• D. Exposure to cigarette smoke

Correct answer: D

Rationale: The correct answer is 'Exposure to cigarette smoke.' Otitis media (middle ear infection) is associated with various factors like colds, allergies, sore throats, and blockage of the eustachian tubes. Risk factors include exposure to cigarette smoke, youth (as otitis media is usually a childhood disease), congenital abnormalities, immune deficiencies, family history of otitis media, recent upper respiratory infections, and allergies. Choices A, B, and C (Loud music, Use of power tools, and Occupational noise) are more likely to cause hearing loss rather than being direct risk factors for middle ear infections.

3. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

4. A client with Kawasaki disease has bilateral congestion of the conjunctivae, dry cracked lips, a strawberry tongue, and edema of the hands and feet followed by desquamation of fingers and toes. Which of the following nursing measures is most appropriate to meet the expected outcome of positive body image?

• A. administering immune globulin intravenously
• B. assessing the extremities for edema, redness, and desquamation every 8 hours
• C. explaining progression of the disease to the client and their family
• D. assessing heart sounds and rhythm

Correct answer: C

Rationale: Explaining the progression of the disease to the client and their family is the most appropriate nursing measure to promote a positive body image. By educating them about when symptoms are expected to improve and resolve, they can understand that there will be no permanent disruption in physical appearance that could negatively impact body image. While administering immune globulin intravenously may be part of the treatment for Kawasaki disease, it does not directly address body image concerns. Assessing the extremities for edema, redness, and desquamation every 8 hours is important for monitoring the disease but does not directly impact body image. Assessing heart sounds and rhythm is crucial for monitoring cardiac effects of Kawasaki disease but is not directly related to promoting a positive body image.

5. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.
