Nursing Elites

1. A nurse is caring for an older client who has a bronchopulmonary infection. The nurse monitors the client's ability to maintain a patent airway because of which factor involved in the normal aging process?

• A. Increased respiratory system compliance
• B. Decreased number of alveoli and increased function of those remaining
• C. Decreased older client's ability to clear secretions
• D. Increased production of surfactant

Correct answer: C

Rationale: The correct answer is 'Decreased older client's ability to clear secretions.' Respiratory changes related to the normal aging process decrease an older adult's ability to clear secretions and protect the airway. In healthy older adults, the number of alveoli does not change significantly; their structure, however, is altered. Respiratory system compliance decreases with advancing age because of a progressive loss of elastic recoil of the lung parenchyma and conducting airways, and reduced elastic recoil of the lung and opposing forces of the chest wall. Production of surfactant in the lung does not usually decrease with aging, nor does it increase. However, the production of alveolar cells responsible for surfactant production is diminished. Choices A, B, and D are incorrect. Choice A is incorrect because respiratory system compliance decreases with aging. Choice B is incorrect as the number of alveoli does not significantly decrease in healthy older adults. Choice D is incorrect as the production of surfactant does not usually decrease with aging.

2. Which of the following physical findings indicates that an 11-12-month-old child is at risk for developmental dysplasia of the hip?

• A. refusal to walk
• B. not pulling to a standing position
• C. negative Trendelenburg sign
• D. negative Ortolani sign

Correct answer: B

Rationale: The correct answer is 'not pulling to a standing position.' If an 11-12-month-old child is unable to pull to a standing position, it can indicate a risk for developmental dysplasia of the hip. By 15 months of age, children should be walking, so delayed standing can be a red flag. The Trendelenburg sign is associated with gluteus medius muscle weakness, not hip dysplasia, making choice C incorrect. The Ortolani sign is used to detect congenital hip subluxation or dislocation, not developmental dysplasia, making choice D incorrect.

3. The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?

• A. "I take my Lipitor with a glass of milk after my breakfast."?
• B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
• C. "I take my Lipitor 30 minutes after I eat something."?
• D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?

Correct answer: D

Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.

4. 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.

5. The LPN receives a call from a mother caring for her eight-month-old infant. The mother describes that the child has a low-grade fever and has teeth breaking through the gums. Which of the following measures would be inappropriate to recommend to the mother?

• A. Allow the child to chew on a cooled teething ring.
• B. Massage the child's gums gently.
• C. Administer acetaminophen.
• D. Administer aspirin.

Correct answer: D

Rationale: Administering aspirin would be inappropriate in this situation. Aspirin should not be recommended for children due to the increased risk of Reye's syndrome, a serious condition. Choices A, B, and C are all appropriate measures for managing teething discomfort in infants. Allowing the child to chew on a cooled teething ring can help soothe the gums, massaging the child's gums gently can provide relief, and administering acetaminophen is a suitable option for pain relief in infants with teething discomfort. Aspirin is contraindicated in children with viral infections due to the risk of Reye's syndrome, a potentially fatal condition affecting the brain and liver. Therefore, recommending aspirin to the mother would not be appropriate in this case.
