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. 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.

3. A pregnant client is being educated by a nurse on nutrition and foods rich in folic acid. Which food item does the nurse inform the client contains the highest amount of folic acid?

• A. Pinto beans
• B. Lettuce
• C. Oranges
• D. Broccoli

Correct answer: A

Rationale: Pinto beans contain the highest amount of folic acid among the options provided, with 294 mcg per 1-cup serving. Oranges contain 44 mcg per 1-cup serving, lettuce contains 60 mcg per 1-cup serving, and broccoli contains 78 mcg per 1-cup serving. Therefore, pinto beans are the best choice for increasing folic acid intake during pregnancy. Choosing oranges, lettuce, or broccoli would not provide as much folic acid compared to pinto beans, making them less optimal choices for meeting folic acid requirements during pregnancy.

4. When obtaining a health history on a menopausal woman, which information should a nurse recognize as a contraindication for hormone replacement therapy?

• A. family history of stroke
• B. ovaries removed before age 45
• C. frequent hot flashes and/or night sweats
• D. unexplained vaginal bleeding

Correct answer: D

Rationale: When considering hormone replacement therapy for a menopausal woman, unexplained vaginal bleeding should be recognized as a contraindication. This is because it could be indicative of a serious underlying condition that needs investigation before initiating hormone therapy. A family history of stroke, by itself, is not a contraindication for hormone replacement therapy, unless the woman herself has a history of stroke or blood-clotting events. Ovaries removed before age 45 may actually increase the likelihood of needing hormone replacement therapy due to early menopause. Frequent hot flashes and night sweats, on the other hand, are symptoms that can be relieved by hormone replacement therapy, making them a potential indication rather than a contraindication.

5. When removing hard contact lenses from an unresponsive client, what should the nurse do?

• A. Gently irrigate the eye with an irrigating solution from the inner canthus outward.
• B. Grasp the lens with a gentle pinching motion.
• C. Don sterile gloves before attempting the procedure.
• D. Ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens.

Correct answer: D

Rationale: When removing hard contact lenses, it is crucial to ensure that the lens is correctly positioned on the cornea before removal. Directly grasping the lens can potentially scratch the cornea, so it is essential to gently manipulate the lids to release the lens safely. Gently irrigating the eye is unnecessary and could be harmful, especially without the client's cooperation. Wearing sterile gloves is also unnecessary for this specific procedure. Therefore, the correct approach is to ensure the proper positioning of the lens and then gently manipulate the lids to release it. Options A and C are incorrect because irrigating the eye and wearing sterile gloves are not necessary for contact lens removal. Option B is incorrect as directly grasping the lens can be harmful to the cornea.
