1. What is a crucial aspect of managing a child with cystic fibrosis?
- A. High-sugar diet
- B. Daily chest physiotherapy
- C. Frequent use of antacids
- D. Limiting fluid intake
Correct answer: B
Rationale: Daily chest physiotherapy is crucial in managing cystic fibrosis as it helps clear mucus from the lungs, improves respiratory function, and reduces the risk of lung infections. High-sugar diets are not recommended for individuals with cystic fibrosis as they can contribute to mucus production, exacerbating respiratory issues. Frequent use of antacids is not a primary treatment for cystic fibrosis, as it does not address the underlying lung issues. Limiting fluid intake is not typically advised for individuals with cystic fibrosis, as adequate hydration is essential for maintaining lung function and thinning mucus secretions.
2. A healthcare professional is collecting data to evaluate a middle adult’s psychosocial development. The healthcare professional should expect middle adults to demonstrate which of the following developmental tasks? (Select all that apply.)
- A. Develop an acceptance of diminished strength and increased dependence on others.
- B. Spend time focusing on improving job performance.
- C. Welcome opportunities to be creative and productive.
- D. Commit to finding friendship and companionship.
Correct answer: B, C, D
Rationale: Middle adulthood is a stage where individuals typically focus on various developmental tasks. Option A is incorrect as middle adults do not necessarily develop an acceptance of diminished strength and increased dependence on others; they often strive to maintain independence. Option B is correct as middle adults are usually focused on improving job performance and advancing their careers. Option C is correct as middle adults tend to welcome opportunities to be creative and productive, engaging in new hobbies or projects. Option D is correct as middle adults often commit to finding friendship and companionship as they value social connections and support networks. Therefore, options B, C, and D are the expected developmental tasks for middle adults, making them the correct choices.
3. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?
- A. To reduce abdominal pressure on the diaphragm
- B. To promote retraction of the intercostal accessory muscles of respiration
- C. To promote bronchodilation and effective airway clearance
- D. To decrease pressure on the medullary center which stimulates breathing
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.
4. What is the most effective therapy for maintaining remission of acute lymphoblastic leukemia?
- A. Surgery to remove enlarged lymph nodes
- B. Long-term chemotherapy
- C. Nutritional supplements to enhance blood cell production
- D. Blood transfusions to replace ineffective red cells
Correct answer: B
Rationale: The correct answer is B: Long-term chemotherapy. Long-term chemotherapy, specifically with methotrexate, is the most effective therapy for maintaining remission in acute lymphoblastic leukemia. Surgery to remove enlarged lymph nodes (Choice A) is not the primary treatment for leukemia. Nutritional supplements (Choice C) may support overall health but are not the mainstay therapy for maintaining leukemia remission. Blood transfusions (Choice D) are used to address anemia in some cases but are not the primary treatment for maintaining remission in acute lymphoblastic leukemia.
5. The nurse is caring for a patient who is immobile and needs to be turned every 2 hours. The patient has poor lower extremity circulation, and the nurse is concerned about irritation of the patient's toes. Which device will the nurse use?
- A. Hand rolls
- B. A foot cradle
- C. A trapeze bar
- D. A trochanter roll
Correct answer: B
Rationale: A foot cradle is the correct choice for this situation. A foot cradle is used to reduce pressure on the tips of a patient's toes in individuals with poor lower extremity circulation. Hand rolls are not designed to address toe irritation specifically. A trapeze bar is used to assist patients with repositioning in bed, and a trochanter roll is used to support the hips and prevent external rotation of the legs, neither of which directly address toe irritation in this scenario.
