Nursing Elites

1. What is the reason for Asthma in 4-year-old Mabele, as Mrs. Joyce Thomson inquires? How would you explain it?

• A. Asthma occurs due to inflammation of the respiratory tract triggered by infections.
• B. An asthmatic attack can occur when the child is exposed to certain allergens, triggering an allergic reaction in the bronchioles that causes bronchial constriction.
• C. An asthmatic attack is a response to the release of inflammatory mediators to epithelial cells, affecting the autonomic neural control of the airway.
• D. Asthma is not an inborn problem; it involves abnormal growth of the bronchial tree causing restriction.

Correct answer: B

Rationale: Asthma in children like Mabele can be triggered by exposure to allergens, leading to an allergic reaction in the bronchioles. This reaction causes constriction of the bronchial tree, resulting in an asthmatic attack. It is essential for caregivers to identify and minimize exposure to these triggers to manage and prevent asthma episodes effectively.

2. Beta-adrenergic agonists such as Salbutamol are given to Reggie, a child with asthma. Such drugs are administered primarily to do which of the following?

• A. Dilate the bronchioles
• B. Reduce secondary infections
• C. Decrease postnasal drip
• D. Reduce airway inflammation

Correct answer: A

Rationale: Beta-adrenergic agonists like Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

3. When evaluating a client's fluid intake and output record, how should fluid intake and urine output relate?

• A. Fluid intake should double the urine output
• B. Fluid intake should be approximately equal to the urine output
• C. Fluid intake should be half the urine output
• D. Fluid intake should be inversely proportional to the urine output

Correct answer: B

Rationale: In assessing a client's fluid intake and output record, it is essential for fluid intake to be approximately equal to the urine output. This balance indicates proper hydration and renal function. Deviations from this balance could signify potential issues that need further investigation and management.

4. A 4-year-old boy ingested an unknown quantity of drain cleaner. He is alert, has a patent airway, and has adequate breathing. You should:

• A. administer 1 g/kg of activated charcoal.
• B. give 15 mL of ipecac and contact medical control.
• C. contact poison control and give him oxygen.
• D. give oxygen and perform a head-to-toe exam.

Correct answer: C

Rationale: When a child ingests a harmful substance like drain cleaner and remains alert with a patent airway and adequate breathing, the initial steps involve contacting poison control to guide further management. In this scenario, providing oxygen to support respiratory function is essential until definitive care is established. Activated charcoal and ipecac are not recommended in the management of ingested caustic substances like drain cleaner. Performing a head-to-toe exam can wait until the child's immediate respiratory needs are addressed and the poison control center has provided guidance on further management.

5. You are treating a 5-year-old child who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. Supplemental oxygen has been given, and you have elevated his lower extremities. En route to the hospital, you note that his work of breathing has increased. You should:

• A. begin positive-pressure ventilations and reassess the child.
• B. lower the extremities and reassess the child.
• C. listen to the lungs with a stethoscope for abnormal breath sounds.
• D. insert a nasopharyngeal airway and increase the oxygen flow.

Correct answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.
