1. When caring for a child experiencing severe asthma symptoms, which medication should the practical nurse anticipate being administered first?
- A. Inhaled corticosteroids.
- B. Oral corticosteroids.
- C. Short-acting beta agonists.
- D. Leukotriene receptor antagonists.
Correct answer: C
Rationale: In the management of acute asthma exacerbations, the first-line medication for quick relief of bronchoconstriction is a short-acting beta agonist, such as albuterol. These medications help to rapidly open up the airways, providing immediate relief to the patient. Inhaled corticosteroids are more commonly used for long-term control of asthma symptoms, while oral corticosteroids and leukotriene receptor antagonists are often reserved for more severe or chronic cases. Therefore, in a child experiencing severe asthma symptoms, the practical nurse should anticipate the administration of short-acting beta agonists as the initial intervention to provide quick relief and improve breathing.
2. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?
- A. Metabolic alkalosis.
- B. Respiratory acidosis.
- C. Metabolic acidosis.
- D. Respiratory alkalosis.
Correct answer: A
Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
3. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (Proventil) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?
- A. When she last took the antihistamine.
- B. When her last asthma attack occurred.
- C. Duration of most asthma attacks.
- D. How often the MDI is used daily.
Correct answer: D
Rationale: The most important information for the nurse to obtain in this scenario is how often the MDI is used daily. This is crucial to assess if the symptoms the student is experiencing, such as insomnia, shakiness, and tachycardia, could be related to overuse of the inhaler. Overuse of albuterol can lead to side effects like tremors, palpitations, and difficulty sleeping, so understanding the frequency of MDI use is key in determining a potential cause for the student's symptoms. Options A, B, and C are not as pertinent in this situation as they do not directly address the possible link between the student's symptoms and the use of the albuterol MDI.
4. The caregiver is caring for a 2-month-old infant with a diagnosis of bronchiolitis. Which assessment finding would be most concerning to the caregiver?
- A. Nasal flaring and grunting
- B. Coughing and wheezing
- C. Poor feeding and irritability
- D. Increased respiratory rate
Correct answer: A
Rationale: Nasal flaring and grunting are indicative of respiratory distress, suggesting the infant is having difficulty breathing. This finding requires immediate attention as it signifies a more severe respiratory compromise compared to the other symptoms listed.
5. A 6-year-old boy with bronchial asthma takes the beta-adrenergic agonist agent albuterol (Proventil). The child's mother tells the nurse that she uses this medication to open her son's airway when he is having trouble breathing. What is the nurse's best response?
- A. Recommend that the mother bring the child in for immediate evaluation
- B. Advise the mother that overuse of the drug may cause chronic bronchitis
- C. Assure the mother that she is using the medication correctly
- D. Confirm that the medication helps to reduce airway inflammation
Correct answer: C
Rationale: The nurse's priority is to reassure the mother that she is using albuterol correctly to open her son's airways during episodes of difficulty breathing. This reassurance helps build trust and ensures that the child receives the intended benefit of the medication. The answer choice recommending immediate evaluation (A) is not appropriate at this point as the mother is using the medication as prescribed. Advising about overuse causing chronic bronchitis (B) is incorrect and may cause unnecessary alarm. Confirming that the medication helps reduce airway inflammation (D) is not the best response because albuterol is a beta-adrenergic agonist used primarily for bronchodilation in acute asthma exacerbations, rather than for reducing inflammation.
