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. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)
- A. 4.2 mL
- B. 5 mL
- C. 3.6 mL
- D. 4 mL
Correct answer: A
Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.
3. A school-age child with a history of type 1 diabetes mellitus is brought to the emergency department with confusion and rapid breathing. The practical nurse (PN) suspects diabetic ketoacidosis (DKA). Which initial intervention should the PN anticipate?
- A. Administer subcutaneous insulin.
- B. Give oral glucose tablets.
- C. Start intravenous fluids.
- D. Administer oxygen therapy.
Correct answer: C
Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.
4. While auscultating the lung sounds of a 5-year-old Chinese boy who recently completed antibiotic therapy for pneumonia, the nurse notices symmetrical, round, bruise-like blemishes on his chest. What action is best for the nurse to take?
- A. Identify the antibiotics used for treating the pneumonia.
- B. Inquire about the use of alternative treatment methods.
- C. Ask the parents if the child has been in a recent accident.
- D. Report suspected child abuse to the authorities.
Correct answer: B
Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.
5. A 7-year-old child with a history of asthma presents to the clinic with shortness of breath and wheezing. The nurse notes that the child’s peak flow reading is in the red zone. What should the nurse do first?
- A. Administer a bronchodilator
- B. Reassess the peak flow reading
- C. Notify the healthcare provider
- D. Provide oxygen therapy
Correct answer: A
Rationale: When a child with asthma presents with shortness of breath and wheezing, and the peak flow reading is in the red zone, indicating severe airflow limitation, the priority intervention is to administer a bronchodilator. Bronchodilators help dilate the airways quickly, improving airflow and assisting with breathing. Reassessing the peak flow reading is important but not the first action to take in a severe asthma exacerbation. Notifying the healthcare provider can be done after initiating immediate treatment with a bronchodilator. Providing oxygen therapy may be needed in some cases, but addressing the airway constriction with a bronchodilator should come first to improve ventilation.
