1. The parents of a 6-year-old recently diagnosed with asthma should be taught that symptoms of an acute episode of asthma are due to which physiological response?
- A. Inflammation of the mucous membrane and bronchospasm
- B. Increased mucus production and airway obstruction
- C. Hyperinflation of the lungs and alveolar collapse
- D. Bronchoconstriction and airway inflammation
Correct answer: D
Rationale: The correct answer is D: Bronchoconstriction and airway inflammation. During an acute asthma episode, bronchoconstriction and airway inflammation occur, leading to difficulty breathing. Choices A, B, and C are incorrect. Inflammation of the mucous membrane and bronchospasm (Choice A) are part of the pathophysiology of asthma but do not fully explain the symptoms during an acute episode. Increased mucus production and airway obstruction (Choice B) are also seen in asthma but are not the primary cause of acute symptoms. Hyperinflation of the lungs and alveolar collapse (Choice C) are not typical features of an acute asthma episode.
2. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?
- A. Serum glucose of 600 mg/dL
- B. Serum osmolarity of 320 mOsm/kg
- C. Serum sodium of 130 mEq/L
- D. Serum potassium of 5.0 mEq/L
Correct answer: B
Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
3. The nurse is assessing a 1-year-old child with bronchiolitis caused by respiratory syncytial virus (RSV). Which assessment finding requires immediate intervention?
- A. Wheezing heard on expiration
- B. Oxygen saturation of 90%
- C. Respiratory rate of 40 breaths per minute
- D. Nasal flaring with sternal retractions
Correct answer: D
Rationale: Nasal flaring with sternal retractions indicates severe respiratory distress in a 1-year-old with bronchiolitis, requiring immediate intervention. Nasal flaring and sternal retractions are signs of increased work of breathing and decreased air movement, indicating the child is struggling to breathe. Wheezing on expiration (Choice A) is common in bronchiolitis but may not require immediate intervention. An oxygen saturation of 90% (Choice B) is low but may not be the most critical finding in this case. A respiratory rate of 40 breaths per minute (Choice C) is elevated but alone may not indicate the need for immediate intervention as much as nasal flaring and sternal retractions.
4. A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?
- A. Obtain the results for STAT serum cardiac biomarkers.
- B. Assess for contraindications for thrombolytic therapy.
- C. Measure ST-segment height and waveform changes.
- D. Transfer for percutaneous coronary intervention (PCI).
Correct answer: B
Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.
5. A male client with ulcerative colitis received a prescription for a corticosteroid last month, but because of the side effects, he stopped taking the medication 6 days ago. Which finding warrants immediate intervention by the nurse?
- A. Anxiety and restlessness
- B. Increased bowel movements
- C. Abdominal cramping
- D. Fever and chills
Correct answer: A
Rationale: The correct answer is A: Anxiety and restlessness. Abruptly stopping corticosteroids can cause adrenal insufficiency, leading to symptoms such as anxiety and restlessness. These symptoms indicate a potential serious complication that requires immediate intervention. Increased bowel movements and abdominal cramping are common side effects of ulcerative colitis and may not warrant immediate intervention. Fever and chills are not typically associated with adrenal insufficiency caused by corticosteroid withdrawal.
