1. The healthcare provider writes several prescriptions for a client diagnosed with hospital-acquired pneumonia (HAP) that include a combination of broad-spectrum antibiotics. Which intervention should the nurse implement first?
- A. Administer the first dose of antibiotics.
- B. Obtain a chest X-ray.
- C. Administer oxygen therapy.
- D. Collect blood specimens for culture prior to starting antibiotic therapy.
Correct answer: D
Rationale: Collecting blood specimens for culture prior to starting antibiotic therapy is the priority intervention in a client diagnosed with hospital-acquired pneumonia. This step is crucial to identify the causative organism responsible for the infection and ensure that the antibiotics prescribed are appropriate for effective treatment. Administering antibiotics before collecting cultures may interfere with the accuracy of culture results, potentially leading to inappropriate treatment. While administering the first dose of antibiotics is important, obtaining a chest X-ray and administering oxygen therapy are secondary interventions compared to identifying the causative organism through blood cultures.
2. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
3. Methotrexate is prescribed for a client with rheumatoid arthritis (RA) who is also taking aspirin. What is the best explanation for the nurse to provide as to why a second medication has been added?
- A. Methotrexate slows the disease progression while aspirin controls the symptoms.
- B. Methotrexate helps to reduce the side effects of aspirin.
- C. Methotrexate has fewer harmful side effects than aspirin.
- D. Methotrexate enhances the effect of aspirin.
Correct answer: A
Rationale: The correct answer is A. Methotrexate is a disease-modifying antirheumatic drug (DMARD) that slows the progression of rheumatoid arthritis (RA), while aspirin helps control symptoms such as pain and inflammation. Therefore, the combination of methotrexate and aspirin is beneficial in managing RA by addressing both disease progression and symptom control. Choices B, C, and D are incorrect because methotrexate is not added to reduce the side effects of aspirin, has different side effects compared to aspirin, and does not enhance the effect of aspirin.
4. What could suddenly occur in a child with acute epiglottitis?
- A. Increased carbon dioxide levels
- B. Airway obstruction
- C. Inability to swallow
- D. Bronchial collapse
Correct answer: B
Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.
5. An unlicensed assistive personnel (UAP) reports to the nurse that a client with a postoperative wound infection has a temperature of 103.8°F, blood pressure 90/70, pulse 124 beats/min, and respirations of 28 breaths/min. When the nurse assesses the client's findings, they include a mottled skin appearance and confusion. Which action should the nurse take first?
- A. Obtain a wound specimen for culture.
- B. Initiate an infusion of intravenous (IV) fluids.
- C. Transfer the client to the ICU.
- D. Assess the client's core temperature.
Correct answer: B
Rationale: The correct action for the nurse to take first is to initiate an infusion of intravenous (IV) fluids. In this scenario, the client is showing signs of sepsis, indicated by a high temperature, low blood pressure, rapid heart rate, and increased respiratory rate. Mottled skin appearance and confusion are also signs of poor perfusion. Initiating IV fluids is crucial in treating sepsis to maintain blood pressure and perfusion. Obtaining a wound specimen for culture (Choice A) can be important but is not the priority at this moment. Transferring the client to the ICU (Choice C) can be considered after stabilizing the client. Assessing the client's core temperature (Choice D) is not the immediate priority compared to addressing the signs of sepsis and poor perfusion.
