Solved: Critical Thinking about Patient Data and Making Informed Decisions

Case Scenario 1 – Pneumonia


As a nurse you will be required to think critically about patient data and make informed decisions. In this case scenario you will apply what you've learned in the previous modules to the following concepts (if applicable):
  • Clinical decision making
  • Safety Considerations
  • Collaboration
  • Patient assessment
  • Pathophysiology
  • Nutrition
  • Medication Administration
Upon completion of this activity, the student will be able to:
  1. Apply their knowledge of pharmacokinetics and the physiological changes across the lifespan to actual clinical situations.
  2. Understand and describe the nursing responsibility involving pharmacological interventions


  1. Read the assignment rubric to understand how you will be graded.
  2. Answer the case scenario questions using your textbook and scholarly, recent (within the last five years) nursing articles. Be sure to address any of the above concepts that apply to the scenario.
  3. Complete the concept map according to the case scenario. A concept map template is provided for you, but you can edit it to fit the case scenario as you see fit. Be sure map all medications and show relationships between the concepts listed above if it's applicable to the scenario. 
  4. Upload your concept map answer document to the assignment page.

Case Scenario

An 85-year-old female with history of hypertension presented with cough and low-grade fever. Chest radiography is consistent with a diagnosis of pneumonia.  The doctor ordered the antibiotic Levofloxacin 500 mg PO X 10 days. The patient’s blood work came back, and basic metabolic panel showed potassium (K) of 5 mmol/L, sodium (NA) 140 mmol/L, glucose of 115, BUN of 19 mg/dl and creatinine of 1.2 mg/dl. Questions:
  1. In your understanding of the physiological changes in the elderly, what predisposes them to respiratory infections?
  2. In considering the different physiological changes in the elderly, what considerations are crucial in determining the correct drugs and dosage of medications to be ordered? What drug class does levofloxacin belong to, and is this drug appropriate as ordered?  In looking at this case scenario, is there any reason for concern that the primary care provider needs to be aware of?
  3. Using a concept map, provide a graphic representation of the pharmacological agent ordered. Include the patient’s diagnosis and symptoms, the drug class, generic name, most common brand names in the market, nursing considerations, and adverse effects. A concept map template is provided for you. Edit it to fit the case scenario as you see fit.
