CLINICAL JUDGMENT CASE STUDY ASSESSMENT JULY
2026 (QUESTIONS and ANSWERS)
1. A 72-year-old patient is admitted with community-acquired
pneumonia. Which assessment finding would be most indicative
of a need for ICU-level care, according to the 2019 ATS/IDSA
guidelines?
A. Respiratory rate of 26 breaths per minute
B. Confusion with a Glasgow Coma Scale (GCS) score of 14
C. Need for non-invasive ventilation due to persistent hypoxemia
D. Blood pressure of 100/60 mmHg responding to a 500 mL fluid
bolus
Correct Answer: C
Explanation: The 2019 ATS/IDSA guidelines identify the need for
invasive or non-invasive ventilation as a major criterion for severe
CAP, indicating ICU admission. Minor criteria (e.g., RR >30,
confusion, hypotension requiring fluids) suggest consideration but
are not sole indicators for ICU-level care.
2. A 68-year-old male with a history of COPD presents with
worsening dyspnea. His ABG on room air shows: pH 7.28, PaCO2
68 mmHg, PaO2 55 mmHg, HCO3 30 mEq/L. Which nursing
intervention is a priority?
A. Administer a high-flow oxygen mask at 15 L/min
B. Prepare for immediate endotracheal intubation
C. Apply BiPAP ventilation with close monitoring
, D. Position the patient in a high Fowler's position and encourage
pursed-lip breathing
Correct Answer: C
Explanation: The patient's ABG indicates acute-on-chronic
respiratory acidosis (low pH, high PaCO2, elevated HCO3). Non-
invasive positive pressure ventilation (BiPAP) is the first-line
therapy to support ventilation and prevent intubation in COPD
exacerbations without immediate indications for intubation. High-
flow oxygen can suppress the hypoxic drive; intubation is indicated
if BiPAP fails or the patient is unstable.
3. A 45-year-old patient is one day post-operative following an open
cholecystectomy. Which finding requires immediate intervention?
A. Pain score of 7/10 at the incision site
B. Heart rate of 98 bpm and blood pressure 148/90 mmHg
C. Urine output of 25 mL/hr for the last three hours
D. Mild erythema around the surgical dressing
Correct Answer: C
Explanation: A urine output of <30 mL/hr for two consecutive
hours suggests acute kidney injury (AKI) or hypovolemia, requiring
immediate assessment of fluid status and potential intervention.
Pain, tachycardia/hypertension, and mild erythema are expected
post-operative findings but should be monitored and managed.
4. A patient with heart failure has a pulmonary artery catheter in
place. The nurse notes the following hemodynamic parameters:
Cardiac Output (CO) 3.2 L/min, Cardiac Index (CI) 1.7 L/min/m²,
, Systemic Vascular Resistance (SVR) 1800 dynes·sec/cm⁵, and
Pulmonary Capillary Wedge Pressure (PCWP) 22 mmHg. Which
intervention is most appropriate?
A. Administer a vasopressor to increase SVR
B. Administer a diuretic to reduce preload
C. Administer a vasodilator to reduce afterload
D. Administer a positive inotrope to improve contractility
Correct Answer: D
Explanation: The patient has a low CI (<2.2 L/min/m²) with high
PCWP (indicating fluid overload). This indicates cardiogenic shock
with impaired contractility. An inotrope (e.g., dobutamine,
milrinone) will improve contractility and increase CO. Vasopressors
would worsen afterload; diuretics address fluid but not
contractility; vasodilators could drop blood pressure excessively.
5. In a patient with severe sepsis, the nurse reviews the lactate level.
What is the primary clinical significance of a persistently elevated
lactate despite fluid resuscitation?
A. Indicates the patient is responding well to antibiotics
B. Suggests the need for increased crystalloid fluid administration
C. Indicates possible inadequate tissue perfusion or ongoing
anaerobic metabolism
D. Is a normal finding due to the stress response and requires no
intervention
Correct Answer: C
Explanation: Persistently elevated lactate (>2 mmol/L) after
adequate fluid resuscitation is a hallmark of tissue hypoperfusion
and anaerobic metabolism in sepsis. It indicates the need for a
, reassessment of the patient's hemodynamic status and possible
escalation of care, such as initiation of vasopressors or inotropes.
It does not indicate a good response, nor is it a benign finding.
6. A 56-year-old female is receiving a continuous infusion of
norepinephrine for septic shock. The intravenous (IV) site in her
right arm appears pale and cool compared to the left. What is the
priority nursing action?
A. Document the finding and continue to monitor
B. Apply a warm compress to the affected arm
C. Stop the infusion and restart it at a different site
D. Slow the infusion rate and reassess in 15 minutes
Correct Answer: C
Explanation: The pale, cool appearance of the extremity indicates
extravasation or vasoconstriction from norepinephrine, which can
lead to tissue ischemia and necrosis. The priority is to stop the
infusion and restart it in a different, healthy IV site, ideally a
central line. Warm compresses may worsen the ischemia by
increasing metabolic demand; slowing the infusion does not
address the compromised site.
7. A patient is admitted with an exacerbation of heart failure and has
a past medical history of renal insufficiency. The provider orders
furosemide (Lasix) 80 mg IV push. Which lab value should the
nurse check before administering this medication?
A. Serum sodium
B. Serum potassium
