Patient Care Exams and Clinical Competency Assessments
Question 1: A 72-year-old patient is admitted with a diagnosis of sepsis secondary to a
urinary tract infection. The patient's blood pressure is 88/52 mmHg, heart rate is 118 bpm,
respiratory rate is 24/min, and temperature is 39.2°C. Which of the following is the priority
nursing intervention?
A. Administer oral antibiotics as prescribed
B. Apply a cooling blanket to reduce fever
C. Obtain a urine culture and sensitivity
D. Initiate a fluid resuscitation bolus as prescribed
CORRECT ANSWER: D. Initiate a fluid resuscitation bolus as prescribed
Rationale: The patient is displaying signs of septic shock with hypotension and tachycardia. The
priority intervention in sepsis-induced hypotension is to initiate early fluid resuscitation with
crystalloids to restore intravascular volume and improve tissue perfusion. While obtaining
cultures and administering antibiotics are critical steps, they should follow the immediate
stabilization of hemodynamics with fluid therapy.
Question 2: A nurse is caring for a patient with diabetic ketoacidosis (DKA). Which of the
following laboratory findings is the most indicative of this condition?
A. Serum glucose 180 mg/dL and pH 7.38
B. Serum bicarbonate 10 mEq/L and blood glucose 450 mg/dL
C. Serum potassium 5.5 mEq/L and BUN 15 mg/dL
D. Serum pH 7.35 and pCO2 48 mmHg
CORRECT ANSWER: B. Serum bicarbonate 10 mEq/L and blood glucose 450 mg/dL
,Rationale: DKA is characterized by hyperglycemia (blood glucose >250 mg/dL), metabolic
acidosis (pH <7.3, bicarbonate <15 mEq/L), and ketonemia. Option B correctly represents
severe hyperglycemia accompanied by a critically low bicarbonate level, indicating significant
acid-base imbalance.
Question 3: A patient post-myocardial infarction develops sudden shortness of breath,
crackles in the lung bases, and pink frothy sputum. Which medication should the nurse
prepare to administer first to manage this condition?
A. Furosemide
B. Morphine sulfate
C. Nitroglycerin
D. Oxygen via non-rebreather mask
CORRECT ANSWER: D. Oxygen via non-rebreather mask
Rationale: The patient is presenting with signs of acute pulmonary edema, likely due to left-
sided heart failure. The immediate priority is to correct hypoxemia to prevent further tissue
hypoxia. High-flow oxygen via a non-rebreather mask should be applied first to maximize
oxygenation, followed by pharmacological interventions.
Question 4: A patient with chronic obstructive pulmonary disease (COPD) is receiving oxygen
via nasal cannula at 2 L/min. Which arterial blood gas (ABG) finding would indicate that the
current oxygen therapy is appropriate?
A. PaO2 55 mmHg, PaCO2 60 mmHg
B. PaO2 68 mmHg, PaCO2 48 mmHg
C. PaO2 85 mmHg, PaCO2 35 mmHg
D. PaO2 92 mmHg, PaCO2 72 mmHg
CORRECT ANSWER: B. PaO2 68 mmHg, PaCO2 48 mmHg
Rationale: For patients with COPD, the goal of oxygen therapy is to maintain a PaO2 of 60-70
mmHg to avoid suppressing the hypoxic drive. Option B reflects a safe PaO2 level while
maintaining a PaCO2 that is not critically elevated, indicating adequate ventilation without
significant hypercapnia.
Question 5: A nurse is preparing to administer a blood transfusion to a patient with anemia.
Which of the following actions should the nurse take to ensure patient safety?
,A. Infuse the blood over 30 minutes to prevent bacterial growth
B. Use a microaggregate filter for all blood products
C. Verify the patient's identity using two unique identifiers
D. Administer the blood through a port containing dextrose solution
CORRECT ANSWER: C. Verify the patient's identity using two unique identifiers
Rationale: Verification of patient identity using at least two unique identifiers (e.g., name and
date of birth) is the most critical safety step to prevent transfusion errors and hemolytic
reactions. Blood should be infused over 2-4 hours, filters are specific to products, and dextrose
solutions should never be administered simultaneously with blood.
Question 6: A patient with liver cirrhosis is exhibiting confusion, asterixis, and a flapping
tremor. Which dietary modification is most appropriate for this patient?
A. High-protein diet to promote muscle mass
B. Low-protein diet to reduce ammonia production
C. High-sodium diet to prevent fluid shifts
D. Low-carbohydrate diet to prevent hyperglycemia
CORRECT ANSWER: B. Low-protein diet to reduce ammonia production
Rationale: The symptoms indicate hepatic encephalopathy caused by elevated ammonia levels
due to the liver's inability to convert ammonia to urea. A low-protein diet is prescribed to
decrease ammonia production from protein metabolism in the gut. However, protein
restriction is moderate to prevent malnutrition.
Question 7: The nurse is assessing a patient with a chest tube connected to a water-seal
drainage system. Which finding indicates an air leak in the system?
A. Continuous bubbling in the water-seal chamber
B. Tidaling in the water-seal chamber with respirations
C. Constant drainage of 200 mL in the collection chamber
D. Gentle bubbling in the suction control chamber
CORRECT ANSWER: A. Continuous bubbling in the water-seal chamber
Rationale: Continuous bubbling in the water-seal chamber indicates an air leak in the system,
which could be from the patient's chest or the chest tube connection. Tidaling is a normal
finding, and bubbling in the suction chamber is expected if suction is applied.
, Question 8: A patient is prescribed warfarin for atrial fibrillation. Which laboratory test is
used to monitor the therapeutic effect of this medication?
A. Activated partial thromboplastin time (aPTT)
B. International normalized ratio (INR)
C. Platelet count
D. Bleeding time
CORRECT ANSWER: B. International normalized ratio (INR)
Rationale: Warfarin is a vitamin K antagonist that affects the extrinsic pathway of coagulation.
The INR is the standardized test used to monitor warfarin therapy, with a therapeutic target
typically ranging from 2.0 to 3.0 for atrial fibrillation. aPTT is used for heparin monitoring.
Question 9: A nurse is performing a neurological assessment on a patient with a head injury.
The patient opens eyes to pain, makes incomprehensible sounds, and withdraws from pain.
What is the patient's Glasgow Coma Scale (GCS) score?
A. 7
B. 9
C. 11
D. 13
CORRECT ANSWER: B. 9
Rationale: Eye opening to pain = 2, Verbal response (incomprehensible sounds) = 2, Motor
response (withdraws to pain) = 4. Total GCS = 2+2+4 = 8. However, GCS scoring ranges: Eye (1-
4), Verbal (1-5), Motor (1-6). Eye=2, Verbal=2, Motor=4, sum=8. A score of 8 indicates a severe
brain injury.
Question 10: A patient with chronic renal failure is scheduled for hemodialysis. Which of the
following medications should be withheld on the day of dialysis to prevent complications?
A. Digoxin
B. Epoetin alfa
C. Calcium acetate
D. Lisinopril
CORRECT ANSWER: D. Lisinopril
Rationale: Angiotensin-converting enzyme (ACE) inhibitors like lisinopril are often held before
hemodialysis to prevent severe hypotension during the procedure due to rapid fluid shifts and
