Extract:
Question 1 of 5
What is the first action the nurse should take with the accidental dislodgement of a chest tube?
Correct Answer: C
Rationale: Sealing the chest tube site with a sterile dressing taped on three sides is the immediate priority to prevent pneumothorax by creating a one-way valve.
Question 2 of 5
The physician orders 500 mg PO of medication. The Medication is supplied as a suspension 125 mg/5mL. How many mL will the nurse administer for one dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The dose is 500 mg, and the suspension is 125 mg/5 mL. Proportion: 125 mg / 5 mL = 500 mg / x mL. Solving gives x = 20 mL.
Question 3 of 5
What is the first action the nurse should take with the accidental dislodgement of a chest tube?
Correct Answer: C
Rationale: Applying a sterile dressing taped on three sides prevents air entry into the pleural space, reducing pneumothorax risk until further intervention.
Question 4 of 5
The nurse is caring for a client diagnosed with pneumonia. Which medication will the nurse administer for treatment of client's problem of ineffective airway clearance?
Correct Answer: C
Rationale: Guaifenesin is an expectorant that helps loosen mucus, facilitating productive coughing to clear airways in pneumonia.
Question 5 of 5
The nurse is caring for a client with the following arterial blood gas (ABG) results: pH 7.17, PaCO2 47 mmHg, Pa02 82 mmHg, HCO3 29 mEq/L. The nurse would interpret these results as:
Correct Answer: B
Rationale: Low pH (7.17) and high PaCO2 (47 mmHg) indicate respiratory acidosis, with elevated HCO3 (29 mEq/L) showing partial compensation.
