QUESTIONS WITH CORRECT ANSWERS

1. A patient with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 L/min
via nasal cannula. The nurse notes the patient’s SpO2 is 89% and the patient appears slightly
short of breath. Which action should the nurse take first?
A. Increase the oxygen flow rate to 4 L/min.
B. Place the patient in a high-Fowler’s position.
C. Notify the healthcare provider immediately.
D. Assess the patient’s respiratory rate and effort.
Answer: D
Conceptual Explanation: The first step in the nursing process is assessment. The nurse
should evaluate the patient’s respiratory status before intervening or notifying the
provider, especially since an SpO2 of 88-92% is often acceptable for COPD patients.
2. A patient with a history of atrial fibrillation is prescribed warfarin. Which laboratory result
indicates that the medication is within the therapeutic range?
A. PTT of 65 seconds
B. INR of 2.5
,C. Platelet count of 150,000/mm3
D. Hemoglobin of 14 g/dL
Answer: B
Conceptual Explanation: For a patient on warfarin for atrial fibrillation, the therapeutic
INR range is typically 2.0 to 3.0. PTT is used to monitor heparin.
3. Which clinical manifestation should the nurse expect to find in a patient experiencing an
Addisonian crisis?
A. Hypotension and hyperkalemia
B. Hypertension and hypernatremia
C. Hyperglycemia and tachycardia
D. Bradycardia and hypokalemia
Answer: A
Conceptual Explanation: Addisonian crisis is characterized by severe hypotension (due to
lack of cortisol and aldosterone), hyponatremia, and hyperkalemia.
4. A patient is admitted with a diagnosis of acute pancreatitis. Which laboratory result is most
specific for this condition?
A. Elevated serum bilirubin
B. Elevated serum lipase
C. Elevated serum amylase
, D. Decreased white blood cell count
Answer: B
Conceptual Explanation: While both amylase and lipase rise in pancreatitis, lipase is more
specific to the pancreas and stays elevated longer than amylase.
5. The nurse is caring for a patient following a thyroidectomy. Which assessment finding
requires immediate intervention?
A. Sore throat when swallowing
B. Laryngeal stridor
C. Pain at the incision site
D. Hoarseness of the voice
Answer: B
Conceptual Explanation: Laryngeal stridor indicates airway obstruction, possibly due to
edema or tetany from hypocalcemia, and is a medical emergency.
6. A patient with type 1 diabetes mellitus is found unconscious with a blood glucose level of
45 mg/dL. Which medication should the nurse prepare to administer?
A. Glucagon IM
B. Regular insulin IV
C. 10 units of NPH insulin
D. Oral glucose gel
