Extract:
Question 1 of 5
The nurse caring for a client with a suspected peptic ulcer recognizes which exam as the one most reliable in diagnosing the disease?
Correct Answer: C
Rationale: Endoscopy directly visualizes the gastric mucosa, allowing for biopsy and definitive diagnosis of a peptic ulcer, making it the most reliable method.
Question 2 of 5
The nurse is caring for a client with a head injury who has increased ICP. The physician plans to reduce the cerebral edema by constricting cerebral blood vessels. Which physician order would serve this purpose?
Correct Answer: A
Rationale: Hyperventilation reduces PaCO2, causing cerebral vasoconstriction, which decreases cerebral blood flow and edema. The other options address pressure or fluid but not vasoconstriction.
Question 3 of 5
A client with a head injury develops syndrome of inappropriate antidiuretic hormone (SIADH). Which physician prescription would the nurse question?
Correct Answer: A
Rationale: D5W at 200 mL/hr is inappropriate for SIADH, as it can worsen hyponatremia by adding free water. The other options are appropriate for monitoring and treating SIADH.
Question 4 of 5
The nurse is conducting a physical assessment on a client with anemia. Which of the following clinical manifestations would be most indicative of the anemia?
Correct Answer: B
Rationale: Tachypnea (respirations 28 shallow) is a common sign of anemia due to reduced oxygen-carrying capacity, prompting compensatory increased respiratory rate.
Question 5 of 5
The nurse recognizes all of the following as part of the Cushing reflex triad EXCEPT
Correct Answer: A
Rationale: Cushing reflex (response to increased intracranial pressure) includes hypertension, bradycardia, and irregular respirations. Cardiac arrhythmia is not part of the triad.
