Question 1 of 5
A patient with hypothyroidism states that she takes Synthroid® 0.112 mg daily, but the pharmacy has issued the drug labeled in micrograms. How many micrograms of Synthroid® is equivalent to 0.112 mg? Record your answer using a whole number.
Correct Answer: 112
Rationale:
To convert milligrams to micrograms, multiply by 1,000: 0.112 mg X 1,000 = 112 micrograms.
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
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 4 of 5
The nurse is preparing to administer a dose of hydralazine (Apresoline) to a client with hypertension. The client’s blood pressure is 90/60 mmHg. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: hydralazine is a vasodilator, and a blood pressure of 90/60 mmHg indicates hypotension, so the dose should be withheld
Question 5 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.
