Question 1 of 5
The nurse is caring for a client with a medical prescription for clozapine [Clozaril]. The nurse knows which of the following is the priority laboratory value that should be reviewed prior to medication administration?
Correct Answer: A
Rationale: Clozapine risks agranulocytosis; monitoring WBC count is critical before administration. Other labs are less urgent.
Question 2 of 5
Which of the following will the nurse include in teaching for a client taking ferrous sulfate [Feosol]?
Correct Answer: A
Rationale: Diluting liquid ferrous sulfate and using a straw prevents tooth staining and aids absorption. Dairy inhibits absorption, green/black stools are normal, and citrus juices enhance absorption.
Question 3 of 5
The nurse is evaluating the therapeutic effects of nitroglycerin transdermal patches prescribed to a client 6 months ago. Which of the following statements by the client would indicate that the medication is effective?
Correct Answer: C
Rationale:
Tolerating exercise without pain indicates nitroglycerin effectively prevents angina, its primary goal. BP improvement, no attacks, and fewer headaches are less specific indicators.
Question 4 of 5
A client is brought to the emergency department in acute alcohol withdrawal. Which of the following medications does the nurse anticipate will be ordered to prevent seizures and delirium tremens?
Correct Answer: C
Rationale: Diazepam, a benzodiazepine, prevents seizures and delirium tremens in alcohol withdrawal. Zolpidem, morphine, and fluoxetine are inappropriate.
Question 5 of 5
A client is taking a calcium channel blocker (CCB). The nurse knows to monitor for which of the following dangerous side effects of this medication?
Correct Answer: A
Rationale: CCBs can worsen heart failure by reducing cardiac contractility, a dangerous side effect. Drowsiness and headache are less severe, and hypertension is treated by CCBs.
