The nurse is preparing to administer a histamine 2-receptor antagonist to a client with peptic ulcer disease. What is the primary purpose of this drug classification?
Neutralizes hydrochloric acid (HCI) in the stomach.
Inhibits action of acetylcholine by blocking parasympathetic nerve endings.
Destroys microorganisms causing stomach inflammation.
Decreases the amount of HCI secretion by the parietal cells in the stomach.
The Correct Answer is D
A. Histamine 2-receptor antagonists do not directly neutralize hydrochloric acid (HCl) in the stomach. Instead, they reduce acid secretion by blocking the histamine 2 receptors on parietal cells, thereby decreasing the production of gastric acid.
B. This describes the mechanism of action of anticholinergic medications, not histamine 2- receptor antagonists.
C. Histamine 2-receptor antagonists do not have antimicrobial properties and are not used to destroy microorganisms causing stomach inflammation. They primarily target acid secretion.
D. This is the correct purpose of histamine 2-receptor antagonists. They work by blocking the action of histamine on parietal cells in the stomach, leading to a reduction in the secretion of hydrochloric acid. This helps in the management of peptic ulcer disease and other conditions related to excessive gastric acid secretion.

Correct Answer is B
Explanation
A. Instruct the family about withdrawal symptoms. While educating the family about withdrawal symptoms is important for support and understanding, it is not the best initial action when the
client is experiencing severe agitation and tremors. Safety measures should be prioritized.
B. Initiate seizure precautions. Severe agitation and tremors can be signs of benzodiazepine withdrawal, which may progress to seizures. Initiating seizure precautions, such as ensuring a
safe environment, padding side rails, and having emergency medications and equipment readily available, is the priority to prevent injury.
C. Obtain a serum drug screen. While obtaining a serum drug screen may be necessary to confirm benzodiazepine withdrawal, it is not the immediate action needed to address the client's current symptoms and prevent potential harm.
D. Administer naloxone per PRN protocol. Naloxone is an opioid antagonist used to reverse opioid overdose and is not indicated for benzodiazepine withdrawal. Administering naloxone would not be appropriate or effective in this situation.
Correct Answer is ["0.8"]
Explanation
- Convert the client's weight from pounds to kilograms (kg).
- Calculate the enoxaparin sodium dosage per day based on the client's weight and the prescribed dosage of 1.5 mg/kg/day.
- Divide the enoxaparin sodium dosage by the concentration of the medication in the prefilled syringe (120 mg/0.8 mL) to determine the volume to administer.
Step 1: Convert weight from pounds to kilograms
-
- Client's weight in kg = Client's weight in pounds / 2.2
-
- Client's weight in kg = 176 pounds / 2.2 = 80 kg
Step 2: Calculate enoxaparin sodium dosage per day
-
- Enoxaparin sodium dosage (mg/day) = Client's weight (kg) × Prescribed dosage (mg/kg/day)
- Enoxaparin sodium dosage (mg/day) = 80 kg × 1.5 mg/kg/day = 120 mg/day
Step 3: Determine the volume to administer
-
- Volume to administer (mL) = Enoxaparin sodium dosage (mg/day) / Medication concentration (mg/mL)
- Volume to administer (mL) = 120 mg/day / (120 mg/0.8 mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of enoxaparin sodium to the client.
