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.

Answer and Explanation

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 ["1.8"]

Explanation

Steps to solve:

Convert the client's weight from pounds to kilograms:
- Weight (kg) = Weight (pounds) / 2.20462
- Weight (kg) = 132 pounds / 2.20462 ≈ 59.87 kg (round to nearest tenth for medication calculation)
Calculate the total dantrolene dosage based on the prescribed dosage per kilogram:

- Dosage (mg) = Weight (kg) x Dosage per kg
- Dosage (mg) = 59.87 kg x 1.5 mg/kg
- Dosage (mg) ≈ 89.8 (round to nearest tenth)

Determine the concentration of dantrolene after reconstitution:

Concentration = 50 mg/mL (given on the vial label)

Calculate the volume of the solution to administer:

- Volume (mL) = Dosage (mg) / Concentration (mg/mL)
- Volume (mL) = 89.8 mg / 50 mg/mL
- Volume (mL) ≈ 1.79 mL (round to one decimal place)= 1.8mL

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C","dropdown-group-3":"D"}

Explanation

Short-term memory loss: While some degree of memory loss can be a normal part of aging, significant short-term memory loss in the context of elder mistreatment can indicate neglect or psychological abuse. It might reflect isolation or a lack of proper mental stimulation and care.
Pressure injuries: These are clear indicators of neglect. Pressure injuries, such as bedsores, occur when a person is not moved or repositioned regularly. They can suggest that the caregiver is not providing adequate care or attention to the client's physical needs.
Malnutrition: This is a strong sign of neglect. Malnutrition, evidenced by loss of subcutaneous fat and low body weight, indicates that the client is not receiving adequate nutrition. This could be due to neglect in providing food or a lack of attention to dietary needs, which is a form of mistreatment.
