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 C

Explanation

A. Left 5th intercostal space midclavicular line: Palpating the left 5th intercostal space midclavicular line is not appropriate for assessing pulse in an unresponsive infant. This location is typically used for cardiac auscultation and not for pulse assessment.
B. Right carotid area: Palpating the carotid artery is not recommended in infants due to the risk of causing injury to the delicate structures of the neck, including the
airway and blood vessels.

C. Over the brachial artery: The brachial artery is the preferred site for assessing pulse in infants. It is located in the inner aspect of the upper arm and can be easily palpated. In an unresponsive infant, the brachial pulse should be assessed before
initiating CPR.

D. Over the sternum: Palpating over the sternum is not an appropriate site for pulse assessment in infants. The sternum is a bone and does not contain any major arteries suitable for pulse palpation.

A. Provide a list of alternative activities that are less likely to cause the child to experience fatigue. B. Suggest that the child be encouraged to participate in a team sport to encourage socialization. C. Explain that their child is too young to understand the risks associated with swimming. D. Encourage the parents to allow the child to continue attending swimming lessons with supervision.

Correct Answer is D

Explanation

- A: Providing a list of alternative activities may reduce fatigue, but it does not consider the child's interest in swimming, which can be therapeutic and enjoyable for children with Duchenne muscular dystrophy.
- B: While team sports can be good for socialization, they may not be suitable for a child with Duchenne muscular dystrophy due to the progressive muscle weakness associated with the condition, which could lead to increased risk of injury.
- C: At the age of 6, children are capable of understanding basic risks, and it is important to communicate with them appropriately rather than assuming they are too young. Moreover, swimming can be adapted to be safe for children with physical limitations.
- D: Swimming is an excellent activity for children with Duchenne muscular dystrophy because it is low-impact and can help maintain muscle strength and function. With proper supervision and precautions, the risks can be managed, making it a suitable activity for the child to continue.
