A patient, newly diagnosed with a peptic ulcer, needs more education when he states:

A. Antacids: Antacids are generally used to neutralize stomach acid and can provide symptomatic relief for peptic ulcer disease (PUD). They are not typically contraindicated and can be part of the treatment regimen, although they do not address the underlying cause of PUD.
B. NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to irritate the gastric mucosa and can exacerbate or cause peptic ulcers by inhibiting the production of protective prostaglandins in the stomach lining. Patients with peptic ulcer disease should avoid NSAIDs to prevent further irritation and ulcer formation.
C. PPIs: Proton pump inhibitors (PPIs) are commonly prescribed to reduce gastric acid secretion and promote ulcer healing in peptic ulcer disease. They are a key component of the treatment regimen and not to be avoided unless there are specific contraindications.
D. H2-receptor blockers: H2-receptor blockers reduce stomach acid production and are used to treat and prevent peptic ulcers. They are an important part of the management strategy for PUD and are not typically contraindicated.

A. Repeating instructions: Repeating instructions can reinforce learning but does not guarantee that the patient has correctly understood or can apply the instructions. It does not provide an opportunity for the nurse to observe and correct errors.
B. Assessing lung sounds: Assessing lung sounds helps evaluate the effectiveness of the inhaled medication but does not verify whether the patient is using the inhaler correctly.
C. Return demonstration: A return demonstration involves the patient showing the nurse how they use the inhaler. This allows the nurse to observe the technique and provide immediate feedback and correction, ensuring proper use.
D. Answering questions: Answering questions can clarify doubts and enhance understanding, but it does not confirm that the patient is correctly using the inhaler.
