A patient with a history of PUD and a positive H. pylori test is prescribed a combination of antibiotics and a proton pump inhibitor. The patient asks why so many medications are needed. The nurse should explain:

Correct Answer: B

Rationale: The regimen reduces acid (PPI) and eradicates H. pylori (antibiotics) synergistically.

Correct Answer: A

Rationale: Bromocriptine's usefulness is severely limited by nausea and vomiting, and this is a problem even in therapeutic doses. Benzhexol and other atropinics may cause dry mouth, gastrooesophageal reflux and constipation. However, the most serious adverse effects for these drugs are neuropsychiatric.

Correct Answer: C

Rationale: Proteins and starches are too large to diffuse into cells. Proteins are digested into amino acids , and starches into simple sugars , matching digestion products.

Correct Answer: D

Rationale: Choices A, B, and C are correct: the tongue manipulates food, saliva (with amylase) converts starches to sugars, and it positions food for chewing. D is incorrect because chewing enhances digestion by breaking food into smaller pieces, but 'digestive juices reacting more easily' is vague and not a primary mouth function—digestion continues later with gastric and intestinal juices.

Correct Answer: B

Rationale: The liver stores glycogen , produces bile , and can regenerate , but insulin is made by the pancreas, not the liver, making B correct.
