An adult patient visits the clinic expressing concern about a lump that appeared on their neck about a week ago.
Upon examination, the nurse finds a large, non-tender, hardened left subclavian lymph node without any overlying tissue inflammation.
What could these findings indicate?
Malignancy
Bacterial infection
Viral infection
Lymphangitis .
The Correct Answer is A
Choice A rationale
A large, non-tender, hardened lymph node without overlying tissue inflammation could indicate malignancy. Lymph nodes may become enlarged or hard due to the presence of cancer cells.
Choice B rationale
While bacterial infections can cause lymph node enlargement, they typically also cause tenderness and overlying skin changes, such as redness or warmth.
Choice C rationale
Viral infections can cause generalized lymph node enlargement, but the nodes are usually tender and not hard.
Choice D rationale
Lymphangitis, or inflammation of the lymphatic channels, typically presents with red streaks on the skin, fever, and tenderness.

Correct Answer is B
Explanation
Choice A rationale
A blood glucose level of 90 mg/dL (5 mmol/L) is within the normal range and would not need to be reported to the surgeon.
Choice B rationale
A serum creatinine level of 5 mg/dL (442 µmol/L) is significantly elevated, indicating impaired kidney function. This is a critical lab value that should be reported to the surgeon immediately, as it could impact the patient’s ability to safely undergo surgery and recover postoperatively.
Choice C rationale
A hemoglobin level of 13 g/dL (130 g/L) is within the normal range and would not need to be reported to the surgeon.
Choice D rationale
A potassium level of 4 mEq/L (4 mmol/L) is within the normal range and would not need to be reported to the surgeon.
Correct Answer is A
Explanation
Choice A rationale
Histamine H2-receptor antagonists, also known as H2 blockers, are medications that help reduce the production of gastric acid. They achieve this by blocking H2 receptors in the parietal cells of the stomach, which are responsible for secreting hydrochloric acid (HCl)12. This reduction in acid secretion can help treat conditions such as peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome, which are all conditions that can be exacerbated by excessive stomach acid.
Choice B rationale
While H2 blockers do help manage the symptoms of peptic ulcer disease, they do not directly destroy the microorganisms causing inflammation in the stomach. The primary cause of peptic ulcers is a bacterium called Helicobacter pylori, and the treatment for an H. pylori infection typically involves a combination of antibiotics and proton pump inhibitors, not H2 blockers.
Choice C rationale
H2 blockers do not neutralize hydrochloric acid (HCl) in the stomach. Instead, they work by reducing the amount of acid produced by the stomach. Antacids, not H2 blockers, are the class of drugs that work by neutralizing stomach acid.
Choice D rationale
H2 blockers do not inhibit the action of acetylcholine by blocking parasympathetic nerve endings. Anticholinergic medications are the ones that work by blocking the action of acetylcholine, a neurotransmitter that transmits signals in the nervous system.
