A nurse is caring for a patient with decreased triiodothyronine (T3) and thyroxine (T4) and elevated thyroid-stimulating hormone (TSH) levels. The nurse knows the patient is likely suffering from what?
Hyperthyroidism
Hypothyroidism
Thyroid cancer
Pituitary adenoma
The Correct Answer is B
Choice A reason: Hyperthyroidism involves elevated T3 and T4 with low TSH due to excessive thyroid hormone production. The patient’s low T3/T4 and high TSH indicate reduced thyroid activity, not overactivity, as the pituitary increases TSH to stimulate the underactive thyroid, making this choice incorrect.
Choice B reason: Hypothyroidism is characterized by low T3 and T4 levels due to underactive thyroid function, prompting the pituitary to secrete more TSH to stimulate hormone production. This matches the patient’s lab results (low T3/T4, high TSH), often seen in primary hypothyroidism, making this the correct choice.
Choice C reason: Thyroid cancer may alter thyroid function but typically doesn’t present with consistently low T3/T4 and high TSH. It’s more likely to cause nodules or abnormal growths, not this specific hormonal pattern, which aligns with hypothyroidism, making this choice less likely.
Choice D reason: Pituitary adenoma causing secondary hypothyroidism would lower TSH, T3, and T4 due to impaired pituitary function. High TSH with low T3/T4 suggests primary thyroid failure, not pituitary dysfunction, making this choice incorrect for the patient’s hormonal profile.

Correct Answer is B
Explanation
Choice A reason: Glargine provides basal, not insulin, coverage; meal coverage. It maintains steady glucose control, so this is incorrect.
Choice B reason: Insulin glargine offers 24-hour basal glucose control, stabilizing blood sugar without peaks. This is its primary effect, making it the correct outcome.
Choice C reason: Glargine requires regular monitoring, not less frequent monitoring, to ensure control. This is incorrect for the therapeutic outcome.
Choice D reason: Glargine has no peak, unlike short-acting insulins, with effects lasting 24 hours. A 2–4 hour peak is incorrect, so incorrect.
Correct Answer is ["B","D","E"]
Explanation
Choice A reason: NSAIDs, like ibuprofen, exacerbate peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD) by inhibiting COX-1, reducing protective gastric mucus and increasing acid-related damage. They are contraindicated in these conditions, making this choice incorrect for treatment.
Choice B reason: Antacids neutralize gastric acid, providing rapid symptom relief in PUD and GERD by reducing acid irritation on the esophagus and stomach lining. They are a standard, non-prescription option for mild symptoms, making this a correct choice for managing these conditions.
Choice C reason: Laxatives treat constipation by promoting bowel movements but have no role in PUD or GERD, which involve acid-related damage to the stomach or esophagus. They don’t affect gastric acid or mucosal protection, making this choice incorrect for treatment.
Choice D reason: H2 antagonists, like ranitidine, reduce gastric acid secretion by blocking histamine receptors on parietal cells, promoting ulcer healing and relieving GERD symptoms. They are a mainstay treatment for both conditions, making this a correct choice for effective management.
Choice E reason: Proton pump inhibitors, like omeprazole, strongly inhibit gastric acid production by blocking the proton pump in parietal cells, allowing ulcer healing and reducing GERD symptoms. They are first-line therapy for PUD and GERD, making this a correct choice.
