Question 1 of 9
What is levothyroxine's pharmacologic classification?
Correct Answer: A
Rationale: Levothyroxine belongs to the pharmacologic classification of thyroid preparations. It is a synthetic form of the thyroid hormone thyroxine (T4) and is used to treat hypothyroidism by supplementing or replacing the body's own thyroid hormone. Levothyroxine works to normalize thyroid hormone levels in the body and help regulate metabolism. It is not a metabolic inhibitor, analgesic, or loop diuretic.
Question 2 of 9
The nurse is reviewing the care plan with a patient using enteral nutrition (EN). Which interventions by the nurse are appropriate for this strategy? (Select all that apply.)
Correct Answer: A
Rationale: Checking gastric residuals (A) ensures proper gastric emptying and reduces aspiration risk. Elevating the bed (B) prevents reflux and aspiration. Reporting absent bowel sounds (D) is critical, as EN is contraindicated in ileus. Feeding bags and tubing should be changed every 24 hours, not 3 to 4 days (C).
Question 3 of 9
When assessing a patient who is receiving a loop diuretic, the nurse looks for the manifestations of potassium deficiency, which would include what symptoms? (Select all that apply.)
Correct Answer: D
Rationale: Loop diuretics can cause excessive potassium excretion in the urine, leading to low potassium levels in the body (hypokalemia). Some manifestations of potassium deficiency (hypokalemia) include muscle weakness, which can range from mild to severe, and anorexia (loss of appetite). Other symptoms of hypokalemia may include fatigue, weakness, constipation, and even cardiac arrhythmias. It is important for healthcare providers to monitor patients on loop diuretics for signs of potassium deficiency to prevent complications.

Correct Answer: A
Rationale: Patients with peptic ulcers should stop taking NSAIDs. NSAIDs, which stands for nonsteroidal anti-inflammatory drugs, can worsen peptic ulcers by increasing the risk of gastrointestinal bleeding and ulcer formation. NSAIDs work by inhibiting prostaglandin synthesis, which can lead to a decrease in the protective mucus production in the stomach lining, allowing gastric acid to damage the mucosa and exacerbate peptic ulcers. Therefore, it is crucial for patients with peptic ulcers to avoid NSAIDs to prevent further damage to the gastrointestinal tract.
Question 5 of 9
A 24-year-old beautician has a history of chronic fatigue since an attack of infectious mononucleosis when aged 20. Her fatigue has become progressively worse. Her periods are painful, heavy and irregular. Her BP is 116/62 (supine) and 92/52 (standing). Serum Na+ is 132, K+ 5.5, creatinine 60 μmol/L. Which of the following would be most appropriate management?
Correct Answer: D
Rationale: Fatigue, orthostatic hypotension (116/62 to 92/52), hyponatremia (Na+ 132), and hyperkalemia (K+ 5.5) post-mononucleosis suggest Addison's disease (adrenal insufficiency). Fludrocortisone treats mineralocorticoid deficiency but needs diagnosis first. CBT addresses fatigue psychologically, not endocrine causes. Aciclovir treats viral infections, irrelevant here. Tetracosactide (Synacthen) tests adrenal function, diagnosing Addison's by cortisol response, most appropriate to confirm before lifelong therapy. This diagnostic step ensures accurate management, critical in suspected adrenal failure.
Question 6 of 9
When administering a standard or median effective dose to a patient, the nurse explains that this amount of drug will have which effect?
Correct Answer: C
Rationale: Median effective dose (ED50) affects 50% of a population, a statistical pharmacodynamic measure, not individual guarantee. No adverse effects isn't assured-safety varies. Metabolism timing depends on half-life, not ED50. Majority effectiveness exceeds 50%. Half the population defines ED50, explaining its intent.
Question 7 of 9
The patient tells the nurse, 'I thought I was just depressed, but my doctor says I have bipolar disorder. What is that?' What is the best response by the nurse?
Correct Answer: D
Rationale: Bipolar disorder features mood cycles-depression and mania (hyperactivity)-per DSM-5, distinct from unipolar depression. It's not just cyclic depression, nor ADHD-linked. Seasonal shifts are separate (SAD). Mania-depression cycles define it, clarifying diagnosis.
Question 8 of 9
A patient complains about a burning sensation and pain when urinating. Which urinary analgesic does the nurse suspect will be ordered?
Correct Answer: D
Rationale: Phenazopyridine is a urinary analgesic commonly used to relieve the burning sensation and pain experienced during urination, typically caused by urinary tract infection or irritation. It works by acting as a local anesthetic on the lining of the urinary tract, providing relief from discomfort. Tolterodine and oxybutynin are used to treat overactive bladder by reducing bladder spasms and urge incontinence, whereas bethanechol is a direct-acting cholinergic agonist primarily used to stimulate bladder contractions in individuals with urinary retention. Thus, for the symptom of burning sensation and pain when urinating, phenazopyridine would be the most likely urinary analgesic to be ordered.
Question 9 of 9
A 33-year-old man with a history of chronic epididymoorchitis is treated with long-term tetracycline antibiotic therapy. During the 3 months of therapy, he develops discoloration of his teeth. What is the most likely explanation for this finding?
Correct Answer: A
Rationale: Tetracycline causes tooth discoloration by binding to calcium in developing teeth . Drug toxicity is vague. Folate synthesis , hepatic enzymes , and osteoclasts (E) aren't involved. This chelation stains enamel, a known effect with prolonged use.
