Extract:
Question 1 of 5
Which class of medications are given to liquefy secretions and make them easier to expel?
Correct Answer: A
Rationale: Mucolytics thin mucus, aiding expectoration. Glucocorticoids reduce inflammation, calcium channel blockers treat hypertension, and bronchodilators open airways, not affecting mucus viscosity.
Question 2 of 5
A nurse is assessing an adolescent who has an exacerbation of Graves' disease. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: Heat intolerance occurs in Graves' hyperthyroidism from excess metabolism. Bradycardia , weight gain , and lethargy are hypothyroid symptoms.
Question 3 of 5
Your labs are potassium 6.4, sodium 138, and serum calcium level of 9. Which order from the healthcare provider would the nurse anticipate?
Correct Answer: C
Rationale: Kayexalate binds potassium in the gut, facilitating its excretion, effectively lowering serum levels (6.4 mEq/L) in hyperkalemia. Fluid restriction may worsen potassium concentration, neomycin is irrelevant, and sodium chloride with furosemide is less direct than Kayexalate for rapid correction.
Question 4 of 5
The nurse is providing education to a client who is newly diagnosed with lupus. Which of the following statements would require further teaching?
Correct Answer: A
Rationale: Sun exposure triggers lupus rashes, so it increases, not decreases, risk. Ibuprofen , fever as a flare sign , and rest are correct.
Question 5 of 5
Which of the following medications are going to dilate the coronary arteries and redirect blood flow so that ischemic tissue is oxygenated?
Correct Answer: D
Rationale: Nitroglycerin dilates coronary arteries, increasing blood flow to ischemic myocardium. Salmeterol is a bronchodilator, aspirin prevents clotting, and digoxin enhances contractility, none dilating coronary vessels.
