Ultrasound Questions and Answers 2023 What is ultrasound? Ultrasound is any sound wave above the frequency of 20kHz (above human hearing). What type of waves are sound waves, and what does this mean for them? Sound waves are longitudinal waves - so they can only pass through a material medium, not a vacuum. How can we figure out the wavelength of ultrasound waves in tissue? λ = v/f What does the equation λ = v/f show? The higher the frequency, the shorter the waveleng...

  NCLEX RN ACTUAL EXAM TEST BANK OF REAL QUESTIONS & ANSWERS NCLEX 2022 QUESTION 1 Which classification of drugs is contraindicated for the client with hypertrophic cardiomyopathy? A. Positive inotropes B. Vasodilators C. Diuretics D. Antidysrhythmics Answer: A Explanation: (A) Positive inotropic agents should not be administered owing to their action of increasing myocardial contractility. Increased ventricular contractility would increase outflow tract obstr...

Parents ask the nurse, When should our childs hypospadias be corrected? The nurse responds based upon the knowledge that correction of hypospadias should be accomplished by the time the child is: a. 1 month of age. b. 6 to 8 months of age. c. school age. d. sexually mature. ANS: B The correction of hypospadias should ideally be accomplished by the time the child is 6 to 8 months of age and before toilet training. Surgery to correct hypospadias is not performed when the infant is less th...
