Questions: A nurse is teaching a client about diuretic therapy. Which of the following should the nurse include in the teaching? Creatinine testing measures electrolyte imbalance and renal capacity when the drug is active. Cyanocobalamin testing measures blood and volume status, and final capacity when the drug is active. Cystometric testing measures urine speed and volume, and final capacity when the drug is active. Cystometric testing measures bladder capacity, pressure, and final capacity when the urge to urinate begins.

The answer is the fourth one: Cystometric testing measures bladder capacity, pressure, and final capacity when the urge to urinate begins.

Explanation for each option:

  1. Creatinine testing measures electrolyte imbalance and renal capacity when the drug is active.

    • Incorrect. Creatinine testing is primarily used to assess kidney function and not directly related to measuring electrolyte imbalance or renal capacity in the context of diuretic therapy.

  2. Cyanocobalamin testing measures blood and volume status, and final capacity when the drug is active.

    • Incorrect. Cyanocobalamin is a form of vitamin B12, and testing for it is related to vitamin B12 levels, not blood and volume status or diuretic therapy.

  3. Cystometric testing measures urine speed and volume, and final capacity when the drug is active.

    • Incorrect. Cystometric testing is not used to measure urine speed and volume in the context of diuretic therapy.

  4. Cystometric testing measures bladder capacity, pressure, and final capacity when the urge to urinate begins.

    • Correct. Cystometric testing is a diagnostic procedure that evaluates bladder function by measuring bladder capacity, pressure, and the point at which the urge to urinate begins.

In summary, the correct teaching point for diuretic therapy related to the options provided is about cystometric testing, which measures bladder capacity, pressure, and the urge to urinate.

Exercice ° 1 Données: Célérité de propagation de la lumière dans le vide : C=3.10^8 m · s^-1; On réalise l'expérience de la diffraction de la lumière à d'une source laser monochromatique de longueur d'onde dans le vide λ. On fixe à quelques centimètres de cette source un fil fin de diamètre a une distance D=5,54 m un écran E. 1-On éclaire le fil par la source laser, on observe sur l'écran des taches de diffraction. On désignera la largeur de la tache centrale par L. 1-1) Quelles est la nature de la lumière mise en évidence par le phénomène de diffraction? 1-2) Exprimer la longueur d'onde λ, en fonction de D, L et a, sachant que l'expression de l'écart angulaire entre le milieu de la tache centrale et l'un de ses extrémités est : θ=λ/a. (On considère θ petit) 1-3) On mesure la longueur L de la frange centrale pour différents fils fins. Les résultats obtenus permettent de tracer la courbe de la figure 2, qui représente les variations de L en fonction de 1/a. Par exploitation de cette courbe, déterminer la longueur d'onde λ. 2 - On refait la même expérience en fixant un cheveu exactement à la place du fil. La mesure de la largeur de la tache centrale donne : L′=42 mm Déterminer à l'aide de la courbe, le diamètre d du cheveu.
