5. How do you assure a high flow t-piece is really meeting the patient's needs?
Step by step
Solved in 3 steps
- 6.How is blood flow to the various regions of the body controlled?3. An IV with 800 ml remaining is running at 25 gtt/min on a 15 gtt/ml calibrated set. What is the infusion time? (Round to the nearest whole number in hours).10. The nurse is taking the client's blood pressure. The physician asks for the pulse pressure. To obtain the pulse pressure, the nurse will have to do which of the following things? A. Obtain a pulse-pressure machine. B. Subtract the diastolic blood pressure from the systolic. C. Subtract the systolic blood pressure from the diastolic. D. Take client's apical pulse and subtract it from systolic.
- 40. If all the pre-capillary sphincters should be open at the same time, the blood pressure will drop. True False16. What types of things will cause arterioles to constrict, and what does this do to the associated capillary bed? How about the opposite? (what makes arterioles dilate, what happens to the capillary bed).6. What is the purpose of the coronary artery? What results if there is blockage in this vessel?
- 7. The client continues to have uterine con- tractions, and a new order has been writ- ten: magnesium sulfate 4 g IV bolus over 20 minutes, then 1 g/h. The label on the IV bag states "magne- sium sulfate 40 g in 1,000 mL." - What is the rate of flow in mL/h for the bolus dose? - What is the rate of flow in mL/h for the maintenance dose? The client continues to have contractions and her membranes rupture. The follow- ing orders are written: - Discontinue the magnesium sulfate. · Pitocin (oxytocin) 10 units/1,000 mL RL, start at 0.5 mU/min increase by 1 mU/min q20 minutes. · Stadol (butorphanol tartrate) 1 mg IVP stat.2.2. How is an action potential in a contractile cardiac cell different from action potential in a pacemaker cell? (Write the phases and the channels involved for each phase).
- 9. You are preparing to administer lactated Ringer's 3,000 mL IV to infuse over 20 hr. The drop factor of the manual IV tubing is 30 gtt/mL. The nurse should adjust the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero4. The ECG records the electrical stimulation of cardiac muscle by the conduction system and not the contraction of the muscle itself.? True or False ?11. Explain the principles underlying the measurement of blood pressure using a sphygmomanometer
