1. The physician orders 1 unit (270 mL) of PRBCs to infuse 1.5 hours. A. How many mL will the patient receive per hour? B. The nurse uses a blood tubing labeled 10 gtt/mL. What is the flow rate?

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.

2. State the clinical significance of the following: Procedure Determining pulse rate Listening to the flow of blood through the common carotid arteries (auscultate an artery) Determining blood pressure Pulse pressure Mean arterial pressure ****** ******* Clinical significance

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.

iac Lab Report 9. Page 3 of 3 and SV is 70 mL. a. Calculate ESV: b. Calculate EF: C. Based on the given and calculated values, shade in the portion of each vith that represents the volume of blood present and label the shaded area wiu the volume in mL. (Note: The EDV box is always full.) ESV AS After contraction in cardiac contractile cells, some cytosolic calcium is returned to the ECF by Na/Ca secondary active transport carriers in the sarcolemma. Drugs called cardiac glycosides inhibit the sarcolemma Na/K pump. Based on this information, answer these questions about the effects of cardiac glycosides. 000 10. > Cardiac glycosides (increase or decrease?) the Na concentration gradient between the cardiac contractile cell ICF and the ECF. > The change in the Na gradient (increases or decreases?) the activity of the Na/Ca secondary active transport carriers. > As a result, the level of calcium in the cytosol (increases or decreases?). > In the presence of these drugs, the strength of…

Fill in the information below for the ekg rhythm strip?

157. A 35-year-old man comes to the emergency department because of a 2-hour history of severe headache, sweating, and palpitations that began after he moved a heavy couch. He has a history of dizziness when rising from a supine or sitting position, but he is otherwise healthy. On arrival, his blood pressure is 195/95 mm Hg. Which of thefollowing laboratory abnormalities is most likely in this patient?a. Decreased serum calcitonin concentrationb. Decreased serum glucose concentrationC. Increased serum thyroxine (T4) concentrationd. Increased urine hydroxyindoleacetic acid concentratione. Increase urine metanephrine concentration

1. Briefly describe the purpose of Gamma Knife radiosurgery (you do not need to describe the detailed medical procedure)?   2. What does a Gamma Knife cost if you want to buy one, and how much is the annual maintenance contract?

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 zero
