9.The client is on a ventilator on assist control (AC) with a respiratory rate of 18 breaths per minute, Tidal volume is set at 600 mL with an F102 of 40%. Arterial blood gases are pl of 7.5, PO2 of 94mmHg, PCO) of 28mmHg. HCO3 of 24mEq/L. and 96% oxygen saturation. Which of the following actions would most likely improve the client's blood gases? Decrease the client's set respiratory rate. Increase the client's F102. Change the client to IMV mode. Increase the client's tidal volume, A Decrease the client's set respiratory rate B.Increase the client's F102 C.Change the client to IMV mode D.Increase the client's tidal volume15. While reviewing the medications ordered for a client with acute renal failure who has been admitted to the ICU, the nurse notes an order for Mannitol, which is used to; a.replace interstitial fluid volume. b.increase cardiac output c enhance the effectiveness of ultrafiltration during dialysis d, block sodium reabsorption in the loop of Heale.16.A client is to be dialyzed within the next three hours. The client has an order for 20mg of propranolol (Inderal) in two hours. In order to prevent hypotension during dialysis, the nurse should: a administer the medication at the regularly scheduled time b administer the medication now so that it wears off before dialysis. c.hold the dose. d.administer 500mL of normal saline immediately prior to dialysis.20.The nurse is aware that oxygen toxicity on mechanically ventilated clients can be prevented by: Alusing positive end-expiratory pressure (PEEP) B administering a high tidal volume. C.keeping the client's PaO_ below 80mmHg Dusing intennittent mechanical ventilation (INV ) instead of assist control ( AC ) mode
