Take a large gulp of air into the mouth, hold it for 10-15 seconds, and then expel it through the nose. Repeat 4 -5 times to complete the series D. Inhale as deeply as possible and then immediately exhale as deeply as possible at a rate of approximately 20-24 times/min Answer: A Explanation: (A) This is the correct method of teaching diaphragmatic breathing, which allows full lung expansion to increase oxygenation, prevent atelectasis, and move secretions up and out of the lungs to decrease risk of pneumonia. (B) Quick, short breaths do not allow for full lung expansion and movement of secretions up and out of the lungs. Quick, short breaths may lead to O2 depletion, hyperventilation, and hypoxia. (C) Expelling breaths through the nose does not allow for full lung expansion and the use of diaphragmatic muscles to assist in moving secret ions up and out of the lungs. (D) Inhaling and exhaling at a rate of 20 -24 times/min does not allow time for full lung expansion to increase oxygenation. This would most likely lead to O2 depletion and hypoxia.

Apply ice packs to both legs. B. Begin debridement by removing all charred clothing from wound. C. Apply Silvadene cream (silver sulfadiazine). D. Immerse both legs in cool water. Answer: D Explanation: 14 (A) Ice creates a dramatic temperature change in the tissue, which can cause further thermal injury. (B) Charred clothing should not be removed from wound first. This creates further tissue damage. Debridement is not the first nursing action. (C) Applying silver sulfadiazine cream first insulates heat in injured tissue and increase s potential for infection. (D) Emergency care of a thermal burn is immersing both legs in cool water. Cool water permits gradual temperature change and prevents further thermal damage. NO.34 The nurse notes scattered crackles in both lungs and 1+ pitting edema when assessing a cardiac client. The physician is notified and orders furosemide (Lasix) 80 mg IV push stat. Which of the following diagnostic studies is monitored to assess for a major complication of this therapy? A. Serum electrolytes B. Arterial blood gases C. Complete blood count D. 12-Lead ECG Answer: A Explanation: (A) Furosemide, a potassium -depleting diuretic, inhibits the reabsorption of sodium and chloride from the loop of Henle and the distal renal tubules. Serum electrolytes are monitored for hypokalemia. (B) Severe acid-base imbalances influence the movement of potassium into and out of the cells, but arterial blood gases to not measure the serum potassium level. (C) Furosemide is a potassium -depleting diuretic. A complete blood count does not reflect potassium levels.
