(C) The lab results indicate that the client's lithium level is within therapeutic range (0.2-1.4 mEq/L), so the medication should be given as ordered. (D) Benztropine is an antiparkinsonism drug frequently given to counteractextrapyramidal symptoms associated with the administration of antipsychotic drugs (not lithium). NO.29 The primary focus of nursing interventions for the child experiencing sickle cell crisis is aimed toward: A. Maintaining an adequate level of hydration B. Providing pain relief C. Preventing infection D. O2 therapy Answer: A Explanation: (A) Maintaining the hydration level is the focus for nursing intervention because dehydration enhances the sickling process. Both oral and parenteral fluids are used. (B) The pain is a result of the sickling process. Analgesics or narcotics will be used for symptom relief, but the underlying cause of the pain will be resolved with hydration. (C) Serious bacterial infections may result owing to splenic dysfunction. This is true at all times, not just during the acute period of a crisis. (D) O2 therapy is used for symptomatic relief of the hypoxia resulting from the sickling process. Hydration is the primary intervention to alleviate the dehydration that enhances the sickling process. NO.30 Three weeks following discharge, a male client is readmitted to the psychiatric unit for depression. His wife stated that he had threatened to kill himself with a handgun. As the nurse admits him to the unit, he says, "I wish I were dead because I am worthless to everyone; I guess I am just no good." Which response by the nurse is most appropriate at this time? A.

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 secretions 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. NO.32 The nurse enters the playroom and finds an 8-year-old child having a grand mal seizure. Which one of the following actions should the nurse take? A. Place a tongue blade in the child's mouth.

(D) The nurse should provide safety for the child by moving objects and protecting the head. NO.33 An 11-year-old boy has received a partial-thickness burn to both legs. He presents to the emergency room approximately 15 minutes after the accident in excruciating pain with charred clothing to both legs. What is the first nursing action? A. 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: IT Certification Guaranteed, The Easy Way! 13(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 increases 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. (D) Abnormalities in potassium (both hyperkalemia and hypokalemia) are reflected in ECG changes, but these changes do not occur until the abnormality is severe. [Show More]
