A 52-year-old client is scheduled for a small-bowel resection in the morning. In conjunction with other preoperative preparation, the nurse is teaching her diaphragmatic breathing exercises. She will teach the client to:
Answer(s): A
(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 2024 times/min does not allow time for full lung expansion to increase oxygenation. This would most likely lead to O2 depletion and hypoxia.
A client's renal calculi are identified as consisting of calcium phosphate. Which of the following diets would be appropriate?
Answer(s): D
(A) The stones consist of calcium and phosphorus; therefore, these minerals should be avoided. A high-calcium diet is contraindicated. (B) A high-phosphorus diet is contraindicated. (C) A 2-g sodium diet is a cardiac diet. (D) A low-calcium and phosphorus diet will reduce further calculi formation.
A client returned to the unit following a pneumonectomy. As the nurse is assessing her incision, she notices fresh blood on the dressing. The nurse should first:
Answer(s): C
(A) The dressing should not be reinforced without first notifying the physician. The decision may be made by the physician to reinforce the dressing after assessing the amount of bleeding. (B) Blood on the dressing is unusual and should make the nurse aware that something more than continuing to monitor the dressing should be done. (C) The physician should be notified immediately, because if the bleeding persists, the client may have to be taken back to surgery. (D) The time and amount of blood do need to be recorded after the physician is notified.
