HESI Exit Exam 2021.

HESI Exit Exam 2021. Rationale: These ABGs reveal respiratory alkalosis, and treatment depends on the underlying cause. Because the client is only 6 hours postoperative, he or she should be assessed for pain because treating the pain will correct the underlying problem. A PaO2 of 96 mm Hg does not indicate the need for an increase in oxygen administration. The PaCO2 indicates mild hyperventilation, so option C is not indicated. In addition, it is very difficult to change one's breathing pattern. The use of sodium bicarbonate is indicated for the treatment of metabolic acidosis, not respiratory alkalosis. 4. A 77-year-old female client states that she has never been so large around the waist and that she has frequent periods of constipation. Colon disease has been ruled out with a flexible sigmoidoscopy. Which information should the nurse provide to this client? A. As women age, they often become rounder in the middle because they do not exercise properly. B. Further assessment is indicated because loss of abdominal muscle tone and constipation do not occur with aging. C. With age, more fatty tissue develops in the abdomen and decreased intestinal movement can cause constipation. D. Because there is no evidence of a diseased colon, there is no need to worry about abdominal size. Rationale: With aging, the abdominal muscles weaken as fatty tissue is deposited around the trunk and waist. Slowing peristalsis also affects the emptying of the colon, resulting in constipation. Option A is not the primary reason for the changes in body structure. Option B is not indicated because loss of muscle tone and constipation are age-related changes. Option D dismisses the client's concerns and does not help her understand the changes that she is experiencing. 5. A mother of a 12-year-old boy states that her son is short and she fears that he will always be shorter than his peers. She tells the nurse that her grown daughter only grew 2 inches after she was 12 years of age. To provide health teaching, which question is most important for the nurse to ask this mother? A. "Is your son's short stature a social embarrassment to him or the family?" B. "What types of foods do both your children eat now and what did they eat when they were infants?" C. "Did any significant trauma occur with the birth of your son?" D. "Did your daughter also start her menstrual period at 12 years of age?"
