A nurse is caring for a client who has a history of chronic obstructive pulmonary disease (COPD) and is receiving oxygen therapy at home. The nurse should instruct the client to report which of the following findings as an indication of oxygen toxicity?
Headache
Dry mouth
Increased appetite
Nausea
The Correct Answer is A
Choice A reason: Headache is a sign of oxygen toxicity, which is a condition that occurs when the client receives too much oxygen for a prolonged period of time. Oxygen toxicity can damage the lungs and other organs, and cause symptoms such as confusion, seizures, and respiratory failure. The nurse should instruct the client to report headache and adjust the oxygen flow rate accordingly.
Choice B reason: Dry mouth is not a sign of oxygen toxicity, but it could be a side effect of some medications or a result of dehydration. The nurse should instruct the client to drink plenty of fluids and use a humidifier or a nasal saline spray to moisten the mucous membranes.
Choice C reason: Increased appetite is not a sign of oxygen toxicity, but it could be a positive outcome of oxygen therapy, as it indicates improved oxygenation and metabolism. The nurse should encourage the client to eat a balanced diet and monitor their weight and nutritional status.
Choice D reason: Nausea is not a sign of oxygen toxicity, but it could be a side effect of some medications or a symptom of another condition, such as gastroesophageal reflux disease (GERD) or peptic ulcer disease (PUD). The nurse should instruct the client to take their medications as prescribed and avoid foods that trigger nausea, such as spicy, fatty, or acidic foods.

Correct Answer is C
Explanation
Choice A reason: A respiratory rate of 24 breaths/min is within the normal range for a 3-year-old child. It does not indicate the degree of hydration or dehydration of the child.
Choice B reason: A heart rate of 130/min is above the normal range for a 3-year-old child, which is 80 to 120/min. It may indicate dehydration, fever, pain, or anxiety. It does not indicate the effectiveness of oral rehydration therapy.
Choice C reason: A urine specific gravity of 1.015 is within the normal range for a child, which is 1.005 to 1.030. It indicates that the child's urine is adequately concentrated and that the child is well hydrated. It is a reliable indicator of the effectiveness of oral rehydration therapy.

Choice D reason: A capillary refill of greater than 3 seconds is abnormal and indicates poor peripheral perfusion. It may be a sign of dehydration, shock, or hypothermia. It does not indicate the effectiveness of oral rehydration therapy.
Correct Answer is D
Explanation
Choice A reason: Tremors are not a likely finding in a child with hyperglycemia, or high blood glucose. Tremors are more commonly associated with hypoglycemia, or low blood glucose, as the body releases adrenaline to stimulate the release of glucose from the liver. Tremors may also be caused by anxiety, caffeine, or certain medications.
Choice B reason: Shallow respirations are not a likely finding in a child with hyperglycemia, unless the child has developed diabetic ketoacidosis (DKA), a serious complication of diabetes that occurs when the body breaks down fat for energy and produces ketones, which are acidic substances that can cause metabolic acidosis. In DKA, the child may have rapid and deep breathing, also known as Kussmaul respirations, as the body tries to eliminate excess carbon dioxide and acid. However, DKA usually occurs when the blood glucose level is above 300 mg/dL, and the child may also have other signs and symptoms, such as nausea, vomiting, abdominal pain, fruity breath, and confusion.
Choice C reason: Pallor is not a likely finding in a child with hyperglycemia, as the blood flow to the skin is not affected by high blood glucose. Pallor is more commonly associated with anemia, shock, or hypoxia, which are conditions that reduce the oxygen-carrying capacity of the blood or the blood flow to the tissues.
Choice D reason: Lethargy is a likely finding in a child with hyperglycemia, as high blood glucose can cause dehydration, electrolyte imbalance, and impaired brain function. The child may feel tired, weak, and drowsy, and have difficulty concentrating or staying awake. Lethargy may also indicate that the child is at risk of developing DKA, which can lead to coma and death if not treated promptly.
