Answer to Question 1
D
Metabolic alkalosis results from acid loss from the body or an increase in levels of bicarbonate. The most common causes are vomiting and gastric suction. Respiratory acidosis results from respiratory diseases or other conditions that reduce alveolar ventilation (hypoventilation), pre-venting excretion of the carbonic acid continuously produced by cells. Metabolic acidosis results from conditions that increase metabolic acids in the body or decrease the amount of base (bicar-bonate). Diabetic ketoacidosis is a common cause of metabolic acidosis. Hyperventilation pro-duces respiratory alkalosis, which causes cerebrospinal fluid and brain cells to become alkalotic, decreasing the level of consciousness.
Answer to Question 2
A
This is the right task because the nurse delegated I&O, but not tracheostomy suctioning. The right task is one that you can delegate for a specific patient, such as tasks that are repetitive, re-quire little supervision, are relatively noninvasive, have results that are predictable, and have mi-nimal potential risk. Right direction/communication involves the following: Give a clear, concise description of the task, including its objective, limits, and expectations. Communication must be ongoing between the nurse and nursing assistive personnel during a shift of care. There is no right for an intervention. Right supervision includes the following: Provide appropriate moni-toring, evaluation, intervention as needed, and feedback. Nursing assistive personnel should feel comfortable asking questions and seeking assistance.
