ATI Nursing Care of Children
1. When transitioning from intravenous to oral morphine, what would the nurse anticipate regarding the oral dose in comparison to the intravenous dose to achieve equianalgesia?
- A. Same as the intravenous dose
- B. Greater than the intravenous dose
- C. One half of the intravenous dose
- D. One fourth of the intravenous dose
Correct answer: B
Rationale: When switching from intravenous to oral morphine, a higher oral dose is required to achieve equianalgesia due to significant metabolism from the first-pass effect. Choosing the same oral dose as the intravenous dose would provide less pain relief. Opting for a dose greater than the intravenous dose is necessary to achieve the same analgesic effect. Therefore, options A, C, and D are incorrect.
2. What is a common sign of moderate dehydration in children?
- A. Dry mucous membranes
- B. Normal capillary refill
- C. Hyperactive bowel sounds
- D. Edema
Correct answer: A
Rationale: Dry mucous membranes are a common sign of moderate dehydration in children, indicating a loss of bodily fluids. When a child is moderately dehydrated, the mucous membranes in the mouth and nose may appear dry. This condition can occur due to various factors such as vomiting, diarrhea, or inadequate fluid intake. Normal capillary refill (choice B) is not typically associated with dehydration; it is a measure of circulatory status. Hyperactive bowel sounds (choice C) can be present in conditions like gastroenteritis but are not specific to dehydration. Edema (choice D) is the retention of fluid in the body and is not a typical sign of dehydration.
3. The nurse is caring for a patient in metabolic alkalosis. The patient has an NG tube to low intermittent suction for a diagnosis of bowel obstruction. What drug would the nurse expect to find on the medication orders?
- A. Cimetidine
- B. Maalox
- C. Potassium chloride elixir
- D. ) Furosemide
Correct answer: Cimetidine
Rationale:
4. The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation is the most common cause of acute respiratory alkalosis. When a patient hyperventilates due to anxiety or other causes, they blow off excessive carbon dioxide, leading to a decrease in PaCO2 and a rise in pH. Choices A, C, and D are incorrect because hyperventilation leads to a decrease in PaCO2, causing respiratory alkalosis, not respiratory acidosis, metabolic acidosis, or metabolic alkalosis.
5. Elliot became widowed after nearly 40 years of marriage. He has convinced himself that no one will ever love him again. His irrational thinking has caused him to suffer from depression, and he rarely leaves his house. What perspective might best explain his behavior?
- A. Psychodynamic
- B. Behavioral
- C. Biological
- D. Cognitive
Correct answer: D
Rationale: The cognitive perspective might best explain Elliot's irrational thinking and resulting depression. In this case, Elliot's belief that he will never be loved again is a cognitive distortion, leading to depressive symptoms and social withdrawal. The psychodynamic perspective primarily focuses on unconscious processes and unresolved conflicts from the past, which do not directly address Elliot's current cognitive distortions. The behavioral perspective would focus on observable behaviors and how they are reinforced, which is not the central issue in this scenario. The biological perspective would examine the role of genetics, brain chemistry, and other physiological factors, which are not the primary cause of Elliot's behavior in this context.
