A nurse is assessing an infant who has heart failure. Which of the following findings should the nurse expect? (Select all that apply.)

Increased urinary output

Nasal flaring

Peripheral edema

Bradycardia

Answer and Explanation

Correct Answer : B,C

Choice A reason: Increased urinary output is not typically associated with heart failure. In fact, reduced urinary output may be expected due to decreased kidney perfusion.

Choice B reason: Nasal flaring is a sign of respiratory distress and can be expected in infants with heart failure as they struggle to maintain oxygenation.

Choice C reason: Peripheral edema is a common finding in heart failure due to fluid retention and poor circulation.

Choice D reason: Bradycardia is not a typical sign of heart failure in infants; tachycardia is more common. However, bradycardia can occur in advanced stages due to poor cardiac output.

Choice E reason: Cool extremities are indicative of poor perfusion, which is a consequence of decreased cardiac output in heart failure.

Correct Answer is A

Explanation

Choice A reason: A sweat chloride content of 85 mEq/L is indicative of cystic fibrosis, as normal values are below 30 mEq/L, and values above 60 mEq/L are diagnostic for cystic fibrosis.

Choice B reason: Hard, packed stools could be a sign of cystic fibrosis but are not as diagnostic as a sweat chloride test.

Choice C reason: Increased blood levels of fat-soluble vitamins are not typically associated with cystic fibrosis; patients often have deficiencies due to malabsorption.

Choice D reason: A chest x-ray negative for atelectasis does not indicate cystic fibrosis, as atelectasis can be present in many conditions.

A. Hyperventilation B. Increased blood pressure C. Decreased PaCO2 D. Unconsciousness

Correct Answer is D

Explanation

Choice A reason: Hyperventilation can be a sign of oxygen toxicity as the body attempts to balance oxygen and carbon dioxide levels.

Choice B reason: Increased blood pressure is not typically a direct sign of oxygen toxicity; it may be related to other underlying conditions.

Choice C reason: Decreased PaCO2 can be a result of hyperventilation, which is a compensatory mechanism in response to oxygen toxicity.

Choice D reason: Unconsciousness can be a severe sign of oxygen toxicity, indicating a high level of oxygen in the blood affecting brain function.
