A nurse is collecting data from a 5-month-old infant who has increased intracranial pressure (ICP) resulting from hydrocephalus. Which of the following manifestations should the nurse expect?

A. Cyanosis with crying: Cyanosis is less common in isolated PDA and more indicative of other congenital heart defects. PDA usually results in increased pulmonary blood flow and may not directly cause cyanosis, especially in less severe cases.

B. Weak pulses: PDA typically causes increased pulmonary blood flow and can result in bounding pulses rather than weak ones. Weak pulses are more indicative of reduced cardiac output, which is not characteristic of PDA.

C. Chronic hypoxemia: Chronic hypoxemia is less associated with PDA and more common in cyanotic heart defects where oxygenated and deoxygenated blood mix. PDA primarily affects the volume of blood flow to the lungs and may not lead to hypoxemia unless complicated by other conditions.

D. Machine-like murmur: A characteristic feature of PDA is a continuous, machine-like murmur caused by turbulent blood flow between the aorta and the pulmonary artery. This murmur is a hallmark sign of PDA and is typically heard during auscultation.

Inject insulin in the deltoid muscle: Insulin is administered subcutaneously, not intramuscularly. Common sites for insulin injection include the abdomen, thighs, and upper arms.

B. Take glyburide with breakfast: Glyburide is an oral hypoglycemic agent used for type 2 diabetes, not type 1 diabetes. Adolescents with type 1 diabetes require insulin.

C. Obtain an influenza vaccine annually: People with diabetes are at higher risk for complications from influenza, so annual vaccination is recommended to prevent illness.

D. Administer glucagon for hyperglycemia: Glucagon is used to treat severe hypoglycaemia, not hyperglycaemia. For hyperglycemia, insulin administration and monitoring blood glucose levels are key.
