Extract:
Question 1 of 5
The nurse is caring for a client with a history of chronic obstructive pulmonary disease (COPD).
Correct Answer: B
Rationale: Chronic COPD causes CO2 retention, leading to a compensated respiratory acidosis with low pH (7.32), high PaCO2 (50 mmHg), and low PaO2 (70 mmHg) due to impaired gas exchange. Normal or acute values are incorrect.
Question 2 of 5
A 14-year-old is going home with a permanent tracheostomy. Which comment by the child's mother indicates to the nurse that the parent needs more instruction?
Correct Answer: A
Rationale: Asking for a fixed suctioning schedule suggests misunderstanding, as suctioning is PRN based on need, indicating a need for further instruction.
Question 3 of 5
The home health care nurse is caring for a 30-year-old woman with type I diabetes mellitus.
Correct Answer: B
Rationale: Elevated morning blood glucose levels suggest the dawn phenomenon, where blood sugar rises in the early morning due to hormonal changes. Adding 3 units of NPH insulin at 10 PM addresses this by providing longer-acting insulin coverage. Reducing the diet, adding regular insulin, or eliminating the snack does not target the dawn phenomenon effectively.
Question 4 of 5
A 34-year-old man comes to the clinic for the results of a glycosylated hemoglobin assay (HbA1c). Which statement, if made by the client to the nurse, indicates an understanding of this procedure?
Correct Answer: C
Rationale: when RBCs are being formed, sugar is attached (glycosylated) and remains attached throughout the life of the RBC
Question 5 of 5
A client admitted with a severe head injury following an MVA is placed on a ventilator, and hyperventilation is maintained. The primary reason for maintaining hyperventilation is:
Correct Answer: D
Rationale: Hyperventilation reduces $\mathrm{CO}_2$, causing cerebral vasoconstriction, which decreases cerebral blood flow and intracranial pressure in head injuries.
