A patient is intubated and placed on a mechanical ventilator. Which symptom indicates increased intracranial pressure?
Increased respirations.
Widened pulse pressure.
Prolonged capillary refill.
Decreased blood pressure.
The Correct Answer is B
Choice A rationale:
Increased respirations are not a specific symptom of increased intracranial pressure (ICP). They might occur due to other respiratory or metabolic issues.
Choice B rationale:
Widened pulse pressure (the difference between systolic and diastolic blood pressure) is a sign of increased ICP. It results from increased systolic pressure due to the body's attempt to compensate for the rising pressure within the skull.
Choice C rationale:
Prolonged capillary refill is indicative of decreased peripheral perfusion or shock, which can be caused by various factors but is not directly related to ICP.
Choice D rationale:
Decreased blood pressure is not a consistent symptom of increased ICP. In fact, widened pulse pressure is more characteristic.

Correct Answer is B
Explanation
Choice A rationale:
Administering pancreatic enzymes between meals may not provide the necessary digestive support when food is introduced to the gastrointestinal tract. These enzymes are meant to aid in digestion, so administering them between meals might not be as effective as when taken in conjunction with food.
Choice B rationale:
Administering pancreatic enzymes before meals is the most appropriate time because it helps replace the missing enzymes in patients with cystic fibrosis. These enzymes aid in breaking down food and absorbing nutrients, compensating for the deficient pancreatic function. By giving the enzymes before meals, the body has the necessary support to digest the incoming food.
Choice C rationale:
While administering enzymes during meals might seem logical, it's actually less effective. The enzymes need time to mix with the ingested food before it enters the small intestine, where digestion primarily occurs.
Choice D rationale:
Administering pancreatic enzymes after meals wouldn't be as effective because the enzymes need to be present when food enters the stomach and begins the digestive process.
Correct Answer is D
Explanation
Choice A rationale:
Performing passive range-of-motion exercises could worsen the bleeding in a patient with hemarthrosis due to hemophilia. Immobilization minimizes movement, reducing the risk of bleeding.
Choice B rationale:
While oxygen administration might be indicated in certain situations, it's not the primary intervention for hemarthrosis. The focus should be on preventing further bleeding and complications.
Choice C rationale:
Elevating the head of the bed is generally recommended for improving oxygenation, but it's not the primary concern in managing hemarthrosis.
Choice D rationale:
Immobilizing the affected joint is crucial to prevent movement that could exacerbate bleeding. This approach is aimed at minimizing damage and controlling bleeding in a patient with hemophilia.
