A critical care nurse is caring for a client diagnosed with acute pancreatitis. The nurse knows this client should be started on parenteral nutrition (PN) after what indications?

5% deficit in body weight compared to pre-illness weight and increased caloric need.

Significant risk of aspiration coupled with decreased level of consciousness.

Calorie deficit and muscle wasting combined with low electrolyte levels.

Inability to take in adequate oral food or fluids within 7 days.

Answer and Explanation

The Correct Answer is D

Choice A rationale

A 5% deficit in body weight and increased caloric need alone do not warrant the initiation of parenteral nutrition (PN). PN is typically reserved for situations where oral or enteral feeding is not feasible or safe.

Choice B rationale

Significant risk of aspiration and decreased level of consciousness may necessitate alternative feeding methods, such as enteral feeding via a nasogastric or gastrostomy tube. PN is considered when enteral feeding is not possible.

Choice C rationale

Calorie deficit, muscle wasting, and low electrolyte levels indicate malnutrition, but PN is initiated when other feeding methods are inadequate or unsafe.

Choice D rationale

Inability to take in adequate oral food or fluids within 7 days is a clear indication for initiating PN. This ensures the patient receives essential nutrients and prevents further deterioration of their nutritional status.

Correct Answer is A

Explanation

Choice A rationale

The parietal lobe is responsible for processing sensory information and spatial awareness, including proprioception (the sense of body position in space). Damage to the parietal lobe can affect these functions.

Choice B rationale

The temporal lobe is involved in processing auditory information and memory, not spatial awareness. Damage to this lobe would affect hearing and memory rather than proprioception.

Choice C rationale

The frontal lobe is associated with executive functions, such as decision-making, problem-solving, and motor control, but not primarily with spatial awareness. Damage to this lobe impacts cognitive and motor functions.

Choice D rationale

The occipital lobe is primarily responsible for processing visual information. Damage to this lobe affects vision rather than spatial awareness or proprioception.

A. Pinpoint pupils. B. Absence of pupillary response. C. Pupil reacts to light. D. Pupil reaction quick. E. Unequal pupils

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale

Pinpoint pupils can indicate opioid use or damage to the pons, a part of the brainstem. This finding warrants further evaluation to determine the underlying cause and appropriate intervention.

Choice B rationale

Absence of pupillary response suggests severe brain injury or brainstem dysfunction. It is a critical finding that requires immediate medical attention to address potential life-threatening conditions.

Choice C rationale

Pupil reaction to light is a normal response indicating intact cranial nerve function. This finding does not raise neurologic concerns and does not require further investigation.

Choice D rationale

Quick pupil reaction is a normal response and indicates healthy cranial nerve function. This finding is not associated with neurologic concerns.

Choice E rationale

Unequal pupils, or anisocoria, can indicate increased intracranial pressure, brain injury, or nerve damage. This finding requires prompt assessment and intervention to prevent further complications.
