A nurse is teaching a client who has venous insufficiency due to deep-vein thrombosis. Which of the following Instructions should the nurse include in the teaching?

A) A yellowed sclera:
A yellowed sclera is typically associated with jaundice, which is related to liver conditions, not acute angle-closure glaucoma. This symptom is not indicative of glaucoma.

B) Brisk pupil reactivity:
In acute angle-closure glaucoma, the pupil is often mid-dilated and sluggish to react to light due to increased intraocular pressure. Brisk pupil reactivity is not a characteristic finding in this condition.

C) Client reports a curtainlike obstruction over the visual field:
A curtainlike obstruction over the visual field is usually associated with retinal detachment, not acute angle-closure glaucoma. This description does not align with the symptoms of glaucoma.

D) Client reports seeing colored halos around lights:
Seeing colored halos around lights is a classic symptom of acute angle-closure glaucoma. This occurs due to the elevated intraocular pressure affecting the corneal surface and causing light diffraction. This manifestation is a key indicator of the condition.

A) Sensorineural deafness
This is a possible complication of mumps but not a symptom indicating the illness stage. It can occur after the infection and does not reflect the active phase of the disease.

B) Maculopapular rash
This type of rash is not typically associated with mumps. It may indicate other viral infections, such as measles or rubella, rather than mumps.

C) Swelling of the parotid glands
Swelling of the parotid glands is a hallmark symptom of the illness stage of mumps. This swelling typically appears a few days after the onset of other symptoms like fever and malaise and signifies the active phase of the infection.

D) Nuchal rigidity
Nuchal rigidity can occur if there is mumps-related meningitis, but it is not a typical sign of the initial illness stage. It indicates potential complications involving the central nervous system.
