The nurse should identify that this is a manifestation of which of the following visual impairments?

A.

Cataracts.

B.

Diabetic retinopathy.

C.

Glaucoma.

D.

Macular degeneration.

Answer and Explanation

The Correct Answer is A

The correct answer is choice A. Cataracts are a cloudy, opaque area over the  lens of one eye that can impair vision

Choice B is wrong because diabetic retinopathy is a condition that affects the  blood vessels of the retina, not the lens. It can cause blurred vision, floaters, or  vision loss 

Choice C is wrong because glaucoma is a condition that damages the optic nerve  due to high pressure in the eye. It can cause blind spots, halos around lights, or  vision loss 

Choice D is wrong because macular degeneration is a condition that damages  the macula, the central part of the retina. It can cause blurred or no vision in the  center of the visual field

Correct Answer is D

Explanation

McBurney’s point is located one-third of the distance from the right anterior superior iliac spine to the umbilicus. This is where the base of the appendix is attached to the cecum, which is part of the large intestine. When the appendix becomes inflamed or infected, it causes pain in this area.

Choice A is wrong because the left lower quadrant is where the sigmoid colon and part of the small intestine are located.

These organs are not related to appendicitis.

Choice B is wrong because the left upper quadrant is where the stomach, spleen, and part of the pancreas are located.

These organs are also not related to appendicitis.

Choice C is wrong because the right upper quadrant is where the liver, gallbladder, and part of the small intestine are located. These organs can cause pain in this area if they have problems, but not appendicitis

Correct Answer is A

Explanation

Hypothermia is a condition where the body temperature drops below 35°C (95°F) and affects the normal functioning of the body. Elderly people are more at risk for hypothermia because they have a lower muscle mass, a decreased

shiver reflex, and lower immunity. They also tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness.

Choice B. Normothermia is wrong because it means having a normal body temperature, which is around 37°C (98.6°F).

Choice C. Hyperthermia is wrong because it means having a high body temperature, which is above 37.5°C (99.5°F).

Hyperthermia can be caused by heat exposure, infection, inflammation, or certain medications.

Choice D. Malignant hyperthermia is wrong because it is a rare genetic disorder that causes a severe reaction to certain anesthetics or muscle relaxants.

It is not related to thermoregulation in elderly people.
