The nurse is assessing a client's eyes and notes that when the client looks at a near object, the pupil constricts, but when the client looks at an object in the distance, the pupil dilates. The nurse should identify this finding as which condition?

Hyperopia.

Photophobia.

Myopia.

Accommodation.

Answer and Explanation

The Correct Answer is D

Choice A reason: Hyperopia, also known as farsightedness, is a condition where distant objects can be seen more clearly than near objects. It is caused by the eyeball being too short or the cornea having too little curvature. In this scenario, the client's ability to adjust and focus on near and distant objects is not indicative of hyperopia.

Choice B reason: Photophobia is an increased sensitivity to light. It can be caused by various eye conditions, infections, or even migraines. The client's ability to focus on objects at different distances does not correlate with sensitivity to light.

Choice C reason: Myopia, or nearsightedness, is the opposite of hyperopia. Individuals with myopia can see near objects clearly but have difficulty focusing on distant objects. The client's ability to focus on both near and far objects rules out myopia.

Choice D reason: Accommodation is the process by which the eye adjusts its focus from near to distant objects (or vice versa). This involves changes in the shape of the lens, controlled by the ciliary muscles. The client's ability to focus on objects at varying distances correctly describes the accommodation process, making it the appropriate answer.

Correct Answer is C

Explanation

Choice A reason: Symmetrical joint pain that is relieved with rest is more characteristic of osteoarthritis, not rheumatoid arthritis. RA typically involves persistent, symmetrical joint pain and inflammation.

Choice B reason: Unilateral pain in the weight-bearing joints is not characteristic of RA. Rheumatoid arthritis generally affects joints symmetrically on both sides of the body.

Choice C reason: Symmetrical joint pain is a hallmark of rheumatoid arthritis. RA causes inflammation and pain in multiple joints, typically affecting the same joints on both sides of the body.

Choice D reason: Hypoglycemia is not related to rheumatoid arthritis. RA primarily involves joint inflammation and systemic symptoms like fatigue and fever but does not directly impact blood sugar levels.

A. Pyridostigmine B. Flumazenil C. Acetylcholine D. Atropine

Correct Answer is D

Explanation

Choice A reason: Pyridostigmine is a medication used to treat myasthenia gravis by inhibiting acetylcholinesterase, but it is not used as an antidote for edrophonium overdose. Pyridostigmine helps improve muscle strength by increasing the amount of acetylcholine available at the neuromuscular junction.

Choice B reason: Flumazenil is an antidote for benzodiazepine overdose and has no effect on edrophonium. It works by competitively inhibiting the actions of benzodiazepines on the GABA receptor.

Choice C reason: Acetylcholine itself is not used as an antidote for edrophonium overdose. Administering acetylcholine would not counteract the effects of excessive acetylcholinesterase inhibition caused by edrophonium.

Choice D reason: Atropine is the correct antidote for edrophonium overdose. Atropine is an anticholinergic drug that can counteract the excessive accumulation of acetylcholine caused by edrophonium, thereby alleviating symptoms such as bradycardia and muscle weakness.
