Which statement best documents the situation when a client becomes extremely agitated after receiving a sedative?
An idiosyncratic drug effect.
A toxic drug effect.
An allergic drug response.
An unexpected drug interaction.
The Correct Answer is A
An idiosyncratic drug effect is an unpredictable and uncommon reaction to a drug that is not related to the dose, the pharmacology, or the patient’s allergy or intolerance. It may be caused by genetic factors, metabolic abnormalities, or interactions with other drugs or substances. An example of an idiosyncratic drug effect is paradoxical agitation or excitement after receiving a sedative.
B. A toxic drug effect is a harmful reaction to a drug that is related to the dose or the pharmacology of the drug. It may cause symptoms such as nausea, vomiting, drowsiness, confusion, or respiratory depression. A toxic drug effect is unlikely to cause agitation after receiving a sedative unless there is an overdose or a drug interaction that increases the level of the sedative in the blood.
C. An allergic drug response is an immunological reaction to a drug that is not related to the dose or the pharmacology of the drug. It may cause symptoms such as rash, itching, swelling, fever, or anaphylaxis. An allergic drug response is unlikely to cause agitation after receiving a sedative unless there is a severe anaphylactic reaction that affects the brain or the circulation.
D. An unexpected drug interaction is a modification of the effect of one drug by another drug or substance that is not predictable based on their pharmacology. It may cause an increase or a decrease in the efficacy or toxicity of one or both drugs. An unexpected drug interaction may cause agitation after receiving a sedative if there is a synergistic effect that enhances the central nervous system stimulation of another drug or substance (such as caffeine, cocaine, or amphetamines) or if there is an antagonistic effect that reduces the central nervous system depression of the sedative (such as flumazenil, naloxone, or physostigmine). However, these interactions are usually known and avoidable by checking the patient’s history and medication list.

Correct Answer is B
Explanation
“Tell me what your pain feels like.” This question allows the nurse to assess the quality of pain, which is one of the characteristics of pain that can help determine its cause and treatment. Quality of pain refers to how the client describes the pain, such as sharp, dull, burning, throbbing, etc.
Choice A is wrong because it assesses the intensity of pain, not the quality. Intensity of pain is how much the pain hurts on a scale of 0 to 10 or using other methods.
Choice C is wrong because it assesses the precipitating factors of pain, not the quality. Precipitating factors are events or activities that trigger or worsen the pain.
Choice D is wrong because it assumes a specific quality of pain without asking the client. The nurse should not suggest words to describe the pain, but rather let the client use their own words.
Correct Answer is A
Explanation
Cataracts are a condition where the lens of the eye becomes opaque, causing impaired vision. Blurred or cloudy vision is a common symptom of cataracts.
Some possible explanations for the other choices are:
Choice B. Burning sensation in the eye. This is not a typical symptom of cataracts, but it could indicate an infection, allergy, or dry eye syndrome.
Choice C. Inability to produce tears. This is also not a typical symptom of cataracts, but it could indicate a problem with the lacrimal glands or ducts that produce and drain tears.
Choice D. A swollen lacrimal gland. This is not a symptom of cataracts, but it could indicate an inflammation or infection of the lacrimal gland, which is located near the upper eyelid.
Normal ranges for visual acuity are 20/20 for normal vision and 20/40 for mild impairment. Visual acuity can be measured using a Snellen chart or other methods.
