Which disorder would the nurse suspect in a patient complaining of intense headaches, bloodshot eyes, and blurred vision? This is considered a medical emergency.
Detached retina
Macular degeneration
Cataracts
Angle-closure glaucoma
The Correct Answer is D
Choice A reason: A detached retina is a serious condition that occurs when the retina, the light-sensitive layer of tissue at the back of the eye, separates from its underlying support tissue. It can cause vision loss or blindness if not treated promptly. However, it does not usually cause intense headaches or bloodshot eyes, but rather flashes of light, floaters, or a curtain-like shadow over the visual field.
Choice B reason: Macular degeneration is a common eye disorder that affects the macula, the central part of the retina that is responsible for sharp and detailed vision. It can cause blurred or distorted vision, especially in the center of the visual field. However, it does not usually cause intense headaches or bloodshot eyes, but rather difficulty reading, recognizing faces, or seeing colors.
Choice C reason: Cataracts are cloudy areas in the lens of the eye that can impair vision. They are usually related to aging, but can also be caused by other factors such as diabetes, trauma, or radiation. They can cause blurred or dim vision, sensitivity to light, or halos around lights. However, they do not usually cause intense headaches or bloodshot eyes, but rather gradual and painless vision loss.
Choice D reason: Angle-closure glaucoma is a type of glaucoma that occurs when the drainage angle of the eye becomes blocked, causing a sudden increase in the pressure inside the eye. It can damage the optic nerve and lead to permanent vision loss if not treated immediately. It can cause intense headaches, bloodshot eyes, blurred vision, nausea, vomiting, or seeing rainbow-colored rings around lights. It is a medical emergency that requires immediate attention.

Correct Answer is A
Explanation
Choice A reason: This statement is correct, as adjuvant medications are drugs that are not primarily intended for pain relief, but can enhance the analgesic effect of other pain medications. Examples of adjuvant medications are antidepressants, anticonvulsants, or corticosteroids.
Choice B reason: This statement is false, as adjuvant medications can have significant side effects, depending on the type and dose of the drug. Some common side effects are drowsiness, nausea, dry mouth, or weight gain.
Choice C reason: This statement is misleading, as adjuvant medications are not used instead of opioids, but rather as an adjunct to opioids or other analgesics. Adjuvant medications can help reduce the dose of opioids needed to achieve pain relief, but they do not replace them entirely.
Choice D reason: This statement is inaccurate, as adjuvant medications are not used to eliminate the side effects of opioid medications, but rather to treat the underlying cause or mechanism of pain. Adjuvant medications can target different types of pain, such as neuropathic, inflammatory, or visceral pain.
Correct Answer is ["B","C","D"]
Explanation
Choice A reason: This is incorrect because providing antiseptic mouthwash (such as Listerine) for the patient can worsen xerostomia, or dry mouth. Antiseptic mouthwash can contain alcohol, which can dry out the oral mucosa and reduce saliva production. Saliva is important for lubricating the mouth, preventing infections, and facilitating chewing and swallowing. Therefore, antiseptic mouthwash should be avoided or used sparingly in patients with xerostomia.
Choice B reason: This is correct because encouraging the patient to brush and floss teeth regularly can help prevent dental caries, gingivitis, and periodontitis, which are common complications of xerostomia. Xerostomia can increase the risk of oral infections and tooth decay, as saliva helps wash away food particles, bacteria, and plaque. Therefore, oral hygiene is essential for patients with xerostomia.
Choice C reason: This is correct because encouraging the patient to drink water frequently can help moisten the mouth and relieve the discomfort of xerostomia. Water can also help flush out food debris and bacteria, and prevent dehydration, which can exacerbate xerostomia. Therefore, water intake is beneficial for patients with xerostomia.
Choice D reason: This is correct because providing saliva substitutes can help mimic the functions of natural saliva and improve the symptoms of xerostomia. Saliva substitutes are artificial saliva products that contain water, electrolytes, and lubricants, such as glycerin, carboxymethylcellulose, or xylitol. They can be applied as sprays, gels, rinses, or lozenges, and can help lubricate the mouth, prevent infections, and facilitate chewing and swallowing. Therefore, saliva substitutes are useful for patients with xerostomia.
