Correct Answer: A

Rationale: Step-by-step rationale for why A is correct: 1. Retinal detachment causes traction on the retina. 2. Traction on the retina can stimulate photoreceptors. 3. Stimulation of photoreceptors can lead to perception of flashing lights. 4. Therefore, the characteristic symptom of retinal detachment is flashing lights in the visual field. Summary: B: Sudden eye pain is not a characteristic symptom of retinal detachment. C: Loss of color vision is not typically associated with retinal detachment. D: Colored halos around lights are more indicative of conditions like glaucoma or corneal edema, not retinal detachment.

Correct Answer: C

Rationale: The correct answer is C because in sensorineural hearing loss, the sound is heard better in the ear with poorer hearing due to damage to the inner ear or auditory nerve. This is because the brain perceives the sound as louder in the affected ear to compensate for the hearing loss. Choice A is incorrect as it describes the result for conductive hearing loss. Choice B is incorrect as it indicates normal hearing. Choice D is incorrect as it describes the result for a lateralizing conductive hearing loss.

Correct Answer: A

Rationale: The correct answer is A: Type I hypersensitivity reaction. This type of reaction involves the release of histamine from mast cells and basophils, leading to symptoms like hives. It is characterized by the involvement of IgE antibodies. In this case, the patient developed hives quickly after exposure to the allergen, indicating an immediate hypersensitivity reaction typical of Type I. Choices B, C, and D are incorrect because they are associated with different mechanisms and timeframes of hypersensitivity reactions. Type II involves antibody-mediated cell destruction, Type III involves immune complex deposition, and Type IV is a delayed-type hypersensitivity reaction mediated by T cells, none of which are consistent with the rapid onset of hives seen in this patient.

Correct Answer: C

Rationale: The correct answer is C: The patient has diabetes. Diabetes can lead to diabetic retinopathy, a common cause of low vision. By knowing the patient's medical history, the nurse can recommend appropriate low vision aids and refer the patient to an ophthalmologist for further evaluation and management. Incorrect choices: A: The patient uses OTC NSAIDs - NSAIDs are not relevant to managing low vision. B: The patient has a history of stroke - A history of stroke is not directly related to low vision. D: The patient has Asian ancestry - Ancestry is not a factor in managing low vision.

Correct Answer: A

Rationale: Correct Answer: A Rationale: Abdominal cramping in a patient on enteral feedings could indicate feeding intolerance. The nurse's initial action should be to slow down the rate of the tube feeding to allow the patient's gastrointestinal tract to adjust gradually. This helps reduce the risk of further complications and allows for better tolerance. Slowing the rate is a safe and effective intervention that can help alleviate the abdominal cramping without causing additional stress on the patient's digestive system. Summary of Incorrect Choices: B: Instilling cold formula is not a recommended practice and can potentially cause harm or discomfort to the patient. C: Changing to a high-fat formula may exacerbate the abdominal cramping as it can be harder to digest for some patients. D: Consulting with the healthcare provider about prokinetic medication should come after trying less invasive interventions such as slowing the rate of tube feeding.
