Correct Answer: D

Rationale: The correct answer is D because floaters are a common and typically benign phenomenon caused by condensed vitreous fibers in the eye. A nurse should educate the patient that floaters are usually not significant and do not require immediate intervention. Option A is incorrect because counting the number of floaters is unnecessary. Option B is incorrect because presuming glaucoma without proper assessment is inappropriate. Option C is incorrect because seeing occasional floaters is a common and normal occurrence in many individuals.

Correct Answer: A

Rationale: The correct answer is A: "Are you aware of having any allergies?" This question is appropriate because the patient's symptoms of pale, grey, and swollen nasal mucosa suggest an allergic reaction. By asking about allergies, the nurse can gather important information to determine the cause of the symptoms. B: "Do you have an elevated temperature?" - This question is not directly related to the patient's nasal symptoms and does not address the likely allergic reaction. C: "Have you had any symptoms of a cold?" - While cold symptoms may present similarly to allergies, the patient's specific symptoms of pale, grey, and swollen nasal mucosa are more indicative of an allergic reaction. D: "Have you been having frequent nosebleeds?" - This question does not directly address the patient's current symptoms and is not likely related to the nasal mucosa appearance described.

Correct Answer: A

Rationale: The correct answer is A: poor vision. In the 20/80 visual acuity notation, 20 represents the test distance in feet, and 80 represents the line on the eye chart that the patient can read. Therefore, a person with 20/80 vision can only see at 20 feet what a person with normal vision can see at 80 feet. This indicates poor vision as the patient's visual acuity is significantly below normal. Summary: - Choice B (acute vision) is incorrect as 20/80 vision indicates poor vision, not exceptional sharpness. - Choice C (normal vision) is incorrect as 20/80 vision is below normal range. - Choice D (presbyopia) is incorrect as presbyopia is a condition related to aging and difficulty focusing on close objects, not specifically indicated by 20/80 vision.

Correct Answer: C

Rationale: The correct answer is C, parotid and submandibular glands. The parotid and submandibular glands are the two pairs of salivary glands that are accessible for examination in the face. The parotid gland is located near the ear, while the submandibular gland is located under the jaw. The other choices are incorrect because: A: Occipital and submental glands are not salivary glands accessible for examination in the face. B: Parotid gland is correct, but jugulodigastric gland is not a salivary gland. D: Submandibular gland is correct, but occipital gland is not a salivary gland.

Correct Answer: C

Rationale: The correct answer is C because as individuals age, there is a natural decrease in skin elasticity, subcutaneous fat, and moisture content in the skin. These factors contribute to the bones becoming more noticeable in the face. Choice A is incorrect because diets low in protein and high in carbohydrates do not directly cause enlargement of facial bones. Choice B is incorrect as the use of a specific moisturizer does not directly impact the visibility of facial bones. Choice D is incorrect because facial skin actually loses elasticity with age, leading to less taut skin and more prominent bones.
