Correct Answer: C

Rationale: In chronic bilateral glaucoma, peripheral visual field loss occurs due to elevated intraocular pressure, leading to the need to turn the head to compensate for the visual field deficit. This symptom is characteristic of advanced glaucoma. Choice A is incorrect as constant blurred vision is a common symptom but not specific to peripheral vision loss in glaucoma. Choice B is incorrect because specific visual field deficits are more common than complete loss on one side. Choice D is incorrect as seeing floaters (specks floating in the eyes) is associated with other eye conditions like posterior vitreous detachment, not glaucoma.

Correct Answer: B

Rationale: The correct answer is 'anti-HBs'. The presence of surface antibody to HBV (anti-HBs) indicates a successful response to the hepatitis B vaccine. Anti-HBs is a marker of immunity and protection against hepatitis B infection. Choices A, C, and D are incorrect because: A) HBsAg indicates current infection with hepatitis B virus, C) anti-HBc IgG suggests past infection or immunity, and D) anti-HBc IgM is a marker of acute hepatitis B infection.

Correct Answer: C

Rationale: The correct answer is 'Risk for Bleeding.' A patient with dementia may have impaired judgment and may be prone to falls or injuries, increasing the risk of bleeding while on heparin therapy. Monitoring for signs of bleeding is crucial in this situation. Choice A, 'Back Pain,' is not a common side effect of heparin. Choice B, 'Fever and Chills,' is not a typical side effect of heparin but may indicate other underlying conditions. Choice D, 'Dizziness,' is not a common side effect of heparin and is not the primary concern in this scenario.

Correct Answer: B

Rationale: The correct answer is 'Liver edge 3 cm below the costal margin.' Normally, the lower border of the liver is not palpable below the ribs, so this finding suggests hepatomegaly, which could indicate an underlying health issue. Tympany on percussion of the abdomen, bowel sounds of 20/minute in each quadrant, and aortic pulsations visible in the epigastric area are all within normal limits for a physical assessment and do not require immediate reporting to the healthcare provider.

Correct Answer: A

Rationale: Excess secretions from the tracheostomy tube can collect near the stomal opening and cause skin breakdown. Management of secretions through regular suctioning will keep the area clean and dry, minimizing skin irritation. Choice B, cleansing the site daily with povidone-iodine and water, is incorrect as it may lead to skin irritation due to the harshness of povidone-iodine. Choice C, avoiding tube ties to secure the tube, is also incorrect as securing the tube is essential for stability. Choice D, 'None of the above,' is incorrect as managing secretions through suctioning is crucial in preventing skin irritation.
