Correct Answer: B

Rationale: The correct answer is B: Wear sunglasses. Dilated pupils are sensitive to light, so wearing sunglasses can help protect the eyes from excessive light exposure. Keeping the eyes closed (A) may provide temporary relief but does not protect the eyes from light. Avoiding driving for 8 hours (C) is important after certain eye procedures but not specifically related to dilated pupils. Avoiding caffeinated beverages (D) is unrelated to pupil dilation.

Correct Answer: B

Rationale: The correct answer is B: Ambulate with assistance. Ambulating helps prevent further bone loss and strengthens muscles, important for osteoporosis patients. Bedrest can worsen bone density loss. Encouraging fluids and providing a high-protein diet are important for overall health but do not directly address the weakness associated with osteoporosis.

Correct Answer: B

Rationale: The correct answer is B: Do not give the antibiotic. This is because the patient has a history of being "very sick" after taking erythromycin in the past, indicating a potential allergic reaction or severe adverse effects. The nurse should not administer the antibiotic to prevent harm to the patient. Choice A is incorrect as it can lead to a repeat adverse reaction. Choice C, giving half the dose, still exposes the patient to potential harm. Choice D, discontinuing the antibiotic, is also incorrect as it implies the patient has already started the medication, which should not be the case given the history of adverse effects.

Correct Answer: A

Rationale: The correct answer is A: 25 g/day, initially. In this scenario, the client with Hashimoto's thyroiditis and a history of cardiac issues requires a cautious approach due to the risk of exacerbating cardiac conditions with thyroid hormone replacement. Starting with a low dose of 25 µg/day allows for careful monitoring of the client's response and prevents potential adverse effects on the cardiovascular system. Summary: B: Delayed until after thyroid surgery - Not appropriate as the client requires thyroid replacement therapy for Hashimoto's thyroiditis. C: 100 µg/day, initially - Too high of an initial dose and may lead to adverse cardiovascular effects. D: Initiated before thyroid surgery - Not relevant to the client's situation as there is no indication for thyroid surgery mentioned in the question.

Correct Answer: D

Rationale: The correct answer is D because a normal corneal light reflex involves light being reflected at the same spot in both eyes. This indicates that both eyes are aligned properly and focusing light in the same direction. Choice A is incorrect because it refers to accommodation, not the corneal light reflex. Choice B is incorrect as convergence is related to eye movement, not the corneal light reflex. Choice C is incorrect as pupil constriction in response to light is known as the pupillary light reflex, not the corneal light reflex.
