A nurse is providing discharge teaching to a client following a cataract extraction. Which of the following instructions should the nurse include?

Correct Answer: C

Rationale: The correct answer is C: 'Avoid lifting more than 10 lb.' After a cataract extraction, the nurse should instruct the client to avoid lifting heavy objects to prevent increased intraocular pressure, which could lead to complications. Choices A, B, and D are incorrect. A - 'Bend at the waist when picking up objects' can increase intraocular pressure; B - 'Avoid lying on the operative side' is not a specific concern related to cataract extraction; D - 'Apply ice to the affected eye' is not a standard post-cataract extraction instruction.

Correct Answer: D

Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.

Correct Answer: C

Rationale: The correct answer is C: 'Increases cough production.' Guaifenesin is an expectorant that works by increasing cough production to help clear secretions from the airways. Option A is incorrect because guaifenesin does not decrease mucus production but rather helps to make the mucus easier to cough up. Option B is incorrect as guaifenesin does not reduce nasal congestion. Option D is incorrect because guaifenesin does not have any effect on reducing fever.

Correct Answer: B

Rationale: The correct answer is to 'Report a rash.' Metronidazole can cause severe adverse reactions like Stevens-Johnson syndrome, a life-threatening rash. It is crucial to educate the patient to report any rash immediately to prevent serious complications. Choices A, C, and D are incorrect because while they may be relevant to consider during metronidazole therapy, they are not the priority teaching point. Headaches can occur but are not as serious as a rash; avoiding sunlight is more related to doxycycline, not metronidazole; and taking with meals is a general instruction for some medications but not the priority teaching point for metronidazole.

Correct Answer: A

Rationale: The correct answer is A: Pregnancy status. Raloxifene is a pregnancy category X drug, which means it can cause serious birth defects. Therefore, it is crucial for the nurse to assess the client's pregnancy status before initiating therapy. Choice B, bone density, while important in osteoporosis management, is not a specific concern related to initiating raloxifene therapy. Choice C, calcium levels, and choice D, blood pressure, are not directly related to the initiation of raloxifene therapy in a female client with osteoporosis.
