Correct Answer: D

Rationale: The correct answer is D. After cataract surgery, wearing an eye shield at night for 2 weeks is essential to protect the eye during the initial healing period. Choice A is incorrect because significant eye pain should not be expected for the first 2 days after surgery. Choice B is incorrect as bending at the waist can increase intraocular pressure, which should be avoided postoperatively. Choice C is incorrect as there is no need to avoid sleeping on the side of the body that was operated on after cataract surgery.

Correct Answer: B

Rationale: Correct Answer: The healthcare professional should review serum creatinine levels before administering metformin to assess kidney function. Metformin is excreted by the kidneys, and checking serum creatinine helps prevent lactic acidosis, a potential side effect in individuals with impaired renal function. Choice A: Potassium levels are not directly related to the administration of metformin. While monitoring potassium levels is important for some medications, it is not the priority when initiating metformin. Choice C: Sodium levels are not typically assessed specifically before starting metformin. It is not a routine lab test required prior to metformin administration. Choice D: Hemoglobin A1C reflects long-term blood sugar control and is not a lab test that needs to be reviewed before initiating metformin. It is used to monitor diabetes management over time, not for immediate medication administration considerations.

Correct Answer: B

Rationale: The correct answer is B. An apical pulse below 60/min indicates bradycardia, a potential sign of digoxin toxicity. The nurse should report this finding to the provider for further evaluation and possible adjustment of the digoxin dose. Choice A, a potassium level of 4.2 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not indicate toxicity. Choice C, a digoxin level of 1 ng/ml, is within the therapeutic range (0.5-2 ng/ml) and is not suggestive of toxicity. Choice D, constipation for 2 days, is not directly related to digoxin administration and would not require an immediate report to the provider.

Correct Answer: A

Rationale: An effective leader advocates for the unit's success and its members. Choice B is incorrect because prioritizing staff requests over client needs does not align with effective leadership, which should focus on client-centered care. Choice C is incorrect as sharing personal opinions to influence the group's values can be biased and may not reflect the best interest of the team. Choice D is incorrect because while providing client care is essential, effective leadership involves more than routine tasks and includes guiding and supporting the team.

Correct Answer: B

Rationale: The correct answer is B: Photosensitivity. Ciprofloxacin can cause photosensitivity, making the client more sensitive to sunlight. It is essential for the nurse to report this finding to the provider so that appropriate measures can be taken to prevent skin damage. Dry mouth, headache, and urinary retention are not typically associated with ciprofloxacin use and do not require immediate reporting to the provider in this scenario.
