Correct Answer: C

Rationale: Storing expressed milk in the refrigerator for up to 4 days is correct, as breast milk can be safely stored in a refrigerator (at 4°C or 39°F) for up to 4 days to maintain its quality and safety for the newborn.
Choice A is wrong because newborns should be fed every 2-3 hours (8-12 times in 24 hours) or on demand, not every 4-5 hours, to ensure adequate nutrition and stimulate milk production.
Choice B is wrong because limiting feedings to 10 minutes per breast may not allow the newborn to receive sufficient milk, especially hindmilk; feedings should continue until the newborn is satisfied (typically 10-20 minutes per side).
Choice D is wrong because supplementing with formula after each breastfeeding session is not routinely recommended, as it can reduce milk supply and interfere with establishing breastfeeding; supplementation should only be used if medically indicated.

Correct Answer: D

Rationale: Absence of breath sounds on the affected side is a critical finding that may indicate a pneumothorax, lung collapse, or chest tube malfunction, requiring immediate reporting to the provider.
Choice A is incorrect because tidaling (fluctuations) in the water seal chamber is a normal finding, indicating the chest tube is functioning and the lung is re-expanding.
Choice B is incorrect because continuous bubbling in the suction control chamber is expected when suction is applied, as it regulates the amount of suction.
Choice C is incorrect because drainage of 50 mL/hr is within the expected range for the first 24-48 hours post-thoracotomy and does not require immediate reporting unless excessive (>100 mL/hr).

Correct Answer: A

Rationale: Nystagmus (involuntary eye movements) is a common manifestation of multiple sclerosis due to demyelination affecting the optic nerve or cerebellar pathways, impacting vision and coordination.
Choice B is incorrect because multiple sclerosis typically causes hyperactive deep tendon reflexes due to upper motor neuron involvement, not hypoactive reflexes.
Choice C is incorrect because persistent nausea is not a hallmark symptom of multiple sclerosis; it may occur secondary to medications or other conditions.
Choice D is incorrect because fever is not typical unless the client has an infection or is experiencing a pseudoexacerbation triggered by heat.

Correct Answer: A

Rationale: Monitoring for signs of serotonin syndrome (e.g., agitation, tremors, hyperthermia) is critical with fluoxetine, an SSRI, as it increases serotonin levels, and overdose or drug interactions can cause this life-threatening condition.
Choice B is incorrect because fluoxetine is typically taken in the morning, as it can cause insomnia if taken at bedtime.
Choice C is incorrect because fluoxetine is more likely to cause weight loss or be weight-neutral in bulimia, not weight gain.
Choice D is incorrect because fluoxetine should not be discontinued abruptly, even if binge eating stops, as this can cause withdrawal symptoms or relapse; it requires provider guidance.

Correct Answer: A

Rationale: Monitoring blood pressure regularly is essential, as epoetin alfa, used to treat anemia in chronic kidney disease, can cause hypertension as a side effect, requiring close monitoring and potential antihypertensive therapy.
Choice B is wrong because epoetin alfa is administered by injection (subcutaneous or intravenous), not orally, so it is not taken with meals.
Choice C is wrong because epoetin alfa stimulates red blood cell production but does not directly increase urine output, which is typically reduced in chronic kidney disease.
Choice D is wrong because epoetin alfa should be stored in the refrigerator (2-8°C or 36-46°F), not at room temperature, to maintain stability.
