The nurse is teaching a client about preventing symptoms of thalassemia.
Which of the following information should the nurse include in the teaching?
"It is important to avoid exposure to cold climates.”.
"You need to consume an increased amount of oral fluids daily.”.
"Include iron and vitamin B12-rich foods in your diet each day.”.
"Be sure to check the list of medications and substances to avoid before starting anything new.”. . . .
The Correct Answer is D
Choice A rationale
Avoiding exposure to cold climates is not specific to thalassemia prevention. While cold environments may exacerbate general vasoconstriction, they do not influence the genetic and hematologic basis of thalassemia symptoms.
Choice B rationale
Increasing fluid intake does not directly address thalassemia pathophysiology. While hydration is vital, it does not correct the primary anemia or the compromised oxygen delivery stemming from abnormal hemoglobin synthesis.
Choice C rationale
Iron and vitamin B12-rich foods are beneficial for conditions involving deficiency anemia. However, thalassemia involves a genetic defect in hemoglobin chains, so excess iron could even result in iron overload complications.
Choice D rationale
Medications and substances that exacerbate hemolysis, such as sulfonamides or antimalarials, should be avoided in thalassemia. Awareness and prevention of exposure are key to minimizing symptoms and complications in affected individuals. .

Correct Answer is D
Explanation
Choice A rationale
Assessing for hypotension is not indicative of fluid overload. Hypotension is more likely associated with hypovolemia or hemorrhage, whereas fluid overload manifests as signs of hypervolemia, including elevated blood pressure and pulmonary edema.
Choice B rationale
Assessing for distention above the pubis area identifies bladder retention or obstruction but is not directly related to monitoring fluid overload. Fluid overload affects systemic circulation and organ function rather than localized distention.
Choice C rationale
Monitoring laboratory values for hypernatremia is not an effective strategy for detecting fluid overload. Hypernatremia occurs due to inadequate water intake rather than excessive fluid administration. Fluid overload is typically identified by signs such as pulmonary congestion and generalized edema.
Choice D rationale
Maintaining strict intake and output records is crucial in detecting fluid overload. It helps identify disproportionate fluid retention compared to urinary output, signaling hypervolemia. Continuous monitoring ensures timely adjustments in fluid administration and prevents complications. .
Correct Answer is D
Explanation
Choice A rationale
A low sodium, high-calorie diet does not directly address severe pain caused by renal colic. Dietary interventions are long-term strategies for kidney health but are not immediate priorities for acute pain relief. Renal colic pain requires prompt management with pharmacological interventions to alleviate severe discomfort. Adjusting dietary intake may support prevention but would not resolve the acute symptoms, emphasizing that this is not the first-line measure for this clinical situation.
Choice B rationale
Increasing fluid intake to 3–4 L/day is beneficial for flushing out kidney stones and preventing further stone formation. However, this intervention does not directly alleviate severe pain experienced during an episode of renal colic. While adequate hydration is crucial for long-term management, acute pain demands immediate pharmacological relief. Therefore, fluid intake implementation is secondary when compared to pain management priorities.
Choice C rationale
Tamsulosin (Flomax) is an alpha-blocker that promotes the passage of kidney stones by relaxing the smooth muscles of the ureter. Although effective in expediting stone passage, it does not provide immediate pain relief for severe renal colic. Its role is valuable for the resolution of the obstruction but does not address acute symptoms. Administering pain medication remains a priority to manage distress caused by colic episodes.
Choice D rationale
Morphine sulfate is an opioid analgesic that directly targets severe pain associated with renal colic. It binds to mu-opioid receptors in the central nervous system, producing analgesia and a calming effect. Its rapid onset and effectiveness in severe pain management make it the first prescription to implement. Pain relief improves the client's comfort and allows for addressing underlying causes of colic after stabilizing acute distress.
