The client’s blood sugar this morning is 50 mg/dL. The client states they are cold, sweating, and clammy. Which nursing intervention is most appropriate?

Reasoning:

Choice A reason: Levothyroxine (T4) replacement requires TSH monitoring to ensure adequate dosing, as TSH reflects thyroid function. T3 replacement also requires monitoring, but T3 is less commonly used due to its short half-life. This statement is inaccurate, as TSH monitoring is essential for T4 therapy.

Choice B reason: The body converts levothyroxine (T4) to triiodothyronine (T3) via deiodinase enzymes in peripheral tissues, restoring both hormone levels. T3 replacement is unnecessary, as T4 provides a stable precursor for T3 production, making this statement accurate for explaining hypothyroidism treatment rationale.

Choice C reason: T3 and T4 can be administered together in specific cases (e.g., combination therapy) without becoming inactive. However, T4 alone is standard due to its longer half-life and conversion to T3. This statement is inaccurate, as it falsely claims biochemical incompatibility between the hormones.

Choice D reason: T3 is the active thyroid hormone, not an inactive precursor to T4. T4 is converted to T3, which binds receptors to regulate metabolism. This statement is inaccurate, as it reverses the roles of T3 and T4 in thyroid hormone physiology and therapy.

Choice A reason: Chronic kidney disease (CKD) does not primarily cause anemia by leaking red blood cells (RBCs) into urine. While hematuria may occur in some renal conditions, anemia in CKD results mainly from reduced erythropoietin production, not RBC loss. This statement is inaccurate, as it misrepresents the primary mechanism of anemia in CKD.

Choice B reason: Inflammation in CKD may contribute to anemia by suppressing erythropoiesis through cytokine release, but it does not directly attack RBCs. The primary cause is erythropoietin deficiency due to impaired renal function. This statement is inaccurate, as it overstates inflammation’s role and ignores the key hormonal mechanism in CKD-related anemia.

Choice C reason: High vascular pressure in CKD can damage kidneys but does not directly cause RBCs to burst (hemolysis). Anemia in CKD stems from reduced erythropoietin, not mechanical RBC destruction. This statement is inaccurate, as it incorrectly links hypertension’s renal effects to direct RBC damage, misrepresenting the anemia’s cause.

Choice D reason: CKD causes anemia due to reduced erythropoietin synthesis by damaged kidneys. Erythropoietin stimulates RBC production in bone marrow. In CKD, impaired renal function decreases erythropoietin, leading to anemia. This statement is accurate, as it correctly identifies the hormonal deficiency as the primary cause of low RBC counts in CKD.
