As the nurse assesses a client’s blood pressure, the patient’s wrist severely flexes inward. The nurse questions the client’s response because this finding may indicate what condition?

Choice A reason: Hypernatremia, high blood sodium (normal 135–145 mEq/L), is indicated by the 158 mEq/L level. It results from water loss, causing dehydration (dry mucous membranes, low urine output) and neurological symptoms like confusion due to brain cell shrinkage. The symptoms and lab values align with hypernatremia in this elderly client.

Choice B reason: Hyperkalemia, high potassium (normal 3.5–5.0 mEq/L), is not indicated, as the potassium level is 4.8 mEq/L, within normal range. Hyperkalemia causes arrhythmias and muscle weakness, not confusion or dehydration signs. The primary issue is high sodium, pointing to hypernatremia, not potassium imbalance.

Choice C reason: Hyponatremia, low sodium, causes swelling and neurological symptoms like seizures. The client’s sodium of 158 mEq/L indicates hypernatremia, not hyponatremia. Dry mucous membranes and low urine output suggest water loss, not sodium dilution, making hyponatremia inconsistent with the clinical and lab findings.

Choice D reason: Hypokalemia, low potassium, causes muscle weakness and arrhythmias. The client’s potassium of 4.8 mEq/L is normal, and symptoms like confusion and dehydration point to hypernatremia, not potassium deficiency. The high sodium level and clinical presentation make hypokalemia an unlikely diagnosis in this case.

Choice A reason: Caregiver role strain addresses the burden on parents or guardians. While important, it is not the highest priority compared to the client’s direct health needs. Developmental issues in a child take precedence, as they can have long-term impacts on physical, cognitive, and social growth, requiring immediate intervention.

Choice B reason: Risk for delayed development is critical in pediatric clients, as it affects cognitive, physical, and emotional growth. Early identification and intervention can mitigate long-term consequences, such as learning disabilities or social deficits. This diagnosis takes priority, as it directly impacts the child’s health and future functioning, requiring urgent attention.

Choice C reason: Sleep deprivation can affect health and development but is less urgent than developmental delays, which have broader, long-term consequences. Sleep issues may contribute to developmental problems but are typically secondary. Addressing underlying causes, like developmental risks, often resolves related symptoms like poor sleep more effectively.

Choice D reason: Altered urinary elimination, such as incontinence, may indicate a medical issue but is generally less critical than developmental delays in a pediatric client. It may be a symptom of developmental issues but does not take precedence over addressing potential delays that impact overall growth and function.
