The nurse is obtaining the health history from a client who was admitted with a platelet defect.
Which of the following information should be a priority for the nurse to obtain?

Choice A rationale

Ecchymosis and wet purpura indicate abnormal bleeding tendencies often observed in platelet defects. While these findings are relevant, they are secondary to identifying medications that could exacerbate platelet dysfunction. Medication history directly influences the management plan by addressing reversible causes of thrombocytopenia, emphasizing its priority over descriptive bleeding symptoms.

Choice B rationale

Upcoming dental or invasive procedures are relevant to thrombocytopenia risks due to potential bleeding complications. However, these appointments do not provide immediate insight into causative factors of the platelet defect. Determining medication use offers direct information regarding drug-related impacts on platelet function, prioritizing it for management and diagnostic purposes over procedural risks.

Choice C rationale

Over-the-counter and prescription medication use are critical to evaluate because certain drugs can induce or worsen platelet defects. For example, NSAIDs like aspirin inhibit platelet aggregation and contribute to bleeding risks. Establishing this information helps guide management by identifying reversible causes and reducing complications associated with defective platelet function.

Choice D rationale

Family and genetic history offer valuable insights into inherited platelet disorders but are less immediately actionable for addressing acute platelet defects. Medications causing or contributing to thrombocytopenia present modifiable factors, prioritizing their identification over hereditary predispositions. Addressing medication-induced platelet dysfunction provides practical management strategies for preventing bleeding complications. .

Choice A rationale

Magnesium and bilateral lower extremity ultrasounds are not primary diagnostic tests for hypertension-related target organ damage. Magnesium levels do not directly correlate with hypertension complications, and lower extremity ultrasounds mainly evaluate vascular issues, such as deep vein thrombosis, rather than organs affected by chronic hypertension.

Choice B rationale

Urinalysis assesses kidney function by detecting proteinuria, an indicator of renal damage due to hypertension. Blood chemistry provides electrolytes and renal function metrics, like creatinine (normal range: 0.6–1.2 mg/dL). A 12-lead ECG identifies left ventricular hypertrophy or arrhythmias linked to cardiac strain from persistent high blood pressure, a common sign of target organ damage.

Choice C rationale

Complete blood count evaluates overall health but does not specifically target organ damage related to hypertension. Electroencephalogram measures brain activity and is more relevant for neurological conditions, such as seizures, not complications from high blood pressure.

Choice D rationale

Troponin evaluates myocardial injury in acute settings like myocardial infarction, unrelated to chronic hypertension-induced organ damage. Calcium levels and partial thromboplastin time assess coagulation and bone health but do not directly indicate target organ involvement in hypertension.
