The nurse is caring for a client with hypertension who is being assessed for possible target organ damage.
The nurse should monitor the results of which of the following diagnostic tests?

Magnesium and bilateral lower extremity ultrasounds.

Urinalysis, blood chemistry, and 12-lead electrocardiogram.

Complete blood count and electroencephalogram.

Troponin, calcium, and partial thromboplastin time.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is D

Explanation

Choice A rationale

Amlodipine, a calcium channel blocker, primarily acts on vascular smooth muscles to reduce blood pressure. It does not directly affect renal function or significantly increase urine output. This statement reflects a misunderstanding of the drug's mechanism of action.

Choice B rationale

Edema, a common side effect of amlodipine, is due to vasodilation and capillary leakage, particularly in lower extremities. However, sudden discontinuation of the medication may lead to rebound hypertension and should be avoided. Reporting side effects is crucial for alternative management.

Choice C rationale

Amlodipine does not necessitate routine potassium monitoring as it does not significantly affect potassium homeostasis. This requirement is more commonly associated with potassium-wasting diuretics or renin-angiotensin-aldosterone system modulators.

Choice D rationale

Constipation and abdominal pain, although less common, may occur due to gastrointestinal motility changes caused by smooth muscle relaxation. Prompt reporting ensures timely assessment and potential treatment modifications to enhance adherence.

Correct Answer is ["12"]

Explanation

Step 1 is (176 pounds ÷ 2.2 pounds/kg) × 10 mcg/kg/min = 800 mcg/min.

Step 2 is (800 mcg ÷ 1000 mcg/mg) × 250 mL = 0.2 mL/min.

Step 3 is 0.2 mL/min × 60 min = 12 mL/hour. Final answer: 12 mL/hour.
