Choice A: Administer spironolactone

Spironolactone is a potassium-sparing diuretic used to manage heart failure and hypertension. However, the client’s potassium level is elevated at 5.3 mEq/L (normal range: 3.5 to 5 mEq/L) . Administering spironolactone could exacerbate hyperkalemia, leading to dangerous cardiac arrhythmias. Additionally, the client’s low blood pressure (89/60 mm Hg) and dehydration (indicated by dry skin and tenting) make the use of a diuretic inappropriate as it could further lower blood pressure and worsen dehydration .

Choice B: Administer an IV fluid bolus

The client presents with signs of dehydration (dry skin, tenting, low urine output) and hypotension (BP 89/60 mm Hg). An IV fluid bolus is anticipated to restore intravascular volume, improve blood pressure, and address

dehydration . This intervention is crucial to stabilize the client’s hemodynamic status and improve perfusion to vital organs .

Choice C: Obtain an x-ray of the right hip

The client reports pain in the right hip following a fall, which raises the suspicion of a fracture. An x-ray is essential to diagnose any potential fractures or dislocations, which are common in elderly patients after a fall 5.

Prompt imaging will guide appropriate management and prevent further complications .

Choice D: Administer an iron supplement

While the client has a history of iron-deficiency anemia and is on ferrous sulfate, the immediate need for iron supplementation is nonessential in the context of acute management of the fall and dehydration. The client’s hemoglobin (16 g/dL) and hematocrit (47%) are within normal ranges, indicating that anemia is currently well- managed . The focus should be on stabilizing the client’s acute condition.

Choice E: Obtain the client’s weight

Obtaining the client’s weight is anticipated as it is a critical parameter for calculating medication dosages, fluid requirements, and monitoring the client’s overall health status. Accurate weight measurement is particularly important in elderly patients with multiple comorbidities to ensure precise and safe medical management .

Choice F: Administer supplemental oxygen

The client’s oxygen saturation is 95% on room air, which is within the normal range (95-100%) . Therefore, administering supplemental oxygen is nonessential unless there is evidence of hypoxia or respiratory distress. The primary focus should be on addressing dehydration and hypotension.

Choice A reason: 0.9% sodium chloride, also known as normal saline, is not the best choice for interim fluid replacement when TPN is delayed. While it can maintain hydration and electrolyte balance, it does not provide the necessary calories that TPN supplies. TPN solutions are rich in dextrose, amino acids, and lipids, which are essential for patients who cannot receive nutrition through their gastrointestinal tract.

Choice B reason: Dextrose 5% in water (D5W) provides some calories but not enough to meet the nutritional needs of a patient who is dependent on TPN. D5W contains 5 grams of dextrose per 100 mL, providing 170 calories per liter. This is insufficient for patients who require high-calorie intake due to their inability to eat or absorb nutrients normally.

Choice C reason: Dextrose 10% in water (D10W) is the most appropriate choice for interim fluid replacement when TPN is delayed. D10W provides 10 grams of dextrose per 100 mL, offering 340 calories per liter. This higher concentration of dextrose helps to maintain the patient’s caloric intake and prevent hypoglycemia until the next TPN container is available.

Choice D reason: Lactated Ringer’s solution is primarily used for fluid and electrolyte replacement. It contains sodium, potassium, calcium, chloride, and lactate, but it does not provide the necessary calories that TPN supplies. Therefore, it is not suitable for maintaining the nutritional needs of a patient who is dependent on TPN.
