A nurse is caring for a patient on a medical-surgical unit.
A nurse is performing a fall risk assessment on a patient. Which of the following findings indicate that the patient is at increased risk for falls? Select all that apply
WBC Count
Parkinson’s disease
Potassium level on day 2
Furosemide
Low blood pressure
Correct Answer : B,C,D,E
Choice A: WBC Count
Reason: The white blood cell (WBC) count is not directly related to fall risk. WBC count is an indicator of the immune system’s response to infection or inflammation. In this case, the patient’s WBC count is within the normal range (5,000 to 10,000/mm³) on both days. Therefore, it does not contribute to an increased risk of falls.
Choice B: Parkinson’s disease
Reason: Parkinson’s disease significantly increases the risk of falls due to several factors. Patients with Parkinson’s often experience postural instability, which is the inability to maintain balance when standing or walking. This condition is a cardinal feature of Parkinson’s disease and can lead to frequent falls. Additionally, Parkinson’s patients may experience freezing of gait, where they suddenly cannot move their feet forward despite the intention to walk. This can cause them to fall. Other gait abnormalities, such as festinating gait (short, rapid steps) and dyskinesias (involuntary movements), also contribute to the increased fall risk.
Choice C: Potassium level on day 2
Reason: The patient’s potassium level on day 2 is 3.0 mEq/L, which is below the normal range of 3.5 to 5 mEq/L. Low potassium levels (hypokalemia) can lead to muscle weakness, cramps, and fatigue. These symptoms can impair the patient’s ability to maintain balance and increase the risk of falls. Hypokalemia can also cause abnormal heart rhythms, which can further contribute to the risk of falls.
Choice D: Furosemide
Reason: Furosemide is a diuretic medication used to treat conditions such as heart failure by reducing fluid buildup in the body. However, it can also cause orthostatic hypotension, a condition where blood pressure drops significantly when standing up. This can lead to dizziness, lightheadedness, and an increased risk of falls. Additionally, furosemide can cause electrolyte imbalances, such as low potassium levels, which can further contribute to fall risk.
Choice E: Low blood pressure
Reason: The patient’s blood pressure readings indicate orthostatic hypotension, with a significant drop from 128/56 mm Hg while sitting to 92/40 mm Hg while standing. Orthostatic hypotension is a common condition in patients with Parkinson’s disease and heart failure. It can cause dizziness, lightheadedness, and fainting when changing positions, increasing the risk of falls. The patient’s low blood pressure when standing is a clear indicator of increased fall risk.

Correct Answer is C
Explanation
Choice A reason:
Purple striations: Purple striations, or stretch marks, are more commonly associated with Cushing’s syndrome, which involves excess cortisol production. Addison’s disease, on the other hand, is characterized by insufficient cortisol and aldosterone production.
Choice B reason:
Hirsutism: Hirsutism refers to excessive hair growth in women in areas where hair is normally minimal or absent. It is not typically associated with Addison’s disease. Hirsutism is more commonly linked to conditions involving excess androgens, such as polycystic ovary syndrome (PCOS).
Choice C reason:
Hyperpigmentation: Hyperpigmentation, or darkening of the skin, is a hallmark symptom of Addison’s disease. This occurs due to increased production of melanocyte-stimulating hormone (MSH) as a byproduct of elevated adrenocorticotropic hormone (ACTH) levels. The skin changes are often most noticeable in areas exposed to friction, such as the elbows, knees, and knuckles.
Choice D reason:
Intention tremors: Intention tremors, which occur during purposeful movement, are not typically associated with Addison’s disease. These tremors are more commonly seen in neurological conditions such as multiple sclerosis or cerebellar disorders.
Correct Answer is D
Explanation
Choice A reason:
A client with a tracheostomy tube attached to humidified oxygen is not typically at risk for hypokalemia. The primary concerns for these clients are maintaining a patent airway, preventing infection, and ensuring adequate humidification to prevent mucus plugging.
Choice B reason:
A client with an indwelling urinary catheter to gravity drainage is not specifically at risk for hypokalemia. The main risks for these clients include urinary tract infections and ensuring proper catheter care to prevent blockages.
Choice C reason:
A client with a chest tube to water seal is primarily at risk for complications related to the chest tube itself, such as infection, pneumothorax, or improper drainage. Hypokalemia is not a common risk associated with chest tubes.
Choice D reason:
A client with a nasogastric tube to suction is at risk for hypokalemia. Continuous suctioning can lead to the loss of gastric contents, which contain potassium, leading to a decrease in potassium levels in the body. This can result in hypokalemia, which needs to be monitored and managed appropriately.
