A nurse recently hired to the preoperative area learns that certain patients are at higher risk for venous thromboembolism (VTE). Which patients are considered to be at high risk? (Select all that apply.)

Morbidly obese patient

A woman who smokes and takes oral contraceptives or smoke

Wheelchair-bound patient

Patient with a humerus fracture

Patient who underwent a prolonged surgical procedure

Answer and Explanation

Correct Answer : A,B,E

A. Morbidly obese patient: Obesity is a known risk factor for VTE due to several reasons. Morbidly obese individuals often have impaired mobility, which can lead to venous stasis (sluggish blood flow in the veins). Additionally, obesity is associated with inflammation and changes in blood clotting factors, increasing the risk of developing blood clots in the veins.

B. A woman who smokes and takes oral contraceptives or smokes: Both smoking and oral contraceptive use are independent risk factors for VTE. Smoking can cause damage to blood vessels and alter blood clotting mechanisms, while oral contraceptives can increase the risk of blood clots due to hormonal changes.

C. Wheelchair-bound patient: While being wheelchair-bound alone may not always indicate a high risk for VTE, immobility is a significant risk factor for developing blood clots. Prolonged periods of immobility can lead to blood stasis in the veins, making wheelchair-bound patients susceptible to VTE, especially if other risk factors are present.

D. Patient with a humerus fracture: A humerus fracture on its own may not necessarily increase the risk of VTE significantly. However, if the fracture requires immobilization or surgery, especially if it affects the lower extremities or leads to prolonged immobility, the risk of VTE can increase due to decreased blood flow and stasis.

E. Patient who underwent a prolonged surgical procedure: Prolonged surgical procedures often involve anesthesia, immobility during surgery, and postoperative immobilization, all of which can contribute to venous stasis and increase the risk of developing VTE. Additionally, the surgical trauma itself can trigger inflammatory responses and alterations in blood clotting factors, further elevating the risk of blood clots.

Correct Answer is ["A","D","E"]

Explanation

A serum potassium level of 3.2 mEq/L indicates hypokalemia, which is a potential complication of inhibiting aldosterone secretion and release. Aldosterone plays a key role in potassium regulation in the body by promoting potassium excretion in the kidneys. When aldosterone secretion is inhibited, potassium excretion decreases, leading to an accumulation of potassium in the bloodstream and resulting in hypokalemia. Symptoms of hypokalemia may include muscle weakness, cramping, irregular heartbeat, and fatigue.

B. Urine output of 1,200 mL in the last 2 hours:

This option does not directly relate to complications of inhibiting aldosterone secretion. A urine output of 1,200 mL in the last 2 hours indicates adequate urine production, which is generally a positive sign. However, in the context of inhibiting aldosterone secretion, the nurse would be more concerned about decreased urine output due to potential renal effects.

C. Blood osmolality of 250 mOsm/kg (250 mmol/kg):

Blood osmolality within the normal range (usually around 275-295 mOsm/kg) is not directly associated with complications of inhibiting aldosterone secretion. Blood osmolality reflects the concentration of solutes in the blood and is regulated by various factors, including water balance, electrolyte levels, and hormonal regulation. Inhibiting aldosterone secretion primarily affects electrolyte balance rather than blood osmolality.

D. Urine output of 25 mL/hr:

A urine output of 25 mL/hr is considered low and may indicate decreased renal perfusion or impaired kidney function. Inhibiting aldosterone secretion can affect renal function and urine output, leading to decreased urine production. Reduced urine output can contribute to fluid and electrolyte imbalances and may be a concern in patients with inhibited aldosterone secretion.

E. Serum potassium level of 5.4 mEq/L:

A serum potassium level of 5.4 mEq/L indicates hyperkalemia, which is another potential complication of inhibiting aldosterone secretion. Aldosterone helps regulate potassium levels by promoting potassium excretion in the kidneys. When aldosterone secretion is inhibited, potassium excretion decreases, leading to an accumulation of potassium in the bloodstream and resulting in hyperkalemia. Symptoms of hyperkalemia may include muscle weakness, irregular heartbeat, nausea, and numbness or tingling.

A. Urine output is greater than 0.5 mL/kg/hr B. Serum hemoglobin is 11 gm/dL C. Breath sounds are clear bilaterally D. Heart rate is 122/min

Correct Answer is A

Explanation

A. Urine output is greater than 0.5 mL/kg/hr

During the fluid resuscitation phase of burn management, one of the primary goals is to maintain adequate tissue perfusion and organ function by ensuring sufficient fluid intake. The best method for assessing the results of fluid resuscitation is by monitoring urine output. A urine output of greater than 0.5 mL/kg/hr is indicative of adequate renal perfusion and kidney function, suggesting that fluid resuscitation is effective in maintaining tissue perfusion and preventing complications such as acute kidney injury.

B. Serum hemoglobin is 11 gm/dL

Serum hemoglobin levels can be affected by various factors, including fluid resuscitation, blood loss, and other medical conditions. While monitoring hemoglobin levels is important in overall patient assessment, it is not the best method specifically for assessing the results of fluid resuscitation during the initial phase of burn management.

C. Breath sounds are clear bilaterally

Clear bilateral breath sounds indicate adequate lung function and ventilation but may not directly reflect the effectiveness of fluid resuscitation in maintaining tissue perfusion. Lung sounds can be influenced by factors such as lung injury from smoke inhalation or mechanical ventilation settings, which may not correlate directly with fluid resuscitation outcomes.

D. Heart rate is 122/min

Heart rate can be influenced by various factors such as pain, stress, medications, and underlying medical conditions. While monitoring heart rate is important in assessing patient status, it is not the most reliable method for specifically evaluating the results of fluid resuscitation during the fluid resuscitation phase of burn management.
