Question Solution

Correct Answer : A,B,C

Choice A: Increased Respiratory Rate

 

Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.

 

Choice B: Increased Heart Rate

 

An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.

 

Choice C: Increased Blood Pressure

 

Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.

 

Choice D: Increased Hematocrit

 

Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.

 

Choice E: Increased Temperature

 

Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.

Correct Answer is B

Explanation

Choice A: Tachycardia

Tachycardia, defined as a heart rate exceeding 100 beats per minute, can affect the accuracy of pulse oximetry readings. When the heart beats too quickly, it may not fill with enough blood between beats, leading to reduced perfusion and oxygen delivery to tissues. However, while tachycardia can influence the readings, it is not the most significant factor compared to hypotension.

Choice B: Hypotension

Hypotension, or low blood pressure, significantly impacts pulse oximetry accuracy. When blood pressure is low, there is reduced perfusion to peripheral tissues, including the extremities where pulse oximeters are typically placed. This reduced perfusion can lead to inaccurate readings, as the device may not detect sufficient blood flow to measure oxygen saturation accurately. Hypotension is a critical factor that can alter pulse oximetry values, making it the most relevant choice.

Choice C: Tachypnea

Tachypnea, or rapid breathing, can affect oxygen levels in the blood but does not directly interfere with the pulse oximeter’s ability to measure oxygen saturation. While it indicates respiratory distress and can lead to hypoxemia, the pulse oximeter can still provide accurate readings unless accompanied by other factors like low perfusion.

Choice D: Fever

Fever can cause peripheral vasodilation, which might theoretically affect pulse oximetry readings by altering blood flow to the extremities. However, this effect is generally minimal compared to the impact of hypotension. Fever alone is unlikely to cause significant inaccuracies in pulse oximetry measurements.

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

Explanation

Choice A Reason:

Weight loss is a common symptom of hyperthyroidism. This condition speeds up the body’s metabolism, causing the body to burn calories more quickly than usual. Despite an increased appetite, individuals with hyperthyroidism often experience significant weight loss. This symptom is a direct result of the overproduction of thyroid hormones, which increases the metabolic rate.

Choice B Reason:

Intolerance to cold is not typically associated with hyperthyroidism; it is more commonly a symptom of hypothyroidism. Hyperthyroidism usually causes heat intolerance due to the increased metabolic rate, which raises the body’s temperature. Therefore, this choice is not relevant to hyperthyroidism.

Choice C Reason:

An elevated systolic blood pressure can be a symptom of hyperthyroidism. The increased levels of thyroid hormones can cause the heart to work harder, leading to higher blood pressure. This symptom is important to monitor as it can lead to further cardiovascular complications if left untreated.

Choice D Reason:

A heart rate of 90 bpm is within the normal range for adults and is not specifically indicative of hyperthyroidism. Hyperthyroidism typically causes a rapid or irregular heartbeat, often exceeding 100 bpm. Therefore, this choice does not accurately reflect a clinical manifestation of hyperthyroidism.

Choice E Reason:

Increased fatigability is a common symptom of hyperthyroidism. Despite the increased metabolic rate, individuals with hyperthyroidism often feel tired and weak. This paradoxical symptom occurs because the body’s systems are overworked and cannot sustain the heightened activity levels, leading to fatigue.
