A nurse is collecting data from a client who has a respiratory disorder and displays manifestations of hypoxia. Which of the following findings should the nurse expect?
Bradypnea
Cyanosis
Pallor
Bradycardia
The Correct Answer is B
A. Bradypnea, or abnormally slow breathing, is not typically associated with hypoxia. Hypoxia usually triggers an increase in respiratory rate (tachypnea) as the body attempts to take in more oxygen to meet its needs.
B. Cyanosis, a bluish discoloration of the skin and mucous membranes, is a key sign of hypoxia. It occurs when there is insufficient oxygen in the blood, leading to a darker color of deoxygenated hemoglobin. Cyanosis is most commonly observed in the lips, fingertips, and toes.
C. Pallor, or paleness of the skin, can occur in various conditions but is not specific to hypoxia. It is more commonly associated with anemia or shock rather than low oxygen levels in the blood.
D. Bradycardia, or a slower-than-normal heart rate, is not typically a manifestation of hypoxia. Instead, hypoxia often causes tachycardia as the body attempts to increase oxygen delivery to tissues by pumping blood more quickly.

Correct Answer is A
Explanation
A. Smoking tobacco: Tobacco smoking is the most common risk factor for emphysema. Smoking leads to chronic inflammation and damage to the alveoli, which are key characteristics of emphysema.
B. Asthma: Although asthma can contribute to chronic respiratory issues, it is not the most common risk factor for emphysema. Emphysema is primarily linked to smoking rather than asthma.
C. Between 20 to 30 years of age: Emphysema is more commonly associated with older age, typically developing over many years of exposure to risk factors such as smoking. It is not primarily linked to being in the 20 to 30 age range.
D. Pollution: While air pollution can contribute to respiratory diseases, smoking is the most significant risk factor for emphysema. Pollution alone is less commonly the primary cause.
Correct Answer is C
Explanation
A. The excretion of calcium by the kidneys is related to electrolyte balance and bone health but does not directly contribute to hydrostatic pressure in the vasculature.
B. Osmotic pressure is the force exerted by solutes (such as plasma proteins) drawing water into the bloodstream, which opposes hydrostatic pressure. It does not directly contribute to hydrostatic pressure but rather counterbalances it.
C. Hydrostatic pressure is primarily generated by the force of the heart's contraction, which pushes blood through the arteries and capillaries. This pressure drives fluid out of the blood vessels into the surrounding tissues, a crucial process in nutrient and waste exchange.
D. Pressure applied by plasma proteins contributes to oncotic (colloid osmotic) pressure, not hydrostatic pressure. Oncotic pressure pulls fluid into the capillaries, opposing the outward force of hydrostatic pressure.
