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

Answer and Explanation

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. Bronchospasm occurs when there is inflammation, edema, and excess mucus: Bronchospasm in asthma is characterized by inflammation of the airways, edema of the airway walls, and increased mucus production, leading to constriction and obstruction of the airways.

B. Decreased mucus production contributes to airway constriction: In asthma, bronchospasm is associated with increased mucus production, not decreased. Excess mucus contributes to airway obstruction.

C. Inflammation is reduced due to airway diameter: Inflammation typically increases airway constriction rather than reducing it. The narrowed airway diameter is a result of inflammation, not a reduction in inflammation.

D. Airway obstruction occurs due to thinning mucus: Airway obstruction in asthma is due to thick, tenacious mucus, not thinning mucus. The mucus contributes to the blockage of the airways.

A. Report new-onset muscle weakness B. Increase consumption of apples and broccoli C. Avoid salt substitutes D. Report falls, due to high risk of osteoporosis

Correct Answer is A

Explanation

A. Report new-onset muscle weakness: Hypokalemia can cause muscle weakness, cramps, and fatigue, which are important symptoms that need to be monitored. Reporting these symptoms promptly is crucial because severe hypokalemia can lead to life-threatening complications, such as respiratory failure or cardiac arrhythmias.

B. Increase consumption of apples and broccoli: While fruits and vegetables like apples and broccoli are healthy, they are not particularly high in potassium. The client should be encouraged to consume potassium-rich foods such as bananas, oranges, potatoes, and spinach to help correct hypokalemia.

C. Avoid salt substitutes: Some salt substitutes contain potassium chloride, which can actually help increase potassium levels. However, this option might be recommended in certain conditions where potassium levels need to be carefully controlled, such as in renal failure, not in hypokalemia management.

D. Report falls, due to high risk of osteoporosis: Hypokalemia does not directly increase the risk of osteoporosis. Falls may occur due to muscle weakness, but this is not specifically related to osteoporosis. Therefore, reporting falls is not the primary concern in hypokalemia.
