A nurse is caring for a client who has a respiratory illness that has resulted in chronic hypoxia. Which of these conditions can develop as a result of long-term hypoxia?

Cardiac enlargement

Exophthalmos

Gastric ulcerations

Urinary tract infections

Answer and Explanation

The Correct Answer is A

A. Cardiac enlargement: Chronic hypoxia leads to increased workload on the heart as it works harder to deliver oxygen to tissues. This can result in cardiac enlargement or right-sided heart failure due to pulmonary hypertension, a common consequence of long-term hypoxia.

B. Exophthalmos: Exophthalmos is protrusion of the eyes and is typically associated with thyroid disorders, such as Graves' disease, rather than chronic hypoxia.

C. Gastric ulcerations: While stress and certain medications can lead to gastric ulcerations, they are not directly caused by chronic hypoxia. Chronic hypoxia mainly affects the cardiovascular and pulmonary systems.

D. Urinary tract infections: Chronic hypoxia does not typically lead to urinary tract infections. UTIs are more commonly associated with factors such as poor hygiene, urinary obstruction, or immunosuppression.

Correct Answer is ["C","D"]

Explanation

A. Repeat blood serum potassium: While it’s important to monitor potassium levels, the immediate priority when preparing to administer potassium is ensuring safe administration practices, not rechecking levels before initiating therapy.

B. Educate client regarding high-potassium food sources: Client education is important for long-term management but is not a priority when preparing for intravenous potassium replacement in an acute setting.

C. Cardiac monitoring during infusion: Potassium affects cardiac conduction, and rapid correction can lead to arrhythmias. Continuous cardiac monitoring is necessary to detect any life-threatening arrhythmias during the infusion.

D. Ensure that the client's urine output is at least 1 mL/kg/hour: Adequate urine output ensures that the kidneys are functioning and capable of excreting excess potassium, reducing the risk of hyperkalemia.

E. Ensure potassium infusion is prepared with 5% dextrose solution: Potassium should not be mixed with dextrose, as it can increase insulin release, causing potassium to shift into cells and worsen hypokalemia.

A. Hepatitis B B. Cockroaches C. Radon D. Mold

Correct Answer is D

Explanation

A. Hepatitis B is a viral infection that affects the liver, not an environmental factor associated with asthma or allergies. Avoiding Hepatitis B would be unrelated to managing asthma or allergies.
B. Cockroaches can trigger asthma symptoms, particularly through their droppings and shed body parts, which are common allergens. However, while significant, mold is often a more pervasive and impactful trigger, especially in damp environments.
C. Radon is a radioactive gas that can increase the risk of lung cancer over time but is not directly linked to asthma or allergies. It is an environmental concern but not specifically for managing asthma or allergies.
D. Mold is a well-known allergen that can exacerbate asthma symptoms. Mold spores, which are often found in damp environments, can cause significant respiratory issues and should be avoided by individuals with asthma and allergies.
