Which of the following is usually the first symptom of a cataract that the nurse would expect a patient to report during assessment?

Correct Answer: B

Rationale: Blurring of vision is typically the first symptom of a cataract that the nurse would expect a patient to report during assessment. As a cataract develops, it causes clouding of the eye's lens, leading to a decrease in the clarity of vision. This blurriness can progress over time, impacting the patient's ability to see clearly. Other symptoms such as glare sensitivity, poor night vision, double vision, and color fading may also be present as the cataract progresses. Dry eyes, eye pain, and loss of peripheral vision are not typically the initial symptoms associated with cataracts.

Correct Answer: B

Rationale: The appropriate nursing intervention for a 19-year-old student experiencing symptoms of respiratory alkalosis related to an anxiety attack is to have him breathe into a paper bag. Breathing into a paper bag can help increase the level of carbon dioxide in the body, which can help correct respiratory alkalosis. This technique helps to rebalance the level of carbon dioxide in the blood and alleviate the symptoms of alkalosis caused by hyperventilation during the anxiety attack. It is important to monitor the student's condition and ensure that he is using the paper bag correctly to avoid any potential risks associated with this intervention. Additionally, providing reassurance and support during this episode can also be beneficial in helping the student to manage his anxiety and respiratory alkalosis.
