A nurse is providing postoperative teaching to a client who had a coronary artery bypass graft due to arteriosclerosis. Which of the information should the nurse include in the teaching regarding exercise?
"If you experience angina, take a 10-minute rest period, then resume exercise."
"Stop exercising if your heart rate increases by 20 beats per minute from baseline."
"Limit your exercise to an indoor facility to avoid exposure to the sun."
"Begin by walking half a mile two times a day for the first week."
The Correct Answer is D
A) "If you experience angina, take a 10-minute rest period, then resume exercise."
It's important for clients to stop exercising immediately and consult a healthcare provider if they experience angina during exercise. Resting and then resuming exercise can be unsafe without medical advice, as angina indicates insufficient blood flow to the heart.
B) "Stop exercising if your heart rate increases by 20 beats per minute from baseline."
An increase in heart rate during exercise is expected, and stopping at a 20 BPM increase may be overly cautious. Clients should be taught to monitor for excessive fatigue or symptoms like dizziness, but a 20 BPM increase alone isn't necessarily a concern.
C) "Limit your exercise to an indoor facility to avoid exposure to the sun."
While excessive sun exposure can be a concern for some individuals, limiting exercise to indoors is unnecessary unless there are specific contraindications. Clients should be encouraged to exercise in environments they enjoy, with appropriate sun protection if outdoors.
D) "Begin by walking half a mile two times a day for the first week."
This recommendation is a reasonable starting point for postoperative exercise. Walking is a low-impact exercise that can help improve cardiovascular health gradually. Clients should gradually increase their activity level based on their tolerance and healthcare provider's advice.

Correct Answer is D
Explanation
A) Contact dermatitis: This condition results from an allergic reaction or irritation caused by contact with a substance, such as chemicals, detergents, or allergens. It is not a communicable skin infection and does not spread from person to person.
B) Actinic keratoses: These are rough, scaly patches on the skin caused by prolonged exposure to ultraviolet (UV) rays. They are considered precancerous lesions and are not contagious. They result from environmental factors rather than person-to-person transmission.
C) Psoriasis: This is a chronic autoimmune condition that leads to the rapid buildup of skin cells, causing scaling on the skin's surface. It is not contagious and does not spread through person-to-person contact. Psoriasis is an inherited condition influenced by immune system triggers.
D) Herpes zoster: Also known as shingles, this condition is caused by the reactivation of the varicella-zoster virus (the same virus that causes chickenpox). While shingles itself is not spread from person to person, the virus can be transmitted from a person with shingles to someone who has never had chickenpox, potentially causing chickenpox in the latter individual. The virus is spread through direct contact with the fluid from the blisters.
Correct Answer is B
Explanation
A. Apply dry heat to help the lesions scab over.: Applying dry heat is not a recommended treatment for herpes simplex lesions. Moist heat, such as sitz baths, can help alleviate discomfort and promote healing.
B. Take three sitz baths each day to alleviate symptoms.: Sitz baths can help soothe and clean the affected area, providing relief from pain and itching associated with herpes simplex virus lesions. This is an appropriate recommendation for symptom management.
C. Apply talcum powder to the perineal area to help the lesions dry.: Talcum powder is not recommended for herpes simplex lesions as it can irritate the skin and worsen symptoms. Keeping the area dry can be beneficial, but using powders is not advised.
D. You can resume intercourse with the use of natural membrane condoms.: Condoms may reduce the risk of transmission but do not eliminate it completely. It is generally advised to avoid sexual activity during an outbreak to prevent spreading the virus.
