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 C
Explanation
A) "Gestational diabetes increases the risk of your baby having hemorrhagic disease after birth." Hemorrhagic disease of the newborn is typically related to vitamin K deficiency, not gestational diabetes. Thus, this response does not directly address the risks associated with gestational diabetes.
B) "Gestational diabetes increases the risk of your baby having a cleft lip or palate." Cleft lip and palate are congenital conditions that are more related to genetic and environmental factors during the early stages of pregnancy. Gestational diabetes does not increase the risk of these specific congenital abnormalities.
C) "Gestational diabetes increases the risk of your baby having hypoglycemia after birth." This is correct. Infants born to mothers with gestational diabetes are at risk for hypoglycemia shortly after birth due to the high levels of insulin produced in response to maternal hyperglycemia during pregnancy.
D) "Gestational diabetes increases the risk of your baby having a low birth weight." Gestational diabetes more commonly leads to macrosomia (large birth weight) rather than low birth weight. The excessive glucose levels in the mother’s blood can result in increased fetal insulin production, leading to increased growth and fat deposits.
Correct Answer is D
Explanation
A) A yellowed sclera:
A yellowed sclera is typically associated with jaundice, which is related to liver conditions, not acute angle-closure glaucoma. This symptom is not indicative of glaucoma.
B) Brisk pupil reactivity:
In acute angle-closure glaucoma, the pupil is often mid-dilated and sluggish to react to light due to increased intraocular pressure. Brisk pupil reactivity is not a characteristic finding in this condition.
C) Client reports a curtainlike obstruction over the visual field:
A curtainlike obstruction over the visual field is usually associated with retinal detachment, not acute angle-closure glaucoma. This description does not align with the symptoms of glaucoma.
D) Client reports seeing colored halos around lights:
Seeing colored halos around lights is a classic symptom of acute angle-closure glaucoma. This occurs due to the elevated intraocular pressure affecting the corneal surface and causing light diffraction. This manifestation is a key indicator of the condition.
