A nurse is providing teaching to a client who is to undergo a cardiac catheterization. Which of the following findings is expected during the procedure?
Sensation of skin warmth
Increased salivation
Numbness and tingling of the extremities
Headache
The Correct Answer is A
A. Sensation of skin warmth. A warm or flushed sensation is common during cardiac catheterization, especially when contrast dye is injected. This is a normal and temporary response to the dye used in the procedure.
B. Increased salivation. Increased salivation is not a typical reaction during cardiac catheterization. It is not associated with the administration of contrast dye or catheter manipulation.
C. Numbness and tingling of the extremities. Numbness or tingling may indicate compromised circulation or nerve involvement, which is abnormal and should be reported immediately. It may suggest complications like arterial spasm or clot.
D. Headache. Headaches are not expected during a cardiac catheterization. If a headache occurs, especially a severe one, it should be evaluated further, as it could indicate a reaction or another complication.

Correct Answer is B
Explanation
A. "Place a warm, wet washcloth over your child's forehead and the bridge of their nose." Warm compresses may actually dilate blood vessels, which can worsen the bleeding. Cold compresses are preferred to help constrict vessels.
B. "Use your thumb and forefinger to apply pressure to the sides of your child's nose." This is the correct first-aid measure for epistaxis. The parent should pinch the soft part of the nose continuously for 10–15 minutes while the child leans forward.
C. "Have your child lie down and turn their head to the side for 10 minutes." Lying down can increase blood flow to the nose and may cause blood to be swallowed, which can lead to nausea or vomiting.
D. “Tell your child to blow their nose gently, and then sit down and tilt their head backward." Tilting the head back can cause blood to drain into the throat, increasing the risk of aspiration and stomach upset. Leaning forward is the proper position.
Correct Answer is D
Explanation
A. "You should take a second dose if there is no relief within fifteen minutes after the initial dose." The second dose of sumatriptan should not be taken sooner than 2 hours after the first dose if there is no relief or if the migraine returns. Taking it too soon increases the risk of adverse effects.
B. "You may experience low blood pressure while taking this medication." Sumatriptan more commonly causes hypertension, not hypotension. It can cause vasoconstriction, which may elevate blood pressure and poses risks, especially in clients with cardiovascular disease.
C. "You should have complete relief in six hours after taking this medication." Relief from sumatriptan is often experienced within 1–2 hours after administration. While not all clients achieve complete relief, the medication acts quickly, and six hours is not the expected timeframe.
D. “You may experience muscle cramps as a potential adverse effect of the medication." Muscle cramps or tightness in the chest, neck, or limbs can occur due to vasoconstriction caused by sumatriptan. This is a known side effect and should be reported if severe or persistent.
