nurse is caring for a client who is newly-admitted and has angina. The client asks the nurse, "Why am I taking nitroglycerin?" Which of the lowing responses should the nurse make?

"Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart."

"Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration."

"Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath."

"Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries."

Answer and Explanation

The Correct Answer is A

A. "Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart." Nitroglycerin works by dilating the coronary arteries, increasing blood flow and oxygen delivery to the heart muscle, thereby reducing angina.

B. "Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration." Nitroglycerin does not have an antiemetic function or impact nausea and vomiting.

C. "Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath." Nitroglycerin is not a bronchodilator. It does not act on the airways but instead works on blood vessels.

D. "Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries." Nitroglycerin does not dissolve blood clots. Thrombolytic agents are used for clot dissolution, not nitroglycerin.

Correct Answer is B

Explanation

A. Keep the affected knee flexed. Flexing the knee for prolonged periods can impede venous return and increase the risk of thrombosis. The knee should be extended, not flexed.

B. Encourage increased fluid intake. Encouraging fluid intake helps to prevent dehydration, which is a risk factor for blood clot formation. Adequate hydration helps keep the blood less viscous and reduces the risk of DVT.

C. Massage the client's calf on the affected side. Massaging the calf could dislodge a clot if one is present, leading to serious complications such as a pulmonary embolism. This is contraindicated.

D. Promote bed rest for 5-10 days. Early ambulation and movement are key to preventing DVT after surgery. Prolonged bed rest increases the risk of DVT due to venous stasis.

A. "Was your son born with this cardiac defect?" B. "Has your son had a sore throat recently?" C. "Has your child had any injuries recently?" D. "Are you aware that your son will have to be in isolation?"

Correct Answer is B

Explanation

A. "Was your son born with this cardiac defect?" Rheumatic fever is an acquired condition, often following a streptococcal throat infection, not a congenital (born with) cardiac defect.

B. "Has your son had a sore throat recently?" Rheumatic fever commonly follows a streptococcal throat infection, so asking about a recent sore throat is relevant and important for diagnosis.

C. "Has your child had any injuries recently?" Recent injuries are unrelated to the development of rheumatic fever and are not a pertinent question.

D. "Are you aware that your son will have to be in isolation?" Isolation is not typically required for rheumatic fever, as it is not contagious in this stage.
