A nurse is reinforcing teaching with a client who has angina pectoris about starting therapy with nitroglycerin sublingual tablets. Which of the following statements by the client indicates an understanding of the teaching?

"I will take the first tablet when the pain becomes severe."

"I will take no more than four tablets in 10 min."

"I will chew the tablet before swallowing."

"I will dial 911 if one tablet does not relieve my pain."

Answer and Explanation

The Correct Answer is D

A) "I will take the first tablet when the pain becomes severe.": This statement is incorrect because nitroglycerin should be taken at the onset of chest pain, not when it becomes severe. Early administration can help prevent the pain from worsening and reduce the risk of a heart attack. Waiting until the pain is severe may delay relief and increase the risk of serious complications.

B) "I will take no more than four tablets in 10 min.": This is incorrect as the standard protocol for nitroglycerin sublingual tablets typically involves taking one tablet every 5 minutes, up to three doses in 15 minutes, if needed. Taking four tablets in 10 minutes exceeds the recommended dosage and could lead to severe hypotension, dizziness, and fainting. It’s crucial to follow the prescribed limits to avoid these adverse effects.

C) "I will chew the tablet before swallowing.": This is incorrect because nitroglycerin sublingual tablets are designed to dissolve under the tongue for rapid absorption into the bloodstream. Chewing or swallowing the tablet would decrease its effectiveness and delay pain relief. The sublingual route allows the medication to bypass the digestive system and work quickly to relieve chest pain.

D) "I will dial 911 if one tablet does not relieve my pain.": This is the correct response. If chest pain is not relieved within 5 minutes after taking the first nitroglycerin tablet, it may indicate a more serious condition such as a heart attack. The client should call 911 to seek immediate medical assistance. Prompt action is critical in managing potential cardiac events and improving outcomes for the client.

Correct Answer is D

Explanation

A) To provide analgesia:
Aspirin is primarily used as an antiplatelet medication in the context of myocardial infarction (MI) and coronary artery disease (CAD). While aspirin can provide mild pain relief (analgesia), its main therapeutic effect in this scenario is not for pain management.

B) To reduce inflammation:
Aspirin does have anti-inflammatory properties, but its use in preventing cardiovascular events like myocardial infarction is primarily due to its antiplatelet effects rather than its anti-inflammatory properties.

C) To prevent fever:
Aspirin is sometimes used to reduce fever, but its role in preventing cardiovascular complications like clot formation after myocardial infarction is more crucial and unrelated to fever prevention.

D) To prevent blood clotting:
Aspirin inhibits platelet aggregation and reduces the risk of blood clot formation. This antiplatelet effect is beneficial in preventing further clot formation in coronary arteries, which is critical in the management of myocardial infarction and coronary artery disease.

A. "This medication prevents gastric acid secretion in the stomach." B. "This medication kills the bacteria which cause ulcers." C. "This medication neutralizes gastric acid after it is secreted." D. "This medication adheres to the ulcer and protects it from gastric acid."

Correct Answer is D

Explanation

A) "This medication prevents gastric acid secretion in the stomach":
Sucralfate does not affect gastric acid secretion. It works by forming a protective barrier over ulcers, adhering to the ulcer surface and shielding it from gastric acid and other digestive enzymes. This mechanism helps to promote healing of duodenal ulcers by providing a protective environment for the ulcer to heal without exposure to gastric acid.

B) "This medication kills the bacteria which cause ulcers":
Sucralfate does not possess antibacterial properties and does not target bacteria like Helicobacter pylori, which can cause ulcers. Its action is focused on providing a physical barrier to protect the ulcer from further damage.

C) "This medication neutralizes gastric acid after it is secreted":
Neutralizing gastric acid is the role of antacids, not sucralfate. Sucralfate acts by adhering to the ulcer site and forming a protective layer, which is distinct from the mechanism of neutralizing acid after secretion.

D) "This medication adheres to the ulcer and protects it from gastric acid":
Sucralfate forms a protective barrier over ulcers by adhering to the ulcer surface. This adherence helps to shield the ulcer from gastric acid and other digestive juices, promoting healing by creating an environment conducive to tissue repair.
