A patient has been diagnosed with angina and will be given a prescription for sublingual nitroglycerin tablets. When teaching the patient how to use sublingual nitroglycerin, the nurse will include which instruction?

Correct Answer: C

Rationale: When teaching a patient how to use sublingual nitroglycerin tablets, the nurse should include the instruction that if the chest pain is not relieved after one tablet, the patient should call 911 immediately. This is because persistent chest pain could indicate a more serious cardiac event, such as a myocardial infarction, that requires prompt medical attention. It is important for the patient to seek emergency help if the chest pain is not relieved after taking one sublingual nitroglycerin tablet. Taking multiple doses without relief of symptoms can be dangerous and delay appropriate medical intervention.

Correct Answer: C

Rationale: One major side effect to monitor in a patient taking Lithium for bipolar I disorder is the risk of seizures. Lithium is known to lower the seizure threshold, increasing the likelihood of seizures occurring, especially if the patient has any pre-existing risk factors for seizures. Therefore, it is critical to closely monitor patients on Lithium for any signs or symptoms of seizures and promptly address them if they occur to prevent any complications. Monitoring lithium levels and maintaining them within the therapeutic range can also help reduce the risk of seizures.

Correct Answer: D

Rationale: Digoxin toxicity can lead to serious complications, such as arrhythmias and heart failure. Digibind, also known as digoxin immune fab, is a specific antidote used to treat severe cases of digoxin toxicity. It works by binding to digoxin in the body and forming a complex that is then excreted through the kidneys, effectively reversing the toxic effects of digoxin. Naloxone is used to reverse opioid overdose, Vitamin K is used to reverse warfarin overdose, and Fluemanzil is not a medication used for reversing digoxin toxicity.

Correct Answer: A

Rationale: Ondansetron, commonly used to prevent nausea and vomiting, can be administered either orally (PO) or intravenously (IV). Both routes of administration are effective in delivering the medication to achieve the desired therapeutic effects. While options C (Subcutaneous) and D (IM) are not typically used for ondansetron administration, the correct answers are A (PO) and B (IV).

Correct Answer: B

Rationale: Anaphylaxis is a severe allergic reaction that can occur after exposure to penicillin or other antibiotics. It is considered a serious adverse reaction because it can be life-threatening. Symptoms of anaphylaxis may include difficulty breathing, hives, swelling of the face and throat, rapid heartbeat, and a drop in blood pressure. Immediate medical attention is required if an individual experiences anaphylaxis after taking penicillin.
