A client newly diagnosed with angina pectoris has taken two sublingual nitroglycerin tablets for chest pain. The chest pain is relieved, but the client now reports a headache. The nurse interprets that this most likely represents which response?

An expected side effect of the medication

An allergic reaction to the nitroglycerin

A sign that the medication should not be used again

An indication of worsening cardiac condition

Answer and Explanation

The Correct Answer is A

Choice A reason: A headache is a common and expected side effect of nitroglycerin. Nitroglycerin causes vasodilation, which can lead to increased blood flow to the head and result in headaches. It is important to inform the client that this is a known side effect and to manage it with appropriate measures, such as taking analgesics.

Choice B reason: An allergic reaction to nitroglycerin would typically present with symptoms such as rash, itching, swelling, or difficulty breathing. A headache alone does not indicate an allergic reaction.

Choice C reason: A headache does not mean the medication should not be used again. It is a common side effect, and the benefits of nitroglycerin in relieving chest pain usually outweigh the discomfort of the headache. The nurse should educate the client on managing the headache while continuing the medication.

Choice D reason: A headache is not an indication of a worsening cardiac condition. It is a common side effect of the vasodilatory effects of nitroglycerin.

Correct Answer is A

Explanation

Choice A reason: This response acknowledges the client's feelings and validates their experience. It opens the door for the client to express their emotions and share their thoughts. This empathetic approach helps build trust and provides emotional support.

Choice B reason: Telling the client that it takes time to get over the loss of a loved one is a generalized statement that may not provide the support the client needs. It can come across as dismissive and may not encourage further conversation.

Choice C reason: Suggesting that the client try something to take their mind off their troubles can seem dismissive of their grief. It does not address the client's emotional needs or encourage them to talk about their feelings.

Choice D reason: While this response shows some understanding, it does not fully acknowledge the uniqueness of the client's situation. It is important to validate the client's feelings and encourage them to express their emotions.

A. Pyridostigmine B. Flumazenil C. Acetylcholine D. Atropine

Correct Answer is D

Explanation

Choice A reason: Pyridostigmine is a medication used to treat myasthenia gravis by inhibiting acetylcholinesterase, but it is not used as an antidote for edrophonium overdose. Pyridostigmine helps improve muscle strength by increasing the amount of acetylcholine available at the neuromuscular junction.

Choice B reason: Flumazenil is an antidote for benzodiazepine overdose and has no effect on edrophonium. It works by competitively inhibiting the actions of benzodiazepines on the GABA receptor.

Choice C reason: Acetylcholine itself is not used as an antidote for edrophonium overdose. Administering acetylcholine would not counteract the effects of excessive acetylcholinesterase inhibition caused by edrophonium.

Choice D reason: Atropine is the correct antidote for edrophonium overdose. Atropine is an anticholinergic drug that can counteract the excessive accumulation of acetylcholine caused by edrophonium, thereby alleviating symptoms such as bradycardia and muscle weakness.
