A nurse is applying a nitroglycerin transdermal patch for a client who has angina. Which of the following actions should the nurse take?

Choice A Reason:
Dark amber urine is incorrect. Dark urine can indicate concentrated urine, often seen in dehydration when the body is trying to conserve water.
Choice B Reason:
Decreased skin turgor is incorrect. Decreased skin turgor is a classic sign of dehydration, indicating that the skin lacks elasticity due to insufficient fluid intake or loss.
Choice C Reason:
Pink, frothy sputum is correct. Normal saline is a common intravenous solution used to treat dehydration. However, in some cases, especially when administered in excessive amounts, it can lead to fluid overload or pulmonary edema. This can manifest as pink, frothy sputum, indicating potential pulmonary congestion or edema, which is a serious adverse effect of fluid overload.
Choice D Reason:
Increased bowel sounds is incorrect. Increased bowel sounds can be seen in various conditions, including gastrointestinal disturbances or hyperactive bowel motility, but it's not typically associated with the adverse effects of normal saline administration.

Choice A Reason:
Nausea is incorrect. Nausea is a common side effect of many medications, including antibiotics like amoxicillin. While it can be a side effect of an allergic reaction, it's also a general symptom that can occur due to various reasons, such as gastrointestinal upset or the direct effects of the antibiotic on the stomach lining. Nausea alone is less specific for indicating an allergic reaction compared to severe symptoms like laryngeal edema.
Choice B Reason:
Insomnia is incorrect. Insomnia, or difficulty sleeping, is not a typical manifestation of an allergic reaction to amoxicillin. Allergic reactions usually involve more immediate and visible symptoms such as skin rash, itching, swelling, difficulty breathing, or in severe cases, anaphylaxis. Insomnia is not a common symptom associated with allergic responses to antibiotics.
Choice C Reason:
Laryngeal edema is correct. Laryngeal edema, or swelling of the larynx, is a serious symptom of an allergic reaction known as anaphylaxis. This severe allergic reaction can be life-threatening due to its potential to obstruct the airway, leading to breathing difficulties.
Choice D Reason:
Cardiac dysrhythmia is incorrect. While medications can sometimes affect heart rhythms, cardiac dysrhythmia is not a common symptom of an allergic reaction to amoxicillin. Allergic reactions tend to manifest with more immediate symptoms like skin reactions, respiratory issues, or swelling rather than primarily affecting the heart rhythm.
