A nurse is assessing a client who has heart failure and a new prescription for metoprolol. Which of the following findings should the nurse identify as an adverse effect of the medication?

Choice A reason: Advising the client to avoid carbohydrates after exercise is not appropriate. Carbohydrates are necessary to replenish glycogen stores after exercise, and individuals with diabetes need to monitor their blood sugar levels to manage carbohydrate intake accordingly.

Choice B reason: Saying it is normal to feel exhausted after a morning run does not address the client's symptoms of diaphoresis, increased heart rate, and palpitations, which could be signs of hypoglycemia, a common risk for individuals with type 1 diabetes after exercise.

Choice C reason: While it's true that exercise can become easier with routine, this statement does not address the client's immediate concerns about their symptoms following exercise.

Choice D reason: Asking if the client decreased their insulin intake before exercising is an appropriate response. Individuals with type 1 diabetes need to adjust their insulin dosage to account for physical activity, which can significantly lower blood glucose levels.

Choice A reason: Laryngeal edema is a classic sign of anaphylaxis, a severe and potentially life-threatening allergic reaction. It can lead to difficulty breathing and requires immediate medical attention. Anaphylaxis can occur with any medication, including captopril, especially on initial exposure.

Choice B reason: Fever is not typically a sign of anaphylaxis. While it can be a symptom of various infections or inflammatory processes, it is not indicative of an immediate hypersensitivity reaction.

Choice C reason: Hypertension, or high blood pressure, is not a sign of anaphylaxis. In fact, during an anaphylactic reaction, blood pressure often drops significantly, a condition known as anaphylactic shock.

Choice D reason: Arrhythmia, or an irregular heartbeat, can be associated with various cardiac conditions but is not a specific indicator of anaphylaxis. While severe allergic reactions can affect heart rate, they are more likely to cause hypotension than arrhythmia.
