A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?

Choice A Reason:
Visual disturbances is the correct findings. In individuals taking digoxin, visual disturbances such as blurred or yellow-tinted vision can indicate early signs of medication toxicity. This symptom often requires prompt medical attention, as it can precede more severe complications.
Choice B Reason:
Sudden weight gain is not correct. While weight gain can be a symptom of worsening heart failure, it's not typically associated specifically with digoxin toxicity. It's more commonly related to fluid retention in heart failure.
Choice C Reason:
Potassium 4.4 mEq/L is not correct. This potassium level is within the normal range. Digoxin toxicity can be exacerbated by low potassium levels, but a normal potassium level doesn't directly indicate digoxin toxicity.
Choice D Reason:
Insomnia is not a typical early sign of digoxin toxicity. It's more commonly associated with issues like difficulty sleeping rather than being a direct symptom of digoxin toxicity.

Choice A Reason:
Giving the prescribed dose of clindamycin is not appropriate due to the reported penicillin allergy, which increases the risk of an allergic reaction.
Choice B Reason:
Obtain a prescription for an alternative antibiotic is correct. Given the client's reported allergy to penicillin, which is in the same antibiotic class as clindamycin (both are antibiotics that belong to the beta-lactam group), there is a higher risk of cross-reactivity and potential allergic reaction. Therefore, it's important to avoid administering clindamycin in such cases and seek an alternative antibiotic that does not have a similar chemical structure to penicillin to prevent an allergic reaction.
Choice C Reason:
Premeditating the client with epinephrine before administering the antibiotic is not a standard practice in this context. Epinephrine is used to treat severe allergic reactions but is not used as a preventive measure before administering antibiotics.
Choice D Reason:
Administering the clindamycin using a desensitization schedule might be an option in certain situations under the guidance of an allergist or immunologist, but it's not typically performed by nurses and requires a specific protocol and expertise in managing drug allergies. Obtaining an alternative antibiotic is a more appropriate and immediate action to avoid the risk of an allergic reaction in this scenario.
