A nurse is preparing to administer the initial dose of penicillin G IM to a client. The nurse should monitor for which of the following as an Indication of an allergic reaction following the injection?

A) Increase in pulse rate - Methimazole is used to treat hyperthyroidism and would be expected to decrease, not increase, the pulse rate.

B) Warmer skin - Methimazole treatment aims to reduce thyroid hormone levels, which would typically lead to a cooler skin as the body's metabolic rate normalizes.

C) Weight loss - Methimazole treatment aims to reduce thyroid hormone levels, which would typically lead to potential weight gain as the body's metabolic rate normalizes.

D) Increased sleeping - Methimazole results in increased sleeping, as the client's metabolism slows down, leading to less energy and more fatigue.

A. Monitor the client for dysrhythmias- The significant decrease in potassium levels (hypokalemia) can predispose the client to cardiac dysrhythmias, so monitoring for any signs or symptoms of dysrhythmias is essential.
B. Advise the client to restrict potassium intake- With potassium levels already low (hypokalemia), restricting potassium intake further could exacerbate the deficiency. Instead, the client may need to increase their potassium intake through dietary changes or supplementation under healthcare provider guidance.
C. Advise the client to take the medication before bedtime- There's no medication mentioned in the scenario that requires a specific timing like before bedtime.
D. Check the client for orthostatic hypotension- The client reports dizziness and light- headedness upon standing, which are indicative of orthostatic hypotension. Checking for orthostatic hypotension involves measuring blood pressure and heart rate in different positions (lying, sitting, and standing) to assess for postural changes.
E. Advise the client to change positions slowly- Given the client's symptoms of dizziness and light-headedness upon standing, advising them to change positions slowly can help prevent falls or injuries associated with orthostatic hypotension.
