A nurse is monitoring a client's IV site. The nurse should report which of the following findings as manifestations of phlebitis? (Select all that apply.)

B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.

A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.

C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.

D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.

D. Persistent headache can occur with elevated levels of gentamicin, as it may indicate neurotoxicity. Gentamicin can cause neurotoxic effects, including headaches, especially when levels are elevated.

E. Tinnitus (ringing in the ears) is a classic symptom of gentamicin toxicity. Elevated gentamicin levels can lead to ototoxicity, which manifests as tinnitus among other auditory symptoms.

A. Insomnia is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause insomnia.

B. Constipation is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause constipation.

C. Xerostomia (dry mouth) is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause xerostomia.
