Hypomagnesemia

Hypocalcemia

Hyponatremia

Hypokalemia

Answer and Explanation

The Correct Answer is C

A.   Hypomagnesemia: While lithium can affect magnesium levels, starting a new exercise program is not typically associated with hypomagnesemia. Hypomagnesemia may result in muscle weakness, tremors, and cardiac dysrhythmias.
B.   Hypocalcemia: Starting a new exercise program is not typically associated with hypocalcemia. Hypocalcemia may present with muscle cramps, tetany, and seizures.
C. Hyponatremia: Starting a new exercise program may lead to dehydration and electrolyte imbalances, including hyponatremia (low sodium levels). This can have profound effects on patients taking lithium. Symptoms of hyponatremia include weakness, confusion, and seizures.

Correct Answer is B

Explanation

A. Warming the formula to room temperature would not address hyperkalemia.

B. Hyperkalemia can lead to cardiac dysrhythmias, so placing the client on a cardiac monitor

allows for continuous cardiac monitoring to detect any changes or abnormalities in heart rhythm.

C. Administering IV dextrose is not typically indicated for hyperkalemia. Instead, insulin may be administered with dextrose to promote cellular uptake of potassium.
D. Requesting a lactose-free formula is not relevant to the management of hyperkalemia.

A. "This medication can cause an increase in appetite." B. "You might experience hair loss while taking this medication." C. "This medication can cause diarrhea." D. "Urinary frequency is a common adverse effect of this medication." E. None F. None

Correct Answer is A

Explanation

A. "This medication can cause an increase in appetite." is correct. Amitriptyline is a tricyclic antidepressant (TCA) that commonly causes increased appetite and weight gain as side effects. Clients should be informed of this possibility and encouraged to monitor their diet and weight while taking the medication.

B. "You might experience hair loss while taking this medication." is incorrect. Hair loss is not a common adverse effect of amitriptyline. This side effect is more commonly associated with other medications, such as chemotherapy agents or certain anticonvulsants.

C. "This medication can cause diarrhea." is incorrect. Amitriptyline typically causes constipation rather than diarrhea due to its anticholinergic effects, which slow gastrointestinal motility. Clients should be advised to increase fiber and fluid intake to help manage constipation.

D.While trouble urinating can occur due to anticholinergic effects, urinary frequency is not a commonly reported adverse effect of amitriptyline.
