A nurse is assessing a client who has a magnesium level of 4.4 mEq/L. Which of the following findings should the nurse expect?
Hypotension
Tachycardia
Muscle cramps
Hyperreflexia
None
None
The Correct Answer is A
A. Hypotension occurs because hypermagnesemia causes vasodilation, which lowers blood pressure. Magnesium acts as a smooth muscle relaxant, decreasing vascular resistance and contributing to hypotension. This is a common clinical finding when magnesium levels exceed the normal range.
B. Tachycardia is not expected with hypermagnesemia. Elevated magnesium levels depress the heart's electrical activity, leading to bradycardia (slow heart rate) instead of tachycardia.
C. Muscle cramps are typically associated with hypomagnesemia, which increases neuromuscular excitability. In hypermagnesemia, neuromuscular function is suppressed, leading to muscle weakness rather than cramps.
D. Hyperreflexia is a symptom of hypomagnesemia, not hypermagnesemia. In hypermagnesemia, neuromuscular activity is depressed, resulting in diminished or absent deep tendon reflexes

Correct Answer is C
Explanation
A. "Limit your meals to three times per day." - Incorrect. Following gastric bypass surgery,
clients are typically advised to eat small, frequent meals rather than limiting to three large meals per day.
B. "Consume at least 25 grams of fiber daily." - Incorrect. While fiber is important for gastrointestinal health, clients following gastric bypass surgery may need to avoid high-fiber foods initially and gradually reintroduce them based on individual tolerance.
C. "Start each meal with a protein source." - Correct. Protein is essential for wound healing and maintenance of muscle mass after gastric bypass surgery. Starting each meal with a protein source helps ensure an adequate intake.
D. "Check your blood glucose level before each meal." - This instruction is not directly related to dietary management following gastric bypass surgery. Blood glucose monitoring may be necessary for clients with diabetes, but it is not specific to post-gastric bypass dietary
instructions.
Correct Answer is C
Explanation
A. Encourage the client to ambulate in the hallway 1 hr before bedtime - While light exercise during the day can promote better sleep, exercising close to bedtime can actually disrupt sleep.
B. Tell the client to avoid drinking fluids 1 hr before bedtime - While limiting fluids close to bedtime can reduce nighttime awakenings to urinate, it may not directly address difficulty falling asleep.
C. Schedule routine care tasks during hours when the client is awake - This action ensures that the client can maximize restful sleep during the night by minimizing disruptions from care
activities.
D. Advise the client to leave the television in the room on when trying to fall asleep - Screen
time before bed can interfere with falling asleep due to the stimulating effect of light and content.
