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 A
Explanation
A.
A. Changing clothes after working in the field helps prevent pesticide residue from being transferred to other surfaces and reduces the risk of exposure to pesticides.
B. Applying petroleum jelly to the nostrils is not an effective method for minimizing exposure to pesticides and may not provide significant protection.
C. Wiping fruits and vegetables with a dry cloth may remove some surface dirt but is unlikely to effectively remove pesticide residues, especially if they have been absorbed into the produce.
D. Taking a hot shower after finishing work may help remove pesticide residues from the skin but does not address the potential for exposure from contaminated clothing or other surfaces.
Correct Answer is B
Explanation
A. The examination light of the ophthalmoscope should be directed toward the client's eye, not the client's face.
B. When examining the left eye, the nurse should stand on the right side of the client to facilitate proper alignment of the ophthalmoscope with the client's eye.
C. Dimming the lights in the room may improve visualization of the client's internal eye
structures, but it is not typically necessary for ophthalmoscopic examination and may hinder the nurse's ability to assess the client effectively.
D. Placing the ophthalmoscope directly against the client's forehead would not facilitate proper examination of the internal eye structures and may cause discomfort to the client.
