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 D
Explanation
A. The provider is not required to notify the client's employer about the admission to a mental health facility. This information is protected under confidentiality laws and regulations.
B. While the client may be strongly encouraged to take prescribed medications, they cannot be forced to do so without consent, especially if they are competent to make their own decisions.
C. Electroconvulsive therapy (ECT) typically requires informed consent from the patient or their legal representative, even in an involuntary admission scenario. Therefore, it is incorrect to state that ECT can be performed without consent.
D. If the client poses a risk of harm to themselves or others, the provider can prescribe restraints as a safety measure. This statement is correct and aligns with safety protocols in mental health facilities.
Correct Answer is D
Explanation
A. Administer an antitoxin: There is no specific antitoxin available for anthrax. Treatment primarily involves antibiotics and supportive care.
B. Quarantine the client: Quarantine may not be necessary unless the client is confirmed to have an active infection or poses a risk of spreading the disease to others.
C. Monitor the client for a productive cough: While respiratory symptoms can occur in inhalation anthrax, monitoring for a productive cough alone may not be sufficient for management.
D. Begin prophylactic treatment with ciprofloxacin: Prophylactic antibiotic treatment with ciprofloxacin or doxycycline is recommended following exposure to anthrax to prevent the development of the disease.
