A nurse is caring for a client who has a magnesium level of 2.7 mEq/L. Which of the following interventions should the nurse plan to take?
Initiate continuous cardiac monitoring.
Administer 40 mEq/L potassium chloride PO with orange juice.
Provide a diet rich in legumes, nuts, and green vegetables.
Monitor the client for tetany.
The Correct Answer is A
- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.
- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.
- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.
- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs

Correct Answer is B
Explanation
- A is incorrect because diarrhea is not an adverse effect of clonidine, but rather a symptom of other conditions such as infection, inflammation, or food intolerance.
 - B is correct because dry mouth is a common adverse effect of clonidine, which is an alpha-2 adrenergic agonist that reduces sympathetic nervous system activity.
 - C is incorrect because photophobia, or sensitivity to light, is not an adverse effect of clonidine, but rather a symptom of other conditions such as migraine, eye injury, or infection.
 - D is incorrect because bruising, or bleeding under the skin, is not an adverse effect of clonidine, but rather a symptom of other conditions such as coagulation disorders, vitamin deficiency, or trauma.
 
Correct Answer is ["13"]
Explanation
gtt/min = (mL/hr x gtt/mL) / 60
gtt/min = (50 x 15) / 60 gtt/min = 750 / 60 gtt/min = 12.5 Rounding to the nearest whole number, the answer is 13.
Therefore, the nurse should set the manual IV infusion to deliver 13 gtt/min.
