The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag is contains magnesium sulfate 4 grams in dextrose 5% in water (DW) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

A. When signs of severe hypoglycemia occur:
Glucagon is used to rapidly increase blood glucose levels in cases of severe hypoglycemia when the person is unable to eat or drink. It is administered in emergency situations where the individual is unconscious or unable to consume oral glucose.

B. Before meals to prevent hyperglycemia:
Glucagon is not used to prevent hyperglycemia or as a routine preventive measure. It is specifically for emergency treatment of severe hypoglycemia.

C. When unable to eat during sick days:
While glucagon can be used if the person is unable to eat due to severe hypoglycemia, it is not typically used as a preventative measure for situations where the client is simply unable to eat. Regular monitoring and management of blood glucose levels are necessary during illness.

D. At the onset of signs of diabetic ketoacidosis:
Glucagon is not used to treat diabetic ketoacidosis (DKA). DKA is managed with insulin, fluids, and electrolytes, not glucagon.

A) Use the cream only on intact skin: This is correct advice as applying betamethasone cream to broken or infected skin can exacerbate the condition or lead to systemic absorption and side effects. Ensuring the cream is applied only to intact skin helps prevent complications.

B) Apply the cream to the area for 2 weeks: This instruction is appropriate depending on the severity of the eczema and the prescribing healthcare provider’s guidance. Typically, topical corticosteroids like betamethasone are used for a prescribed duration, often not exceeding 2 weeks to avoid potential side effects.

C) Cover the site with an occlusive dressing: This indicates a need for further teaching. Occlusive dressings are generally not recommended with topical corticosteroids unless specifically instructed by a healthcare provider. They can increase the absorption of the medication, potentially leading to more side effects, such as thinning of the skin.

D) Limit exposure to direct sunlight: This is good advice because corticosteroids can increase skin sensitivity to sunlight, leading to potential sunburn or other skin issues. Clients should be advised to protect their skin from excessive sun exposure while using such medications.
