The patient received Humalog (rapid acting) insulin 5 units subcutaneously at 8:00 AM. The nurse plans to monitor this patient for signs of hypoglycemia at which time related to the insulin's peak action?

Choice A reason: Foot inspection is not an annual/yearly screening, but a daily self-care practice for people with diabetes. Foot inspection involves checking the feet for any signs of injury, infection, or ulceration, such as cuts, blisters, redness, swelling, or drainage. Foot inspection can help prevent or detect foot problems, such as neuropathy, ischemia, or infection, which can lead to amputation if left untreated. The nurse should teach Jo how to inspect his feet every day, and how to care for his feet, such as washing, drying, moisturizing, trimming nails, and wearing proper footwear.

Choice B reason: Serum creatinine (Cr) is an annual/yearly screening for people with diabetes. Serum creatinine is a blood test that measures the level of creatinine, a waste product that is filtered by the kidneys. Serum creatinine can indicate the kidney function, and detect kidney damage or disease, which is a common complication of diabetes. The nurse should explain to Jo that he needs to have his serum creatinine checked every year, and that he should keep his blood glucose and blood pressure under control, as these are the main risk factors for kidney problems.

Choice C reason: Chest X-ray is not an annual/yearly screening for people with diabetes, unless they have symptoms or risk factors for lung diseases, such as tuberculosis, pneumonia, or cancer. Chest X-ray is an imaging test that uses X-rays to produce pictures of the lungs and the chest cavity. Chest X-ray can help diagnose or monitor lung conditions, such as infections, inflammations, or tumors. The nurse should ask Jo about his history of smoking, exposure to environmental pollutants, or respiratory symptoms, such as cough, shortness of breath, or chest pain, and refer him to a doctor if he needs a chest X-ray.

Choice D reason: White blood cell count (WBC) is not an annual/yearly screening for people with diabetes, unless they have signs or risk factors for infections, such as fever, wounds, or immunosuppression. White blood cell count is a blood test that measures the number and types of white blood cells, which are the cells that fight infections and inflammation. White blood cell count can help diagnose or monitor infections, such as bacterial, viral, or fungal infections, or immune disorders, such as allergies, autoimmune diseases, or cancers. The nurse should assess Jo for any signs of infection, such as fever, chills, malaise, or pus, and advise him to seek medical attention if he has any.

Choice A reason: This statement is false. Glucose: 88 mg/dL is a normal blood sugar level and does not indicate any problem with fluid or electrolyte balance.

Choice B reason: This statement is false. WBCs: 4,000 is slightly below the normal range, but not significantly low. It may indicate a mild infection or inflammation, but not a serious fluid or electrolyte imbalance.

Choice C reason: This statement is false. K+: 3.4 mEq/L is slightly below the normal range, but not dangerously low. It may indicate a mild potassium deficiency, which can cause muscle weakness, but not restlessness or agitation.

Choice D reason: This statement is true. Na+: 154 mEq/L is above the normal range and indicates hypernatremia, or high blood sodium level. This can cause dehydration, confusion, restlessness, agitation, and seizures. It is a medical emergency that requires immediate treatment. Continuous tube feedings can increase the risk of hypernatremia if the formula is too concentrated or the fluid intake is inadequate.
