Heparin 7.,000 units is ordered. Heparin S.000 units per mL is available, How many milliliters (mL) should the nurse administer?

Choice A reason: 1:00 PM is not the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. Humalog is a rapid acting insulin that starts to work within 15 minutes, peaks in about an hour, and lasts for 2 to 4 hours. Therefore, the peak action of Humalog given at 8:00 AM would be around 9:00 AM, not 1:00 PM.

Choice B reason: 8:00 PM is also not the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. As explained in choice A, Humalog peaks in about an hour and lasts for 2 to 4 hours. Therefore, the effect of Humalog given at 8:00 AM would wear off by 12:00 PM, not 8:00 PM.

Choice C reason: There is no peak action for this insulin is an incorrect statement. Humalog does have a peak action, as described in choice A. The peak action of an insulin is the time when the insulin is most effective in lowering the blood glucose level. The peak action of an insulin can vary depending on the type, dose, and individual response of the patient.

Choice D reason: 9:00 AM is the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. Hypoglycemia is a condition of low blood glucose level, which can cause symptoms such as sweating, shaking, hunger, headache, dizziness, confusion, and loss of consciousness. Hypoglycemia can occur when the insulin dose is too high, the food intake is too low, or the physical activity is too high. The nurse should monitor the patient for signs of hypoglycemia around the peak action of the insulin, as this is when the blood glucose level is most likely to drop. The nurse should also teach the patient how to prevent, recognize, and treat hypoglycemia.

Choice A reason: This statement is true. Distended neck veins are a sign of fluid volume overload, as they indicate increased central venous pressure and right-sided heart failure.

Choice B reason: This statement is false. Hypotension is a sign of fluid volume deficit, not fluid volume overload. Hypotension occurs when the blood pressure is too low to perfuse the vital organs.

Choice C reason: This statement is false. Increased serum osmolality is a sign of fluid volume deficit, not fluid volume overload. Increased serum osmolality occurs when the blood concentration of solutes, such as sodium and glucose, is too high due to fluid loss.

Choice D reason: This statement is false. Dry oral mucosa is a sign of fluid volume deficit, not fluid volume overload. Dry oral mucosa occurs when the oral cavity is dehydrated due to fluid loss.

Choice E reason: This statement is true. Decreased urine specific gravity is a sign of fluid volume overload, as it indicates diluted urine and impaired kidney function.

Choice F reason: This statement is true. Weight gain is a sign of fluid volume overload, as it indicates fluid retention and edema.

Choice G reason: This statement is false. Sunken anterior fontanelle is a sign of fluid volume deficit, not fluid volume overload. Sunken anterior fontanelle occurs when the soft spot on the baby's head is depressed due to fluid loss.
