Heparin 7.,000 units is ordered. Heparin S.000 units per mL is available, How many milliliters (mL) should the nurse administer?
(Do not round)
The Correct Answer is ["1.4"]
The nurse should administer 1.4 mL of Heparin to the patient.
To calculate the number of milliliters (mL) the nurse should administer, we can use the following steps:
Step 1: Calculate the total amount of Heparin available in mL
Heparin concentration: 5,000 units per mL
Ordered Heparin dose: 7,000 units
Total mL of Heparin needed = Ordered dose / Heparin concentration
Total mL = 7,000 units / 5,000 units per mL = 1.4 mL

Correct Answer is D
Explanation
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.
Correct Answer is B
Explanation
Choice A reason: This statement is false. Drinking more fluids in the late evening can cause nocturia, which is the need to urinate frequently at night. This can disrupt the sleep cycle and increase the risk of falls.
Choice B reason: This statement is true. Dry mouth is a sign of dehydration and indicates the need for more fluid intake. Older adults may have reduced thirst sensation and may not drink enough fluids throughout the day.
Choice C reason: This statement is false. Caffeine is a diuretic, which means it increases urine output and can worsen dehydration. Confusion is a symptom of dehydration and requires immediate medical attention.
Choice D reason: This statement is false. Feeling full is not a reliable indicator of hydration status. Older adults may have decreased appetite and gastric motility, which can make them feel full even when they are dehydrated.
