When learning to use an insulin pen, a client with diabetes dials 28 units of regular insulin instead of 24 units, the prescribed dose. Which action should the nurse take?

Discard the incorrectly dialed dose and recalibrate the insulin pen.

Save the dialed dose and prepare the correct dose using a syringe

Assist the client to administer 24 units of the dialed dose, and waste the remainder.

Advise the client to dial down to the correct dose, which can then be administered.

Answer and Explanation

The Correct Answer is A

A.   Administering an incorrect dose of insulin can lead to hypoglycemia, a serious complication. Discarding the incorrectly dialed dose ensures patient safety. Directly addresses the error and prevents potential harm.
B.   This option is inefficient and increases the risk of error. It's unnecessary to use both a pen and a syringe for a single dose. Does not address the immediate issue of the incorrect dose.
C.   Administering more insulin than prescribed is dangerous and can lead to hypoglycemia. Wasting the remainder doesn't address the core issue of the incorrect dose. Increases the risk of hypoglycemia.
D.   Insulin pens are designed to be precise. Dialing down to the correct dose after an error can compromise the accuracy of the dose. Does not ensure accurate dosing.

Correct Answer is B

Explanation

A. Hematocrit measures the proportion of blood volume that is occupied by red blood cells. A hematocrit of 33% is lower than the normal range (42% to 52% for males and 37% to 47% for females). While this indicates anemia and reduced oxygen-carrying capacity of the blood, it is not directly related to the risk for infection.
B. White blood cells (WBCs) are crucial for the immune system and fighting infections. A WBC count of 1,500/mm³ is significantly below the normal range (5,000 to 10,000/mm³). This low WBC count, also known as leukopenia, indicates a decreased ability to fight infections, making the client highly susceptible to infections.
C. Hemoglobin measures the oxygen-carrying capacity of red blood cells. A hemoglobin level of 10 g/dL is below the normal range (14 to 18 g/dL), indicating anemia. While anemia affects overall health and can contribute to fatigue and weakness, it does not directly indicate the risk for infection.
D. The red blood cell (RBC) count measures the number of red blood cells in the blood. A count of 3.5 x 10^12/L is below the normal range (4.2 to 5.4 x 10^12/L), indicating a reduction in red blood cells and anemia. Like low hemoglobin, this value indicates anemia but does not directly reflect the risk for infection.

A. Report reoccurring visual signs of retinal detachment. B. Maintain the head in one postoperative position. C. Watch for signs of infection in the surgical eye. D. Ambulate to the bathroom with assistance.

Correct Answer is A

Explanation

A. This is the most crucial information to provide. A scleral buckling procedure is performed to repair a retinal detachment. Any signs of detachment recurrence are critical and should be reported immediately. Directly addresses the primary goal of the surgery.
B. While maintaining the head in a specific position is often recommended post-surgery, it's not the most critical information in this context. The focus should be on identifying potential complications. Not as critical as the other options.
C. Infection is a potential complication of any surgery, but it's not the primary concern immediately post-scleral buckling. Important but not the most critical information.
D. Ambulation is generally encouraged to prevent complications like pneumonia and deep vein thrombosis, but it's not a specific concern immediately post-scleral buckling. Not directly related to the procedure.
