In checking the dose of intravenous ticarcillin disodium prescribed for an older client, the nurse notes that the 24 hour dosage is lower than the normal range. Which finding supports the need for this reduced dosage?

Reference range

Creatinine [0.6 to 1.2 mg/dL (53 to 106 μmol/L)]

White blood cells (WBC) [5,000 to 10,000/mm3 (5 to 10 x 109/L)]

White blood cell count of 8,000/mm3 (8 X 109/L).

Inelastic skin turgor.

Serum creatinine of 3.5 mg/dL (310 μmol/L).

Thin, fragile hand and arm veins.

Answer and Explanation

The Correct Answer is C

A. A white blood cell count of 8,000/mm³ is within the normal range and does not indicate a need for dosage adjustment.
B. Inelastic skin turgor may indicate dehydration or aging but does not directly affect drug dosage.
C. Elevated serum creatinine levels indicate impaired renal function, which necessitates a reduced dosage of medications excreted through the kidneys, such as ticarcillin disodium.
D. Thin, fragile veins are a concern for intravenous access but do not affect the medication dosage.

Correct Answer is C

Explanation

A. Palpating muscle tone is important but should be done in conjunction with resistance testing to assess strength.

B. Asking the client to close his eyes is not necessary for assessing muscle strength.

C. Applying resistance while the client extends and flexes his arms helps evaluate the muscle strength and function accurately.

D. Providing an object to hold is not relevant for assessing muscle strength in this context.

A. "Antibiotics cause significant fluctuations in blood glucose, which are controlled with insulin." B. "The infection and the steroid medications you are taking can increase your blood sugar." C. "You may need to take insulin when you go home since your oral agent is no longer sufficient." D. "The use of insulin is easier to control your blood sugars while you are hospitalized."

Correct Answer is B

Explanation

A. While antibiotics can influence blood glucose, the primary reason for insulin in this context is the effect of steroids and infection on blood glucose levels.
B. Methylprednisolone, a steroid, can increase blood glucose levels, necessitating the use of insulin to manage elevated glucose levels during illness.
C. The need for insulin is related to the current hospitalization and medication effects, not necessarily a long-term change in diabetes management.
D. The ease of control is less relevant compared to the fact that steroids and infection can significantly impact blood glucose levels, necessitating insulin during hospitalization.
