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. Turn the overhead lights on while giving instructions. B. Stand behind the client to avoid intimidation. C. Provide handouts written at a 12th grade reading level. D. Use background music to promote relaxation.

Correct Answer is A

Explanation

A. Turning on overhead lights ensures that the client can see the instructions clearly, which is particularly important for older adults who may have visual impairments. Adequate lighting helps improve comprehension and reduces the risk of misunderstandings.
B. Standing behind the client may cause confusion or discomfort. It is better to face the client while communicating.
C. Handouts should be written at a lower reading level, typically around the 5th to 6th grade, to ensure that most clients can understand them, especially older adults.
D. Background music may be distracting rather than helpful during the provision of important instructions.
