A client exposed to tuberculosis is scheduled to begin prophylactic treatment with isoniazid. Which information is most important for the nurse to note before administering the initial dose?

Conversion of the client's PPD test from negative to positive

History of intravenous drug abuse

Current diagnosis of hepatitis B

Length of time of exposure to tuberculosis

Answer and Explanation

The Correct Answer is C

A. Conversion of the PPD test from negative to positive indicates exposure to tuberculosis but does not contraindicate the administration of isoniazid. It may actually indicate the need for prophylactic treatment.

B. A history of intravenous drug abuse is not directly related to the administration of isoniazid. However, it may be important for assessing risk factors for tuberculosis transmission and adherence to treatment.

C. Isoniazid can cause hepatotoxicity, so it is essential to assess for pre-existing liver conditions such as hepatitis B before administering the medication. Hepatitis B may increase the risk of liver damage associated with isoniazid.

D. The length of time of exposure to tuberculosis is important for assessing the risk of infection and determining the need for prophylactic treatment but does not impact the administration of isoniazid.

Correct Answer is B

Explanation

A. Flaky, peeling skin (desquamation) occurs in later stages of scarlet fever, typically after the rash begins to fade. It is not an early sign of the disease.
B. A red, sandpaper-like rash that typically begins on the chest and spreads outward is one of the earliest indications of scarlet fever. This rash is caused by exotoxins produced by Streptococcus pyogenes and is a hallmark sign of the illness.
C. A white coating on the tongue, often followed by a characteristic “strawberry tongue,” develops later in the progression of scarlet fever rather than as an early symptom.
D. While fever is a common symptom of streptococcal infections, it is not the earliest indicator of scarlet fever. The rash usually appears within 12 to 48 hours of fever onset, making it a more specific early sign.

Correct Answer is ["5.6"]

Explanation

Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg

Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml

1mg=1000mcg

Available dose = 1600000mcg/500ml Infusion rate:

1600000mcg=500ml 18000mcg=18000500/1600000

= 5.625 mL/hour

Rounded to the nearest tenth:5.6 ml/hour
