A nurse is collecting a medication history from the parent of a preschooler who comes to the clinic for routine immunizations. For which of the following findings should the nurse withhold the varicella immunization?

A pregnant parent

Receiving treatment for leukemia

Taking acetaminophen for mild discomfort

An allergy to eggs

Answer and Explanation

The Correct Answer is B

A. A pregnant parent. A child can receive the varicella vaccine even if the parent is pregnant. While the varicella vaccine is a live attenuated vaccine, the vaccinated child does not pose a significant risk of transmission to others. The parent should avoid direct contact with the vaccinee's rash if one develops, but this is not a contraindication to immunization.

B. Receiving treatment for leukemia. Children undergoing treatment for leukemia often have weakened immune systems due to chemotherapy or radiation. The varicella vaccine is a live attenuated vaccine, meaning it contains a weakened form of the virus that could cause severe illness in immunocompromised individuals. These children should not receive live vaccines until their immune function improves and their healthcare provider approves vaccination.

C. Taking acetaminophen for mild discomfort. Acetaminophen is an over-the-counter pain reliever and fever reducer that does not interfere with the efficacy or safety of the varicella vaccine. There is no evidence that mild analgesic use before or after vaccination affects immune response, so it is not a reason to withhold the immunization.

D. An allergy to eggs. Unlike some influenza and yellow fever vaccines, the varicella vaccine is not produced using egg-based components. An egg allergy is not a contraindication to receiving the varicella vaccine, as it does not contain egg proteins.

Correct Answer is ["1"]

Explanation

Convert pounds to kilograms:

Conversion factor: 1 kg = 2.2 lb

=145 lb / 2.2 lb/kg

= 65.9 kg

Calculate the total daily dose:

Total daily dose (mg) = Weight (kg) × Dosage (mg/kg/day)

= 65.9 kg 3 mg/kg/day

= 197.7 mg/day

Calculate the dose per administration (divided into two doses):

Dose per administration (mg) = Total daily dose (mg) / Number of doses

=197.7 mg/day / 2 doses

= 98.85 mg/dose

Calculate the number of tablets per dose:

Number of tablets = Desired dose (mg) / Available dose (mg/tablet)

=98.85 mg/dose / 100 mg/tablet

= 0.9885 tablets

Round to the nearest whole number:

0.9885 tablets is 1 tablet

A. Cover the administration area with plastic wrap. B. Massage the ointment into the skin. C. Spread the ointment in a 10 cm2 (4in2) area. D. Apply the ointment in a thick layer.

Correct Answer is A

Explanation

A. Cover the administration area with plastic wrap. After applying nitroglycerin ointment, the area should be covered with plastic wrap or a transparent dressing to prevent evaporation and ensure proper absorption through the skin. This also helps prevent the medication from accidentally transferring to another person or clothing.

B. Massage the ointment into the skin. Nitroglycerin ointment should not be massaged into the skin, as this can cause rapid absorption and lead to hypotension and dizziness due to vasodilation. Instead, it should be applied as a thin, even layer and covered with a dressing.

C. Spread the ointment in a 10 cm² (4 in²) area. The correct application method involves measuring the exact prescribed amount (e.g., using the applicator paper) and applying it in a thin layer. The area of application may vary based on the dosage, but the focus should be on accurate measurement, not a specific area size.

D. Apply the ointment in a thick layer. A thick application is unnecessary and could increase absorption too quickly, leading to side effects such as headache, dizziness, and hypotension. Instead, a measured dose should be spread thinly and evenly onto clean, dry skin.
