A nurse is preparing to administer amikacin 5 mg/kg IM every 8 hr to a client. The client weighs 70.8 kg. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. A 2-month-old infant: The DTaP vaccine series begins at 2 months of age according to the routine immunization schedule. Administering the first dose at this age provides early protection against diphtheria, tetanus, and pertussis, which can be severe in young infants. Subsequent doses are given at 4 months, 6 months, and booster doses at later intervals.

B. A 4-month-old infant: At 4 months, the infant is due for the second DTaP dose, not the initial dose. Administering the vaccine at this age without a prior first dose would be incomplete, as the series is designed to build immunity progressively from 2 months onward.

C. A 6-month-old infant: The 6-month visit typically coincides with the third DTaP dose in the primary series. The initial dose must have been administered at 2 months, making this age inappropriate for starting the series.

D. A 15-month-old toddler: By 15 months, the primary DTaP series should already be completed with a fourth dose administered between 15–18 months. Initiating the series at this age would require catch-up immunization protocols rather than the standard initial vaccination schedule.

A. Secure nonwashable items in a plastic bag for 7 days: While isolating nonwashable items can help reduce the risk of lice transmission, lice typically survive only 1–2 days off the scalp. Seven days is longer than necessary, making this measure less practical and not the primary recommendation for controlling pediculosis in the home.

B. Soak combs and brushes in a peroxide and water solution for 2 hr: Lice and nits can be effectively removed from combs and brushes using hot water rather than chemical solutions. Prolonged soaking in peroxide is unnecessary and may damage items without significantly improving decontamination.

C. Machine wash bed sheets in water greater than 54.4° C (130° F): Washing linens, clothing, and towels in hot water effectively kills lice and nits, preventing reinfestation. Heat is the most reliable method for decontaminating items that have been in contact with an infested individual, making this the recommended action.

D. Dry washed clothing and towels in a hot dryer for 10 min: While using a dryer can help, the duration and temperature must be sufficient to kill lice and nits. Ten minutes may be inadequate for thick items, and washing in hot water remains the primary and most effective preventive measure.
