A nurse is preparing to administer cefadroxil oral suspension 15 mg/kg PO to a client who weighs 98 lb. Available is cefadroxil 250 mg/5 mL. Which of the following actions should the nurse take first?
Round the amount to be administered to the nearest whole number.
Calculate the dosage in milligrams.
Calculate the dosage in milliliters.
Convert the client's weight to kilograms.
The Correct Answer is D
Choice A rationale:
Rounding the amount to be administered to the nearest whole number is a step that may be necessary, but it should not be the first action taken. The nurse should first ensure that the dosage calculation is accurate and based on the client's weight in kilograms. Once the dosage in milligrams is calculated, rounding can be considered.
Choice B rationale:
Calculating the dosage in milligrams is an essential step, but it is not the first action the nurse should take. To determine the correct dosage in milligrams, the nurse needs to convert the client's weight from pounds to kilograms first, as the medication order is given in milligrams per kilogram.
Choice C rationale:
Calculating the dosage in milliliters is not the first action to take because the medication is available in milligrams, and the order is based on weight in kilograms. Converting the weight to kilograms is the initial step to ensure that the dose is calculated correctly.
Choice D rationale:
Converting the client's weight to kilograms is the first and most crucial step in this dosage calculation. The medication order is given in milligrams per kilogram, and the client's weight is provided in pounds. To ensure accurate dosing, the nurse must convert the weight to kilograms, as this is the foundation for calculating the correct dosage in milligrams.

Correct Answer is A
Explanation
This question evaluates communication adaptations for clients experiencing hearing impairment. The nurse must apply therapeutic communication principles that maximize auditory perception and minimize environmental interference. Knowledge of sensory deficits, lip-reading facilitation, sound discrimination, and appropriate assistive communication strategies is required to identify the safest intervention.
Choice A rationale: Reducing competing environmental sounds improves speech discrimination and auditory processing in hearing-impaired clients. Background noise interferes with interpretation of consonants and speech frequencies. Quiet environments enhance comprehension, decrease communication fatigue, and promote accurate understanding of discharge instructions and healthcare information.
Choice B rationale: Braille communication assists clients with severe visual impairment, not hearing impairment. Hearing loss primarily affects auditory sensory pathways involving cochlear hair cells or auditory nerve transmission. Providing Braille would not improve comprehension unless the client additionally has blindness or significant visual disability.
Choice C rationale: Standing directly beside the client limits visibility of facial expressions and lip movements essential for speech interpretation. Effective communication with hearing-impaired individuals requires face-to-face positioning, adequate lighting, and clear articulation to support residual hearing and visual speech cues simultaneously.
Choice D rationale: Repeating misunderstood phrases identically often fails because the original wording remains difficult to discriminate acoustically. Rephrasing sentences with different vocabulary improves semantic processing and contextual interpretation. Therapeutic communication emphasizes clarification rather than repetitive unchanged verbalization during hearing-related misunderstandings.
Correct Answer is B
Explanation
Answer and explanation
The correct answer is choice B.
Choice A rationale:
Yoga involves gentle stretching and may not directly impact the phlebitis.
Choice B rationale:
Therapeutic massage could potentially dislodge a clot in the leg, leading to a dangerous condition called a pulmonary embolism.
Choice C rationale:
Acupressure, like yoga, involves gentle pressure and may not directly impact the phlebitis.
Choice D rationale:
Acupuncture involves the insertion of needles and could potentially cause harm, but it is less likely to dislodge a clot than massage.
