A nurse is reinforcing teaching with a 36-year-old client who is at 16 weeks of gestation and is scheduled for an amniocentesis. The nurse should include in the teaching that an amniocentesis is performed to identify which of the following findings?

Rationale:

A. Beefy, red tongue: A beefy, red tongue is typically associated with scarlet fever, not pertussis. It results from the streptococcal infection and accompanying inflammatory response, which is unrelated to the bacterial cause and symptom pattern of pertussis.

B. Productive cough with thick mucous: Pertussis, or whooping cough, usually causes a paroxysmal, dry, hacking cough followed by a characteristic "whooping" sound on inspiration. It is not commonly associated with a productive cough containing thick mucus, especially in early and peak stages.

C. Facial erythema: Facial erythema can occur during severe coughing fits in children with pertussis due to the forceful and prolonged nature of coughing episodes. The increased intrathoracic pressure during coughing may lead to flushing or redness of the face.

D. Koplik spots: Koplik spots are small, bluish-white lesions on the buccal mucosa and are an early sign of measles, not pertussis. They are not present in bacterial infections like Bordetella pertussis, which affects the respiratory tract.

Rationale:

A. Withhold the medication until the provider signs the prescription: Waiting for the provider's signature before administering a telephone order may delay critical care. Verbal or telephone orders can be acted upon immediately if clearly understood, documented, and later signed by the provider within the facility’s required timeframe.

B. Record the date and time of the telephone prescription: Accurate documentation includes noting the date and time the telephone order was received. This ensures clarity, legal compliance, and proper sequencing of medical events in the client's record.

C. Request that the provider confirm the read-back of the prescription: A read-back process reduces the risk of medication errors by confirming that the nurse correctly heard and understood the provider’s order. It is a Joint Commission-recommended safety practice.

D. Ask the provider to spell out the name of the medication: Asking the provider to spell out high-risk or sound-alike medications helps avoid transcription errors. This step is especially important when communication clarity is compromised over the phone.

E. Instruct another nurse to record the prescription in the medical record: The nurse receiving the order is responsible for documenting it. Delegating this task to another nurse increases the chance of miscommunication and errors, and violates proper protocol.
