1. A nurse is reinforcing teaching with a client about reducing dietary caffeine intake. The nurse should remind the client that 240 mL (8 oz) of which of the following beverages contains the least amount of caffeine?

ECT can cause temporary memory loss, particularly for events occurring around the time of the treatment. The client may experience difficulty remembering details of recent events or conversations. This effect is usually temporary and improves over time.

Neck pain is not a typical adverse reaction to ECT. The procedure itself does not involve manipulation or strain on the neck, and significant neck pain following ECT would be unusual. However, it is essential for the nurse to assess and address any discomfort or pain the client experiences after the procedure.

Voice alteration is not a known adverse reaction to ECT. ECT primarily affects the brain and does not directly impact the vocal cords or voice production.

Tingling of the scalp is not a common adverse reaction to ECT. During the procedure, the client receives a brief electrical stimulus, usually applied through electrodes placed on the scalp. Sensations experienced during the procedure are typically related to the electrical stimulation and are transient.

When collecting data from a child with pertussis (whooping cough), the nurse should expect the following manifestations:

1. Paroxysmal cough: The hallmark symptom of pertussis is a severe, uncontrollable cough that often occurs in bursts (paroxysms) followed by a characteristic "whooping" sound as the child inhales.
2. Posttussive vomiting: The coughing spells can be so severe that they may lead to vomiting.
3. Inspiratory whoop: As mentioned earlier, during the inhalation phase after a coughing episode, the child may make a distinctive whooping sound.
4. Cyanosis: The prolonged coughing episodes can sometimes cause the child's face to turn blue (cyanosis) due to inadequate oxygen intake.
5. Fatigue and exhaustion: The frequent and intense coughing episodes can be exhausting for the child, leading to fatigue and sleep disturbances.

Other possible manifestations of pertussis can include a mild fever, runny nose, and sneezing. However, these symptoms are less specific to pertussis and can be seen in other respiratory infections as well.

The manifestations listed in the question (beefy, red tongue; facial erythema; peeling of the hands and feet) are not typically associated with pertussis and may be indicative of other conditions or diseases. It is important to consult a healthcare provider for a proper evaluation and diagnosis.
