A nurse is reinforcing teaching with a client who is postpartum about the measles, mumps, andrubella (MMR) vaccine.

Which of the following instructions should the nurse include in the teaching?

When a central venous catheter (CVC) is inserted, it is essential to confirm proper catheter placement to ensure safe and effective administration of TPN and other medications. A chest x-ray is the gold standard method to verify the correct positioning of the CVC tip. It helps determine if the catheter is appropriately positioned in the superior vena cava or another desired location, which minimizes the risk of complications such as pneumothorax or improper medication delivery.

The other options listed are not appropriate actions for the nurse to take in this situation:

1. Verifying the amount of TPN solution the client is receiving every 4 hours is a task related to ongoing monitoring of TPN administration, but it is not directly related to the preparation of the client for CVC insertion.
2. Using clean technique when changing the catheter dressing is not appropriate for CVC insertion. Sterile technique is required during the insertion of a CVC to minimize the risk of infection.
3. Placing the client in Sims' position is not the appropriate position for CVC insertion. The client is typically placed in a supine or Trendelenburg position during the procedure to facilitate access to the central venous system.

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.
