A nurse is reviewing the medical record for a child who is scheduled to receive a varicella immunization. Which of the following findings in the client's record should the nurse recognize as a contraindication?

Informed consent is a legal and ethical requirement for certain medical procedures. It involves providing the client with clear and comprehensive information about the procedure, including its risks, benefits, alternatives, and expected outcomes. The client must understand the information provided and voluntarily give their consent before the procedure can be performed.

Placement of a central venous catheter is an invasive procedure that carries risks and potential complications, making it necessary to obtain informed consent from the client.

Wound irrigation with an antibiotic solution is a standard nursing intervention for wound care and does not usually involve invasive procedures. Informed consent is not typically required for this procedure.

The administration of an iron injection using the Z-track technique is a standard nursing procedure. While it involves an injection, it is not typically considered an invasive procedure that would require informed consent.

Insertion of a nasogastric tube is a common procedure that involves passing a tube through the nose and into the stomach for various purposes, such as feeding, decompression, or medication administration. While it is an invasive procedure, it is often performed in emergency or critical care situations where the client's immediate well-being takes precedence. Informed consent may not be feasible or necessary in these situations, depending on the context and urgency.

Insulin lispro is a rapid-acting insulin, while insulin glargine is a long-acting insulin. It is important to keep them separate to maintain their individual properties and avoid any potential interactions or changes in their effectiveness.

Insulin glargine is a clear solution and should not appear cloudy. Cloudiness in insulin can indicate contamination or improper storage.

The instruction to "take an extra dose of insulin lispro prior to aerobic exercise" is not recommended. The client should consult with their healthcare provider to determine if any adjustments to their insulin regimen are necessary for exercise. Typically, adjustments are made based on the individual's blood glucose levels and anticipated intensity and duration of exercise. Insulin glargine is a long-acting insulin that provides a steady release of insulin over a prolonged period, without distinct peaks or valleys in its action. Its onset of action is gradual and its effect lasts for approximately 24 hours.

It is important for the client to receive accurate and appropriate instructions regarding their insulin regimen. The nurse should clarify any misunderstandings and provide accurate information to promote safe and effective diabetes management.
