A nurse is performing an admission assessment on a client who had a recent positive pregnancy test. The first day of her last menstrual period (LMP) was May 8. According to Nägele's rule, which of the following dates should the nurse document as the client's estimated date of birth (EDB)?

A. Contact the facility's ethics committee: This is incorrect because it is not an urgent action and it does not address the client's immediate needs. The ethics committee can be consulted later if there are ethical dilemmas or conflicts regarding the client's care.

B. Obtain consent from the client's employer: This is incorrect because it is not a valid source of consent. The employer has no legal or ethical authority to make decisions for the client, unless they are also a designated surrogate or proxy.

C. Limit care to comfort measures: This is incorrect because it does not meet the standard of care for an emergency situation. The nurse has a duty to provide life-saving interventions for a client who is unconscious and requires emergency medical procedures, unless there is evidence of a valid advance directive that states otherwise.

D. Proceed with provision of medical care: This is correct because it follows the principle of implied consent, which assumes that a reasonable person would consent to emergency treatment if they were able to do so. The nurse should document the circumstances and continue to search for family members or other sources of consent.

A. Flexing the client's neck forward can increase intracranial pressure by impeding venous drainage from the brain and increasing cerebral blood volume. Therefore, this choice is incorrect.

B. Grouping several nursing activities to be completed at one time can increase intracranial pressure by stimulating the client and causing fluctuations in blood pressure and heart rate. Therefore, this choice is incorrect.

C. Limiting suctioning the client's airway to 30 seconds at a time can reduce intracranial pressure by minimizing hypoxia and hypercarbia, which can cause cerebral vasodilation and increased cerebral blood volume. However, this intervention alone is not sufficient to prevent increased intracranial pressure, and suctioning should be done only when necessary and with caution. Therefore, this choice is partially correct but not the best answer.

D. Placing the client in a quiet environment can reduce intracranial pressure by minimizing sensory stimulation and promoting relaxation, which can lower blood pressure and heart rate and decrease cerebral metabolic demand. Therefore, this choice is correct and the best answer.
