A nurse is preparing to administer 50 mcg of fentanyl to a client who is in labor. The amount available is 100 mcg per 2 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Seizure disorder: A seizure disorder does not directly affect the use of metformin. While some medications used to manage seizures may have interactions, metformin itself is not contraindicated in clients with a history of seizures, and it can generally be used safely with proper monitoring.

B. Renal insufficiency: Metformin is contraindicated in clients with renal insufficiency because impaired kidney function can lead to accumulation of the drug, increasing the risk of lactic acidosis, a rare but potentially life-threatening complication. Baseline and ongoing assessment of renal function, such as serum creatinine and estimated glomerular filtration rate (eGFR), is essential before starting therapy.

C. Polycystic ovary syndrome: Metformin is actually commonly used in clients with polycystic ovary syndrome to improve insulin sensitivity and support ovulation. This condition is not a contraindication, and metformin may provide therapeutic benefits beyond glucose control.

D. Gluten intolerance: Gluten intolerance has no impact on metformin use. Metformin does not contain gluten and does not interfere with gluten-related conditions, so it can be safely prescribed in clients with gluten intolerance.

A. Denial: Denial is an expected initial stage of grief in response to terminal illness. Clients may have difficulty accepting the diagnosis and may refuse to believe the reality of their condition as a coping mechanism.

B. Reorganization: Reorganization is a later stage of grief associated with adapting to loss after bereavement. It is not typically part of the immediate response to a terminal diagnosis in the dying process.

C. Numbing: Numbing is more commonly associated with acute grief reactions following sudden loss, rather than the anticipatory grief experienced after a terminal diagnosis.

D. Reinvesting: Reinvesting refers to redirecting emotional energy into new relationships or activities after loss. This stage occurs after bereavement and is not part of the expected stages of grief during the dying process.
