Lorraine who is on chemotherapy has a history of cardiac disease. The client is at risk for cardiac complications because:

Correct Answer: B

Rationale: Chemotherapy can cause anemia, which reduces the oxygen-carrying capacity of the blood due to decreased red blood cells or hemoglobin. For a patient with a history of cardiac disease, this is particularly concerning because the heart must work harder to deliver oxygen to tissues, potentially exacerbating cardiac conditions. Reduced white blood cells increase infection risk, but this does not directly affect cardiac function. Sodium levels and hematocrit are not the primary concerns in this context. Therefore, reduced oxygen-carrying capacity is the correct answer.

Correct Answer: B

Rationale: Intravesical administration involves the direct instillation of medication into the bladder, which is a common method for treating superficial bladder cancer. This approach allows high concentrations of the drug, such as mitomycin, to come into direct contact with the cancerous cells lining the bladder, minimizing systemic side effects. Intraventricular and intrathecal administrations are used for delivering drugs to the brain and spinal cord, respectively, while intravascular administration refers to intravenous delivery. Intravesical administration is specifically designed for bladder conditions, making it the correct answer.

Correct Answer: A

Rationale: A. Limit fluid intake to prevent fluid overload: Antilipemic drugs can sometimes cause fluid retention, so it is important for the patient to limit fluid intake to prevent fluid overload.

Correct Answer: A

Rationale: While Propranolol is commonly used to treat conditions such as hypertension and certain heart-related issues, it is also used off-label for the treatment of post-traumatic stress disorder (PTSD). Propranolol has shown efficacy in reducing the intensity of emotional memories and symptoms associated with PTSD by blocking the effects of stress hormones. It is believed to help alleviate symptoms such as anxiety and hyperarousal in individuals with PTSD. However, it is important to note that the off-label use of Propranolol for PTSD should only be done under the guidance and supervision of a healthcare professional.

Correct Answer: C

Rationale: Nitrous oxide has a high minimum alveolar concentration (MAC >100%), not low, due to low potency, so that's false. Halogenated agents (e.g., isoflurane) have higher brain:blood coefficients, reflecting solubility, making that false. They reduce mean arterial pressure (MAP) proportional to alveolar concentration via vasodilation, a true statement. Nitrous oxide does decrease tidal volume and increase respiratory rate, true. They don't reduce cerebral metabolic rate via blood flow alone but directly. MAP reduction is a key hemodynamic effect, guiding anesthetic depth monitoring.
