A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL How many mL should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Increase hematocrit: Fluid overload typically leads to hemodilution, resulting in a decrease in hematocrit rather than an increase. Therefore, an increase in hematocrit would not be expected in a client with fluid overload.
B. Increased temperature: Fluid overload is not typically associated with an increased body temperature. Instead, fever may indicate an infection or another underlying cause. Therefore, an increased temperature would not be a typical finding in a client with fluid overload.
C. Increased heart rate: Fluid overload can lead to an increased heart rate as the body attempts to maintain adequate cardiac output in the presence of excess fluid volume. An elevated heart rate is a compensatory mechanism to maintain tissue perfusion despite the increased workload on the heart.
D. Increased respiratory rate: Fluid overload can cause pulmonary congestion, leading to increased respiratory effort and a higher respiratory rate as the body attempts to compensate for decreased gas exchange efficiency. An increased respiratory rate helps to improve oxygenation and remove excess carbon dioxide from the body.
E. Increased blood pressure: Fluid overload often leads to increased blood pressure due to the increased volume of circulating blood, which can strain the cardiovascular system. Elevated blood pressure is a common manifestation of fluid overload and reflects the increased workload on the heart and blood vessels.

A. Intermittent abdominal pain following passage of bloody mucus: This description is more consistent with the symptoms of placental abruption, where there is painful bleeding with the passage of blood and mucus. Placenta previa typically presents with painless bleeding.
B. Increasing abdominal pain with a non-relaxed uterus: Increasing abdominal pain with a non-relaxed uterus suggests uterine irritability, which may be indicative of preterm labor rather than placenta previa. Placenta previa typically presents with painless bleeding.
C. Painless red vaginal bleeding: This finding is characteristic of placenta previa. Pain is typically absent or minimal with placenta previa, and the bleeding is bright red due to the richly oxygenated maternal blood flowing from the placental vessels.
D. Abdominal pain with scant red vaginal bleeding: While abdominal pain may occur in some cases of placenta previa, it is typically not the predominant symptom. Additionally, the bleeding associated with placenta previa is typically painless and can be more profuse than scant bleeding.
