A nurse is preparing to administer fluoxetine 40 mg PO daily.

The amount available is fluoxetine 20 mg/5mL.

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.).

Choice A rationale:

Altered body image is a hallmark feature of eating disorders. Individuals with eating disorders often have a distorted perception of their bodies, believing they are overweight or larger than they actually are. This distorted body image can lead to intense dissatisfaction with their appearance, even when they are underweight. They may engage in obsessive behaviors such as repeatedly checking their weight, measuring their body parts, and avoiding mirrors. They may also fixate on perceived flaws in their appearance, leading to significant distress and impairment in their daily lives.

Choice B rationale:

Amenorrhea, the absence of menstruation, is a common physiological consequence of eating disorders. It occurs due to hormonal imbalances caused by insufficient intake of calories and nutrients, particularly fat. The body requires a certain amount of body fat to maintain normal reproductive function. When body fat levels fall below a critical threshold, the hypothalamus, a part of the brain that regulates hormone production, signals the pituitary gland to reduce the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones play crucial roles in ovulation and menstruation. Without adequate levels of FSH and LH, ovulation and menstruation do not occur.

Choice C rationale:

Hyperactivity, characterized by excessive energy and restlessness, can manifest in individuals with eating disorders. This increased activity level may be a way to burn calories or compensate for perceived overeating. It may also be a way to distract themselves from thoughts about food and body image. The hyperactivity can present in various forms, such as excessive exercise, fidgeting, or constant movement.

Choice D rationale:

Bradycardia, a slower-than-normal heart rate, is another physiological sign that can accompany eating disorders. It occurs as the body attempts to conserve energy in response to inadequate caloric intake. The heart rate slows down to minimize energy expenditure. Bradycardia can have serious health implications, including fatigue, dizziness, fainting spells, and potentially life- threatening heart arrhythmias.

Choice E rationale:

Verbalized desire to gain weight is not a typical manifestation of eating disorders. Individuals with eating disorders often have a strong fear of weight gain and a persistent drive for thinness. They may actively resist efforts to increase their weight, even when they are dangerously underweight.

The correct answer is choice b. Administer the morning dose of lithium.

Choice A rationale:

Preparing for gastric lavage is unnecessary because a lithium level of 1.0 mEq/L is within the therapeutic range (0.6-1.2 mEq/L) and does not indicate toxicity.

Choice B rationale:

Administering the morning dose of lithium is appropriate as the current lithium level is within the therapeutic range, indicating that the medication is being managed correctly.

Choice C rationale:

Holding the medication and assessing for early manifestations of toxicity is not necessary since the lithium level is not indicative of toxicity. Toxicity typically occurs at levels above 1.5 mEq/L.

Choice D rationale:

Checking the client’s medication record to assess whether the client has been refusing her lithium is not relevant in this scenario because the lithium level is within the therapeutic range, suggesting compliance with the medication regimen.
