A nurse is teaching a group of clients about St. John's wort.
Which of the following pieces of information should the nurse include in the teaching?

"St. John's wort can be used to treat severe depression."

"St. John's wort can lower prostate-specific antigen levels."

"St. John's wort increases estrogen levels in the body."

"St. John's wort can reduce the effectiveness of oral contraceptives.".

Answer and Explanation

The Correct Answer is D

The correct answer is choice d. “St. John’s wort can reduce the effectiveness of oral contraceptives.”

Choice A rationale:

St. John’s wort is commonly used to treat mild to moderate depression. It has been shown to be effective in alleviating symptoms of depression, likely due to its impact on neurotransmitters like serotonin.

Choice B rationale:

There is no evidence to suggest that St. John’s wort can lower prostate-specific antigen (PSA) levels. PSA levels are typically monitored for prostate health, and St. John’s wort does not have an impact on these levels.

Choice C rationale:

St. John’s wort does not increase estrogen levels in the body. It primarily affects neurotransmitters and has no known effect on hormone levels.

Choice D rationale:

St. John’s wort can indeed reduce the effectiveness of oral contraceptives. It induces certain liver enzymes that can increase the metabolism of contraceptive hormones, thereby reducing their effectiveness and increasing the risk of unintended pregnancy.

Correct Answer is ["10"]

Explanation

To calculate the amount of fluoxetine to administer, we can use the following steps:

Step 1: Identify the desired dose, which is 40 mg.

Step 2: Identify the available dose, which is 20 mg/5 mL.

Step 3: Set up the equation to solve for the unknown, which is the volume in mL. The equation is (Desired Dose ÷ Available Dose) × Volume = Volume to Administer.

Step 4: Substitute the known values into the equation: (40 mg ÷ 20 mg) × 5 mL = Volume to Administer. Step 5: Solve the equation: 2 × 5 mL = 10 mL.

So, the nurse should administer 10 mL of fluoxetine.

A. Altered body image. B. Amenorrhea. C. Hyperactivity. D. Bradycardia. E. Verbalized desire to gain weight.

Correct Answer is ["A","B","C","D"]

Explanation

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.
