A physician orders Lithium 1.2 grams/day in three divided doses PO for a client with bipolar disorder. The medication is supplied as 300 mg/5 mL. How much will 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.)

Answer and Explanation

The Correct Answer is ["6.7"]

Step 1: Convert the total daily dose from grams to milligrams. 1.2 grams × 1000 = 1200 milligrams Result: 1200 milligrams

Step 2: Divide the total daily dose by the number of doses per day to find the dose per administration. 1200 milligrams ÷ 3 = 400 milligrams per dose Result: 400 milligrams per dose

Step 3: Determine how many milliliters are needed for each dose. The medication is supplied as 300 mg/5 mL. 400 milligrams ÷ 300 milligrams = (400 ÷ 300) = 1.3333 Result: 1.3333

Step 4: Multiply the result by the volume (5 mL) to find the volume needed per dose. 1.3333 × 5 mL = 6.6665 mL Result: 6.6665 mL

Step 5: Round the result to the nearest tenth. 6.6665 mL rounded to the nearest tenth = 6.7 mL Result: 6.7 mL

The nurse will administer 6.7 mL per dose.

Correct Answer is C

Explanation

Choice A Reason: Anorexia Nervosa

Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight and a distorted body image, leading to restricted food intake and excessive weight loss. Individuals with anorexia nervosa often have a relentless pursuit of thinness and may engage in extreme dieting, excessive exercise, and other behaviors to lose weight. While eliminating specific foods can be a part of anorexia nervosa, the primary focus is on weight loss and body image rather than the purity or healthiness of the food.

Choice B Reason: Rumination Disorder

Rumination disorder involves the repeated regurgitation of food, which may be re-chewed, re-swallowed, or spit out. This condition is more common in infants and individuals with developmental disabilities but can occur in people of all ages. The behavior is typically involuntary and not related to concerns about food purity or healthiness. Therefore, it does not align with the client’s report of eliminating specific foods to “eat clean.”

Choice C Reason: Orthorexia

Orthorexia is an eating disorder characterized by an obsession with eating foods that one considers healthy or pure. Individuals with orthorexia may eliminate entire food groups, such as sugars, carbohydrates, or dairy, in their quest to maintain a “clean” diet6. This condition can lead to malnutrition and social isolation due to the restrictive nature of the diet. The client’s report of eliminating specific foods to “eat clean” is a clear indication of orthorexia.

A. Expect hyperactivity as a common adverse effect. B. Give the dose in the morning to help prevent insomnia. C. Avoid crowds due to the increased risk for infection. D. Limit caloric intake to prevent excessive weight gain.

Correct Answer is B

Explanation

The correct answer is b.

Choice A Reason:

Expect hyperactivity as a common adverse effect. This statement is incorrect. Atomoxetine is a non-stimulant medication used to treat ADHD and does not typically cause hyperactivity. Instead, it helps improve attention and reduce hyperactivity and impulsiveness. Common side effects of atomoxetine include nausea, vomiting, upset stomach, constipation, dry mouth, loss of appetite, mood changes, feeling tired, dizziness, urination problems, or impotence.

Choice B Reason:

Give the dose in the morning to help prevent insomnia. This statement is correct. Atomoxetine should be taken in the morning to help prevent insomnia, as taking it later in the day can interfere with sleep. The medication can be taken with or without food, and if a second dose is prescribed, it is typically taken in the late afternoon or early evening.

Choice C Reason:

Avoid crowds due to the increased risk for infection. This statement is incorrect. Atomoxetine does not increase the risk of infection, and there is no need to avoid crowds while taking this medication3. Common side effects do not include an increased risk of infection.

Choice D Reason:

Limit caloric intake to prevent excessive weight gain. This statement is incorrect. Atomoxetine is more likely to cause weight loss rather than weight gain. It can decrease appetite, which may lead to weight loss in some patients. Therefore, limiting caloric intake is not necessary while taking atomoxetine.
