A nurse is preparing to administer lithium 300 mg PO every 8 hr. Available is lithium carbonate 150 mg capsules. How many capsules should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
2 capsules
To calculate the number of capsules, use the formula:
capsules = (desired dose in mg / available dose in mg) x 1 capsule
Plug in the given values:
capsules = (300 mg / 150 mg) x 1 capsule
Simplify and solve:
capsules = 2 x 1 capsule
capsules = 2 capsules
Round to the nearest whole number and add a leading zero if needed:
capsules = 2 capsules

Explanation
These actions help to control bleeding, reduce blood pressure, and promote clotting.
a. Tilt the client's head backward. This is not recommended, as it can cause blood to drain into the throat and increase the risk of aspiration, nausea, or vomiting.
d. Instruct the client to blow his nose. This is not advisable, as it can dislodge any clots that have formed and worsen bleeding.
Correct Answer is B
Explanation
White coating in the mouth, also known as oral candidiasis or thrush, is a serious adverse effect of fluticasone/salmeterol, which is a combination of an inhaled corticosteroid and a long-acting beta2 agonist. It is caused by fungal infection of the oral cavity due to suppression of the normal flora by the corticosteroid component. The client should report this symptom to the provider, as it may require antifungal treatment and discontinuation of the medication.
a) Dry oral mucous membranes is a common and mild adverse effect of fluticasone/salmeterol, which can be relieved by drinking water, chewing sugarless gum, or using artificial saliva. It does not require reporting to the provider or stopping the medication.
c) Sedation is not an adverse effect of fluticasone/salmeterol, but it may be caused by other medications, such as antihistamines, opioids, or benzodiazepines. The client should avoid driving or operating machinery if sedated and consult with the provider about possible drug interactions.
d) Increased appetite is not an adverse effect of fluticasone/salmeterol, but it may be caused by other factors, such as stress, boredom, or hormonal changes. The client should maintain a balanced diet and exercise regularly to prevent weight gain and promote health.
