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

Correct Answer is A
Explanation
Radiation therapy can cause immunosuppression, which increases the risk of infection. The nurse should monitor the client for signs of infection such as fever, chills, malaise, or purulent drainage.
- Examine the skin for generalized urticaria. This is not a common side effect of radiation therapy, as urticaria is an allergic reaction that causes hives or welts on the skin. Radiation therapy can cause localized skin irritation, erythema, or dryness, but not generalized urticaria.
- Review laboratory test results for low hemoglobin. This is not a direct effect of radiation therapy, as hemoglobin is a component of red blood cells that carries oxygen in the blood. Radiation therapy can cause anemia, which is a low number of red blood cells, but not necessarily low hemoglobin.
- Monitor the mouth for signs of xerostomia. This is not relevant for a client who receives radiation therapy to treat lung cancer, as xerostomia is dry mouth caused by reduced salivary gland function. This can occur in clients who receive radiation therapy to treat head and neck cancer, but not lung cancer.

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.
