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","D"]
Explanation
Answer: A, D
Rationale:
-
A. The medication will prevent wheezing: Albuterol is a bronchodilator, specifically a beta-2 agonist, that relaxes smooth muscles in the airways. This action helps prevent wheezing by reducing airway constriction, making breathing easier for the client.
-
B. The medication will decrease coughing episodes: While albuterol can help reduce cough indirectly by improving airflow and decreasing airway irritation, it is not primarily used to decrease coughing episodes. Other medications, such as corticosteroids, are often more effective for controlling chronic cough related to inflammation.
-
C. The medication will reduce inflammation: Albuterol does not have anti-inflammatory properties. Its primary mechanism is bronchodilation, and anti-inflammatory treatment generally requires corticosteroids, not beta-agonists like albuterol.
-
D. The medication will open the airways: Albuterol works by relaxing bronchial muscles, leading to bronchodilation and allowing the airways to open. This reduces shortness of breath and improves airflow, a primary reason for its use in conditions like asthma.
-
E. The medication will stimulate flow of mucus: Albuterol does not stimulate mucus production; it primarily works by relaxing the airways. However, by improving airflow, it can help clients more effectively expel mucus through coughing.
Correct Answer is B
Explanation
This response is empathetic and therapeutic, as it acknowledges the client's feelings and invites her to express her concerns. It also shows respect and interest in the client's perspective.
a) This response is false reassurance and nontherapeutic, as it dismisses the client's feelings and implies
that the surgery will solve everything.
b) This response is self-disclosure and nontherapeutic, as it shifts the focus from the client to the nurse and
does not address the client's fears.
d) This response is minimizing and nontherapeutic, as it tells the client how to feel and does not acknowledge the client's regret or anxiety.
