A client is prescribed levothyroxine 200 mcg PO daily before breakfast. In the medication room are tablets labelled 0.05 mg/tablet. How many tablet(s) will you administer to the client? Fill in the blank with a numeric value. Answer to the nearest whole tablet
The Correct Answer is ["4"]
Convert micrograms (mcg) to milligrams (mg):
The prescribed dose is 200 mcg.
We know that 1 mg = 1000 mcg.
Therefore, 200 mcg = 200 / 1000 = 0.2 mg.
Calculate the number of tablets:
Each tablet contains 0.05 mg of levothyroxine.
The desired dose is 0.2 mg.
We can use the following formula: (Desired dose) / (Tablet strength) = Number of tablets
(0.2 mg) / (0.05 mg/tablet) = 4 tablets

Correct Answer is B
Explanation
A. "Take this medication with a small sip of water or on an empty stomach":
This response is not ideal for calcium carbonate. Calcium carbonate is typically taken with food to help increase its absorption and to reduce the risk of gastrointestinal discomfort, such as constipation or bloating. Taking it on an empty stomach could cause irritation and is not the standard guideline for this medication.
B. "This medication should be taken two hours before other medications":
This is the most appropriate response. Calcium carbonate can interfere with the absorption of other medications, particularly those that require an acidic environment for proper absorption, such as certain antibiotics (e.g., tetracyclines) and thyroid medications. Therefore, taking calcium carbonate two hours before or after other medications helps to prevent such interactions.
C. "Place this medication underneath your tongue and let it dissolve":
Calcium carbonate is typically taken orally in tablet form, not sublingually. The medication should not be dissolved under the tongue, as it is not designed for that route of administration. This would be an incorrect instruction.
D. "You can take as many doses of this medication as you need":
This statement is not accurate. Calcium carbonate should be taken as prescribed and in the correct dosage to avoid side effects such as hypercalcemia or kidney stones. Overuse of calcium supplements can lead to serious complications, and it should not be taken "as needed" without specific instructions from the healthcare provider.
Correct Answer is C
Explanation
A) Problems that cause severe discomfort to the client: While addressing discomfort is important in providing holistic care, it is not the highest priority in nursing. The nurse’s primary focus should be on life-threatening issues or those that could deteriorate the client’s condition rapidly. Severe discomfort can be managed once immediate threats to life are addressed.
B) Problems the client deems most important: Although it’s essential to consider the client’s perspective and involve them in their care plan, problems that are most important to the client may not always be the most urgent or life-threatening. For example, the client may prioritize pain management, but addressing life-threatening issues must always take precedence.
C) Problems that are immediately life-threatening for the client: This is the correct answer. According to Maslow’s hierarchy of needs and the nursing prioritization framework, life-threatening problems should always be the nurse's first priority. These are issues that, if not addressed immediately, can lead to death or severe complications. For instance, airway obstruction, severe bleeding, or shock would require immediate intervention.
D) Problems that are identified as priority by the physician: While the physician’s orders and priorities should be taken into consideration, the nurse must independently assess and prioritize care based on the overall health status of the client. This includes using clinical judgment to identify life-threatening conditions, even if they are not explicitly stated in the physician’s orders. Nurses are trained to identify priority issues through their assessments and are responsible for making decisions that ensure the client’s safety.
