A nurse is preparing to administer levothyroxine 50 micrograms to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose?

(Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To calculate how many tablets of levothyroxine the nurse should administer, we'll need to convert the dose to the same unit as the available tablets. Here's the step-by-step process:

Convert the desired dose to milligrams (mg): 50 micrograms (mcg) = 50 / 1000 mg (since 1 mg = 1000 mcg) 50 mcg = 0.05 mg

Now, find out how many tablets of 0.025 mg each are required to achieve the desired dose: Number of tablets = Desired dose (in mg) / Tablet strength (in mg) Number of tablets = 0.05 mg / 0.025 mg Number of tablets = 2 tablets

Therefore, the nurse should administer 2 tablets per dose.

Correct Answer is C

Explanation

A. Incorrect. The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45).

B. Incorrect. The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45).

C. Correct. The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).

D. Incorrect. The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).

A. Hypoxemia B. Tension pneumothorax. C. Malignant hypertension D. Atelectasis

Correct Answer is B

Explanation

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.
