A nurse is making a follow-up call to client who has a new prescription for ACE inhibitor to treat hypertension. The client reports lightheadedness upon standing. Which of the following statements should the nurse make?

*Restrict your daily fluid intake."

*Take a daily potassium supplement."

*Discontinue this medication if this occurs again."

"Sit back down for a few minutes when this occurs."

Answer and Explanation

The Correct Answer is D

A) *Restrict your daily fluid intake: Restricting fluid intake is not recommended for a client experiencing lightheadedness upon standing, especially when taking an ACE inhibitor. In fact, maintaining adequate hydration is important to help prevent hypotension, which could be exacerbated by fluid restriction. The lightheadedness may be due to orthostatic hypotension, which is a common side effect of ACE inhibitors.

B) *Take a daily potassium supplement: ACE inhibitors can increase potassium levels in the blood, potentially leading to hyperkalemia. For most clients, taking a potassium supplement is not necessary unless specified by the healthcare provider. In fact, many clients taking ACE inhibitors need to avoid excessive potassium intake, unless directed otherwise, to prevent dangerous potassium levels.

C) *Discontinue this medication if this occurs again: The nurse should not advise the client to discontinue the medication without consulting the healthcare provider. Lightheadedness upon standing is a common side effect of ACE inhibitors due to their blood pressure-lowering effects, and the healthcare provider should be notified if this becomes problematic. The decision to change or discontinue the medication should be made by the provider.

D) "Sit back down for a few minutes when this occurs": This is the most appropriate advice. Lightheadedness upon standing can be a sign of orthostatic hypotension, which is a known side effect of ACE inhibitors. The client should be instructed to sit down and rest when they experience these symptoms. If necessary, they should stand up slowly to allow their body to adjust to changes in position, which can help alleviate the lightheadedness.

Correct Answer is B

Explanation

A) Arterial blood gases: Arterial blood gas (ABG) tests are typically used to assess respiratory and metabolic function, including the balance of oxygen and carbon dioxide in the blood. While important in many clinical situations, ABGs are not specifically relevant for monitoring a client on levothyroxine, as it does not directly affect gas exchange or acid-base balance.

B) Thyroid stimulating hormone (TSH): TSH is the most important laboratory test to monitor in a client taking levothyroxine, as this medication is used to replace or supplement thyroid hormone levels. Levothyroxine directly affects thyroid hormone levels in the body, so monitoring TSH levels is essential for determining whether the medication dosage needs to be adjusted. Elevated TSH levels may indicate that the dose is too low, while low levels may suggest an overdose.

C) Prothrombin time: Prothrombin time (PT) is used to assess blood clotting and coagulation status. While certain thyroid conditions can influence coagulation, PT is not a routine test to monitor in clients on levothyroxine therapy unless there are specific concerns related to bleeding or clotting. It is not the most relevant test for monitoring thyroid function in this context.

D) Blood urea nitrogen (BUN): Blood urea nitrogen (BUN) levels reflect kidney function and hydration status. While kidney function is always important to monitor, BUN is not specifically used to assess the effects of levothyroxine therapy. It would not provide direct information regarding the effectiveness of the medication or the thyroid status of the client.

Correct Answer is ["0.25"]

Explanation

Identify the desired dose:

The doctor has ordered 0.5 mg of haloperidol.

Identify the available medication concentration:

The available haloperidol oral concentrate is 2 mg/mL.

Set up the calculation:

We need to find out how many mL are needed to administer 0.5 mg of the medication. We can use the following formula:

(Desired dose) / (Concentration) = Volume to administer

Plug in the values and calculate:

(0.5 mg) / (2 mg/mL) = 0.25 mL
