Ordered: Potassium chloride (K-Dur) 60 mEq

Available: Potassium chloride (K-Dur) 20 mEq/15 mL

Administer: _____mL

Answer and Explanation

The Correct Answer is ["45"]

To calculate the amount of potassium chloride (K-Dur) solution to administer, we need to use the following formula:

mL to administer = ordered dose (mEq) / available dose (mEq/mL) x mL

Plugging in the values from the question, we get:

mL to administer = 60 mEq / (20 mEq / 15 mL) x 15 mL

Simplifying the equation, we get:

mL to administer = 60 mEq x 15 mL / 20 mEq

mL to administer = 45 mL

Therefore, the nurse should administer 45 mL of potassium chloride (K-Dur) solution to the patient.

Correct Answer is A

Explanation

A. Ask the client if she is having pain.

This option recognizes the potential relationship between pain and elevated blood pressure. Assessing the client for pain is crucial, as pain can contribute to increased blood pressure.

B. Request a prescription for an antianxiety medication.

This option assumes that anxiety might be the cause of the elevated blood pressure. However, without further assessment, it may not be appropriate to jump to prescribing medication for anxiety.

C. Request a prescription for an antihypertensive medication.

Initiating antihypertensive medication without further assessment may not be the most appropriate first step, especially if the elevated blood pressure is related to pain or another temporary factor.

D. Return in 30 minutes to recheck the client’s blood pressure.

While monitoring blood pressure is important, waiting 30 minutes without further assessment or intervention might delay addressing the underlying issue, especially if it is related to pain or another acute problem.

A. Dorsal surface of the foot B. Pinnae of the ears C. Dorsal surface of the hand D. Conjunctivae

Correct Answer is C

Explanation

A. Dorsal surface of the foot:

The skin on the dorsal surface of the foot may have more pigmentation, making it potentially more challenging to detect cyanosis in individuals with dark skin.

B. Pinnae of the ears:

The ears may have variable pigmentation, and the presence of hair can affect the visibility of cyanosis. The skin on the pinnae may not be as thin as the skin on the dorsal surface of the hand.

C. Dorsal surface of the hand

When assessing for cyanosis in a client with dark skin, the nurse should examine areas with less pigmentation or areas where the skin is thin. The dorsal surface of the hand is often a suitable site, as it is less pigmented and can show bluish discoloration if cyanosis is present.

D. Conjunctivae:

The conjunctivae (the mucous membranes lining the inner surface of the eyelids and covering the white part of the eyes) are not a reliable site for assessing cyanosis in individuals with dark skin. Mucous membranes may not show cyanosis as prominently as the skin.
