Ordered: Potassium chloride (K-Dur) 60 mEq
Available: Potassium chloride (K-Dur) 20 mEq/15 mL
Administer: _____mL
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","D","E"]
Explanation
A. Client reports feeling dizzy when sitting up from a supine position.
Dizziness or lightheadedness when moving from a lying down to a sitting or standing position can be indicative of orthostatic hypotension.
B. Client reports feeling palpitations when rising from a supine to a standing position.
Palpitations (feeling of rapid or irregular heartbeat) can be associated with orthostatic changes and may indicate the heart's compensatory response to low blood pressure.
C. Erythema is present on the bilateral lower extremities.
Erythema (redness of the skin) is not typically associated with orthostatic hypotension. This symptom is more likely related to skin conditions or other causes.
D. The client has a temperature of 100.4 F.
Fever (elevated body temperature) is not a direct symptom of orthostatic hypotension. Orthostatic hypotension is primarily related to changes in blood pressure upon assuming an upright position.
E. The client states, “I feel lightheaded when sitting up.”
Lightheadedness upon sitting up or standing is a common symptom of orthostatic hypotension.
Correct Answer is C
Explanation
A. Comatose:
Coma refers to a state of deep unconsciousness where the individual is unresponsive to stimuli, including pain or external stimulation. In the scenario described, the patient is not comatose because they can be awakened by gentle shaking and calling their name.
B. Awake and alert:
This term describes a state of full alertness and responsiveness to the environment. The patient in the scenario is not fully awake and alert since they appear drowsy most of the time and require external stimuli to be awakened.
C. Lethargic:
Lethargy is characterized by drowsiness, reduced alertness, and a sluggish response to stimuli. In the scenario, the patient is described as drowsy most of the time but can be awakened by gentle shaking and calling their name. This aligns with the characteristics of lethargy.
D. Stuporous:
Stupor is a state of reduced responsiveness where the individual can be aroused only by vigorous or painful stimuli. The patient in the scenario does not fit the criteria for stupor as they can be awakened by gentle shaking and calling their name.
