A prn order must indicate the minimum time between doses such as q4h
True
False
The Correct Answer is B
A PRN order does not necessarily indicate the minimum time between doses. PRN stands for "pro re nata," which means "as needed." When a medication is ordered PRN, the healthcare provider should also indicate the frequency or the minimum time between doses, for example, "PRN every 4 hours" or "PRN up to 3 times a day." However, the specific frequency or time between doses may vary depending on the patient's condition and response to the medication, so it is important to follow the healthcare provider's instructions and assess the patient's response before administering the medication again.

Correct Answer is ["Crushed or broken before the administration"]
Explanation
Enteric-coated tablets and time-released tablets should never be crushed or broken before administration. Here are reasons why enteric-coated tablets and time-released tablets should never be crushed: 1. Effectiveness: Enteric-coated tablets are designed to resist the acidic environment of the stomach and dissolve in the alkaline environment of the small intestine. Crushing these tablets will alter their absorption pattern and effectiveness.
2. Safety: Time-released tablets are designed to slowly release the medication over an extended period, which helps to maintain a consistent therapeutic level in the body. Crushing these tablets can result in an immediate release of the entire dose, which can cause an overdose or adverse reactions.
3. Irritation: Crushing enteric-coated or time-released tablets can cause irritation to the throat, mouth, and airways, leading to coughing, choking, or breathing difficulties.
4. Accuracy: When tablets are crushed, the amount of medication that is delivered may be inaccurate, which can lead to underdosing or overdosing.
Correct Answer is ["A","C","D"]
Explanation
Norepinephrine and epinephrine are catecholamines released by the adrenal medulla during the "fight or flight" response. They have several physiological effects, including increasing heart rate, pupil dilation, and blood pressure. Additionally, epinephrine causes bronchodilation, while norepinephrine causes vasoconstriction. Therefore, the nurse should monitor the client for signs of hypertension, tachycardia, and increased respiratory rate.
Increased urine output, is incorrect because catecholamines decrease urine output by activating the renin-angiotensin-aldosterone system.
Constriction of blood vessels is incorrect because norepinephrine causes vasoconstriction, not vasodilation.
