When teaching a mother of a 4-month-old with diarrhea about the importance of preventing dehydration, the nurse would inform the mother about the importance of feeding her child:

  1. Fruit juices
  2. Diluted carbonated drinks
  3. Soy-based, lactose-free formula
  4. Regular formulas mixed with electrolyte solutions

Answer(s): C

Explanation:

(A) Diluted fruit juices are not recommended for rehydration because they tend to aggravate the diarrhea. (B) Diluted soft drinks have a high-carbohydrate content, which aggravates the diarrhea. (C) Soy-based, lactose-free formula reduces stool output and duration of diarrhea in most infants. (D) Regular formulas contain lactose, which can increase diarrhea.

When a client questions the nurse as to the purpose of exercise electrocardiography (ECG) in the diagnosis of cardiovascular disorders, the nurse's response should be based on the fact that:

  1. The test provides a baseline for further tests
  2. The procedure simulates usual daily activity and myocardial performance
  3. The client can be monitored while cardiac conditioning and heart toning are done
  4. Ischemia can be diagnosed because exercise increasesO2 consumption and demand

Answer(s): D

Explanation:

(A) The purpose of the study is not to provide a baseline for further tests. (B) The test causes an increase in O2 demand beyond that required to perform usual daily activities. (C) Monitoring does occur, but the test is not for the purpose of cardiac toning and conditioning. (D) Exercise ECG, or stress testing, is designed to elevate the peripheral and myocardial needs for O2 to evaluate the ability of the myocardium and coronary arteries to meet the additional demands.

When a client is receiving vasoactive therapy IV, such as dopamine (Intropin), and extravasation occurs, the nurse should be prepared to administer which of the following medications directly into the site?

  1. Phentolamine (Regitine)
  2. Epinephrine
  3. Phenylephrine (Neo-Synephrine)
  4. Sodium bicarbonate

Answer(s): A

Explanation:

(A) Phentolamine is given to counteract the-adrenergic effects that cause ischemia and necrosis of local tissue. (B) Epinephrine is an endogenous catecholamine that produces vasoconstriction and increases heart rate and contractility. (C) Phenylephrine causes constriction of arterioles of skin, mucous membranes, and viscera, which in turn can cause ischemia and necrosis. (D) Sodium bicarbonate is an alkalinizing agent that is incompatible with dopamine.

i just took my oracle exam and let me tell you, this exam dumps was a lifesaver! without them, iam not sure i would have passed. the questions were tricky and the answers were obscure, but the exam dumps had everything i needed. i would recommend to anyone looking to pass their oracle exams with flying colors (and a little bit of cheating) lol.

22. if you need to make sure that one computer in your hot-spot network can access the internet without hot-spot authentication, which menu allows you to do this? answer is ip binding and not wall garden. wall garden allows specified websites to be accessed with users authentication to the hotspot
