The nurse is observing continuous cardiac monitoring for assigned clients. Which of the following cardiac rhythms would immediate follow-up?
Correct Answer: C
Rationale: Ventricular fibrillation (VF) is a lethal dyshythmia characterized by disorganized electrical activity in the heart ventricles. Because
of this erratic electrical activity, the heart muscles lose the ability to contract, resulting in loss of blood flow and pulse (ie, cardiac
arrest). Nurses who identify a client with VF should immediately check the pulse, start CPR, and prepare the client for defibrillation

As a general guide for emergency management of acute alcohol intoxication, it is important for the nurse initially to obtain data regarding which of the following?
- A. What and how much the client drinks, according to family and friends
- B. The blood alcohol level of the client
- C. The blood pressure level of the client
- D. The blood glucose level of the client
Correct Answer: B
Rationale: Blood alcohol levels are generally obtained to determine the level of intoxication. The amount of alcohol consumed determines how much medication the client needs for detoxification and treatment. Reports of alcohol consumption are notoriously inaccurate.

- A. impaired iron transfer from the mother
- B. excessive intake of meat products

A client with a history of renal calculi passes a stone made up of calcium oxalate. Which of the following diet instructions should be given to the client?
- A. Increase intake of meats, eggs, fish, plums, and cranberries.
- B. Avoid citrus fruits and juices.
- C. Avoid dark green, leafy vegetables.
- D. Increase intake of dairy products.

Rationale: Dark green, leafy vegetables are high in oxalates, which contribute to calcium oxalate stones. Meats and dairy increase other stone types, and citrus juices are beneficial.
The nurse is to observe the client for shock. The client's admitting vital signs are blood pressure (BP)=116/70, pulse=86, and respirations=24. Which finding, if observed, would be most suggestive of shock?
- A. BP=140/60
- B. Pulse=100
- C. BP=114/68
- D. Pulse=60
Correct Answer: B
Rationale: Increased pulse (tachycardia) is a hallmark of shock, compensating for reduced volume. Stable or slightly varied BP and low pulse are less indicative.
A nurse has administered several blood transfusions over 3 days to a 12 year-old client with Thalassemia. What lab value should the nurse monitor closely during this therapy?
- A. Hemoglobin
- B. Red Blood Cell Indices
- C. Platelet count
- D. Neutrophil percent
Correct Answer: A
Rationale: Hemoglobin should be in a therapeutic range of approximately 10 g/dl (100 g). This level is low enough to foster the patient’s own erythropoiesis without enlarging the spleen.
