1. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

2. While a team effort is necessary in the operating room (OR) for efficient and quality patient care delivery, the number of people in the room should be limited for infection control purposes. Which roles comprise this team?

Correct answer: B

Rationale: The roles typically present in an operating room team include the surgeon, assistants (which may include an assistant surgeon), scrub nurse, circulating nurse, and anesthesiologist. These roles are directly involved in the operation and patient care. Choice B is correct. Choice A includes a radiologist and an orderly, who are not typically part of the immediate surgical team in the OR. Choice C includes a pathologist, who usually works in a laboratory outside of the OR. Choice D includes an intern, who may or may not be part of the team, depending on the specific circumstances and hospital policy. These explanations make choices A, C, and D incorrect.

3. What does a QRS Complex represent in an ECG reading?

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

4. The only IV fluid compatible with blood products is:

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. What symptoms would most likely be associated with a transient ischemic attack?

Correct answer: A

Rationale: The correct answer is A: confusion and difficulty speaking. These symptoms are commonly associated with a transient ischemic attack (TIA), which is a temporary blockage of blood flow to the brain. Choice B, headache and blurred vision, are more indicative of other conditions such as migraines or eye problems. Choice C, chest pain and pressure, are more characteristic of cardiac issues like a heart attack. Choice D, claudication and peripheral edema, are typical of peripheral arterial disease and not typically seen in TIAs.
