1. What physiologic role does magnesium play in the body?

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

2. What are sheets/forms that provide an efficient and time-saving way to record information that must be obtained repeatedly at regular and/or short intervals of time? This does not replace progress notes; instead, it records information on vital signs, intake and output, treatment, postoperative care, postpartum care, and diabetic regimen, etc. These are used whenever specific measurements or observations need to be documented repeatedly. What is this?

Correct answer: A

Rationale: The correct answer is A, Nursing Kardex. Nursing Kardex is a tool used for documenting essential patient information that needs to be recorded repeatedly at regular intervals. It includes vital signs, intake and output, treatment details, postoperative care, postpartum care, and diabetic regimen. This tool is efficient and time-saving for healthcare professionals. Choice B, Graphic Flow Sheets, may be used for visual representation of patient data but is not specifically designed for repeated documentation of essential information. Choice C, Discharge Summary, is a document outlining the patient's care and condition at the time of discharge, not for repeated recording of ongoing data. Choice D, Medicine and Treatment Record, focuses more on specific medications and treatments rather than a comprehensive recording of various patient data needed at regular intervals.

3. Which of the following nursing interventions is appropriate after a total thyroidectomy?

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.

4. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?

Correct answer: B

Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.

5. Each is a portion of the alimentary canal, except one. Which is the exception?

Correct answer: C

Rationale: The correct answer is C, Larynx. The larynx is part of the respiratory system, responsible for voice production and breathing. The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
