Nursing Elites

1. The counting of sponges is done by the Surgeon together with the:

• A. Circulating nurse
• B. Scrub nurse
• C. Assistant surgeon
• D. Nurse supervisor

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.

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

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

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.

3. In which of the following conditions does a person need to sit, stand, or use multiple pillows when lying down?

• A. Orthopnea
• B. Dyspnea
• C. Eupnea
• D. Apnea

Correct answer: A

Rationale: The correct answer is Orthopnea. Orthopnea is a medical condition in which a person has difficulty breathing while lying down. To alleviate this difficulty, the person may need to sit, stand, or use multiple pillows. On the other hand, Dyspnea refers to general shortness of breath which is not specifically related to the position of the body. Eupnea is the term for normal, unlabored breathing, and Apnea is a condition characterized by the cessation of breathing. Thus, none of these other choices directly relate to the need to adjust body position or use aids like multiple pillows to breathe comfortably when lying down.

4. Among people who are ill, significant weight loss may be masked by?

• A. dehydration
• B. a large tumor
• C. drug therapy
• D. fluid retention

Correct answer: D

Rationale: Fluid retention can mask weight loss in ill individuals as the retained fluid adds to body weight, making it difficult to detect true fat or muscle loss. Dehydration (Choice A) would actually lead to weight loss rather than masking it. While a large tumor (Choice B) could contribute to weight loss, it would not mask the weight loss itself. Drug therapy (Choice C) may cause side effects, including weight changes, but it is unlikely to mask significant weight loss in the same way that fluid retention does.

5. Does the hypothalamus control the feeling of hunger and satiety, and are fats the best nutrient in creating the feeling of satiety?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Yes, the hypothalamus plays a crucial role in regulating hunger and satiety. Fats are indeed known to be highly satiating nutrients, helping to create a feeling of fullness and satisfaction after a meal. Therefore, both statements are true. Choice B is incorrect because fats are indeed effective in promoting satiety.
