1. Discharge plans of diabetic clients include injection site rotation. You should emphasize that the space between sites should be:
- A. 6.0 cm.
- B. 5.0 cm.
- C. 2.5 cm.
- D. 4.0 cm.
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
2. Which nutrient is most important for maintaining fluid balance in the body?
- A. Protein
- B. Sodium
- C. Calcium
- D. Vitamin C
Correct answer: B
Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.
3. A factor contributing to the risk for dehydration in the older adult is that _____.
- A. drinking fluids causes loss of bladder control
- B. older adults do not seem to notice mouth dryness as readily as younger people
- C. increased fluid intake will decrease the intake of nutrient-dense foods
- D. changes in intestinal motility contribute to excess fluid loss
Correct answer: C
Rationale: Older adults may not notice mouth dryness as readily as younger individuals, increasing their risk for dehydration, especially if they do not consciously increase fluid intake.
4. 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.
5. Which type of nutritional deficiency results from inadequate absorption?
- A. Unmeasurable
- B. Primary deficiency
- C. Secondary deficiency
- D. Codependent
Correct answer: C
Rationale: The correct answer is C: Secondary deficiency. A nutritional deficiency resulting from decreased intake is called a primary deficiency. On the other hand, a secondary deficiency refers to a vitamin deficiency caused by inadequate absorption or use, increased requirements, excretion, or destruction. Choice A, 'Unmeasurable,' is incorrect as it does not describe a type of nutritional deficiency. Choice B, 'Primary deficiency,' is incorrect as it refers to a deficiency caused by decreased intake, not inadequate absorption. Choice D, 'Codependent,' is incorrect as it is unrelated to the context of nutritional deficiencies.
