1. A nurse that is always ready to answer for all his actions and decision is said to be:
- A. Accountable C. Critical thinker
- B. Responsible D. Assertive
- C.
- D.
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 type of medication is most likely to induce xerostomia?
- A. Antibiotics
- B. Diuretics
- C. Local anesthetics
- D. Anticholinergics
Correct answer: D
Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.
3. Which of the following are absorbed into the bloodstream without needing additional digestion?
- A. amino acids
- B. monosaccharides
- C. glycerol
- D. all of the above
Correct answer: D
Rationale: Amino acids, monosaccharides, and glycerol are absorbed directly into the bloodstream without requiring further digestion.
4. Bones continuously lose and gain minerals. This ongoing process is called?
- A. reorganization
- B. reorienting
- C. demineralizing
- D. remodeling
Correct answer: D
Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.
5. 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.
