1. Why is a pulse oximeter attached to Mr. Dizon's finger?
- A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
- B. To check the level of the patient's tissue perfusion
- C. To measure the effectiveness of the patient's anti-hypertensive medications
- D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop
Correct answer: D
Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
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. The IVP reveals that Fe has small renal calculus that can be passed out spontaneously. To increase the chance of passing the stones, you instructed her to force fluids and do which of the following?
- A. Balanced diet C. Strain all urine
- B. Ambulate more D. Bed rest
- C.
- D.
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. 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.
5. By force of law, therefore, the PRC-Board of Nursing released Resolution No. 14 Series of 1999 entitled: "Adoption of a Nursing Specialty Certification Program and Creation of Nursing Specialty Certification Council." This rule-making power is called:
- A. Quasi-Judicial Power
- B. Regulatory Power
- C. Quasi-Legislative Power
- D. Executive/Promulgating Power
Correct answer: B
Rationale: The correct answer is B: Regulatory Power. Regulatory power involves the authority to create rules and regulations that govern a specific area. In this case, the PRC-Board of Nursing's release of Resolution No. 14 Series of 1999 for the Nursing Specialty Certification Program falls under regulatory power as it establishes guidelines and standards for nursing specialty certification. Choices A, C, and D are incorrect. Quasi-judicial power involves making decisions on rights and obligations, quasi-legislative power involves creating regulations with the force of law, and executive/promulgating power involves enforcing and implementing laws and regulations.
