Nursing Elites

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. In the hospital, when you need the medical record of a discharged patient for research you will request permission through:

• A. Doctor in charge
• B. The hospital director
• C. The nursing service
• D. Medical records section

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. A nurse is planning to teach a client about a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid?

• A. Butter
• B. Poultry
• C. Yogurt
• D. Orange juice

Correct answer: D

Rationale: Orange juice is high in potassium and should be avoided in a low-potassium diet. Butter, poultry, and yogurt are low-potassium food choices and can be included in a low-potassium diet. Poultry is a good source of lean protein, yogurt is a good source of calcium and protein, and butter is low in potassium. Therefore, the nurse should instruct the client to avoid orange juice as it is high in potassium, which is not suitable for a low-potassium diet.

4. Monosaccharides are converted into glucose in the liver to provide an energy supply to the cells.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are true. Monosaccharides are indeed converted into glucose in the liver. Glucose, in turn, serves as a primary energy source for cells in the body, providing the necessary fuel for various cellular functions. The liver plays a crucial role in regulating blood glucose levels by converting monosaccharides into glucose and releasing it into the bloodstream when needed. Therefore, option A is the correct choice. Options B, C, and D are incorrect because both statements are accurate in this context.

5. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.
