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. The preferred route of administration of medication in the most acute care situations is which of the following routes?

• A. Intravenous C. Subcutaneous
• B. Epidural D. Intramuscular
• 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.

3. A nurse is providing nutritional information to a client with osteoporosis. Which food should the nurse recommend as being the highest in calcium?

• A. 1 cup carrot strips
• B. 3 oz canned salmon
• C. 1 plain baked potato
• D. 1 cup chopped chicken breast

Correct answer: B

Rationale: Canned salmon with bones is high in calcium.

4. The nurse is completing a nutritional assessment on a client. Which statement made by the client is most concerning to the nurse?

• A. "I notice when I take a vitamin E supplement, I bruise more easily."
• B. "I work nights and rarely go outside during the day."
• C. "I take warfarin, so I need to limit the amount of green leafy vegetables I eat."
• D. "My vitamin supplement has the recommended daily allowance of vitamin A."

Correct answer: A

Rationale: The correct answer is A. Excessive intake of vitamin E can increase the risk of bleeding as it acts as a blood thinner. Bruising easily may indicate too much vitamin E. Choice B is not as concerning as it describes a lifestyle that may lead to vitamin D deficiency due to lack of sunlight exposure. Choice C shows awareness of the interaction between warfarin and vitamin K, which is expected. Choice D indicates knowledge of the vitamin A content in the supplement, which is not a cause for concern.

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.
