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. Which set of guidelines is intended to assess nutrient adequacy or plan intake of a population group, not individuals?

• A. RDA
• B. EAR
• C. DRA
• D. UL

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is the correct choice because it is specifically designed to assess the nutrient adequacy of population groups, not individuals. The Recommended Dietary Allowance (RDA) (choice A) is the average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy individuals in a particular life stage and gender group. The Dietary Reference Intake (DRI) (choice C) includes the EAR, RDA, Adequate Intake (AI), and UL, making it a broader set of nutrient reference values. The Tolerable Upper Intake Level (UL) (choice D) is the highest average daily nutrient intake level that is likely to pose no risk of adverse health effects to almost all individuals in the general population.

3. A client with gastroesophageal reflux disease is being taught by a nurse about managing the illness. Which of the following recommendations should the nurse include in the teaching?

• A. Limit fluid intake not related to meals.
• B. Chew on mint leaves to relieve indigestion.
• C. Avoid eating within 3 hours of bedtime.
• D. Season foods with black pepper.

Correct answer: C

Rationale: The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.

4. A client receiving continuous enteral tube feeding reports cramping and abdominal distention. Which of the following actions should the nurse take?

• A. Check for gastric residual.
• B. Apply low intermittent suction.
• C. Increase the rate of the feeding.
• D. Request a higher-fat formula.

Correct answer: A

Rationale: When a client on continuous enteral tube feeding experiences cramping and abdominal distention, the nurse should check for gastric residual. This assessment helps determine if the client is tolerating the feeding well or if there is a potential issue such as feeding intolerance. Applying low intermittent suction, increasing the feeding rate, or requesting a higher-fat formula are not appropriate actions for addressing the reported symptoms and may exacerbate the client's discomfort or lead to further complications.

5. Which nutrient has the highest satiety value?

• A. Complex carbohydrates
• B. High-quality protein
• C. Low-quality protein
• D. Fat

Correct answer: D

Rationale: Fat has the highest satiety value among the listed nutrients. It slows down digestion, stays in the stomach longer, and provides a sustained release of energy, leading to increased feelings of fullness and satisfaction. Complex carbohydrates can also contribute to satiety, but fat generally has a stronger effect. High-quality protein is important for satiety as well, but it is generally not as filling as fat. Low-quality protein does not have as significant satiating effects as high-quality protein or fat.
