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. What health instruction will enhance regulation of a colostomy (defecation) of clients?

• A. Irrigate after lunch everyday
• B. Eat fruits and vegetables in all three meals
• C. Eat balanced meals at regular intervals
• D. Restrict exercise to walking only

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 assessing a client who has malnutrition. Which of the following findings should the nurse expect?

• A. Increased vital capacity
• B. Dry skin
• C. Heat intolerance
• D. Decreased mental status

Correct answer: D

Rationale: Malnutrition can lead to a variety of physical and mental symptoms. One common manifestation of malnutrition is a decreased mental status, which includes confusion, lethargy, and cognitive impairment. Dry skin is a typical finding in malnutrition due to the lack of essential nutrients needed for skin health. Heat intolerance is not a direct consequence of malnutrition. While malnutrition can affect respiratory function, it typically leads to decreased vital capacity rather than increased. Therefore, the correct answer is decreased mental status.

4. A client with hypertension is being educated by a nurse about a heart-healthy diet. Which of the following statements indicates that the client understands the teaching?

• A. I will get 15% of my total daily calories from saturated fats.
• B. I will decrease the potassium in my diet.
• C. I will limit my daily sodium intake to 3 grams.
• D. I will eat five 8-ounce servings of fruit daily.

Correct answer: C

Rationale: The correct answer is C. Limiting daily sodium intake to 3 grams is crucial in managing blood pressure and is a fundamental aspect of a heart-healthy diet. High sodium intake can contribute to hypertension and cardiovascular issues. Choices A, B, and D are incorrect because getting 15% of daily calories from saturated fats, decreasing potassium intake, and eating five servings of fruit do not directly address the management of hypertension through sodium restriction.

5. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.
