1. Which of the following ethical principles refers to the duty to do good?
- A. Beneficence
- B. Fidelity
- C. Veracity
- D. Nonmaleficence
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
2. Which of the following nursing interventions is appropriate after a total thyroidectomy?
- A. Place pillows under your patient’s shoulders.
- B. Raise the knee-gatch to 30 degrees
- C. Keep you patient in a high-fowler’s position.
- D. Support the patient’s head and neck with pillows and sandbags.
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.
3. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?
- A. White Blood Cells 5,200/mm³
- B. Hemoglobin 14 g/dL
- C. Magnesium 1.6 mg/dL
- D. Potassium 3.2 mEq/L
Correct answer: D
Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.
4. Where does most nutrient digestion and absorption occur?
- A. Large intestine
- B. Small intestine
- C. Stomach
- D. Mouth
Correct answer: B
Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
5. What physiological role does phosphorus 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: D
Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.
