1. Transmission of HIV from an infected individual to another person occurs:
- A. Most frequently in nurses with needlesticks
- B. Only if there is a large viral load in the blood
- C. Most commonly as a result of sexual contact
- D. In all infants born to women with HIV infection
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.
2. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?
- A. cantaloupe
- B. eggs
- C. carrots
- D. all of the above
Correct answer: D
Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.
3. Mr. Bruno asks what the “normal†allowable salt intake is. Your best response to Mr. Bruno is:
- A. 1 tsp of salt/day with iodine and sprinkle of MSG
- B. 5 gms per day or 1 tsp of table salt/day
- C. 1 tbsp of salt/day with some patis and toyo
- D. 1 tsp of salt/day but no patis and toyo
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.
4. What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?
- A. Dumping syndrome
- B. Gastritis
- C. Gastric outlet obstruction
- D. Hypochlorhydria
Correct answer: C
Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.
5. What physiologic role does magnesium 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: B
Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.
