1. What is the most common type of kidney stone?
- A. Cystine
- B. Calcium
- C. Struvite
- D. Uric acid
Correct answer: B
Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.
2. Each of the following is a characteristic of fat, except one. Which is the exception?
- A. 95% of ingested fats are absorbed
- B. Hard fats take longer to digest than soft fats
- C. Fats contribute to palatability and flavor of foods
- D. Cooked fats improve the texture of foods
Correct answer: B
Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.
3. 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.
4. A nurse is providing anticipatory guidance to a client who has Phenylketonuria (PKU) and is planning a pregnancy. Which of the following information should the nurse include in the discussion?
- A. Diet sodas should not be consumed more than two or three times a week.
- B. Serum bilirubin should be monitored once or twice a month during pregnancy.
- C. Breastfeeding will not prevent your baby from developing PKU.
- D. A low-protein diet should be followed for three months before conception.
Correct answer: D
Rationale: A low-protein diet should be followed for three months before conception in individuals with PKU who are planning a pregnancy. This diet helps manage PKU by reducing phenylalanine levels, which is crucial for maternal and fetal health. Choices A, B, and C are incorrect. Choice A is not directly related to managing PKU, choice B focuses on a different aspect of care during pregnancy, and choice C is inaccurate as breastfeeding will not prevent a baby from developing PKU.
5. What are the contraindications for using MI Paste?
- A. Children under six
- B. Individuals with a milk casein allergy
- C. Pregnant women
- D. Both A and B
Correct answer: D
Rationale: MI Paste is contraindicated in children under six and in individuals with a milk casein allergy. The reason is that MI Paste contains casein phosphopeptide, which is derived from milk. Therefore, it may cause allergic reactions in those who are sensitive to milk proteins. Pregnant women (Choice C) are not contraindicated for using MI Paste unless they have a known allergy to milk casein. Hence, the correct answer is 'D: Both A and B'.
