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. You notice that Miss Kate, a bread vendor, receives and changes money, then holds the bread without washing her hands. As a nurse, what should you say to Miss Kate?

• A. Miss, don't touch the bread, I'll be the one to pick it up.
• B. Miss, please wash your hands before you pick up the bread.
• C. Miss, use a pick-up forceps when picking up the bread.
• D. Miss, your hands are dirty, I guess I'll try another bread shop.

Correct answer: B

Rationale: The correct answer is B, as it emphasizes the importance of hygiene in food handling, which is crucial to prevent the spread of germs and diseases. The other options do not address the root of the issue, which is the unhygienic handling of food. Option A avoids direct confrontation but does not educate the vendor on proper hygiene. Option C, although it suggests a hygienic method, may not be practical or available in all situations. Option D is an avoidance strategy rather than a way to address the problem.

3. Overweight and obesity often accompany conditions such as _____ that limit mobility or result in short stature, which can lead to feeding difficulties.

• A. Parkinson's disease
• B. muscular dystrophy
• C. Down syndrome
• D. multiple sclerosis

Correct answer: C

Rationale: The correct answer is C, Down syndrome. Down syndrome is often associated with short stature and limited mobility, which can contribute to feeding difficulties and obesity. Parkinson's disease (choice A) primarily affects motor function, but it is not typically associated with short stature. Muscular dystrophy (choice B) primarily impacts muscle strength and does not necessarily lead to short stature. Multiple sclerosis (choice D) is a neurological condition affecting the central nervous system and does not directly cause short stature or feeding difficulties as seen in Down syndrome.

4. For individuals with lactose intolerance, which of the following foods should be avoided?

• A. Eggs
• B. Milk
• C. Almonds
• D. Beef

Correct answer: B

Rationale: Individuals with lactose intolerance lack the enzyme lactase needed to break down lactose. Milk contains lactose, a sugar found in dairy products, and should be avoided by individuals with lactose intolerance. Choices A, C, and D are not sources of lactose and are generally well-tolerated by individuals with lactose intolerance.

5. A nurse is providing teaching to the parent of a toddler about appropriate snacks. Which of the following foods should the nurse include?

• A. Sliced bananas
• B. Raw celery
• C. Peanut butter
• D. Grapes

Correct answer: A

Rationale: The correct answer is sliced bananas. Bananas are a good choice for toddlers as they are easy to chew, rich in potassium, and generally well-tolerated. Raw celery (Choice B) may pose a choking hazard due to its fibrous nature. Peanut butter (Choice C) should be avoided as it can also be a choking hazard and may cause an allergic reaction in some children. Grapes (Choice D) are a choking hazard for toddlers due to their size and shape, so they should be cut into smaller pieces or avoided altogether.
