Question 1 of 5
Which type of diet consists of only plant-based foods?
Correct Answer: D
Rationale: The correct answer is D: Vegan diet. A vegan diet consists of only plant-based foods, excluding all animal products. This is because vegans do not consume any animal-derived products, including meat, dairy, eggs, and honey. The other choices, A, B, and C, all include some form of animal products in the diet. Lacto-ovo vegetarian diet (A) includes dairy and eggs, lacto-vegetarian diet (B) includes dairy but not eggs, and ovo-vegetarian diet (C) includes eggs but not dairy. Therefore, the vegan diet (D) is the only option that aligns with being entirely plant-based.
Question 2 of 5
People who have diabetes may have ______ chemical substance(s) produced when the body burns fat for energy or fuel in their urine.
Correct Answer: D
Rationale: The correct answer is D: Ketones. When the body burns fat for energy in the absence of enough insulin, ketones are produced. People with diabetes may have ketones in their urine due to inadequate insulin levels. Reagents (A) are substances used in chemical reactions, not produced in the body. Glucose (B) is a sugar and is typically found in the blood, not urine in high amounts. Insulin (C) is a hormone that regulates blood sugar levels and is not typically found in urine.
Question 3 of 5
Which of the following statements is true of pressure injuries?
Correct Answer: D
Rationale: The correct answer is D because pressure injuries can lead to life-threatening infections due to compromised skin integrity. When pressure is applied for a prolonged period, blood flow is restricted, leading to tissue damage and making the skin vulnerable to infection. This can result in serious complications if not treated promptly. Choices A, B, and C are incorrect. A pressure injury may not always appear as a deep crater at the initial stage; they can vary in appearance. While pressure injuries can be challenging to heal, they can cause significant pain and discomfort. Finally, although preventing pressure injuries can be difficult, it is not impossible with proper care and interventions.
Question 4 of 5
What should a resident who has asthma avoid?
Correct Answer: D
Rationale: The correct answer is D: Strong smells. Asthma patients should avoid strong smells as they can trigger asthma symptoms. Strong smells like perfumes, smoke, cleaning chemicals can irritate the airways and lead to breathing difficulties. Inhalers (choice A) are actually necessary for asthma management. Talking (choice B) and fluids (choice C) do not directly impact asthma symptoms. In summary, the other choices are incorrect as they do not address the specific trigger for asthma symptoms, which is exposure to strong smells.
Question 5 of 5
The tiny bones within the middle ear that pick up vibrations and send impulses to the brain are the
Correct Answer: A
Rationale: The correct answer is A: Ossicles. Ossicles are the tiny bones in the middle ear that transmit sound vibrations from the eardrum to the cochlea. The three ossicles are the malleus, incus, and stapes. They amplify and transmit sound waves, enabling the brain to interpret sound accurately. B: Eardrums are incorrect because they are the thin membrane that vibrates when sound waves hit it, but they do not send impulses to the brain. C: Cochleas are incorrect because they are the spiral-shaped organ in the inner ear responsible for converting sound vibrations into electrical signals to be sent to the brain. D: Auricles are incorrect because they are the visible part of the outer ear that helps collect sound waves, but they do not pick up vibrations and send impulses to the brain.
