1. Which of the following statements best describes footdrop?
- A. The foot is permanently fixed in the dorsiflexion position
- B. The foot is permanently fixed in the plantar flexion position
- C. The toes of the foot are permanently fanned
- D. The heel of the foot is permanently rotated outward
Correct answer: B
Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.
2. What does the medical term 'diaphoresis' mean?
- A. Profuse vomiting
- B. Profuse sweating
- C. Gasping for air
- D. None of the above
Correct answer: B
Rationale: The correct answer is B: Profuse sweating. Diaphoresis is a medical term that refers to excessive sweating. It is commonly seen in emergency situations such as heart attacks or diabetic episodes. Choice A, 'Profuse vomiting,' is incorrect as diaphoresis is not related to vomiting. Choice C, 'Gasping for air,' is also incorrect as it refers to difficulty breathing, not sweating. Choice D, 'None of the above,' is incorrect as diaphoresis specifically relates to sweating.
3. What is the first aid for frostbite?
- A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
- B. Run warm water over the area to rapidly rewarm the affected area.
- C. Run hot water over the area to warm the area as quickly as possible.
- D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.
Correct answer: A
Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.
4. A urine pregnancy test:
- A. May be negative even if a blood pregnancy test is positive.
- B. Is positive only during the first trimester of pregnancy.
- C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
- D. All of the above.
Correct answer: A
Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.
5. A client is having difficulties reading an educational pamphlet. He cannot find his glasses. In order to read the words, he must hold the pamphlet at arm's length, which allows him to read the information. Which vision deficit does this client most likely suffer from?
- A. Cataracts
- B. Glaucoma
- C. Astigmatism
- D. Presbyopia
Correct answer: D
Rationale: Presbyopia is a condition that occurs when the lens of the eye loses accommodation and is unable to focus light on objects nearby. As a result, clients are unable to see or read items up close but may have success when holding the same item at arm's length. Many clients with presbyopia must wear bifocals, but long-distance vision remains unaffected. Cataracts involve clouding of the eye's lens, leading to blurry vision. Glaucoma is associated with increased intraocular pressure that damages the optic nerve, causing vision loss. Astigmatism is a refractive error where the cornea or lens has an irregular shape, leading to distorted or blurred vision.
