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. Digestion, elimination, and ___________ are the three functions of the digestive system.
- A. constriction
- B. relaxation
- C. absorption
- D. peristalsis
Correct answer: C
Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.
3. The Rule of Nines is used to:
- A. determine the amount of the body surface that has been burned
- B. assess the level of oxygen saturation in a body that has been burned.
- C. determine the level of tissue damage that has occurred in a burn.
- D. None of the above.
Correct answer: A
Rationale: The Rule of Nines is used to assess the amount of body surface that has been burned. Most body areas are divided out based on 9%, with the exception of the genitalia, which is only 1%.
4. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?
- A. Rigor mortis
- B. Postmortem decomposition
- C. Algor mortis
- D. Livor mortis
Correct answer: C
Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.
5. What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.
