1. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?
- A. The pulse is easier to palpate due to the rigidity of the blood vessels.
- B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
- C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
- D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.
Correct answer: B
Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.
2. The most accurate reading for a temperature is done:
- A. Orally
- B. Aurally through a clean canal
- C. Rectally
- D. Axially
Correct answer: B
Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.
3. What is the proper personal protective equipment necessary for collecting a sputum specimen?
- A. Gloves and face mask
- B. Level Three Biocontainment uniforms
- C. Eye protection and shoe covers
- D. Splash shield and face mask
Correct answer: A
Rationale: When collecting a sputum specimen, it is crucial to protect against potential airborne droplets that may spread disease. The best personal protective equipment for this task includes gloves and a face mask. Gloves help prevent the spread of contaminants through hand contact, while a face mask protects the respiratory tract from inhaling infectious agents. Choice B, Level Three Biocontainment uniforms, is excessive and unnecessary for routine sputum specimen collection. Choice C, eye protection and shoe covers, does not address the specific risks associated with sputum collection. Choice D, splash shield and face mask, provides additional protection that is not typically required for sputum specimen collection, making it less appropriate than gloves and a face mask.
4. 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.
5. 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.
