1. 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.
2. 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.
3. Which of these guidelines would a healthcare professional follow when measuring a patient's weight?
- A. The patient is always weighed wearing only undergarments.
- B. The type of scale matters and should be consistent day to day.
- C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
- D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.
Correct answer: D
Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.
4. When taking blood pressures on a variety of people at a health fair, what should the nurse keep in mind?
- A. After menopause, blood pressure readings in women are usually higher than those taken in men.
- B. The blood pressure of an African-American adult is usually higher than that of a non-Hispanic White adult of the same age.
- C. Blood pressure measurements in people who are overweight are usually higher than those of people who are at a normal weight.
- D. A teenager's blood pressure reading may be lower than that of an adult.
Correct answer: B
Rationale: When assessing blood pressures, it is important to consider that the blood pressure of African-American adults is typically higher than that of non-Hispanic White adults of the same age. This is significant as Black individuals in the United States have a higher prevalence of hypertension compared to other groups. Blood pressure readings in women are generally higher than in men after menopause. Additionally, blood pressure measurements in overweight individuals are typically higher than those in individuals of normal weight. While teenagers may have lower blood pressure readings than adults, it is crucial to recognize the trend of a gradual rise in blood pressure throughout childhood and into adulthood. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they do not reflect the typical blood pressure differences observed in various populations.
5. Which of the following is a negative outcome associated with impaired mobility?
- A. Increased amounts of calcium are absorbed from circulation
- B. A drop in blood pressure occurs when rising from a sitting to a standing position
- C. The amount of mucus in the bronchi and lungs decreases
- D. The vessel walls of the circulatory system thicken
Correct answer: B
Rationale: A client with impaired mobility may develop changes in body systems that put them at risk of further illness or injury. One negative outcome associated with impaired mobility is orthostatic hypotension, where blood pressure drops significantly when moving from a sitting or lying position to a standing position. This drop in blood pressure can lead to symptoms such as dizziness or fainting. This occurs because blood circulates more slowly or pools in the distal extremities due to impaired mobility. Choice A is incorrect because increased calcium absorption is not a typical negative outcome associated with impaired mobility. Choice C is incorrect because a decrease in mucus in the bronchi and lungs is not a common negative outcome of impaired mobility. Choice D is incorrect because thickening of vessel walls in the circulatory system is not directly associated with impaired mobility.
