1. A patient has suddenly developed shortness of breath and appears to be in significant respiratory distress. After calling the physician and placing the patient on oxygen, which of these actions is the best for the nurse to take when further assessing the patient?
- A. Count the patient's respirations.
- B. Bilaterally percuss the thorax, noting any differences in percussion tones.
- C. Call for a chest x-ray and wait for the results before beginning an assessment.
- D. Inspect the thorax for any new masses and bleeding associated with respirations.
Correct answer: B
Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.
2. When measuring a patient's body temperature, what factor should be considered that can influence the temperature?
- A. Constipation
- B. Diurnal cycle
- C. Nocturnal cycle
- D. Patient's emotional state
Correct answer: B
Rationale: When measuring body temperature, it is essential to consider factors that can influence it. The diurnal cycle, which refers to the body's natural temperature variations throughout a 24-hour period, can impact body temperature readings. Factors like exercise, age, and environment can also affect body temperature. Constipation does not directly influence body temperature. The 'nocturnal cycle' is not a recognized term in relation to body temperature. While a patient's emotional state can affect vital signs, it is not a primary factor in influencing body temperature measurements.
3. Which principle of body mechanics may help to reduce the risk of a back injury?
- A. Maintain a wide base of support
- B. Bend from the knees, not the waist
- C. Keep the back straight while lifting
- D. Push or pull objects rather than lifting
Correct answer: C
Rationale: Proper body mechanics are crucial to prevent injuries, especially for professions involving lifting and moving objects. Keeping the back straight while lifting is essential to reduce the risk of back injuries as it helps maintain the spine's natural alignment and prevents excessive strain on the back muscles. Choosing choices A, B, and D would increase the risk of back injury. Maintaining a wide base of support provides stability, bending from the knees instead of the waist protects the lower back, and pushing or pulling objects reduces the strain on the back muscles, all contributing to preventing back injuries.
4. A patient is asked to abduct her arms. Which of the following accurately describes her arm movement?
- A. She moves her arms away from her trunk
- B. She moves her arms toward her trunk
- C. She rotates her arms at the wrists while holding them away from her body
- D. She crosses her arms over her abdomen
Correct answer: A
Rationale: Abduction refers to moving a body part away from the midline of the body. In this case, when the patient abducts her arms, she is moving them away from her trunk. Choice A is correct. Choices B, C, and D are incorrect. Choice B describes adduction, which is the movement of a body part toward the midline. Choice C describes wrist rotation, not arm abduction. Choice D describes crossing the arms over the abdomen, which is not the movement associated with abduction.
5. A client is taking a walk down the hallway when she suddenly realizes that she needs to use the restroom. Although she tries to make it to the bathroom on time, she is incontinent of urine before reaching the toilet. What type of incontinence does this situation represent?
- A. Relex incontinence
- B. Urge incontinence
- C. Total incontinence
- D. Functional incontinence
Correct answer: D
Rationale: Functional incontinence occurs when a client develops an urge to void but may not be able to reach the toilet in time. In this scenario, the client had the urge to use the restroom but was unable to make it in time, leading to incontinence. Functional incontinence may be related to conditions that cause the client to forget bladder sensation until the last minute, such as cognitive changes, or the client may have mobility problems that prevent her from reaching the bathroom in time. Choice A, Reflex incontinence, is incorrect as reflex incontinence is characterized by the involuntary loss of urine due to hyperreflexia of the detrusor muscle. Choice B, Urge incontinence, is not the correct answer as urge incontinence is the involuntary loss of urine associated with a strong desire to void. Choice C, Total incontinence, is also incorrect as it refers to the continuous and unpredictable loss of urine, not specifically related to the inability to reach the toilet in time.
