1. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?
- A. ''This action of my lips helps to keep my airway open.''
- B. ''I can expel more air when I pucker up my lips to breathe out.''
- C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
- D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''
Correct answer: D
Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.
2. The healthcare professional is preparing to percuss the abdomen of a patient. What characteristic of the underlying tissue does percussion assess?
- A. Turgor
- B. Texture
- C. Density
- D. Consistency
Correct answer: C
Rationale: Percussion is a technique used to assess the density of underlying organs by producing sounds that help determine their location and size. Turgor, texture, and consistency are primarily assessed through palpation, not percussion. Turgor refers to skin elasticity, texture pertains to the feel of the tissue surface, and consistency relates to the firmness or resistance of the tissue.
3. Which of the following safety precautions should the nurse discuss when working with an immunocompromised client?
- A. Avoid canned foods and increase consumption of fresh fruits and vegetables
- B. Hand-wash utensils after use and allow them to air dry
- C. Only drink tap water that has been filtered or boiled before consumption
- D. Never eat meals prepared in restaurants
Correct answer: C
Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.
4. When checking for proper blood pressure cuff size, which guideline is correct?
- A. The standard cuff size is appropriate for all sizes.
- B. The length of the rubber bladder should equal 80% of the arm circumference.
- C. The width of the rubber bladder should equal 80% of the arm circumference.
- D. The width of the rubber bladder should equal 40% of the arm circumference.
Correct answer: D
Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.
5. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)
- A. Increased pulse rate, normal EKG
- B. Decreased pulse rate, abnormal EKG
- C. Tachycardia, poor EKG graph
- D. Bradycardia, poor EKG graph
Correct answer: C
Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.
