1. Which action is appropriate for the nurse to delegate to unlicensed assistive personnel (UAP)?
- A. Listen to a patient's lung sounds for wheezes or rhonchi.
- B. Label specimens obtained during percutaneous lung biopsy.
- C. Instruct a patient about how to use home spirometry testing.
- D. Measure induration at the site of a patient's intradermal skin test.
Correct answer: B
Rationale: Labeling specimens obtained during a percutaneous lung biopsy is a task that can be appropriately delegated to unlicensed assistive personnel (UAP) as it does not require nursing judgment. UAP can perform this task safely under the supervision of a nurse. Listening to a patient's lung sounds for wheezes or rhonchi, instructing a patient about how to use home spirometry testing, and measuring induration at the site of a patient's intradermal skin test all require nursing judgment and interpretation of findings. These tasks should be performed by licensed nursing personnel to ensure accurate assessment and appropriate intervention.
2. Which of the following is an anthropometric measurement?
- A. Blood pressure
- B. Temperature
- C. Pulse Rate
- D. Weight
Correct answer: D
Rationale: Anthropometric measurements relate to the size, weight, and proportions of the human body. Weight is a key anthropometric measurement as it directly reflects body mass, making it the correct choice. Blood pressure, temperature, and pulse rate are physiological measurements that do not specifically pertain to body size or proportion, hence making them incorrect choices in the context of anthropometric measurements.
3. In which of the following ways can a healthcare provider promote the sense of taste for an older adult?
- A. Mixing foods together on the dinner tray
- B. Avoiding cologne, air fresheners, or room deodorizers
- C. Encouraging the client to chew food thoroughly
- D. Discouraging the use of salt or seasonings with prepared food
Correct answer: C
Rationale: As individuals age, their sense of taste may diminish, impacting the enjoyment of eating. One effective way for a healthcare provider to promote the sense of taste for an older adult is by encouraging them to chew food thoroughly. Thorough chewing increases the contact of food with the taste buds, enhancing the chances of experiencing the flavors. Mixing foods together on the dinner tray may not necessarily enhance taste perception. Avoiding strong scents like cologne, air fresheners, or room deodorizers is more related to olfactory senses rather than taste. Discouraging the use of salt or seasonings can further diminish the taste experience for older adults who may already have reduced taste sensitivity.
4. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?
- A. PT/INR
- B. CBC
- C. PTT
- D. WBC
Correct answer: A
Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
5. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?
- A. 10
- B. 70
- C. 80
- D. 100
Correct answer: B
Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.
