1. The nurse is caring for a patient who has a right-sided chest tube after a right lower lobectomy. Which nursing action can the nurse delegate to the unlicensed assistive personnel (UAP)?
- A. Document the amount of drainage every eight hours
- B. Obtain samples of drainage for culture from the system
- C. Assess patient pain level associated with the chest tube
- D. Check the water-seal chamber for the correct fluid level
Correct answer: A
Rationale: The correct answer is to document the amount of drainage every eight hours. UAP education typically includes tasks related to documentation of intake and output. Obtaining samples of drainage for culture and assessing patient pain level are nursing responsibilities that require licensed nursing personnel's education and scope of practice. Checking the water-seal chamber for the correct fluid level also falls under the nursing role, as it involves monitoring and maintaining the chest tube system, which requires nursing knowledge and training.
2. What are Korotkoff sounds?
- A. Sounds noted during diastole.
- B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
- C. Sounds only noted by skilled cardiologists.
- D. Distinct sounds which are classified into 6 phases.
Correct answer: B
Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
3. A patient in a clinic has been diagnosed with hepatitis A. What is the most likely route of transmission?
- A. Sexual contact with an infected partner
- B. Contaminated food
- C. Blood transfusion
- D. Illegal drug use
Correct answer: B
Rationale: The correct answer is contaminated food. Hepatitis A is primarily transmitted through the fecal-oral route, often through the ingestion of contaminated food or water. It is caused by the Hepatitis A virus (HAV), which is a single-stranded, positive-sense RNA virus. Sexual contact with an infected partner is more commonly associated with hepatitis B and C. Blood transfusion is a potential route for hepatitis B and C transmission due to bloodborne pathogens. Illegal drug use, particularly involving shared needles, is a common route for hepatitis C transmission.
4. Assuming that an elderly patient will have a difficult time understanding the directions for how to take medication is an example of:
- A. Prejudice
- B. Stereotyping
- C. Encoding
- D. Rationalization
Correct answer: B
Rationale: Stereotyping is defined as providing a generalization about a person based on their culture or characteristics. In this scenario, assuming that an elderly patient will have difficulty understanding medication directions solely based on their age is an act of stereotyping. The healthcare provider is attributing a generalized trait to the patient without considering individual differences. Prejudice, on the other hand, involves forming a negative opinion about someone based on their heritage or culture, which is not evident in this situation. Encoding refers to the process of converting information into a form that can be stored in memory, and rationalization involves justifying one's behavior or decisions with logical reasons, neither of which are applicable in this context.
5. The nurse is unable to palpate the right radial pulse on a patient. What would the nurse do next?
- A. Auscultate over the area with a fetoscope.
- B. Use a goniometer to measure the pulsations.
- C. Use a Doppler device to check for pulsations over the area.
- D. Check for the presence of pulsations with a stethoscope.
Correct answer: C
Rationale: When a nurse is unable to palpate a radial pulse, the next step is to use a Doppler device to check for pulsations over the area. Doppler devices are specifically designed to augment pulse or blood pressure measurements. Auscultating with a fetoscope is used to listen to fetal heart tones and is not relevant in this scenario. Goniometers are used to measure joint range of motion and are not used to assess pulses. Stethoscopes are primarily used to auscultate breath, bowel, and heart sounds, not to check for pulsations in peripheral pulses. Therefore, the correct course of action when unable to palpate a pulse is to utilize a Doppler device to assess for pulsations in the radial pulse area.
