The presence of anemia is characterized by a/an:
- A. Increase of red blood cells
- B. Increased hemoglobin
- C. Decrease in the concentration of red blood
- D. Decreased blood count cells
Correct Answer: C
Rationale: Step-by-step rationale:
1. Anemia is a condition where there is a decrease in the concentration of red blood cells.
2. Red blood cells carry oxygen to the body's tissues, so a decrease in their concentration leads to reduced oxygen delivery.
3. This decrease in red blood cell concentration can be measured through a decrease in hematocrit levels.
4. Choices A and B are incorrect because anemia involves a decrease, not an increase, in red blood cells and hemoglobin.
5. Choice D is incorrect as it mentions "decreased blood count cells," which is not a specific term related to anemia.
Summary: The correct answer is C because anemia is characterized by a decrease in the concentration of red blood cells, leading to reduced oxygen delivery, while the other choices are incorrect due to inaccuracies in describing anemia.

When the LPN is assisting the patient to use an incentive spirometer, which of the following actions by the patient indicates that the patient needs further teaching on how to use the spirometer?
- A. Taking two normal breaths before use.
- B. Sitting upright before use.
- C. Inhaling deeply to reach target.
- D. Exhaling deeply to reach target.
Correct Answer: D
Rationale: The correct answer is D because exhaling deeply before using the spirometer is incorrect. The purpose of the incentive spirometer is to encourage deep inhalation to improve lung function. Exhaling deeply before using the spirometer goes against this goal and may hinder the effectiveness of the device. Choices A, B, and C are all correct actions when using the spirometer. Taking two normal breaths helps to prepare the lungs, sitting upright optimizes lung expansion, and inhaling deeply to reach the target helps to improve lung ventilation.
Which of the following nursing actions is appropriate when a patient returns to his or her room after a bronchoscopy?
- A. Order a meal because the patient has been nil per os (NPO) for 8 hours.
- B. Encourage fluids to flush dye from the patient’s system.
- C. Monitor the patient for return to consciousness.
- D. Check for a gag reflex before allowing the patient to drink.
Correct Answer: D
Rationale: The correct answer is D - Check for a gag reflex before allowing the patient to drink. This is important after a bronchoscopy to prevent aspiration. Step 1: Assessing gag reflex ensures the patient can protect their airway. Step 2: Aspiration risk is high post-bronchoscopy due to sedation and possible throat numbness. Step 3: Allowing fluids without confirming gag reflex can lead to aspiration pneumonia. Other choices are incorrect. A: Ordering a meal immediately is inappropriate after NPO period. B: Encouraging fluids without assessing gag reflex may lead to aspiration. C: Monitoring consciousness is important but not directly related to post-bronchoscopy care.
During the nursing interview Toni minimizes her visual problems talks about remaining in school to attempt advanced degrees, requests information about full-time jobs in nursing and mentions her desire to have several more children. The nurse recognizes her emotional responses as being:
- A. An example of inappropriate euphoria characteristic of the disease process f. A reflection of coping mechanisms used to deal with the exacerbation of her illness g. Indicative of the remission phase of her chronic illness h. Realistic for her current level of physical functioning
Correct Answer: B
Rationale: Step 1: The scenario describes Toni minimizing her visual problems, planning advanced degrees, seeking full-time jobs, and wanting more children.
Step 2: Choice B is correct because it recognizes Toni's behavior as a coping mechanism to deal with her illness.
Step 3: Minimizing visual problems and focusing on future goals can be a way for Toni to maintain a positive outlook and cope with her challenges.
Step 4: Choices A, C, and D are incorrect because they do not address Toni's behavior as a coping mechanism. Choice A mentions euphoria, which is not supported by the scenario. Choice C and D do not acknowledge Toni's coping mechanism but instead focus on different aspects like disease process and physical functioning.
Mrs. Go a 75-year old female suffered a fdall and is diagnosed with a herniated nucleus pulposus at the C4-C5 interspace, and a second st the C5-C6 interspace.Which of the following findings would the nurse expect to discover during the assessment?
- A. constant, throbbing headaches
- B. clonus in the lower extremities
- C. Numbness of the face
- D. pain in the scapular region
Correct Answer: D
Rationale: The correct answer is D: pain in the scapular region. This is because a herniated nucleus pulposus at the C4-C5 and C5-C6 interspaces typically results in pain radiating from the neck to the scapular region due to nerve compression at those levels. The other choices are incorrect as constant, throbbing headaches are not typically associated with this specific diagnosis, clonus in the lower extremities is more indicative of lower spinal cord involvement, and numbness of the face is not a common symptom of herniated discs at these levels.
To provide safe care for Mrs. Zeno, it is important for the nurse to check the bedside for the presence of:
- A. A tracheostomy set
- B. A hypothermia blanket
- C. An intravenous set-up
- D. A syringe and edrophonium HCl(Tensilon)
Correct Answer: B
Rationale: The correct answer is B: A hypothermia blanket. This is important because hypothermia can lead to complications such as shivering, increased risk of infection, and altered drug metabolism. Checking for the hypothermia blanket ensures Mrs. Zeno's temperature is regulated, promoting safety.
A: A tracheostomy set is not directly related to Mrs. Zeno's immediate safety unless she has a tracheostomy in place.
C: An intravenous set-up is important for administering medications, fluids, or blood products, but it is not directly related to Mrs. Zeno's safety at the bedside.
D: A syringe and edrophonium HCl(Tensilon) is specific to a diagnostic test for myasthenia gravis, which may not be relevant to Mrs. Zeno's current condition or safety.
