Which of the following is the most numerous type of white blood cell (WBC)?
- A. Neutrophil
- B. Basophil
- C. Eosinophil
- D. Lymphocyte
Correct Answer: A
Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.

Which of the following guidelines should a nursing instructor provide to nursing students who are now responsible for assessing their clients?
- A. Assessment data about the client should be collected continuously.
- B. Assess your client after receiving the nursing report and again before giving a report to the next shift of nurses.
- C. Assess your client at least hourly if the client’s vital signs are unstable, and every two hours if the vital signs are stable.
- D. Assessment data should be collected prior to the physician rounding on the unit.
Correct Answer: A
Rationale: The correct answer is A because continuous assessment allows for timely identification of changes in the client's condition. This is crucial for providing appropriate and timely interventions. Assessing the client only at specific times (choices B and C) may lead to missing important changes. Choice D is incorrect because assessments should not be limited to physician rounds; they should be ongoing to ensure comprehensive care.
Why is heart biopsy performed throughout a clients lifetime after heart transplantation?
- A. To detect rejection
- B. To check the heart functionality
- C. To check rate of the heartbeat
- D. To check for heart tumor CARING FOR CLIENTS WITH HYPERTENSION
Correct Answer: A
Rationale: The correct answer is A: To detect rejection. After heart transplantation, heart biopsy is performed to monitor for rejection, a common complication. Tissue samples are examined for signs of rejection, such as inflammation. This is crucial for timely intervention to prevent rejection-related complications.
Other choices are incorrect:
B: Heart functionality is typically assessed through imaging tests like echocardiograms, not biopsy.
C: Heart rate monitoring can be done through non-invasive methods like electrocardiograms, not biopsy.
D: Checking for heart tumors is not a primary purpose of heart biopsy post-transplantation.
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.
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.
A patient expresses fear of going home and being alone. Vital signs are stable and the incision is nearly completely healed. What can the nurse infer from the subjective data?
- A. The patient can now perform the dressing changes without help.
- B. The patient can begin retaking all of the previous medications.
- C. The patient is apprehensive about discharge.
- D. The patient’s surgery was not successful.
Correct Answer: C
Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This is supported by stable vital signs and nearly healed incision, suggesting physical recovery. Choice A is incorrect as fear of being alone does not necessarily mean the patient can perform dressing changes independently. Choice B is incorrect as resuming medications is not related to the patient's fear of being alone. Choice D is incorrect as there is no evidence to suggest the surgery was unsuccessful based on the information provided.
