NCLEX RN Predictor Exam
1. When are manual hematocrits done?
- A. to monitor anemia
- B. by using a microhematocrit tube.
- C. to measure the percentage of plasma to cells.
- D. All of the above.
Correct answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
2. Patients have a right to ______________.
- A. only enough information so they can comply with care
- B. ALL of their health-related information
- C. small amounts of information so they do not get nervous
- D. moderate amounts of information unless they are old
Correct answer: B
Rationale: Patients have a legal right to access all of their health-related information. This includes details about their health condition, treatment options, test results, and any other relevant data. Providing patients with all their health-related information empowers them to make informed decisions about their care, promotes transparency in the healthcare process, and respects their autonomy. Choices A, C, and D are incorrect because they restrict the information patients should receive based on assumptions or limitations, which goes against the principle of patient autonomy and their right to access their complete health-related information.
3. A patient with Parkinson's disease is experiencing difficulty swallowing. What potential problem associated with dysphagia has the greatest influence on the plan of care?
- A. Anorexia
- B. Aspiration
- C. Self-care deficit
- D. Inadequate intake
Correct answer: B
Rationale: When a person experiences dysphagia (difficulty swallowing), the greatest concern is aspiration. Aspiration occurs when food or fluids enter the trachea and lungs instead of going down the esophagus. This can lead to serious complications such as choking, airway obstruction, and aspiration pneumonia. Anorexia (Choice A) refers to a loss of appetite, which is not the primary concern with dysphagia. Self-care deficit (Choice C) and inadequate intake (Choice D) are important considerations but do not have as direct an impact on the immediate safety and health risks associated with aspiration in dysphagia.
4. Patients exhibiting signs of cyanosis will:
- A. show signs of hyperoxia.
- B. have increased O2 saturation.
- C. have blood levels of CO2 higher than O2 levels.
- D. None of the above.
Correct answer: C
Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.
5. Which of the following is the most likely cause of constipation in a client?
- A. Postponing bowel movement when the urge to defecate occurs
- B. Intestinal infection
- C. Antibiotic use
- D. Food allergies
Correct answer: A
Rationale: The correct answer is to postpone bowel movement when the urge to defecate occurs. Clients who delay bowel movements by ignoring the urge to defecate or not evacuating promptly, such as in situations where they are not near a bathroom, are at higher risk of developing constipation. This behavior leads to a decrease in bowel movement frequency, slowed intestinal motility, and increased fecal water absorption, resulting in hard, dry stools that are difficult to pass. Intestinal infection (choice B), antibiotic use (choice C), and food allergies (choice D) are less likely to be direct causes of constipation compared to postponing bowel movements.
