1. A nurse is caring for a client who has tuberculosis. Which of the following precautions should the nurse plan to implement when working with the client?
- A. Airborne
- B. Droplet
- C. Protective
- D. Contact
Correct answer: A
Rationale: Tuberculosis is an infectious disease that requires airborne precautions to prevent the transmission of infectious droplets. Airborne precautions involve wearing a mask, such as an N95 respirator, to protect against inhaling infectious particles. Droplet precautions are for diseases spread through respiratory droplets larger than those in airborne transmission, such as influenza. Protective precautions are not specific to respiratory infections and are more general measures to protect patients from harm. Contact precautions are used for diseases spread by direct or indirect contact, such as MRSA or C. diff infections, not for tuberculosis.
2. A nurse is assessing the heart sounds of a client who has developed chest pain that becomes worse with inspiration. The nurse auscultates a high-pitched scratching sound during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border. Which of the following heart sounds should the nurse document?
- A. Pericardial friction rub
- B. Mitral stenosis
- C. Aortic regurgitation
- D. Tricuspid stenosis
Correct answer: B
Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.
3. A community health nurse is preparing a campaign about seasonal influenza. Which of the following plans should the nurse include as a secondary prevention?
- A. Screening groups of older adults in nursing care facilities for early influenza manifestations
- B. Promoting hand hygiene to prevent the spread of influenza
- C. Administering influenza vaccinations
- D. Educating about the importance of healthy lifestyle choices to prevent influenza
Correct answer: A
Rationale: The correct answer is A. Secondary prevention aims to detect and address health issues early. Screening older adults in nursing care facilities for early influenza manifestations is an example of secondary prevention by identifying cases at an early stage. Choice B, promoting hand hygiene, is a form of primary prevention that aims to prevent the occurrence of influenza. Choice C, administering influenza vaccinations, is a form of primary prevention as well, focusing on preventing the disease before it occurs. Choice D, educating about healthy lifestyle choices, is more related to health promotion and primary prevention rather than secondary prevention.
4. A client with chronic renal failure selects scrambled eggs for breakfast. What action should the LPN/LVN take?
- A. Commend the client for selecting a high biological value protein.
- B. Remind the client that protein in the diet should be avoided.
- C. Suggest that the client also select orange juice to promote absorption.
- D. Encourage the client to attend classes on dietary management of chronic renal failure.
Correct answer: A
Rationale: The correct action is to commend the client for selecting a high biological value protein, as scrambled eggs provide a good protein source for clients with chronic renal failure. Protein is essential for maintaining muscle mass and overall health in these clients. Reminding the client to avoid protein is incorrect as it may lead to protein-energy malnutrition, which is a common concern in chronic renal failure. Suggesting orange juice for absorption is not relevant to the situation, as protein absorption is not a primary concern in this context. Encouraging the client to attend classes on dietary management of chronic renal failure is important for overall education but is not the immediate action needed in response to the client's breakfast choice.
5. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
