1. Which system is primarily affected by tuberculosis (Mycobacterium)?
- A. stomach (GI)
- B. heart (cardiac)
- C. lungs (respiratory)
- D. skin (integumentary)
Correct answer: C
Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.
2. Which of the following individuals is at the highest risk for suicide?
- A. 76-year-old widow with chronic renal failure
- B. 19-year-old with new SSRI therapy
- C. 28-year-old post-partum crying weekly
- D. 50-year-old client with obsessive-compulsive disorder (OCD) and depression
Correct answer: A
Rationale: The correct answer is the 76-year-old widow with chronic renal failure. Elderly individuals with chronic diseases, especially men, are at very high risk for suicide. The other choices, although they may be vulnerable populations, do not carry as high a risk for suicide. The 19-year-old with new SSRI therapy may actually have a lower risk as they are receiving treatment. The 28-year-old post-partum individual is experiencing a common emotional response after childbirth, which is not necessarily indicative of a high suicide risk. The 50-year-old with OCD and depression is at risk but not as high as elderly individuals with chronic illness.
3. How can a diet high in fiber content benefit an individual?
- A. aid in weight loss.
- B. reduce diabetic ketoacidosis.
- C. lower cholesterol.
- D. reduce the need for folate.
Correct answer: C
Rationale: A diet high in fiber content can help lower cholesterol levels by reducing the absorption of cholesterol in the bloodstream. Fiber-rich foods, like grains, apples, potatoes, and beans, can aid in this process. While fiber can aid in weight loss by promoting a feeling of fullness and aiding digestion, it is not primarily for fast weight loss. Fiber does not directly reduce the risk of diabetic ketoacidosis, which is more related to managing blood sugar levels through insulin therapy and dietary control. Folate is a B vitamin that is essential for various bodily functions and is not influenced by fiber intake. Therefore, the correct answer is to lower cholesterol, as fiber plays a significant role in this benefit.
4. What vitamin is important in preventing peripheral neuritis in a client with alcohol abuse?
- A. Vitamin D
- B. Fat-soluble vitamins
- C. B vitamins
- D. Potassium
Correct answer: B
Rationale: The correct answer is 'Fat-soluble vitamins.' Vitamin B, not Vitamin D, is crucial in preventing peripheral neuritis in individuals with alcohol abuse. Vitamin B deficiency, particularly B1 (thiamine), is commonly associated with peripheral neuritis in alcoholics. Therefore, choices A, C, and D are incorrect. Vitamin D is not directly related to peripheral neuritis, and potassium deficiency typically presents with different symptoms.
5. Which behavior by a new nurse would indicate to the charge nurse that this nurse is following standard precautions?
- A. Wearing clean gloves while performing a heel stick on an infant
- B. Wearing the same gloves for assessments of clients in the same room
- C. Wearing sterile gloves when changing the urine bag and nasogastric canister of an infected client
- D. Donning a gown when responding to a request by the family to check the IV pump on a client with rotavirus
Correct answer: A
Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.
