1. When explaining the fecal occult blood testing procedure to a client, which of the following information should be included?
- A. Eating more protein is not necessary before testing.
- B. Multiple stool specimens may be required for testing.
- C. A red color change indicates a positive test.
- D. The specimen must not be contaminated with urine.
Correct answer: D
Rationale: The correct answer is D. When performing fecal occult blood testing, it is crucial to inform the client that the specimen must not be contaminated with urine to prevent false results. Choices A and B are incorrect because eating more protein is not required before testing, and multiple stool specimens may be necessary for accurate results, respectively. Additionally, regarding choice C, a red color change, not blue, indicates a positive test result, making it an incorrect option.
2. What information should the nurse include in the teaching plan of a client diagnosed with GERD?
- A. Sleep without using pillows
- B. Opt for five small meals throughout the day instead of three full meals with no snacks
- C. Minimize symptoms by wearing loose, comfortable clothing
- D. Engage in low-impact exercises like walking or swimming
Correct answer: C
Rationale: The correct answer is C: 'Minimize symptoms by wearing loose, comfortable clothing.' Wearing loose, comfortable clothing can help reduce pressure on the abdomen, which can alleviate GERD symptoms. Option A is incorrect as sleeping without using pillows is not a recommended practice for managing GERD. Option B is incorrect because it suggests adjusting food intake to five small meals throughout the day instead of three full meals with no snacks, which may not be suitable for everyone with GERD. Option D is incorrect as avoiding participation in any aerobic exercise program is not a standard recommendation for managing GERD; in fact, engaging in low-impact exercises like walking or swimming can be beneficial.
3. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?
- A. ST depression
- B. Inverted T wave
- C. Prominent U wave
- D. Tall peaked T waves
Correct answer: D
Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.
4. While being educated by a nurse, an assistive personnel (AP) is learning about proper hand hygiene. Which statement made by the AP indicates a good understanding of the teaching?
- A. There are times I should use soap and water rather than alcohol-based hand rub to clean my hands.
- B. I can use alcohol-based hand rub after using the restroom.
- C. Soap and water are only necessary if my hands are visibly dirty.
- D. Hand rub is always sufficient, regardless of the situation.
Correct answer: C
Rationale: Choice C is the correct answer because it demonstrates an understanding that soap and water should be used when hands are visibly dirty or when dealing with specific pathogens. Choice A is incorrect because it suggests the use of soap and water over alcohol-based hand rub without specifying the circumstances. Choice B is incorrect as it implies that using alcohol-based hand rub after using the restroom is always suitable. Choice D is incorrect because it states that hand rub is always enough, which is not true when hands are visibly soiled or when specific pathogens are present.
5. A healthcare worker with no known exposure to tuberculosis has received a Mantoux tuberculosis skin test. The nurse's assessment of the test after 62 hours indicates 5mm of erythema without induration. Which is the best initial nursing action?
- A. Review the healthcare worker's history for possible exposure to TB.
- B. Instruct the healthcare worker to return for a repeat test in 1 week.
- C. Refer the healthcare worker to a healthcare provider for isoniazid (INH) therapy.
- D. Document negative results in the healthcare worker's medical record.
Correct answer: D
Rationale: A Mantoux tuberculosis skin test without induration is considered negative. In this case, with 5mm of erythema and no induration, the result is negative, indicating no current infection. The best initial nursing action is to document these negative results in the healthcare worker's medical record. Reviewing the history for possible exposure to TB is unnecessary as the test result is negative. Instructing the healthcare worker to return for a repeat test or referring for INH therapy is not warranted when the test is negative.
