Which pathology is associated with an asthma condition?
- A. Chronic dilation and inflammation of the bronchi.
- B. Recurrent spasms of the airways accompanied by edema and mucus production.
- C. Progressive loss of lung function due to destruction of alveolar walls.
- D. Infection of the lung parenchyma.
Correct Answer: B
Rationale: The correct answer is B: Recurrent spasms of the airways accompanied by edema and mucus production. Asthma is characterized by bronchospasms, inflammation, swelling of the airways, and increased mucus production. This leads to airway constriction, making it difficult to breathe. Choices A, C, and D do not represent the typical pathology seen in asthma. Chronic dilation and inflammation of the bronchi (Choice A) is more characteristic of bronchiectasis, progressive loss of lung function due to destruction of alveolar walls (Choice C) is seen in conditions like emphysema, and infection of the lung parenchyma (Choice D) is more related to conditions like pneumonia.

A 55-year-old client with symptoms of osteoarthritis asks which form of exercise would be most beneficial. What is the best response by the nurse?
- A. Walking.
- B. Running.
- C. Swimming.
- D. Weight lifting.
Correct Answer: C
Rationale: The correct answer is C: 'Swimming.' Swimming is a low-impact exercise that helps maintain joint mobility and reduce pain in clients with osteoarthritis. Unlike running or weight lifting, swimming is gentle on the joints, making it an ideal choice for individuals with osteoarthritis. Walking can be beneficial too, but swimming is often preferred due to its low-impact nature. Running and weight lifting may exacerbate joint pain and should be avoided by individuals with osteoarthritis.
After a CT scan with intravenous contrast medium, a client returns to the room complaining of shortness of breath and itching. Which intervention should the nurse implement?
- A. Call respiratory therapy to administer a breathing treatment.
- B. Send for an emergency tracheostomy set.
- C. Prepare a dose of epinephrine.
- D. Review the client's complete list of allergies.
Correct Answer: C
Rationale: Preparing a dose of epinephrine is the correct intervention in this situation as the client is displaying symptoms of an anaphylactic reaction to the contrast medium used during the CT scan. Epinephrine is the first-line treatment for anaphylaxis due to its ability to reverse the symptoms rapidly. Calling respiratory therapy for a breathing treatment (Choice A) may not address the underlying allergic reaction and delay appropriate treatment. Sending for an emergency tracheostomy set (Choice B) is not indicated as the client's symptoms suggest an allergic reaction rather than airway obstruction. Reviewing the client's complete list of allergies (Choice D) is important but would not provide immediate relief for the client's current symptoms; administering epinephrine takes precedence in this situation.
A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?
- A. 16 ml/hour.
- B. 18 ml/hour.
- C. 20 ml/hour.
- D. 22 ml/hour.
Correct Answer: C
Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.
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.
Which individual has the highest risk for developing skin cancer?
- A. A 16-year-old dark-skinned female who tans in tanning beds once a week.
- B. A 65-year-old fair-skinned male who is a construction worker
- C. A 25-year-old dark-skinned male whose mother had skin cancer.
- D. A 70-year-old fair-skinned female who works as a secretary.
Correct Answer: B
Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.
