1. In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
2. A client in a physician’s office has just made an appointment for an exercise stress test. The client should be instructed to:
- A. Wear sweatpants and a heavy sweatshirt
- B. Eat a small meal just before the procedure
- C. Wear comfortable rubber-soled shoes such as sneakers
- D. Avoid consuming caffeine for 30 minutes before the procedure
Correct answer: C
Rationale: The client should wear comfortable rubber-soled shoes, such as sneakers, for the exercise stress test. This choice ensures safety and stability during the procedure. Wearing sweatpants and a heavy sweatshirt (Choice A) would not be appropriate as the client needs to wear light, loose, comfortable clothing. Eating a small meal just before the procedure (Choice B) could lead to discomfort during the test. Avoiding caffeine for 30 minutes before the procedure (Choice D) is not a specific instruction related to the attire or preparation for the test.
3. A client who is postmenopausal and has had two episodes of bacterial urethritis in the last 6 months asks, “I never have urinary tract infections. Why is this happening now?” How should the nurse respond?
- A. Your immune system becomes less effective as you age.
- B. Low estrogen levels can make the tissue more susceptible to infection.
- C. You should be more careful with your personal hygiene in this area.
- D. It is likely that you have an untreated sexually transmitted disease.
Correct answer: B
Rationale: Low estrogen levels in postmenopausal women decrease moisture and secretions in the perineal area, causing tissue changes that predispose them to infection, including urethritis. This is a common reason for urethritis in postmenopausal women. While immune function does decrease with aging and sexually transmitted diseases can cause urethritis, the most likely reason in this case is the low estrogen levels. Personal hygiene practices are usually not a significant factor in the development of urethritis.
4. What is the most common symptom of hypoglycemia that the nurse should teach the diabetic client to recognize?
- A. Nervousness
- B. Anorexia
- C. Kussmaul's respirations
- D. Bradycardia
Correct answer: A
Rationale: Nervousness is the most common symptom of hypoglycemia. It is often accompanied by other signs such as weakness, perspiration, confusion, and palpitations. Anorexia (lack of appetite) is not a typical symptom of hypoglycemia; it is more commonly associated with hyperglycemia. Kussmaul's respirations are a deep and labored breathing pattern seen in diabetic ketoacidosis, not hypoglycemia. Bradycardia (slow heart rate) is not a typical symptom of hypoglycemia; tachycardia (fast heart rate) is more commonly associated with hypoglycemia due to the release of catecholamines in response to low blood sugar.
5. In a patient with deep vein thrombosis (DVT), which of the following symptoms would be expected?
- A. Chest pain.
- B. Shortness of breath.
- C. Coughing up blood.
- D. Cyanosis.
Correct answer: B
Rationale: Shortness of breath is a common symptom of deep vein thrombosis (DVT) due to the risk of a pulmonary embolism. DVT occurs when a blood clot forms in a deep vein, usually in the legs. If a portion of the clot breaks loose and travels to the lungs, it can cause a pulmonary embolism, leading to symptoms like shortness of breath. Chest pain is more commonly associated with conditions like a heart attack or pulmonary embolism itself. Coughing up blood is a symptom more indicative of conditions such as pulmonary embolism or lung cancer. Cyanosis, which is a bluish discoloration of the skin or mucous membranes due to poor oxygenation, can be seen in severe cases of pulmonary embolism but is not a typical symptom of DVT.
