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. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.

3. The client with chronic renal failure who is on a low-sodium diet should avoid which of the following foods?

• A. Fresh fruits.
• B. Canned soups.
• C. Lean meats.
• D. Whole grain bread.

Correct answer: B

Rationale: Canned soups are high in sodium, which can lead to fluid retention and hypertension in clients with chronic renal failure who are on a low-sodium diet. Fresh fruits, lean meats, and whole grain bread are generally lower in sodium and can be included in a low-sodium diet. Lean meats provide essential protein, fresh fruits offer vitamins and minerals, and whole grain bread provides fiber, making them suitable choices for individuals with chronic renal failure.

4. A client who has undergone pleural biopsy is being monitored by a nurse. Which finding indicates a potential complication for the client?

• A. Warm, dry skin
• B. Mild pain at the biopsy site
• C. Complaints of shortness of breath
• D. Capillary refill time of less than 3 seconds

Correct answer: C

Rationale: Complaints of shortness of breath are a concerning finding post-pleural biopsy, as they may indicate a complication such as a pneumothorax or hemothorax. Shortness of breath can be a sign of respiratory distress that requires immediate attention. Warm, dry skin, mild pain at the biopsy site, and a capillary refill time of less than 3 seconds are not typically associated with immediate complications following a pleural biopsy. Warm, dry skin may be a normal finding, mild pain can be expected at the biopsy site, and a capillary refill time of less than 3 seconds is within normal limits.

5. A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: Erythromycin is the drug of choice for treating Mycoplasma pneumonia. Mycoplasma pneumonia is typically sensitive to macrolide antibiotics, with erythromycin being one of the first-line agents. Azithromycin and clarithromycin are also effective in treating Mycoplasma pneumonia, but erythromycin is specifically mentioned as the drug of choice in this context. Fidaxomicin, on the other hand, is not indicated for the treatment of Mycoplasma pneumonia and is primarily used to treat Clostridium difficile infections.
