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 patient is receiving a high dose of intravenous azithromycin to treat an infection and taking acetaminophen for pain. The nurse should expect to review which lab values when monitoring for this drug’s side effects?

• A. Complete blood counts
• B. Electrolytes
• C. Liver enzymes
• D. Urinalysis

Correct answer: C

Rationale: When a patient is receiving a high dose of intravenous azithromycin, which is a macrolide antibiotic, in combination with acetaminophen, a potentially hepatotoxic drug, the nurse should monitor liver enzymes. High doses of macrolides when taken with hepatotoxic drugs like acetaminophen can lead to hepatotoxicity. Reviewing liver enzymes helps in early detection of liver damage. Complete blood counts (Choice A) are not typically affected by azithromycin or acetaminophen. Electrolytes (Choice B) are not directly impacted by these medications. Urinalysis (Choice D) is not specifically indicated for monitoring the side effects of azithromycin and acetaminophen combination therapy.

3. When a patient starts taking amoxicillin, which foods should the nurse instruct the patient to avoid?

• A. Green leafy vegetables
• B. Beef and other red meat
• C. Coffee, tea, and colas
• D. Acidic fruits and juices

Correct answer: D

Rationale: The correct answer is D: Acidic fruits and juices. Amoxicillin can be irritating to the stomach, so avoiding acidic fruits and juices is recommended to reduce stomach discomfort or potential interactions. Green leafy vegetables (Choice A), beef and other red meat (Choice B), and coffee, tea, and colas (Choice C) are not typically contraindicated with amoxicillin. It is important to focus on acidic foods and beverages to promote comfort and effectiveness of the medication.

4. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?

• A. Administering insulin
• B. Administering IV fluids
• C. Administering oral glucose
• D. Administering oral fluids

Correct answer: A

Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.

5. The nurse is caring for a patient who will receive 10% calcium gluconate to treat a serum potassium level of 5.9 mEq/L. The nurse performs a drug history prior to beginning the infusion. Which drug taken by the patient would cause concern?

• A. Digitalis
• B. Hydrochlorothiazide
• C. Hydrocortisone
• D. Vitamin D

Correct answer: A

Rationale: Calcium gluconate is administered to treat hyperkalemia by reducing myocardial irritability. When given to a patient taking digitalis, it can lead to digitalis toxicity. Digitalis and calcium gluconate both affect cardiac function, and their concomitant use can potentiate adverse effects. Hydrochlorothiazide, Hydrocortisone, and Vitamin D may impact potassium levels, but they do not interact with calcium gluconate in a way that would cause concern for toxicity.
