1. What is the primary action of insulin in the body?

• A. To lower blood pressure.
• B. To promote the absorption of glucose into cells.
• C. To increase blood glucose levels.
• D. To decrease blood glucose levels.

Correct answer: B

Rationale: The correct answer is B: To promote the absorption of glucose into cells. Insulin facilitates the uptake of glucose by cells, thereby decreasing blood glucose levels. Choice A is incorrect as insulin does not directly affect blood pressure. Choice C is inaccurate as insulin works to lower, not increase, blood glucose levels. Choice D is incorrect because insulin's primary role is to lower, not increase, blood glucose levels by promoting glucose uptake into cells.

2. A client is being taught about self-catheterization in the home setting. Which statements should the nurse include in this client’s teaching? (Select all that apply.)

• A. Wash your hands before and after self-catheterization.
• B. Use lubricant on the tip of the catheter before insertion.
• C. A & B
• D. Self-catheterize at least twice a day or every 12 hours.

Correct answer: C

Rationale: In teaching a client about self-catheterization, it is essential to emphasize proper hand hygiene before and after the procedure to prevent infections. Using lubricant on the catheter helps with insertion and reduces discomfort. Therefore, statements A and B are correct and should be included in the client's teaching. Option D is incorrect because self-catheterization frequency should be individualized based on the client's needs, and a specific time frame like every 12 hours may not be suitable for everyone. Choosing a smaller lumen catheter is preferred over a larger one. Self-catheterization should not be limited to a specific time frame but should be based on the individual's needs and voiding patterns. Therefore, option C is the correct choice as it includes the two essential statements for teaching self-catheterization in the home setting.

3. What is the most common symptom of gastroesophageal reflux disease (GERD)?

• A. Heartburn.
• B. Nausea.
• C. Abdominal pain.
• D. Vomiting.

Correct answer: A

Rationale: The correct answer is A: Heartburn. Heartburn is the most common symptom of GERD as it occurs due to the reflux of stomach acid into the esophagus. This leads to a burning sensation in the chest that can worsen after eating, lying down, or bending over. Choice B, Nausea, is not typically the most common symptom of GERD, although it can occur in some cases. Choice C, Abdominal pain, is not a primary symptom of GERD and is more commonly associated with other gastrointestinal conditions. Choice D, Vomiting, is also not the most common symptom of GERD, although it can occur in severe cases or as a result of complications.

4. While assisting a client with a closed chest tube drainage system to move from bed to a chair, the chest tube gets caught on the chair leg and becomes dislodged from the insertion site. What is the immediate priority for the nurse?

• A. Contacting the physician
• B. Reinserting the chest tube
• C. Transferring the client back to bed
• D. Covering the insertion site with a sterile occlusive dressing

Correct answer: D

Rationale: The immediate priority for the nurse when a chest tube becomes dislodged from the insertion site is to cover the site with a sterile occlusive dressing. This action helps prevent air from entering the pleural space, which could lead to a pneumothorax. The nurse should then perform a respiratory assessment to monitor the client's breathing, assist the client back into bed to a position of comfort, and notify the physician. Reinserting the chest tube is a task for the physician, not the nurse, as it requires specific training and expertise.

5. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?

• A. Drugs with a broad spectrum
• B. Drugs with a narrow spectrum
• C. Drugs with a broad therapeutic index
• D. Drugs with a narrow therapeutic index

Correct answer: D

Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
