A nurse is gathering information from a patient who is on metoprolol. What should the nurse anticipate as a possible outcome?
Elevated blood glucose levels.
Increased blood pressure.
Reduced bronchospasms.
Lowered heart rate.
The Correct Answer is D
Choice A rationale
Metoprolol is a beta-blocker that affects the heart and circulation. It does not typically cause elevated blood glucose levels.
Choice B rationale
Metoprolol is used to treat high blood pressure, not increase it. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
Choice C rationale
Metoprolol does not typically reduce bronchospasms. In fact, it can sometimes cause breathing problems such as shortness of breath, cough, and wheezing.
Choice D rationale
Metoprolol is known to lower heart rate. This is one of the ways it helps to reduce blood pressure and relieve strains on the heart.

Correct Answer is C
Explanation
Choice A rationale
Discontinuing the nasogastric tube is not the best action to take at this time. The nasogastric tube may be necessary for decompression of the stomach or administration of medications and should not be removed without a specific order from the healthcare provider.
Choice B rationale
Providing the client with ice chips is not the most appropriate action. The client is kept NPO (nothing by mouth) before surgery to prevent aspiration during anesthesia. Therefore, giving the client ice chips could increase the risk of aspiration.
Choice C rationale
Starting the prescribed antibiotic is the correct action. Cefazolin is an antibiotic that is often given before surgery to prevent postoperative infections. Administering this medication as ordered can help to ensure that the client is adequately prepared for surgery.
Choice D rationale
While reinforcing preoperative teaching is an important part of nursing care, it is not the most immediate action that should be taken in this situation. The client’s physical preparation for surgery, including the administration of prescribed medications, should be prioritized.
Correct Answer is B
Explanation
Choice A rationale
While it’s important to prepare for a colonoscopy by cleaning out the colon, drinking full liquids until 6 hours before the procedure may not be recommended. The colon needs to be empty to allow the doctor to view it clearly during the colonoscopy. Therefore, this choice is incorrect.
Choice B rationale
Moderate sedation is often used during a colonoscopy. This means you’ll be relaxed and somewhat drowsy, but you’ll still be awake. You might not remember much about the actual procedure because of the sedative. Therefore, this choice is correct.
Choice C rationale
During a colonoscopy, you will likely start by lying on your left side. However, you may be asked to adjust your position during the procedure to allow the doctor to better examine certain parts of your colon. Therefore, this choice is incorrect.
Choice D rationale
Warming the liquid bowel preparation before drinking it is not typically recommended. The bowel preparation involves drinking a solution that helps clear out the colon, but it doesn’t need to be warmed. Therefore, this choice is incorrect.
