1. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
2. The healthcare provider notes that a client has a new prescription for 20 mEq of potassium. The IV site is inflamed but not tender, and has a blood flashback. What action should the healthcare provider take?
- A. Obtain a liter of normal saline with 20 mEq of KCl
- B. Contact the healthcare provider to clarify the prescription
- C. Withhold the prescription medication until a new IV is started
- D. Fax the prescription to the pharmacy for immediate dispensing
Correct answer: B
Rationale: The healthcare provider should contact the prescriber to clarify the prescription because an inflamed IV site may indicate potential issues with administering the medication. It is important to ensure that the prescription is appropriate and safe for the client before proceeding with administration. Option A is incorrect because administering potassium through an inflamed IV site can lead to further complications. Option C is not the best course of action as clarifying the prescription first is essential. Option D is also incorrect as the focus should be on ensuring the safety of the client before dispensing the medication.
3. A client with a diagnosis of generalized anxiety disorder is prescribed fluvoxamine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Insomnia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Fluvoxamine is known to cause drowsiness as a potential side effect. Patients should be advised to avoid activities like driving that require alertness until they understand how the medication affects them. Dry mouth, insomnia, and headache are potential side effects of other medications used for anxiety disorders but are not typically associated with fluvoxamine.
4. A client with hypertension is prescribed amlodipine. The nurse should monitor for which potential adverse effect?
- A. Peripheral edema
- B. Bradycardia
- C. Hypertension
- D. Increased appetite
Correct answer: A
Rationale: Corrected Rationale: Amlodipine is known to cause peripheral edema as a potential adverse effect due to its vasodilatory properties. This can lead to fluid accumulation in the extremities. Monitoring for peripheral edema in patients taking amlodipine is crucial to identify and manage this side effect promptly. Choices B, C, and D are incorrect because amlodipine is not associated with causing bradycardia, hypertension (as the patient already has hypertension), or increased appetite as adverse effects.
5. A client with a history of deep vein thrombosis is prescribed apixaban. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: The correct answer is A: Increased risk of bleeding. Apixaban is an anticoagulant medication that works by preventing blood clots. While this is beneficial for individuals with a history of deep vein thrombosis, it also increases the risk of bleeding. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, or blood in the urine or stool. Monitoring for bleeding is crucial to ensure the client's safety and to take appropriate actions if necessary. Choices B, C, and D are incorrect because apixaban does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. The primary concern when administering apixaban is monitoring for potential bleeding complications.
